  • How to Use

    This application has three modes for different purposes. You can switch the mode by using the "Mode Tab" at the bottom of the "Main Screen."


    • "Distinguish Color" mode

      This mode is for distinguishing between difficult to distinguish colors.

    • "Find Color" mode

      This mode is for finding colors which are similar to a specified color on the screen or by a color name.

    • "Simulation" mode

      This mode makes a simulation image according to a color vision type for showing it to the person of type C (Common type). It may be helpful to understand the colors which are hard to distinguish for various color vision types. Since a simulation image is not necessarily exact, please use it as a rough indication.


    Main Screen

    All fundamental operations are performed in the "Main Screen." The upper part has an information area. The right and left side in the upper half of the screen have some operation buttons. The parts required for fundamental operation are located in the lower part of the screen.
    When a user does not touch the screen for 10 seconds or more, all texts and buttons except "Cursor", "Color Name Pop-up", "Chromaticity Diagram", and "Basic 11 Colors Ribbon" are made un-displayed. These are re-displayed by tapping the screen.

    Status Information


    • (Upper left) Zone: Displays the range of a color zone as "Start Position~End Position".
    • (Center) Type: Displays the color vision type.
    • (Upper right) Vary: Displays the color changing parameters in the color zone as "Variation/Direction".
    • (Center of the 2nd line) Zoom: Displays the magnification ratio in %.

    Buttons

    • Setting Button
      Opens the "Settings Screen" for various settings.

    • Display Color Name Button
      Displays the "Color Name Pop-up" for showing a color name at the position of the cursor on the screen (Cursor color).

    • Display Chromaticity Diagram Button
      Displays the "xy" or the "u'v'" Chromaticity Diagram in the upper right screen.
      Only the range of sRGB in chromaticity diagrams are colored. The current color changing method is also effective on the diagrams similar to the image on the "Main Screen." This is convenient to grasp how and which range of color is changed according to the value of the sliders and buttons.

    • Simulation Button
      Displays a simulated image of each type of color vision. This button is used on modes other than "Simulation" mode. A simulated image can be made from a modified image in "Distinguish Color" mode and "Find Color" mode in real-time. The value of the "Simulation Color Vision Type" and the "Simulation Intensity" on the "Simulation" mode are used for simulation.

    • Save Image Button
      Saves a currently displayed image to a photo album after changing the color. It is also possible to superimpose various kinds of parametric information on the image by turning ON the "Save Image with Params" in the "Settings."

    • Switch Camera/Photo Album Button
      Displays the "Imame Source Pop-up Buttons" to choose the source of the image from "Rear Camera", "Front Camera" (only loading model) or "Photo Album."

    • Torch(Flashlight) Button
      Turns on a torch(flashlight). Appears only in a torch light loading model. Even if this button is ON, it is turned OFF automatically when the application is operating in the background, or while in the "Freeze" state by "Freeze Button" or long press gesture. It becomes disabled when the image source is "Photo Album."

    • Freeze Button
      Stops a video capture and displays a still image ("Freeze" state). Nothing changes when the image source is a "Photo Album." It is possible to scroll an image with the pan gesture in the "Freeze" state. Please use it in combination with image scaling by using the pinch gesture. Changing the color, displaying the color name, and moving the cursor are also possible in the "Freeze" state.

    • Image Source Pop-up Buttons
      Chooses the source of the image from " Rear Camera", " Front Camera" (only loading model) or " Photo Album."

    Cursor


      The round mark used in order to specify the position on the screen. It is displayed when the "Find Color" mode or the "Display Color Name Button" is set to ON. The cursor keeps the color of the portion of an image and is called the "Cursor Color." It can be moved by tapping.

    Color Name Pop-up


      Displays 4 lines describing the "Cursor Color" information which is specified by the "Color Information" in the "Settings." It shows "CIELAB", "Munsell (approximate value)", "JIS(Japanese Industrial Standards) Generic Color Name" and "JIS Common Color Name (nearest)" by default.
      The weighted average of 5x5 pixels in every direction calculated by Gaussian filter is used for deciding the color at the cursor position.
      The color value or name displayed here is not necessarily exact, although it is calculated based on several standards under the assumption of using sRGB color space and D65 light sources.

    Mode Tab


      Switches between the "Distinguish Color" Mode, the "Find Color" Mode, and the "Simulation" Mode.


    "Distinguish Color" Mode


      This mode is used by persons of P, D, or T color vision type in order to distinguish between difficult to distinguish colors. This application sets up a color zone which can divide confusing colors, and change them to a color which is more easily distinguishable while maintaining the original color as much as possible.
      A division of the color zone and the color to be changed are calculated in the uniform color space in accordance with human feeling.
      In order for the color changed image to be easy to understand, it will be displayed on the screen alternately with the original image. To the observer, it will appear to be blinking.
    • "Distinguish Color" Toolbar

      "Left Pop-up Button", "Zone Range Slider", "Right Pop-up Button"

    • Left Pop-up Button

      Displays "Preset Pop-up Menu."

    • Zone Range Slider (possible value: (0.0~1.0)~(0.0~1.0))

      A slider which specifies the range of a color zone in which the colors are changed. It has two thumb(knob) controls on the right and left. The leftmost (value 0.0) area contains green, and the rightmost (value 1.0) area contains red (it is called the zone coordinate).
      The zone coordinate of the starting position of a color zone is set up by the left thumb, and the zone coordinate of the end position is set by the right thumb. If the area near the center of both thumbs (blue portion) is touched, the whole can be moved simultaneously.
      The color of the slider is also reversed when the "Reverse Color Zone" is ON in the "Settings." When the "Auto Color Zone" is ON in the "Setup", it becomes yellow between the thumbs. According to the color vision type in the "Settings," the color zone is forms the best shape where the person tends to distinguish color. You can check which color actually changes by the range of the color zone. You can show a chromaticity diagram by pressing the "Display Chromaticity Diagram Button."

    • Right Pop-up Button

      Turns ON and OFF the display of the "Color Vision Type Selector" and the "Color Change Two-dimensional Slider (Distinguish Color)."

    • Preset Pop-up Menu

      A pop-up menu for selecting a preset. There are 8 presets named Preset 1~8, which can store a set of parameters used in the "Distinguish Color" Mode. When a preset name on the preset menu is tapped, the preset is selected and parameters are loaded and reflected immediately.
      Moreover, when a long press gesture in 2 seconds or more is performed on a preset name, current parameters in use can be overwritten to the selected preset. Although each preset has an initial value, the user can rewrite all the presets freely.

    • Color Vision Type Selector

      A selector which specifies a color vision type of a user."P" means Protan, "D" means Deutan and "T" means Tritan. A color vision type can be also set in the "Settings" and "Find Color" Mode, and these are interlocking.

    • Color Change Two-dimentional Slider (Distinguish Color) (possible value: Variation (distance) 0.0〜0.5, Direction (angle) 0.0〜1.0)

      A two-dimensional slider which specifies how the color belonging to a color zone is changed. The color modification values when this slider is moved are different according to the color vision type. The slider is circular.
      There are two kinds of parameters for color changing. One is the "Variation (distance) (of a color change)", and the other is the "Direction (angle) (of a color change)." Both values are 0.0 when the thumb is located in the center of the circle.
      The "Variation (distance) (of a color change)" parameter is the distance between the center of the circle and the thumb when the diameter of the circle is 1.0, and the variation of color change becomes larger as the value is increased.
      The "Direction (angle) (of a color change)" parameter is calculated from the angle of the thumbs position in a clockwise rotation when the upper part of a circle is 0.0 and dividing it by 360 degrees (2 pi) and is normalized in the 0.0 to 1.0 section. For example, in the case of P and D types, it will change to white when the value is 0.0 (above), and yellowish when the value is 0.25 (right), dark when the value is 0.5 (below), and bluish when the value is 0.75 (left).
      "Boost mode" is changed to ON when this slider is double-tapped. (The slider background becomes a deep color and the color of the thumb-slider changes to golden.)


    "Find Color" Mode


      In this mode, the color approximated as the "Cursor Color" (color currently displayed on the cursor) is changed. This mode is used in order to find the similar color of the part of the displayed image or to find one of the basic colors set up beforehand.
      The word of "similar color" in this mode differs in nuance from how the term is generally used. For example, although bright yellow and dark yellow are not generally similar colors, they are regarded as similar colors in this application. This application judges whether a color is similar or not with chromaticity (sometimes called "tone" etc.), without taking into consideration the difference in brightness (bright or dark).
    • "Find Color" Toolbar

      Displays the "Left Pop-up Button", the "Searching Radius Slider" and the "Right Pop-up Button."

    • Basic 11 Colors Ribbon

      The domain which horizontally arranges the basic 11 colors used as the reference to find a color, and has a form like an oblong ribbon. Colors are displayed sequentially from the left Achromatic(N), Red(R), Yellow Red (YR), Yellow(Y), Green Yellow(GY), Green(G), Blue Green(BG), Blue(B), Purple Blue(PB), Purple(P) and Red Purple(RP), and selected form vivid colors in the JIS Generic Color Name standard.
      While this domain is displayed on the main screen, you can set the "Cursor Color" to the ribbon color by aligning the cursor position with a part of the ribbon for using as the searching color. When one of the color names is chosen from the "Basic 11 Colors Pop-up Menu", the cursor moves onto this ribbon automatically.

    • Left Pop-up Button

      Displays the "Basic 11 Colors Pop-up Menu."

    • Searching Radius Slider (possible value: 0.0〜1.0)

      Specifies the searching radius for how similar a color with a searching color (cursor color). If this value is small, only similar colors will be looked for, and if the value is large, also a color which is not so similar will also be looked for.
      The color judged to be similar is changed according to parameters set with the "Color Change Two-dimensional Slider." The calculation of a distance between colors uses u'v' chromaticity according to the distance on u'v' coordinates. The value 1.0 of a searching radius is equivalent to the value 0.1 in u'v' coordinates.

    • Right Pop-up Button

      Displays the "Color Vision Type Selector" and the "Color Change Two-dimensional Slider (Find Color)."

    • Basic 11 Colors Pop-up Menu

      A pop-up menu for selecting a basic color as a reference to find color. When one of the color names is chosen by tapping, the cursor moves onto the same color part of the "Basic 11 Colors Ribbon" automatically.

    • Color Vision Type Selector

      A selector which sets up the color vision type of a user. "P" means Protan, "D" means Deutan and "T" means Tritan. The color vision type can be also set in the "Settings" and "Distinguish Color" mode, and these are interlocking.

    • Color Change Two-dimensional Slider (Find Color) (possible value: Variation (distance) 0.0〜0.5, Direction (angle) 0.0〜1.0)

      A two-dimensional slider which sets up how similar colors are changed. The meaning and operation are the same as the "Color Change Two-dimensional Slider (Distinguish Color) in the "Distinguish Color" mode. However, the value is independent. The "Boost mode" does not exist in the "Find Color" mode."


    "Simulation" Mode


      Creates an image which persons of a specified color vision type are probably seeing from the original image source, and displays it.
      Although the simulated image is made with the same technology as the "Chromatic Vision Simulator", which is a sister application, it is not necessarily exact. Please use this simulation image as a rough indication of what the specified color vision type might be seeing.
    • Simulation Toolbar

      Displays the "Simulation Color Vision Type Selector" and the "Simulation Intensity Slider."

    • Simulation Color Vision Type Selector

      Sets up a color vision type of the color vision simulation performed in this mode and when the "Simulation Button" are turned ON. "C" means Common type, "P" means Protan type, "D" means Deutan type and "T" means Tritan type. The original image is displayed when "C" type is chosen.

    • Simulation Intensity Slider (possible value: 0.0〜1.0)

      Specifies an intensity of the color vision simulation performed in this mode and when the "Simulation Button" is turned ON.
      When the value is 0.0, the original image is displayed, but when the value is 1.0, a full simulated image is displayed. When the value is in between, an image of linear interpolation according to the value of the original and the simulation is created and displayed.


    Settings Screen

    • Color Vision Type
      Choose a color vision type used in "Distinguish Color" and "Find Color" mode from "Protan", "Deutan" and "Tritan."

    • Color Changing Option Settings
      Sets up various color changing options used in the "Distinguish Color" mode.

      • Auto Color Zone
        Moves the center of the color zone to a position of the "Cursor Color" automatically for making it easy to distinguish a "Cursor Color." When this is ON, the "Color Zone Range Slider" becomes yellow and it moves automatically. Please adjust the width of the color zone with the "Color Zone Range Slider" as usual.

      • Reverse Color Zone
        Reverses a color zone. For example, when the range of the "Color Zone Range Slider" is 0.3~0.5, then 0.0~0.3 and 0.5~1.0 they become color zones, and the color of the range is changed. This setting is effective to distinguish both sides of red and green at once (P, D type example).
        When it is ON, the "R" indicator appears at the end of the "Zone" in the "Status Information."

      • Inversion (of a color change) on Both Sides (of the zone coordinate)
        This setting is an optional feature for distinguishing the red and green side quickly in the case of P and D types, and green and blue sides quickly in the case of T types.
        The "Direction (angle) (of a color change)" of the "Color Change Two-dimensional Slider" is used as a 180 degree (pi) = 0.5 rotated value when a zone coordinate of the color is smaller than the achromatic (monochrome) position (the left-hand side of the "Color Change Two-dimensional Slider (Find Color)).
        On a chromaticity diagram, only the color which belongs to the green side from the line, that connected with yellow, white and blue, is changed with the "Direction (angle) (of a color change)" of 0.5 (blackish) when it is 0.0 (whitish), 0.75 (bluish) when it is 0.25 (yellowish).

      • Keep Achromatic Zone
        This switch makes neither white nor gray changes in a color, and keeps them from blinking. Correctly, the color, which has a short distance (less than +-0.05) from the achromatic on the zone coordinate, is not changed. Yellow and Blue in the case of P, D types and Red and Blue Green in the case of T types are also not changed.

      • Boost Mode
        This is the mode which makes the color change stronger than usual. Colors are changed sharply according to the "Variation (distance) (of a color change)" of the "Color Change Two-dimensional Slider (Distinguish Color)."
        When it is ON, the background color of the "Color Change Two-dimensional Slider (Distinguish Color)" turns into a deep color, and the color of the thumb-slider also changes from silver to gold, and the "B" indicator appears at the "Vary" in the "Status Information." This switch can be turned ON and OFF by double-tapping on the "Color Change Two-dimensional Slider (Distinguish Color)."
        The color changing algorithm in this mode is different from the one usually used. It does not use the method with the confusion line as usual, but uses the method which makes the color close to the color of the spectrum light 575 nm and 475 nm for P and D types, 575 nm and 475 nm for T types.

    Notes

    • This application software was developed by Kazunori Asada (Ph.D. of Medical Science and Ph.D. of Media design), and is released free. (patent pending)
    • The simulation algorithm which is used in this application is based on the proposed method of the following treatise, and reproduces the color in which a dichromat, which is the biggest grade of color vision deficiency in each type of color vision, is probably seen by high-speed operation artificially.
      H. Brettel, F.Viénot, and J. D. Mollon: Computerized simulation of color appearance for dichromats, Journal of the Optical Society of America A, vol.14, no.10, pp.2647-2655 (Oct. 1997).
    • The simulation image displayed in this application is made by prediction under how dichromats see the color under a specific technique and conditions, and is not necessarily exact. Moreover, each individual has different color vision.
    • The color value and name displayed in this application is computed by calculation based on several standards under the specific precondition, and is not necessarily exact. Moreover, there are variations in the characteristics of the screen and camera on the device to be used.
    • The color name searching algorithm currently used with this application, is developed in collaboration with Mr. Daisuke Nishioka who is a developer of the "Chromatic Color Helper."
    • "Color Vision Deficiency", "Protanope / Protanomal / Protan", "Deuteranope / Deuteranomal / Deutan" and "Tritanope / Tritanomal / Tritan" used in this manual are scientific terms.
