This function, "Tilted Angle Correction" (Reverse Projection Transformation), revises such distortion as if you saw it from directly overhead. You can change the "Degree of Tilted Angle Correction" parameter by pinching the bottom of the screen or by using the "Degree of Tilted Angle Correction' slider in the Settings screen.

Settings Screen

You can change various settings in the Settings Screen.
  • Monochrome Mode
    • Discard Color Information
      Discards Chromaticity Information and only uses Lightness information. Readability for an individual who cannot read easily due to eye illness, etc. may improve with this setup. (default value: OFF)
    • Color(s) Used
      Specifies the color(s) used for the "Monochrome" (or "Duochrome") mode. The specified color or combination of colors (chromaticity information only) is used.
      For example, in the case that one color is specified (Monochrome), such as "Light Blue", colors which have the same chromaticity as "Light Blue" are displayed. In the case that two colors are specified (Duochrome), such as "Yellow and Blue", a color which has the same chromaticity as Yellow is displayed when the Lightness value is at its highest, and a color which has same chromaticity as Blue is displayed when the Lightness value is at its lowest (dark). A color's chromaticity is determined by the linear interpolation between light and dark according to its own Lightness.
      In addition, "Color(s) Used" can be shifted to the next color(s) by tapping the screen with 2 fingers when the "Shift by double-tapping w/ 2 fingers" is ON. (default: Achromatic)
    • Custom Color
      Specifies the color used for the "Custom (Monochrome)" mode (only chromaticity is used). (default value: Yellowish Green (R 66%, G 100%, B 0%))
    • Custom Color (Light)
      Specifies the Light Color used for the "Custom (Duochrome)" mode (only chromaticity is used). (default value: Yellow (R 100%, G 100%, B 0%))
    • Custom Color (Dark)
      Specifies the Dark Color used for the "Custom (Duochrome)" mode (only chromaticity is used). (Choose "White Color" when you would like to use Achromatic.) (default value: Purple (R 50%, G 0%, B 100%))

  • Degree of Tilted Angle Correction
    Adjust the degree of correction for the "Tilted Angle Correction". This parameter is used when the "Tilted Angle Correction" is ON. The effect is weaker when the slider is moved left, and stronger when the slider is moved right. The "Degree of Tilted Angle Correction" can also be adjusted by pinching an area at the bottom of the screen with 2 fingers, when "Tilted Angle Correction" is ON. (Possible range: Trapezoid (lower base)/(raised bottom) = 0.2-1.0) (default value: 0.5)
