Abstract
An apparatus according to the present invention includes an acquisition unit configured to acquire an input image, a conversion unit configured to convert the acquired input image to an output image, a detection unit configured to detect in the input image a pixel having a predetermined luminance, a calculation unit configured to calculate a position of an output image corresponding to a position of the detected pixel, and a display unit configured to display the output image on a screen.
Claims14
An apparatus comprising:
- an acquisition unit configured to acquire an input image;
- a conversion unit configured to convert the acquired input image to an output image of lower bit depth;
- a detection unit configured to detect in the input image a pixel having a predetermined luminance;
- a comparison unit configured to compare a gradation of the input image with a gradation of the output image;
- a calculation unit configured to calculate a position of the output image corresponding to a position of the detected pixel in the input image, if the gradation of the input image is greater than the gradation of the output image;
- and
- a display unit configured to display the output image on a screen so that the calculated position is identifiable,
- wherein the detection unit further detects a pixel having a predetermined luminance in the output image, and
- wherein the display unit further displays a position of the pixel having the predetermined luminance in the output image to be identifiable from the calculated position.
