DISPLAY CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a display controller for reflecting a visual environment of a viewer so as to control a luminance of a display.

SOLUTION: The display controller 1 includes: a photographed image conversion means 501 for converting a marker added photographed image into a marker added luminance image in which the luminance is given to each pixel based on a previously set function for converting a gradation value to the luminance; a video area luminance image generation means 502 for cutting out a video area from the maker added luminance image based on a position of the marker included in the marker added luminance image so as to generate a video area luminance image; a set luminance calculation means 503 for calculating an average luminance of the video area luminance image so as to calculate a set luminance from the calculated average luminance based on a correspondence relation between the set luminance of the display and the previously set average luminance; and a luminance control means 504 for controlling the luminance of the display.
