Circuit apparatus and display system

A circuit apparatus that controls a display apparatus including a backlight and an electro-optical panel, the circuit apparatus comprising:

• a color information extraction section that extracts color information from image information;
• a luminance information extraction section that extracts luminance information for controlling luminance of the backlight based on the color information;
• a dithering section that adds bits for dithering to a lower bit side of the luminance information and outputs the luminance information after the addition to the display apparatus as output luminance information;
• an image color correction section that corrects a color of the image information and outputs the corrected image information as output image information to the display apparatus;
• and
• an upper bit comparison section that compares upper bits of the luminance information, upper bits of the output luminance information, and upper bits of the output image information with each other.
