Abstract:
1. A display apparatus comprising: a light modulating section which modulates illumination light according to a light modulation coefficient and displays an image on a screen; a radiating section which radiates the illumination light on the light modulating section with an illumination light amount which varies per light emitting area of the screen; a control section that receives a video signal and which controls light emission brightness of the radiating section per light emitting area based on a control signal output by the control section; a video correcting section which corrects the video signal based on a light amount of illumination light which arrives at the light modulating section; a converting section separate from the control section and that receives the video signal and which applies individual gradation conversion processing on each pixel of the video signal and acquires a converted brightness value per pixel; and a first driving section which controls the light modulation coefficient per pixel based on the acquired converted brightness value, the control signal output by the control section is not input into the converting section, wherein for each processing target pixel in the video signal, the converting section sets conversion characteristics of decreasing a brightness value of each processing target pixel when a luminosity in a surrounding area of each processing target pixel is higher, the surrounding area being a part of area in the video signal, and performs gradation conversion using the set conversion characteristics.
