Abstract
A flicker detection device includes an accumulation section that divides a screen into a plurality of areas to perform accumulation of pixel levels, writing and reading of the accumulation result to and from a memory area allocated to every area, thereby accumulating the pixel levels in the area for every area, an accumulation result memory that stores the accumulation results of the accumulation section, an area discrimination section that discriminates whether or not every area is a still image area using the accumulation result obtained by the accumulation section and the accumulation result stored in the accumulation result memory, and a flicker level calculation section that averages the accumulation results of the areas discriminated as the still image area by the area discrimination section, and performs an operation using the averaged accumulation result and the accumulation result obtained by the accumulation section, thereby calculating a flicker level.
