Abstract
A display apparatus includes: an acquiring unit configured to acquire characteristic information on a correspondence relationship between a gradation value and image brightness of input image data; a converting unit configured to generate display image data by converting gradation values of the input image data based on the characteristic information and a predetermined correspondence relationship between a gradation value of the display image data and display brightness; and a displaying unit configured to display an image based on the display image data, wherein the converting unit converts the gradation values so that a linear characteristic is implemented in a first range, and a non-linear characteristic is implemented in a second range.
