Abstract:
1. A display apparatus adapted to generate image data for controlling a first light modulation section adapted to project a first window, and image data for controlling a second light modulation section adapted to project a second window smaller than the first window and projected so as to overlap with the first window, comprising: a first image conversion section adapted to convert a resolution of input image data in accordance a resolution of the first light modulation section to form the image data for controlling the first light modulation section; a second image conversion section adapted to extract data included in a range corresponding to a resolution of the second light modulation section among the input image data to form the image data for controlling the second light modulation section; an observation distance measurement section adapted to measure an observation distance from a projection screen of the first and second windows to an observer; a window size parameter generation section adapted to generate a window size parameter for designating a size of the second window; an image quality setting section adapted to set an image quality control parameter for controlling image quality and brightness of the second window based on the window size parameter and the observation distance; and an image quality control section adapted to execute an image quality control process on the image data for controlling the second light modulation section obtained from the second resolution conversion section in accordance with the image quality control parameter, such that the brightness of the second window varies according to the window size parameter and the observation distance.
