Display apparatus, method and program

摘要

A display apparatus that displays a composite image of a front image and a back image. The display apparatus includes: a front-image change detecting unit 42 that detects a difference in a visual characteristic between a sub-pixel and the surrounding sub-pixels in a front image; a filtering necessity judging unit 43 that judges for each sub-pixel in the front image whether a sub-pixel should be subject to the filtering process or not, based on the degree of the detected difference; and a filtering unit 45 that performs the filtering process only on sub-pixels in the composite image that correspond to the sub-pixels that have been judged as having to be subject to the filtering process.
