Image displaying method and image displaying apparatus

摘要

An image displaying apparatus divides 1 frame into plural sub-frame periods, and modifies the image signals in which a region denoted by an image signal α or an image signal close to the image signal α and a region of another image signal β or an image signal close to the image signal β are adjacent to each other. The image displaying apparatus carries out display, in at least one sub-frames period A, with a modified image signal so that the difference with the image signal of the other region becomes smaller, and in at least one other sub-frames period B, with a modified image signal so that the difference with the image signal of the other region becomes more significant, in the vicinity of the boundary between the region of the image signal α and the region of the image signal β.

主权项

1. An image displaying apparatus for displaying an image corresponding to an input image signal, the image displaying apparatus comprising:
a display control section to divide one frame into plural sub-frame periods including at least one sub-frame period A and at least one sub-frame period B, and to modify an image signal level of an input image signal of a target pixel such that an image signal level of the target pixel always has an image signal level greater than or equal to the image signal level of the image signal supplied in the at least one sub-frame period A or B and always has an image signal level less than or equal to the image signal level of the image signal supplied in the other one of the at least one sub-frame period A or B, wherein, in the sub-frame period A or B, a difference between an image signal level of the target pixel and an image signal level in a reference range of pixels in the vicinity of the target pixel, is either increased or decreased, and in the other of sub-frame period A or B, the difference between the image signal level of the target pixel and the image signal level in the reference range is the other of increased or decreased.
