ABSTRACT:
The invention provides an image signal processing apparatus, an image signal processing program and an image signal recording medium, each capable of generating high-definition image signals with no or little artifacts. The image signal processing apparatus adapted to implement tone correction of an image signal comprises correction coefficient calculation block (112) for calculating a correction coefficient for a pixel of interest in that image signal and a neighborhood area, transformation block (110) for applying tone correction processing to that pixel of interest, and correction block (111) for using that correction coefficient to make correction of each pixel after that tone correction processing. An image signal of each pixel of interest from correction block (111) is forwarded to compression block (113), and at a time when all image signals are in order, compression processing such as known JPEG is applied to them for their forwarding to output block (114).
