Abstract

An electronic device (1) of the present invention includes as optical sensor (5) and a display section (2). The electronic device (1) further includes: an optical characteristic detection section (3) for detecting, on the basis of an output of the optical sensor (5), a characteristic of light incident on a display region which corresponds to the optical sensor (5); and a color saturation adjustment section (4) for adjusting, on the basis of the characteristic thus detected, a color saturation of display information which is to be displayed in the display region.

Description

technical field [0001] The present invention relates to an electronic device for implementing color correction on a color video signal, a chroma adjustment method, a program and a recording medium. Background technique [0002] In an electronic device such as a display device that displays a color image, there is known a technique of performing color correction on a color video signal to make the original color video signal appear more vivid. As this technology, there are Y (yellow), M (magenta) and C (cyan (also known as cyan) based on the addition of the three primary colors R (red), G (green) and B (blue) as their complementary colors. A technique for color-correcting signal components of six colors obtained for cyan or cyan)) is disclosed in Patent Document 1, for example. [0003] In the color display device disclosed in Patent Document 1, when correcting the chroma or brightness of a video signal, processing is performed so as not to exceed the upper limit. That is, ...
