Image processing apparatus and mobile terminal apparatus
View Patent ↗An image processing apparatus has an input portion for receiving video signals, an illumination sensor for detecting illumination of an environmental light, a corrector for correcting the video signals, and a controller for controlling the corrector to correct the video signals in accordance with distribution of luminance or hue or saturation of the video signals and with the detected illumination when any change occurs in the video signal. The apparatus further has a detector for detecting a change of the video signals in accordance with a mean value of luminance of the inputted video signals, a corrector for correcting the video signals, and a controller for controlling the correction portion to correct the video signals in accordance with distribution of luminance or hue or saturation of the video signals when the detector detects the change of the video signals.
1. An image processing apparatus comprising:
an input portion to which video signals are inputted;
an illumination sensor for detecting illumination;
a corrector which corrects the video signals inputted to the input portion; and
a controller which executes control so that the correction portion corrects the video signals in accordance with distribution of luminance or hue or saturation of the video signals and with the illumination detected by the illumination sensor when any change occurs in the video signal inputted to the input portion,
wherein the controller corrects luminance of the video signal without correcting hue and saturation of the video signal when the change of the video signal does not occur and when the illumination detected by the illumination sensor is above a predetermined value.
2. An image processing apparatus according to claim 1 , wherein the corrector executes correction in such a fashion as to increase an illumination tone on black side of the video signal.
