Image processing apparatus and mobile terminal apparatus

A mobile terminal device comprising:

• an input portion to which video signals are inputted;
• a detector which detects a change of the video signals in accordance with a mean value of luminance of the video signals inputted to the input portion;
• a corrector which corrects the video signals inputted to the input portion;
• and
• a controller which executes control so that the corrector corrects 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.

An image processing apparatus comprising:

• an input portion to which video signals are inputted;
• an illumination sensor for detecting illumination;
• a correction portion for correcting the video signals inputted to the input portion;
• and
• a control portion for executing 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 illumination detected by the illumination sensor when a characteristic point of the video signal inputted to the input portion changes.
