ABSTRACT:
An image processing apparatus and an image processing method permit easy adjustment of luminance and contrast, and also permit easy check of the brightness of a target image. A signal format of an image signal is determined by a determiner circuit, and an image signal of a luminance reference image that provides the standard for determining luminance is generated by a luminance reference signal generator circuit on the basis of a result of the determination. A mixing circuit generates an image signal for displaying a target image combined with a luminance reference image. The signal level of the image signal is adjusted by an adjusting circuit so as to adjust luminance and/or contrast. A discrimination display signal superimposing circuit generates a signal of a luminance identifying image superimposed in a desired luminance area. From the luminance reference image, the brightness at a desired position on an image can be easily checked.
