PROBLEM TO BE SOLVED: To display a fogged image that a contour of an image is gradually suppressed with the lapse of time and to execute smoothly fader image processing that expresses depth perception by a video camera or the like. SOLUTION: The processing unit is provided with a luminance signal processing circuit 13 that adjusts a frequency component of a luminance signal Yin of an optional image, an operation switch 16 that instructs a fader image processing mode where a signal level of an image luminance signal Yin is gradually changed or a processing mode of a usual image, and a control microcomputer 15 that controls the luminance signal control circuit 13 based on an instruction of the processing mode by the operation switch 16, and the control microcomputer 15 controls the luminance signal processing circuit 13 so as to bias a frequency component of the luminance signal Yin toward a lower frequency in the case that the operation switch 16 instructs the processing mode of the fader image and controls the luminance signal processing circuit 13 so as to extend a frequency component of the luminance signal Yin toward a higher frequency in the case that the operation switch 16 instructs the processing mode of the conventional image. |
