ABSTRACT:
Auto focus control and/or auto exposure control is carried out by using a luminance signal before gamma correction, before addition of aperture signal but after hand shake correction. Auto white balance control is carried out by using a color signal after hand shake correction. Consequently, precise auto focus control, auto exposure control and/or auto white balance control can be done. The field memory for electronic zooming and/or hand shake correction is also used as a field memory for noise reduction. Consequently, a video signal processing circuit which is inexpensive and simple can be implemented.
