ABSTRACT:
An image pickup apparatus including: an image pickup device; a mode selection circuit for selecting a mode from a group consisting of a video camera mode and a still video camera mode; a first drive circuit for, when the video camera mode is selected by the mode selection circuit, driving the image pickup device to perform an interlace-scanning operation so as to read vertically-disposed two pixels while being mixed with each other; a second drive circuit for, when the still video camera mode is selected by the mode selection circuit, driving the image pickup device to perform an interlace-scanning operation so as to read each row; a memory for recording a first field signal and a second field signal of the image pickup device at the time of the operation performed by the second drive circuit; an addition circuit for adding the first field signal of the memory and the second field signal of the same to each other; and a signal processing circuit for performing a signal process so as to generate a luminance signal and a chrominance signal in such a manner that it receives the output from the image pickup device when the video camera mode is selected by the mode selection circuit and receives the output from the addition circuit when the still video camera mode is selected by the same.
