Abstract
An image pick-up device including an image taking optical system, an image pick-up element for photoelectric conversion of an object image to be projected by the image taking optical system, a system conversion circuit for outputting the image pick-up signals output from the image pick-up element as video signals in accordance with a predetermined signal standard, and a focussing control circuit for controlling focussing adjustment of the image taking optical system by using the image pick-up signal before input to the system conversion circuit.
Claims27
An image pickup device usable with a recording means, comprising:
- an optical system that forms an optical image of an object to be projected;
- photoelectric conversion means for converting the optical image formed by said optical system into a video signal and outputting the video signal to the recording means, said photoelectric conversion means converting the optical image into a video image having a first signal format;
- conversion means for converting the video signal output from said photoelectric conversion means into a video signal having a second signal format different from the first signal format, the video signal of the second signal format converted by said conversion means being output to the recording means in parallel with the video signal of the first signal format output from said photoelectric conversion means;
- and
- adjustment means for adjusting said optical system based on the video signal of the first signal format output to the recording means in parallel with the video signal of the second signal format.
