Zusammenfassung:A video signal recording apparatus having: an image pickup sensor having a plurality of pixels two-dimensionally disposed by a predetermined interval in horizontal and vertical directions, pixels being shifted alternately for each horizontal line; a recording circuit for recording a signal read by the image pickup sensor on a recording medium; a switch member for instructing which one of a moving image and a still image is to be generated; and a control circuit for controlling generation of one of the moving image and the still image in accordance with an instruction by the switch member, wherein upon an instruction of the moving image, pixel signals on two adjacent horizontal lines of the image pickup sensor are read in a zigzag manner as first field signals, and pixel signals on two adjacent horizontal lines shifted in the vertical direction from the first-mentioned two adjacent horizontal lines are read in the zigzag manner as second field signals, the first and second field signals being recorded on the recording medium, and wherein upon an instruction of the still image, the first field signals are read and recorded in the recording medium and temporarily stored in a memory, and after reading the first field signals, the first field signals stored in the memory are read as the second field signals and read and recorded in the recording medium.
