Abstract: A video signal generating apparatus where the video signal is produced using two different image sensors has been described. The optical beam received from the camera lens is split into two beams via a beam splitter. Each beam is applied to the corresponding color and monochrome image sensors. Both imagers are scanned synchronously, and the corresponding output signals are digitized. The monochrome imager is scanned at a lower frame rate and generates a high-resolution luminance signal YH. The second imager has color filters, arranged as vertical stripes. This imager is scanned at a higher frame rate, faster than the first frame rate, and generates a set of two low-resolution color difference signals CR and CB, and one low-resolution luminance signals YL. At frame 1 both image sensors are scanned, at frames 2 and 3 only the color sensor is scanned, at frame 4 both image sensors are scanned, at frames 5 and 6 only the color sensor is scanned, at frame 7 both image sensors are scanned, and so on.
