Single board color camera

Abstract

Abstract PURPOSE:To improve resolution by extracting a chrominance signal and a luminance signal with the specified arrangement of a mosaic color filter and sequential frequency separation and to decrease power consumption by preventing the fog of a screen at a dynamic picture photographing. CONSTITUTION:A solid-state photographing element 2 is arranged on an image forming face of a lens 1 of a single board color camera and a mosaic color filter 3 is provided on the surface of the solid-state image pickup element 2. Further, the mosaic color filter 3 is arranged as the repetition of white, cyan, white, yellow in the column direction and arranged further with the repetition of green, yellow, green, cyan in the 2nd column. Further, the scanning line is combined at the same time in the unit of 2 rows and read sequentially. Further, a frequency-modulated signal is extracted from a signal applied via a sample- and-hold circuit 7 to a BPF8, after the signal is delayed at a delay circuit 9, the result is detected by a detecting circuit 11 and chrominance signals R, B are outputted from a switch circuit 12.
