Abstract

PURPOSE:To improve the vertical resolution of a single-plate color solid-state pickup unit by using mosaic color filters, by using a green signal of a narrow band for vertical processing. CONSTITUTION:A signal, corresponding to a picture element sensitive to green light, is extracted from the output of solid-state pickup element 11 combined with mosaic color filters and then supplied to sample holding circuit 17 to separate a green signal of a narrow band. Simlarly, red and blue signals of narrow bands are held by sample holding circuit 20; one is supplied to switching unit 22b via 1H delay line 21 and the red and blue signals of narrow bands are led out of switching units 22a and 22b. Those signals are applied to process amplifiers 19, 24 and 26 by way of LPF18, 23 and 25. In this case, the vertical resolution depends upon three primary color low-frequency components. Therefore, the input signal of each holding circuit is only the output signal of pickup element 11, so that the vertical resolution can greatly be improved.
