Electronic still camera

Abstract

Abstract PURPOSE:To obtain a small-sized electronic still camera with low power consumption and to reduce storage capacity per frame by preparing the same number of coding compressing means as the kinds of colors for color filters in each scanning to encode color separations and store the codes directly. CONSTITUTION:The output of a single-board color solid-state image pickup element 18 obtained by overlapping the color filters 19 is an output waveform repeating two colors, R and G or B and G, alternately in each scanning line. An A/D converter 27 converts the output of the element 18 into a digital signal of 8 bits in each picture element. The digital output is applied to two DPCMs 28, 29, coding compressing means, and outputted as compressed 4-bit DPCM coding signals and a G signal and an R or B signal are accumulated in RAM buffer memories 30, 31 in each picture element. The one-picture elements temporally stored in the buffer memories are immediately transferred to a magnetic bubble cassette 33 through a magnetic bubble interface 32 together with prescribed adding information.
