Abstract :
A newly developed compact camera which can take digital still pictures by using a semiconductor IC memory card is described. The developed prototype is suitable for consumer use because of its easy operation and fully automatic functions. High-quality frame images are obtained with degradation-free data compression LSIs. The camera makes it possible to store 13 high-quality still pictures in a 20-Mb SRAM card by using a frame imaging frame interline transfer CCD and a data compression technique for ADPCM (adaptive differential pulse-code modulation)
