Fundamental performance and key technologies of image sensors featured for digital still cameras' operation are picked up and described in the report. It focused into the technologies how image sensors overcame year by year increasing resolution and functions for compact digital still cameras, which are not required current video cameras. CMOS image sensors' characteristics are also described in contrast to CCD image sensors, because these become to be widely used in digital single lens reflex

... ameras and cellular phones more than before. It discusses mainly about monitor mode and motion picture operation as necessary functions in digital still cameras, sensitivity and signal-to-noise ratio as basic characteristics, operation of image sensors and coordination of image sensors to camera lens.
