PURPOSE:To realize a high processing speed, a high function, and a high picture quality without requiring a massive picture memory. CONSTITUTION:Object light is converted to an electric signal by a CCD 110, and it passes a sample and hold (SH) circuit 111, an amplifier 114, and a clamping (CP) circuit 116 and is converted to digital data by an AD converter 118. A difference signal between adjacent picture elements is generated from the electric signal by a delay circuit 112 and a subtractor 113 and passes an amplifier 115 and a clasping (CP) circuit 117 and is converted to digital data by an AD converter 119 and is subjected to picture processing by a DSP 120. |
