PURPOSE:To attain miniaturization and to reduce the cost by using a storage means having a memory area for one line to apply processing such as stereoscopic shading. CONSTITUTION:A picture data read by a CCD line image sensor 40 is amplified by an amplifier 41 and converted into a digital data from an analog data by an A/D converter 42 and the converted signal is fed to a picture processing section 43. A one-line memory is used to subtract a prescribed value from a digital picture data by one line and fed to the digital picture data by one line given newly. When a prescribed value to be subtracted is varied, a shade data is changed. Since the storage means having the memory area by one line is used for the processing in this way, the small sized and inexpensive picture forming device is obtained. |
