    摘要: The present invention relates to an endoscopic apparatus which creates image information based on picture signals from an electron endoscope and has a memory device for storing the image information. The endoscopic apparatus is provided with a driver for driving a solid-state image pickup device in the endoscope, a picture signal generation circuit for generating a picture signal based on an image pickup signal which is photoelectrically converted by the solid-state image pickup device, an A/D conversion circuit for converting the picture signal from analog to digital, a process circuit for creating image information to be transferred to a memory capable of storing image information for one frame, based on the picture signal by digital processing, such as interpolation, a small capacity memory capable of storing image information for a plurality of frames and composed of, for example, a semiconductor, a CPU for controlling writing/reading between the memory and the small capacity memory, and a D/A conversion circuit for converting the image information from digital to analog so as to generate a video picture signal.
