Endoscopic apparatus capable of storing image information for a plurality of frames
First Claim
1. An endoscopic apparatus, comprising:
- image pickup means for picking up an optical image obtained by an imaging optical system in an endoscope;
illumination means including a light source for supplying illumination light to said endoscope; and
control means for controlling an image pickup signal output from said image pickup means, said control means including an analog-to-digital converter for converting said image pickup signal into digital image information,wherein said control means further including memory means for digitally storing said digital image information for a plurality of images consisting of continuous multiple frames of said digital image information recorded in a predetermined time interval; and
wherein said memory means includes a plurality of detachable memory-type adaptor devices, each said memory-type adaptor device being insertable into a single common receptacle in said control means, said memory-type adaptor devices being adapted to house memory devices having different formats, respectively.

Abstract
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.
