Stehbildübertragungssystem

摘要

Image data of four frames in total are stored in four memories and the image data from the four memories are sequentially transmitted, whereby still picture image data having a resolution twice the resolution of a CIF (common intermediate format) image based on a video CODEC recommendation H.261 can be transmitted. In the still picture transmission conforming to the video recommendation H.261, frames four times the transmission frame are prepared and first to fourth frames are stored in first to fourth frame memories (27a to 27d), thereby obtaining a still picture having pixels the number of which is four times the number of pixels of a CIF still picture based on the video CODEC recommendation H.261.
