Image recording and reproducing system

Abstract

PURPOSE: To reduce the amount of image data to be recorded by recording significant image data and the image data that is not significant in ordinary recording by changing the compressibility and/or recording interval time of the data. CONSTITUTION: Since the image data when neither two passive sensors 2-1, 2-2 are operated i.e., no person is present is not significant, long interval time of intermittent recording is permitted, and also, no high definition image data is required, and it is enough to recognize a global summary. Thence, when only the passive sensor 2-1 with wide detecting range is operated, the high definition image data can be generated and also, control to shorten the recording interval time can be performed by decreasing the compressibility of the image data by a data compressor(encoder) and using data of about four times that when no person is present.
