A multimedia data recording apparatus is disclosed that enables large-volume recorded data to be recorded for a long period in accordance with the importance of the data, by means of a simple configuration and simple processing, and without imposing a heavy load on the system. In this apparatus, a layer classification section classifies video data captured by a surveillance camera and input via a video processing section into a plurality of layers on a frame-by-frame basis according to importance. A data recording section assigns a file to each layer and records classified data in a data recording medium. If an information amount reduction section detects that the vacant capacity of the data recording medium has reached or fallen below a threshold value, it deletes a frame belonging to the lowest layer among the plurality of layers.

PROBLEM TO BE SOLVED: To eliminate the need of a human body sensor and to reduce the recording having the low value of use by detecting whether a man is displayed on an input picture or not and recording the input picture only when the detected man is judged to be displayed. SOLUTION: A man detection means 13 detects whether the man is displayed or not by using the input picture taken by a television camera or the like. Only when the man is judged to be displayed, it is inputted to the sub-sampling means 21 of the man detection means 13 and a picture signal outputted from the sub-sampling means 21 is inputted to a background picture update/storage means 22 and a subtracter 23. The picture signal from the background picture update/storage means 22 is inputted to the substrater 23. The output signal of the substrate 23 is inputted to a comparator 27 through an absolute value computing element 24, a binarization means 25 and an area operation means 26. Then, it is outputted to a recording device 14 from the comparator 27 and the picture is recorded.

Monitoring picture recording device

A monitoring system excellent in creation, compression, decompression, and recording of image data, and system management compared to conventional one. To create image data, data deemed to be less important is thinned by executing a capturing command and by adjusting the compressibility of the codec, a differential coefficient measuring circuit and a lowpass filter is used for compression/decompression, a fixed disk and a removal disk are used together to avoid data loss due to exchange, and the system parameters and control program are automatically set and altered.

PROBLEM TO BE SOLVED: To surely record an image signal before and after alarm input in the monitoring image recording and reproducing device in which an image signal from a camera is recorded onto a recording medium and the signal is reproduced from the recording medium. SOLUTION: An image signal from a camera 1a is overwritten continuously to a pre-recording memory 28. When an alarm is received from a sensor approaching the camera 1a, the image signals from the camera 1a over a prescribed time after the alarm input are stored in a recording memory 27 and the image signals just before alarm input are read from the recording memory 28 and stored in the recording memory 27. Then the image signals before and after the alarm input are surely stored in the recording memory 27.
