摘要： When a video input (image data) sequentially fetched from a monitor camera is to be stored in data storage means, frame rate calculating means calculates a frame rate for storage of the image data by using a picture recording time mode, a residual capacity of the data storage means, the presence of generation of an alarm signal and a value of a picture quality parameter for data compression. The frame rate calculating means thins a video signal which does not correspond to the frame rate so as not to be stored in the data storage means. Consequently, image data for a predetermined time are stored in the data storage means.

摘要： An image recording and reproducing apparatus for recording and reproducing a multiple picture signal obtained by multiplexing picture signals from a plurality of cameras via a frame switcher, the image recording and reproducing apparatus performing high-accuracy fast-forwarding of a prerecorded image from a specific camera and allowing easy retrieval of a target image. The image recording and reproducing apparatus has a skip reproduction feature for alternating skipping of n frames and continuous reproduction of m frames. m is set to a number related to the frame switching pattern. In case n=4 and m=3, four frames are skipped after reproduction of Frame A1. Then Frames C6, A7, B8 are continuously reproduced. Thus, the images displayed on the monitor are A1, A7, and A13.
