Abstract: The present invention provides a monitoring image recording apparatus capable of searching image data stored in a hard drive at high speeds. In this invention, video signals input from cameras 10 are detected by motion detector 14, and the difference of search results is stored in a hard drive 18 as incidental information of image data. When playing, based on the incidental information of image data, it is determined whether or not a motion is present within a set range. If motion is present, image data stored in the hard drive 18 is output to a monitor television 23.

Abstract: Arbitrarily setting display patterns of live pictures or reproduced pictures per monitoring area in accordance with the purpose of use. Video signals 41 of the picture shot by monitoring cameras installed in a plurality of locations are digitized per monitoring area using the predetermined standard and recorded on video recording apparatus 8. The video signals 41 are displayed on a monitor (not shown) as live pictures. In this practice, the signals undergo the multi-screen processing via multi-screen reproduce/decoding control means 11 and displayed on screens split by monitoring camera in a monitoring area or by monitoring area.

Abstract: In an automatic focusing camera comprising optical object distance detecting means having a light emitting element for measuring an object distance and a light receiving element for receiving the reflected light from an object, provision being made of rotating means which rotates about an optical axis of a camera lens and which has scanning means cooperating with the light receiving element to detect the object distance as a function of an angular displacement of the rotating means.
