Description

[Brief explanation of drawings]

FIG. 1 is a diagram showing an embodiment of the present invention, and FIG. 2 is a configuration diagram of a conventional target detection device. In the figure, 1 is a fixed visible camera, 2 is an image processor, 3 is a recorder, 4 is a display, 5 is a memory 1,
6 is a memory 2, 7 is a memory trigger generator, and 8 is an image comparator. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] A fixed visible camera for imaging a target, an image processor that digitally processes the signal from the fixed visible camera using a contrast difference and outputs digital image pixel information, and a memory trigger that transfers the stored memory data to the memory 2. , at the same time, a memory 1 that newly stores image pixel information from the image processor, a memory 2 that stores memory data from the memory 1 by a memory trigger, and control of whether or not to store digital image pixel information in the memory 1. and a memory trigger generator that generates a memory trigger that controls the transfer of data from memory 1 to memory 2, and compares the digital image pixel information of memory 1 and memory 2, and if there is a difference between them, it is determined that there is a moving object. An image comparator that judges and transfers the digital image pixel information to a recorder, a recorder that records the digital image pixel information from the image comparator, and a display that monitors the digital image processed signal from the constantly fixed visible camera. A moving object detection device has a means for determining whether a moving object is a moving object by comparing pixel information subjected to digital image processing, and a function of recording digital image pixel information only when a moving object is present.
