Image processing method of camera for supervision and camera for supervision

摘要

(57) Abstract The camera for supervision of this invention the image signal reception section, the image signal decoder, the image signal compressor and the retention device, includes the control section. The image signal reception section receives the input of image, converts to the electric image signal and outputs, converting the electric image signal which the image signal reception section outputs to the digital signal, outputs the image signal decoder, compressing the output digital signal of the image signal decoder, outputs the image signal compressor, the retention device retains the compressed digital image signal which was compressed with the image signal compressor, the control section, controls the conversion and compression and retention operation of the image signal. According to the image processing method of the camera for supervision of this invention and the camera for supervision, it is possible to offer the image processing method of the camera for supervision and the camera for supervision which can retain the image signal inside the camera itself. In addition, it is possible to offer the image processing method of the camera for supervision and the camera for supervision where safety and preservation characteristic improve by it tries to being able to retain the image signal in the camera itself for supervision, vis-a-vis the damage of the monitoring system.
