Abstract

The invention discloses a method for upgrading a camera, which uses a reverse blanking zone to transmit an upgrade package to upgrade the camera without dismantling, simple operation, and low upgrade cost; moreover, the front-end camera receives an upgrade instruction sent by the back-end , after the front-end camera switches the normal working mode to the upgrade mode, before the front-end camera sends a response signal to the back-end, the front-end camera will set the initial valid data area and the initial reverse blanking area when it is in the normal working mode to reverse Blanking area, that is, increasing the number of lines in the reverse blanking area, so that when the front-end camera receives the upgrade package sent by the rear end through the reset reverse blanking area, the transmission capacity of the reverse blanking area can be improved and transmission speed, so that the upgrade speed of the camera can be improved; in addition, after the upgrade is completed, the front-end camera restores the initial effective data area and the initial reverse blanking area, which will not affect the normal work of the front-end camera after the upgrade.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a method for upgrading a camera. Background technique [0002] Existing cameras such as figure 1 As shown, it generally includes a sensor, a video signal processing module, a controller, and a memory; wherein, the sensor performs photoelectric conversion and signal acquisition on the target object; the video signal processing module performs digital image signal processing, digital-to-analog conversion and The processed video signal is transmitted to the back-end device through the video interface and coaxial cable; the controller can configure the parameters of the sensor signal acquisition and control the switch of the infrared lamp, IR-CUT (double filter) by loading the software in the memory. Light sheet switcher) switching and other functions. With the continuous expansion of the functions of the camera, the original system will gradually lose its timeliness, a...
