Abstract

The invention discloses a method for upgrading a video camera. The method upgrades the video camera by using a transmission upgrade packet of a reverse blanking zone, prevents disassembly, and achieves simple operation and low upgrade cost. After receiving a upgrading instruction sent from a rear end and switches a normal operating mode to a upgrading mode but before transmitting a response signal to the rear end, a front-end video camera sets an initial valid data zone and an initial reverse blanking zone in the normal operating mode as reverse blanking zones, namely increases the number of rows of the reverse blanking zone. Thus, when receiving the upgrading packet sent from the rear end via the reset reverse blanking zone, the front-end video camera may increase the transmission capability and speed of the reverse blanking zone so as to increase the upgrading speed of the video camera. Additionally, after upgrading is completed, the front-end video camera restores the initial valid data zone and the initial reverse blanking zone in order not to influence the normal operation of the front-end video camera after the upgrading.

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...
