Camera shooting device anti-flicker method and system, camera shooting device and control method of camera shooting device

Abstract

The invention discloses a camera shooting device anti-flicker method and system, a camera shooting device and a control method of the camera shooting device. The method comprises the steps that a corresponding relation table between country codes and the working frequency of an intelligent lamp is stored in the camera shooting device; AE exposure tables of the camera shooting device under different intelligent lamp working frequencies are stored in the camera shooting device; the intelligent lamp communicates with the camera shooting device in a wireless communication mode and sends a countrycode of the intelligent lamp to the camera shooting device; and the camera shooting device acquires the working frequency of the intelligent lamp according to the received country code of the intelligent lamp, and sets an AE exposure table of the camera shooting device according to the working frequency of the intelligent lamp so as to adapt to the frequency of the intelligent lamp. According to the camera shooting device anti-flicker method and system, the camera shooting device and the control method of the camera shooting device, the flicker problem of the camera shooting device in different countries under different light sources can be solved, the flicker phenomenon of the camera shooting device can be solved in a self-adaptive mode, and meanwhile the power consumption of the camera shooting device can be reduced.

Description

technical field [0001] The invention belongs to the technical field of camera control, and relates to a camera, in particular to an anti-flicker method and system for a camera, and a control method for the camera. Background technique [0002] Surveillance and smart lights are devices that are very common in household devices today. As we all know, general consumer CMOS sensor exposure is rolling shutter (rolling shutter), this form of exposure needs to do different exposure special treatment for the light source of lamps in different countries. For example, lights in some European and American countries have a 60hz light source, while lights in mainland China use a 50hz light source. At this time, the camera equipment needs to do a special algorithm for the light to detect whether it is 50hz or 60hz. If it is not handled properly, the screen will flicker ( Flicker) phenomenon. [0003] When a 60hz light source is detected, a set of 60hz automatic exposure meters will be s...

Problems solved by technology

This processing is detected by a software algorithm, which requires the camera device to detect the current light source at regular intervals. This solution sometimes not only has misjudgment, but also can only be detected within a period of time after the camera is started. In addition, it needs to be detected at intervals Time to do a detection, which brings the computing power consumption of the camera equipment

[0004] In addition, some manufacturers choose to customize the 50hz or 60hz automatic exposure meter of the camera equipment according to the seller's national light source when the factory ships, but this needs to know the frequency of the target market's national light in advance

This method fixes one of the exposure meters by locating the target customer’s country. This method is not so flexible. When the light used by the customer is different from the one customized by the factory, then the camera equipment will definitely have flicker phenomenon at this time.
