Camera and method for switching color mode of camera

Abstract

The invention relates to the field of video monitor and discloses a camera and a method for switching a color mode of a camera. The method comprises the following steps: detecting whether an optical filter set is transmitted to a preset position detection point when a stepping motor is used for transmitting the optical filter set; controlling the stepping motor to move for preset steps at a preset speed when the optical filter set is transmitted to the preset position detection point; and then stopping the running of the stepping motor, switching the optical filter set at the current positionand switching the color mode of the camera into the required color mode. The operation of transmitting the optical filter set to a switching position point is precisely controlled, thereby realizing the accurate switching of the optical filter set and ensuring that the switched optical filter set can be accurately positioned in front of the camera in order to filter the light.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a camera color mode switching technology in the field of video monitoring. Background technique [0002] In order to achieve a better video shooting effect, the camera shoots in color mode during the day and in black and white mode at night. The camera judges the working environment and automatically switches the color mode. The conversion of the color mode is realized by switching the filter. Specifically, the camera contains: [0003] The filter set provides multiple sets of filters to cut off specific wavelengths of light while allowing the required light to pass through. [0004] Optical sensors, by converting light signals into electrical signals, and finally get video signals. [0005] The image processing unit is used for computing and processing the video signal transmitted by the optical sensor. [0006] The control unit is used to obtain the gain value in the image p...

Problems solved by technology

However, since in practical applications, the brightness of the environment may change in a short period of time, the above solution may cause the camera to repeatedly switch between black and white and color modes in a short period of time, that is, color-to-black or black-to-black The vibration problem of color, even when the color turns to black or black turns to color, there will be problems such as damage to the transmission device
