Day and night high-definition and dual-mode camera and image processing method thereof

Abstract

The invention provides a novel day and night high-definition and dual-mode camera and an image processing method thereof. The principle that an image sensor can sense both visible light and infrared is utilized. Different image effect adjustment procedures under different light intensities in a central processing unit are stored in different storage units respectively. A visible light acquisition unit acquires the external visible light, and then the central processing unit is connected to the different storage units according to the intensity of the visible light, i.e., different image effect adjustment-procedures are called, and then the image signals acquired by the image sensor are processed differently, i.e., color image shooting is performed in the daytime and infrared shooting is performed at night, and the acquired video signals are adjusted to be in a black and white state so that more clear and bright images can be obtained no matter in the night or daytime.

Description

technical field [0001] The invention discloses a camera and an image processing method, in particular to a day and night high-definition dual-mode camera and an image processing method of the camera. Background technique [0002] As an indispensable device in the security field, the camera plays a vital role in the security monitoring field. The quality of the camera directly affects the quality of the entire monitoring system. Traditional cameras only have a single function of daytime or nighttime photography, which can no longer meet people's needs, so dual-mode cameras have emerged at the historic moment. At present, there are various ways to realize dual-mode cameras. Please refer to the announcement numbers: CN201118758Y, The patent number is: 200720100216, which installs an infrared generator on the camera, and emits infrared rays invisible to the human eye through the infrared generator at night. After the light is reinforced in the monitoring area, the camera is used...

Problems solved by technology

[0003] Aiming at the shortcomings of the above-mentioned camera in the prior art that the image is not clear enough, bright enough, and only has dual-mode operation when shooting at night, the present invention provides a new day and night high-definition dual-mode camera and an image processing method, which utilizes image The principle that the sensor can sense both visible light and infrared rays, stores different image effect adjustment programs under different light intensities of the central processing unit in different storage units, collects external visible light through the visible light collection unit, and according to the intensity of visible light The central processing unit is connected to different storage units, that is, different image effect adjustment programs are called, and the image signals collected by the image sensor are processed differently, color photography is performed during the day, infrared photography is performed at night, and the collected video signals are adjusted. To black and white state, so that no matter in day or night will get clearer and brighter images
