Embodiment 1

[0067] figure 1 A flow chart of the method for suppressing strong light and enhancing contours and details of a video image provided by the first embodiment of the present invention is shown. Such as figure 1 As shown, according to the first embodiment of the present invention, the sub-video image strong light suppression, contour and detail enhancement processing method includes:

[0068] Step S1, perform initialization settings, obtain the video image in the original video in real time through the image sensor, and obtain the standard curve corresponding to the video image, the standard curve is the relationship between the light and the video output voltage;

[0069] Step S2, according to the preset target curve, adjust the standard curve corresponding to the video image according to the target curve to obtain the video image after the strong light suppression processing, and the target curve is the preset output characteristic curve;

[0070] Step S3, converting the vide...

Embodiment 2

[0133] Such as Figure 5 As shown, the video image strong light suppression, contour and detail enhancement processing method of the present invention is set into three modules for specific description: these three modules are respectively: a camera setting module, a strong light suppression module and a contour and detail enhancement processing module; Wherein, the camera setting module is the setting performed before the video image strong light suppression, contour and detail enhancement processing method of the present invention, the strong light suppression processing of the video image is performed through the strong light suppression module, and the video image is processed through the contour and detail enhancement processing module. Contour and detail enhancement processing. It should be noted that the video image glare suppression, contour and detail enhancement processing method in Embodiment 1 is aimed at processing one frame of video image. When the glare suppress...

Embodiment 3

[0158] Such as Figure 10 As shown, according to the system corresponding to the video image highlight suppression, contour and detail enhancement processing method, that is, the video image highlight suppression, contour and detail enhancement processing method in Embodiment 1 of the present invention can be realized by the hardware in the following system, so The systems described include:

[0159] Image sensor, video signal processor, standard converter, video signal output circuit, digital video processor, communication chip, memory, storage chip and clock generator;

[0160] The image sensor, the standard converter and the video signal output circuit are respectively connected with the video signal processor, and the video signal processor, the communication chip, the memory, the storage chip and the clock generator are respectively connected with the digital video processor;

[0161] The image sensor is used to collect video images, the video signal processor is used to...

Abstract

The invention provides a method and a system for video image strong light suppression and contour and detail enhancement processing. The method comprises the following steps: performing initialization setting, obtaining a video image in an original video through an image sensor in real time, and obtaining a standard curve corresponding to the video image, wherein the standard curve is a relation between light and video output voltage; adjusting the standard curve corresponding to the video image according to a preset target curve, and obtaining a video image after strong light suppression processing, wherein the target curve is a preset output characteristic curve; performing system conversion on the video image to be outputted through a video system converter, and obtaining an outputted video image. According to the method and the system for video image strong light suppression and contour and detail enhancement processing, while the video image is subjected to strong light suppression processing, an area with weak light is subjected to enhancement processing, and the video image is subjected to contour and detail enhancement processing, so that a target can be clearly seen from a strong light position and a weak light position as far as possible.

Description

technical field [0001] The invention relates to the field of video image processing, in particular to the video image processing of a vehicle-mounted camera. Background technique [0002] In recent years, the vehicle-mounted front-view camera application system has developed rapidly, and various new requirements are put forward for the technology of the vehicle-mounted camera. For example, the requirements of the shooting angle, the number of pixels of the camera, and so on. But first of all, the camera must be able to clearly observe the cars, bicycles and pedestrians in front of the vehicle. This is the most basic requirement. [0003] Seeing objects clearly is the first and most basic need. In the real car driving process, it is easier to see clearly when shooting in the daytime, but when driving at night, there is a situation that seriously interferes with the clear shooting of the camera is the various strong light sources on the road, mainly the headlights of the op...
