Problems solved by technology
The occurrence of this phenomenon has a very large negative impact on image resolution and intelligent image recognition, reduces the camera's ability to adapt to the shooting environment, and cannot meet the user's requirements for high-quality images
And if a complex post-processing algorithm for image optimization is used, the time-consuming calculation of the algorithm will cause delays in image processing, which cannot meet the real-time requirements of users for real-time capture and evidence collection. At the same time, the complex algorithm requires the use of High-performance processor, the existing high-definition CCD capture camera does not have an additional high-performance processor

The invention relates to the technical field of image processing, and in particular relates to an image processing method and system. The image processing method comprises the steps of: determining position information of each pixel of a current image, and a quantized value of each pixel; determining a photosensitive area and a non-photosensitive area of the current image according to the position information of all pixels of the current image, moreover, for the same line of pixels in the non-photosensitive area, determining an average value of the quantized values of the line of pixels; and for the photosensitive area, comparing the exposure time of the current image with a preset exposure value, and processing the quantized value of each pixel in the photosensitive area according to a comparison result. According to the invention, the problem of influence on the image quality by semitransparent light pillar phenomena is effectively solved, no delay exists in a processing process, and the instantaneity in the processing process is ensured.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and system. Background technique [0002] At present, with the continuous improvement of the technology of cameras used for road capture in the intelligent transportation industry, high-definition CCD capture cameras have gradually replaced the original standard-definition capture cameras. However, due to the substantial increase in the number of pixels of the CCD sensor, the phenomenon of translucent light beams is more obvious. When the high-definition CCD sensor is working, it first performs photoelectric conversion, then transfers the collected charges to the vertical register, and then transfers the charge of the vertical register to a horizontal register through a specific driving method. The pixel is the unit to move the charge out of the CCD sensor, so as to realize the function of photoelectric conversion and output. However, ...
