Taking the conversion to YUV space as an example, the process of color protection degree adjustment is as follows: transfer the RGB value of the image captured by the industrial camera to the YUV space, perform color adjustment in the YUV space, and then convert it to RGB after completion, and output the adjusted Image, in the process of color adjustment, involves a total of two data conversions, which consumes a lot of system resources and requires high data processing performance of the hardware in the process, which in turn increases the production cost of industrial cameras

The invention discloses an industrial camera color adjustment method. The method comprises: 1, acquiring original RGB image data in a to-be-processed image in an industrial camera, calculating the product of the original RGB image data and a saturation adjustment matrix, generating an overall saturation adjustment image, and the saturation adjustment matrix being determined by saturation parameters and an image color conversion matrix; and 2, selecting at least three reference colors in the hue loop, determining a hue adjustment step length and a saturation adjustment step length according tothe reference colors and an adjustment direction in user preference setting, and performing color dimension adjustment of different dimensions on the overall saturation adjustment image in sequence togenerate a color adjustment image. By means of the technical scheme, system resources consumed by matrix conversion in the color adjusting process are reduced, the image processing speed is increased, multiplication and addition in the image processing process are reduced, the method can be executed by a programmable gate array of an industrial camera, and the cost of the industrial camera is reduced.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular, relates to a color adjustment method for an industrial camera. Background technique [0002] Since the problems faced by visual inspection and the algorithms used are different, and there are obvious differences in the subjective feelings of the human body, industrial cameras need to provide color adjustment functions to allow users to adjust colors according to their own needs. There are currently two types of color adjustment: overall color adjustment and different-dimensional color adjustment. Among them, the overall color adjustment is to meet the user's adjustment of the overall saturation of the image, and the different-dimensional color adjustment is for differences in different cameras, environments, and algorithms. Select different colors for individual hue and saturation adjustments. [0003] In the image signal processing (ISP) of existing industr...
