Abstract

The invention discloses an image filter processing method and device for quickly realizing multiple effects. First, an initial color reference map is generated, and the initial color reference map includes m*m color blocks, and the size of each color block is m2* m2, then adjust the color values ​​of each color block of the initial color reference map according to the required filter algorithm to obtain the corresponding filter reference map, and finally combine the color value of each pixel of the image to be processed with The filter reference map uses an interpolation algorithm to perform mapping processing to obtain the color value of each pixel of the image to be processed after being mapped by the filter reference map, thereby obtaining an effect map; it is not only fast, but also does not affect the effect of the filter. Effect. The multiple of performance improvement is approximately equal to the total number of algorithm steps of the filter, which greatly shortens the processing time in multi-step and large-batch processing.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image filter processing method for quickly realizing multiple effects and a device for applying the method. Background technique [0002] Digital images captured by digital shooting equipment are widely accepted and applied in real life and work. Considering the influence of factors such as digital camera precision and lighting environment, the obtained image effects may not be good enough, such as not bright enough colors, not bright enough. Good, bad color, etc., so we often use image processing software to enhance the effect of the image obtained after taking a photo, such as brightness / contrast adjustment, color scale adjustment, curve adjustment, exposure adjustment, color adjustment, etc. Balance adjustment, inverse color adjustment, threshold adjustment, saturation, optional color, color temperature, etc. After these processes, the effect of digital images can ...
