AI Technical Summary

Technical Problem

In the prior art, when mapping the linear optical signals of pixels in an image as nonlinear electrical signals, the mapping results are not accurate enough and are usually too different from expected.

Method used

By acquiring the first image, the brightness values ​​of the pixels in the image are converted based on the reference electrical signal values ​​corresponding to the plurality of reference luminance values ​​in the reference luminance value set to obtain the electrical signal values ​​corresponding to the pixels. The set of reference luminance values ​​is determined based on the brightness distribution of each pixel in the image, and the reference electrical signal value corresponding to the reference luminance value is its mapping value on the target mapping curve.

Benefits of technology

Through the precise definition of the reference luminance value set, the brightness distribution of most pixels in the image can be more accurately met, thereby improving the accuracy of the mapped electrical signal value.

Abstract

The embodiment of the invention discloses an image processing method, system and device, a storage medium and a program product, and the method comprises the steps: obtaining a first image; on the basis of reference electric signal values corresponding to a plurality of reference brightness values in a reference brightness value set, brightness values of pixels in the first image are converted, and electric signal values corresponding to the pixels are obtained; the reference brightness value set is determined based on brightness distribution of each pixel in the first image, and the reference electric signal value corresponding to the reference brightness value is a mapping value of the reference brightness value on a target mapping curve. According to the embodiment of the invention, the reference brightness value set is determined based on the brightness distribution of each pixel in the first image, so that the plurality of reference brightness values in the reference brightness value set can meet the brightness distribution of most pixels in the first image, and the brightness distribution of most pixels in the first image can be improved. The electric signal value obtained after the brightness value of each pixel in the first image is converted is more accurate.
