Problems solved by technology

As a monitoring device, the most convenient way to face and process the LOG curve (a logarithmic gamma curve) output by many cameras is to directly determine the quantized value of the electrical characteristics in the LOG format signal (hereinafter referred to as the quantized value), which is intuitive and accurate. But the subjective wishes of the electrical engineers were not recognized by the photographers
The photographer's adjustment to the exposure is non-linear, and can only increase or decrease the exposure exponentially, while the quantization value changes linearly, so the photographer cannot intuitively understand and apply the existing auxiliary exposure tools

Abstract

The invention provides an image assisted exposure processing method and apparatus, and an electronic device, and relates to the technical field of data processing. The method comprises the following steps: Obtaining a target image to be processed and a target signal format to which the target image belongs; determining respective brightness ranges of a plurality of set color lumps according to thetarget signal format, wherein there is a corresponding relationship between the plurality of set color lumps and a plurality of set exposure gears; and generating an exposure gear pseudo color map corresponding to the target image according to the brightness values of respective pixel points of the target image and the brightness ranges of the set color lumps. The exposure gear pseudo color map obtained by using the image assisted exposure processing method and apparatus, and the electronic device provided by the invention can intuitively indicate the exposure effect through the set color lumps having the corresponding relationship with the set exposure gears, therefore, users such as a cameraman can intuitively and conveniently understand and use the exposure gear pseudo color map, and the use convenience of the users is improved, so that the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to an image-assisted exposure processing method, device and electronic equipment. Background technique [0002] During the shooting process of the photographer, ensuring the correctness of the exposure of the captured material is one of the important tasks of the shooting work. The most direct method they use is to increase or decrease the aperture, and the quantitative standard is to adjust the exposure by adding or subtracting the aperture. [0003] The photosensitive devices of modern cameras are developing rapidly, and their tolerance is constantly improving. For various monitoring equipment, the improvement of the tolerance of its physical characteristics is far behind the development of photoreceptors. In this way, when the photographer watches the exposure on the monitor, there is a risk of misjudgment of the exposure due to insufficient latitude of the moni...
