specific Embodiment approach

[0067] see below figure 2 , which is a specific implementation of the brightness uniformity detection method of the supplementary light camera according to the embodiment of the present invention, including the following steps:

[0068] In step 201, an image to be detected is obtained from a supplementary light camera.

[0069] Among them, in the preparatory work, both the supplementary light camera and the solid color plate were placed in the dark room. The solid color board is pure gray or pure white. In a dark room, place the light-filling camera and the solid color plate opposite, for example, facing each other. The surface of the solid color plate covers the complete field of view of the light-filling camera, so that the preview interface of the light-filling camera is all the surface of the solid color plate. When shooting, the fill light of the fill light camera is used as the only shooting light source in the dark room, and the solid color plate is photographed to ...

Abstract

The invention discloses a brightness uniformity detection method and device for a light supplement type camera, and the method comprises the steps: obtaining a to-be-detected image from the light supplement type camera, and obtaining the brightness value of a central region and / or the brightness values of a plurality of edge regions from the to-be-detected image; carrying out effective brightness uniformity detection on the light supplement type camera by using the brightness value of the central area and / or the brightness values of the plurality of edge areas. Therefore, brightness uniformity detection is carried out on the light-supplementing type camera by detecting the to-be-detected image without using brightness detection equipment, and the imaging quality of the to-be-detected image can intuitively reflect the product quality of the light-supplementing type camera, so that the detection method is accurate and effective for the light-supplementing type camera.

Description

technical field [0001] The present application relates to the field of camera detection, in particular to a method and device for detecting brightness uniformity of a supplementary light camera. Background technique [0002] With the continuous development of camera manufacturing technology, there are more and more types of cameras, such as conventional cameras, waterproof cameras, supplementary light cameras and so on. Take the supplementary light camera as an example, the lack of light will affect the image quality of other types of cameras when shooting at night, and the supplementary light camera uses supplementary lights to supplement light when the light is insufficient, which can make up for this defect. [0003] Since the supplementary light effect of the supplementary light camera itself will also affect the image quality, a number of tests, such as brightness uniformity tests, will be carried out during its manufacturing. If the brightness uniformity of the supple...
