Embodiment Construction

[0061] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0062] The present invention adds an image processor for detecting the current focus quality of the camera to the existing camera focus detection system, and the image processor performs real-time analysis on the video signal output by the camera during the focus adjustment process of the camera Processing to judge whether the focus performance of the camera is qualified.

[0063] figure 2 Shown is a schematic structural diagram of the camera focus performance detection system. It can be seen from the figure that the system mainly includes:

[0064] Camera: used to capture test images;

[0065] Image processor: connected between the camera and the display device. During the focus adjustment process of the camera, the real-time focus quality detection result of the camera is obtained by analyzing and processing the video signal output b...

Abstract

The invention discloses a camera focus performance detection system and method, which are used to solve the problems of low detection efficiency and high detection error rate when the focus performance of the camera is detected manually in the prior art. The present invention adds an image processor between the camera and the display device of the existing camera focus detection system, and the image processor obtains the focus performance detection of the camera by analyzing and processing the video signal output by the camera during the focus adjustment process of the camera result. The invention greatly improves the efficiency and correctness of the detection of the focus performance of the camera, and at the same time reduces the labor intensity of detection workers.

Description

technical field [0001] The invention relates to detection technology in the field of multimedia communication, in particular to a camera focusing performance detection system and method. Background technique [0002] During the production and processing of the camera, it is finally necessary to perform a focus performance test on the camera to exclude cameras that cannot focus normally. This process is usually done by observing the sharpness of the test image captured by the camera with the human eye. [0003] figure 1 Shown is a schematic diagram of the focus performance detection of the camera by human eye observation. When performing focus performance testing, it is necessary to connect the output of the camera to the display device, and then point the camera at the test image set on the test card, then the test image will be displayed on the display device, manually adjust the focus of the camera, and the display device The sharpness of the test image displayed on the...
