Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0024] Such as figure 1 As shown, the camera test device disclosed in the present invention includes an image device 1, a camera 4 and a fixing device 2 thereof, the image device 1 provides images for testing, the camera 4 is placed on the fixing device 2, and the camera 4 The image can be collected from the image device 1, and the present invention is also provided with a lens group 3 between the image device 1 and the fixing device 2, and the lens group 3 can be used to simulate different distances. The camera 4 Focusing is achieved at different simulated distances through the lens group 3, and then the image is collected and saved as a test image, and then the test image is compared with the original image of the imaging device 1 to determine the imaging effect of the camera 4 .

[0025] Because the camera test d...

Abstract

The invention discloses a camera testing device which comprises a video set providing videos, a camera and a fixing device for the camera. The camera testing device further comprises a lens set which is disposed between the video set and the fixing device and is used for simulating different shooting distances. Different distances can be simulated to test focusing imaging effect of the camera by adjusting the lens set with no need of moving the camera or the video set. Therefore, differences between factors such as light and angle caused by moving of the camera or the video set are avoided, repeatability and standard of tested images are increased, and accuracy in judging imaging effect of the camera is increased. These effects are achieved just by simply adjusting the lens set with no need of continuously correcting the factors such as light and angle during shooting, time and labor are saved, accuracy is guaranteed and efficiency is improved greatly.

Description

technical field [0001] The invention relates to the testing field of photographic equipment and components thereof, in particular to a camera testing method and device thereof. Background technique [0002] Optical cameras are mainly used in electronic devices such as mobile phones and digital cameras to capture light emitted by external objects for optical imaging. In order to ensure the imaging effect of the camera, it is necessary to test the produced camera, and in the prior art, during the test, various instruments and equipment are used to shoot various scenes in real scene, or to shoot a specific image on an imaging device , and then compare and analyze the imaging effect of the obtained results. The former real scene shooting is easily affected by the surrounding environment changes of the scene, and there may be deviations in the scene, angle, light and other factors of the scene during shooting, while the latter is in the shooting process whether it is Moving the ...
