Problems solved by technology

[0002] In the test of camera imaging quality, related technologies manually import the photos obtained by taking pictures into professional photo analysis tools (for example, imagetest), and manually operate the photo analysis tools to check the color restoration accuracy, white balance, etc. of the photos. The objective indicators are tested one by one, and the related technology is completely dependent on manual work, so the test efficiency of photos is low

Abstract

The invention relates to a method and apparatus for testing image quality. The method comprises the following steps: determining a color component of a target area in a tested image in a first color space; converting the color component of the first color space into a color component in a second color space; judging, according to the color component in the second color space, whether a color restoration value of the tested image is within a preset range, and obtaining a test result; and generating a prompt message of color restoration quality of the tested image according to the test result. According to the technical scheme provided by the invention, testers are enabled to intuitively obtain related information of the image quality, the image quality is automatically tested, and the test efficiency of the image quality is improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to a method and device for testing image quality. Background technique [0002] In the test of camera imaging quality, related technologies manually import the photos obtained by taking pictures into professional photo analysis tools (for example, imagetest), and manually operate the photo analysis tools to check the color restoration accuracy, white balance, etc. of the photos. The objective indicators are tested one by one. Since the related technology is completely dependent on manual work, the efficiency of photo testing is low. Contents of the invention [0003] In order to overcome the problems existing in related technologies, embodiments of the present disclosure provide a method and device for testing image quality, so as to realize automatic testing of image quality and improve testing efficiency. [0004] According to a first aspect of an embodiment o...
