Problems solved by technology
However, during the use of digital cameras, the quality of the photos taken may be poor due to various reasons. The so-called poor quality may be that the colors of the photos are too messy, the characters have red eyes, overexposure, poor photo layout and / or clarity Poor wait, some of these photos are therefore crap
In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: people can only distinguish which photos are of good quality and which are photos of poor quality only through manual screening. , will cause great inconvenience to people, that is, the existing technology cannot automatically evaluate the photo quality

The invention discloses an image quality evaluation device and a method thereof. The device comprises a picture analyzer and an evaluation unit. The picture analyzer is used for analyzing the parameters of the image so as obtain parameter values. The evaluation is used for evaluating the quality of the parameter values according to the predetermined criteria and outputting evaluation results. The invention also discloses a method for evaluating the quality of the image, which comprises that: the parameters of the image are analyzed so as to obtain the parameter values; quality evaluation is carried out on the parameter values according to the predetermined criteria and evaluation results are output. The image quality evaluation device and a method thereof analyzes the parameters of the image so as to obtain the parameter values; then the parameter values are output according to the predetermined criteria. In such a way, the invention can automatically evaluate the quality of pictures, thus reducing manpower consumption. In addition, the amusement function is also increased.
Description
technical field [0001] The invention relates to the field of digital image processing, in particular to an image quality evaluation device and method. Background technique [0002] At present, digital products have been widely used in all aspects of people's lives, and digital cameras are an indispensable partner when people party or travel. However, during the use of digital cameras, the quality of the photos taken may be poor due to various reasons. The so-called poor quality may be that the colors of the photos are too messy, the characters have red eyes, overexposure, poor photo layout and / or clarity Poor wait, some of these photos are therefore useless. In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: people can only distinguish which photos are of good quality and which are photos of poor quality only through manual screening. , will cause great inconvenience to people, that is, the prior ar...
