Abstract

The invention discloses a method and system for evaluating pre-shot picture quality. The method comprises the following steps of: acquiring a preview picture within a time interval and sampling colors and brightness in a specific region of the preview picture; selecting two uniform-brightness regions serving as analysis regions from the preview picture according to the sampled brightness; outputting RGB(Red-Green-Blue) column diagrams of the analysis regions respectively according to the colors sampled from the preview picture, separating a R channel, a G channel and a B channel from each analysis region and establishing column diagrams for the three channels respectively so as to determine scoring channels; and calculating ideal column diagrams of the scoring channels respectively according to the RGB column diagrams of the analysis regions and comparing the ideal column diagrams of the scoring channels with the column diagrams of the scoring channels for scoring and displaying.

Description

technical field [0001] The invention relates to the field of digital imaging and image quality evaluation, in particular to a method and system for pre-photographing image quality evaluation. Background technique [0002] In recent years, the photographic function of digital products has developed rapidly, from traditional digital zoom to optical zoom of retractable lens, and the number of pixels has also grown to more than tens of millions. The shooting effect of high-end digital products can already be compared with professional cameras. [0003] But for ordinary users, too high pixels and too professional functions can only become the pursuit of fashion. How to achieve the best effect in actual shooting is a very difficult problem for ordinary users without professional shooting knowledge. Therefore, some systems for evaluating the shooting quality of digital photos have appeared in the market at present. Most of them evaluate the quality of the pictures taken by users b...
