Method and device for determining image quality

The embodiment of the invention provides a method and device for determining an image quality, relates to the image field, and can determine a light source chromaticity parameter corresponding to an image color rendition quality with an evaluation value of a viewer, wherein the evaluation value is higher than a preset value. The method comprises the following steps: for each video segment, evaluation of the image quality by the viewer is obtained, wherein the video segment is captured in a preset light source chromaticity parameter condition; and according to the evaluation, the light source chromaticity parameter corresponding to the video segment with the evaluation value higher than the preset value by the viewer is determined. The method and device for determining the image quality is used to determine the evaluation of the viewer on the image quality.
