Abstract

The invention provides testing equipment, a testing method and a testing device based on an imaging system. The testing equipment comprises a light source and a testing card; the light source and the imaging system are arranged at an interval; the test card is arranged on the light emitting side of the light source, and the test card is provided with a light hole; the light emitted by the light source can penetrate through the light-transmitting hole to be collected by the imaging system, and the light-transmitting hole can form a light spot image in the imaging system; and the light spot image can be used for interpreting the blurring degree of the imaging system. According to the testing equipment based on the imaging system, the testing card with the light hole is arranged, and the light emitted by the light source can be collected by the imaging system through the light hole, so that the light hole can form the light spot image on the imaging system, and the light spot image can be used for quantitatively measuring the blurring degree of the imaging system.

Description

technical field [0001] The present application relates to the technical field of imaging systems, in particular to testing equipment, testing methods and testing devices based on imaging systems. Background technique [0002] The current development trend of mobile phone cameras is to increase the size of image sensors and adopt lens groups with higher resolution and larger apertures. With the support of these hardware, users can be provided with better photo and video shooting effects. Based on this, users have higher and higher requirements for images. For example, for some images such as portrait photos or close-up photos, the user hopes that the image can achieve a background blur effect. [0003] However, there is currently a lack of quantitative characterization methods for the blurring capabilities of imaging systems such as cameras, and most of them rely on subjective judgments of the blurring capabilities of imaging systems, with large differences.
