Abstract

The invention discloses a digital camera detection method and a detection device. The digital camera detection method is characterized in that S1, a focusing lens to be detected can be moved to a place closest to a shot object; S2, automatic exposure control can be carried out, till average brightness of an image central area reaches a stable state; S3, automatic exposure control parameters can be clocked; S4, a first picture is shot; S5, the sizes of four corner areas of the first picture can be determined; S6, the average brightness of the four corner areas can be respectively calculated; S7, when the average brightness of the four corner areas is identical, the focusing camera to be detected is not deflected. The technical problem of automatic high-efficiency detection of deflection of the focusing lens can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of cameras, and in particular, to a detection method and a detection device for a digital camera. Background technique [0002] In the era of the popularization of intelligent hardware, digital cameras with autofocus function are becoming more and more popular. Although the camera has been inspected before leaving the factory, after the lens has been transported and assembled after leaving the factory, the lens may still be damaged. For example: when the lens is skewed. [0003] At present, the detection of lens damage is carried out by manual sorting. This approach requires a shot-by-shot judgment. Therefore, this method is time-consuming, labor-intensive, costly and difficult to unify the judgment scale. [0004] In view of this, the present invention is proposed. SUMMARY OF THE INVENTION [0005] The main purpose of the embodiments of the present invention is to provide a dete...
