Abstract

The invention discloses a detection method and detection device of a digital camera, wherein the method comprises: step 1: moving the focus lens to be tested to the place closest to the object to be photographed; step 2: performing automatic exposure control until the central area of ​​the image The average brightness reaches a stable state; Step 3: Lock the automatic exposure control parameters; Step 4: Take the first picture; Step 5: Determine the respective sizes of the four-corner areas in the first picture; Step 6: Count the respective sizes of the four-corner areas Average brightness; Step 7: In the case that the respective average brightness of the four corner regions is consistent, it is determined that the focus lens under test is not skewed. The embodiment of the present invention solves the technical problem of how to automatically and efficiently detect whether the focusing lens is skewed.

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 smart hardware, digital cameras with auto-focus function are becoming more and more popular. Although the camera has been tested before leaving the factory, the lens may still be damaged after being transported and assembled after leaving the factory. For example: the case where 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, heavy workload, high cost and difficult to unify the judgment scale. [0004] In view of this, the present invention is proposed. Contents of the invention [0005] The main purpose of the embodiments of the present invention is to provide a detection me...
