Problems solved by technology
[0003] However, due to the mechanism error in the assembly process of the image sensing module, the mechanism error will affect the positional relationship of the lens relative to the reference on the lens barrel. The error is compensated and it is not convenient for the focusing wheel mechanism to bite the lens, and when the error of the mechanism exceeds the allowable range, it will cause the focusing device to fail to perform automatic focusing

The invention provides a method for adjusting and detecting an image sensing module. The method comprises the following steps of: (1) calculating a traverse offset and a longitudinal offset of a central point of a lens and a rotation offset of the lens relative to a reference position of a lens cone according to position information of the lens of the image sensing module in the image sensing module; (2) compensating the traverse offset and the longitudinal offset of the central point of the lens and the rotation offset of the lens to accurately position the lens; and (3) adjusting the focus length of the image sensing module. By the method for adjusting and detecting the image sensing module, the mechanism error of image sensing module assembling can be compensated, so that the accurate focusing of the image sensing module can be realized. The invention also provides a device for adjusting and detecting the image sensing module.
Description
technical field [0001] The invention relates to an adjustment detection method, in particular to an automatic adjustment detection method and device for an image sensing module. Background technique [0002] At present, the image sensing module mainly includes a circuit board, an image sensor mounted at the center of the circuit board, a lens barrel fixed on the circuit board, and a lens mounted on the lens barrel directly above the image sensor. In the process of assembling the image sensor module, after the lens is installed in the lens barrel, it is necessary to adjust the focus of the lens, that is, to adjust the distance between the lens and the image sensor. There are mainly two existing focusing methods: the first one is manual focusing, and the manual adjustment detection method completely depends on the personal judgment of the focusing staff, and the accuracy of focusing varies from person to person, so it will be Affects the consistency of focusing of the image s...
