Title:
カメラモジュール調整装置及びカメラモジュール調整方法
Document Type and Number:
Japanese Patent JP6729960
Kind Code:
B2
Abstract:
[Problem] To provide a camera module adjustment device and a camera module adjustment method, wherein when adjusting the distance between a camera module lens and an image capturing element, the image capturing element is driven and an image of a test chart is not captured. [Solution] According to the present invention, a light spot, on which parallel light beams are focused by a lens of a camera module, is formed on an image capturing element of the camera module. An image signal is generated by an image capturing element of an image capturing unit by being photoelectrically converted from a light spot on which parallel light beams are focused by a collimator lens of the image capturing unit, wherein the parallel light beams are converted, from the light reflected by the light spot in the image capturing element, to be approximately parallel by means of a lens. An adjustment of the camera module is performed on the basis of the distance between the image capturing element and the lens of the camera module, said distance being determined on the basis of a focus evaluation value calculated for the light spot on the basis of the image signal.
