Adjusting method for focus of optical image
This invention is related to an adjusting method for focus of optical image generated from a point source light penetrating an optical lens module, including: calculating a tilt vector T(X,Y), a diagonal value and an average value M in response to said four focus values of four corners of said optic...

| description | This invention is related to an adjusting method for focus of optical image generated from a point source light penetrating an optical lens module, including: calculating a tilt vector T(X,Y), a diagonal value and an average value M in response to said four focus values of four corners of said optical image; thereby adjusting the tilt direction and degree of said optical lens module, analysising on the source of tolerance of said optical lens module, and calculating the uniformity of focus of said optical image. |
