OPTICAL DISPLACEMENT DETECTION APPARATUS AND OPTICAL DISPLACEMENT DETECTION METHOD THEREOF |
摘要 |
The present invention discloses an optical displacement detection apparatus and an optical displacement detection method. The optical displacement detection apparatus includes: a light source for projecting light on a surface; an image capturing unit for generating an image signal according to light reflected from the surface; and a processing unit for generating an auto-exposure (AE) state value and an image quality (IQ) value according to the image signal, and determining an AE range according to an initial AE range, the AE state value and the IQ value. |
