Abstract

The invention discloses an automatic focusing device when images are scanned. The device comprises a platform (1), a lens (2), a piezoelectric ceramic device (3) and an image collection device (4). An imaging sensor is arranged in the image collection device (4). The invention also discloses a method related to the device. Through adoption of the technique scheme, through utilization of computer data processing, the piezoelectric ceramic adjusting device and the image sensor, whether focusing is realized or not is judged according to the definitions of three images focused in different focal planes; rapid, real time and automatic focusing is carried out to the images of objects under detection with relatively high unevenness; the definitions of the images are improved; and the device is small in size and low in cost.

Description

technical field [0001] The invention belongs to the technical field of optical images, and relates to digital image processing technology. More particularly, the present invention relates to an automatic focusing device during image scanning. In addition, the present invention also relates to a related method of the device. Background technique [0002] The depth of field of an optical inspection system generally decreases as the resolution increases. [0003] like figure 1 As shown in the figure, when the object to be inspected, such as a flat panel display, a semiconductor wafer or a biomedical slice, has a curvature greater than this depth of field, it is necessary to design an automatic focusing system to make each image during inspection and scanning. all remain clear. [0004] However, in the prior art, there is still a lack of related application technologies. SUMMARY OF THE INVENTION [0005] The invention provides an automatic focusing device during image sca...
