Title:
IMAGE SCANNING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/103427
Kind Code:
A1
Abstract:
Provided is an image scanning system. The image scanning system comprises a scanning unit. The scanning unit comprises: a plurality of lenses, wherein the plurality of lenses are arranged in sequence in a scanning direction, and the scanning direction is a lengthwise direction of a target object; and a plurality of photoelectric conversion chips, wherein the photoelectric conversion chips and the lenses are disposed opposite each other in a spaced manner in a predetermined direction and correspond to each other on a one-to-one basis, any two adjacent imaging regions of the scanning unit are at least connected, and the predetermined direction is the direction of extension of optical axes of the plurality of lenses, such that the image scanning system realizes seamless scanning. The distance between any two adjacent lenses is not limited. Compared with a plurality of area-array cameras in the prior art, the distance between the photoelectric conversion chips and the lenses in the predetermined direction can be shorter, such that it can also be ensured that imaging regions of any two adjacent photoelectric conversion chips in the scanning direction partially overlap, without the need to decrease the magnification of a scanned image. That is, the system ensures the high resolution of the scanned image while realizing seamless scanning.
