Image scanning method, device and reader

Abstract

The embodiment of the invention discloses an image scanning method, device, a reader and a computer readable storage medium, wherein the method comprises the following steps: if the to-be-scanned paper is detected through a first sensor array, controlling a stepping motor to drive the to-be-scanned paper in the paper feeding channel of the reader to advance, wherein the direction angle of the to-be-scanned paper into the reader is arbitrary; and if a second sensor array detects that the head of the to-be-scanned paper reaches the upper edge of a CIS scanning array, controlling the CIS scanningarray to enter a scanning state to scan the to-be-scanned paper after the to-be-scanned paper advances for a distance L0; and if the second sensor array detects that the tail of the to-be-scanned paper goes away from the lower edge of the CIS scanning array, controlling the stepping motor to drive the to-be-scanned paper to advance for a distance L4, and then turning off the CIS scanning array. According to the invention, the scanning of the to-be-scanned paper in any direction and angle can be realized.

Description

technical field

[0001] The invention belongs to the field of image technology, and in particular relates to an image scanning method, device, reader and computer-readable storage medium. Background technique

[0002] The Contact Image Sensor (CIS) is an important component of the CIS reader. Among them, CIS, stepper motor and analog front-end chip are the core components of the contact image scanner.

[0003] At present, the paper to be scanned placed in any direction and angle may be incompletely scanned, resulting in incomplete captured images and other problems. The paper path where the paper to be scanned is placed in the CIS reader must be placed in a fixed direction. For example, when the reader is a lottery reader and the paper to be scanned is a lottery ticket, the direction of the lottery ticket must be placed in parallel. , cannot be placed in any direction or angle.
