Problems solved by technology

When the motor speed increases, for example by υ o increase to υ i , the maximum torque that the motor can generate is given by τ o reduced to τ i , the stepping motor may not be able to stably drive the scanning module at this time, therefore, a larger or more expensive stepping motor must be used
In addition, when the dwell time of the stepping motor is shortened,

Embodiment Construction

[0022] specific implementation

[0023]The image sensing component of the present invention uses a CCD module used in a scanner as an example to illustrate how the image sensing component improves scanning resolution. As shown in FIG. 2(A), it is a schematic diagram of an image sensing component used in a scanner according to a preferred embodiment of the present invention. The scanner 200 includes an upper cover 210 and a base 220. The base 220 includes a scanning platform 221, an optical machine 223 and a circuit board 225. The scanning platform 221 is used to insert a document 222 to be scanned (taking a reflective document as an example), and the optical machine 223 also It includes a light source 224 , a mirror 226 , a lens group 227 and a CCD module 228 . When scanning documents, the light source 224 on the optical machine 223 projects a light L to the document 222 to be scanned. After being reflected by the document 222 to be scanned, the l...

Abstract

This invention relates to an image sensor package and its method. It include: The P red light sensing units, P green light sensing units and P blue light sensing units, the P is bigger than or equal to two, they are installed in an image scanning device, it can scanning and exposure sensing to several scanning lines on the scanning documents. The image scanning device include a driven device, used to move the image sensing package when scanning documents. When the image sensing package scanning the documents, every exposure can make the P red light sensing units, P green light sensing unit and P blue light sensing units sensing 3P scanning lines they are neighbor their several scanning lines, and when after the driven device relative moving with image sensing package along Y axis, the image sensing package then continuous sensing the 3P scanning lines, and repeat move till all the scanning lines are finished sensing.

Description

technical field [0001] The present invention relates to an image sensing component and its method, in particular to an image sensing component comprising at least two sets of red light sensing units, green light sensing units and blue light sensing units to improve resolution in the Y-axis direction and its methods. Background technique [0002] As shown in FIG. 1(A), it is a schematic diagram of an optical path of a traditional scanner scanning a document. Taking reflective documents as an example, the general way for scanners to capture images is to project light L from the lamp 110 to the document 112 to be scanned. After being reflected by the document 112 to be scanned, the light L enters the optical machine 113 and is reflected by the mirror 114. , and after being focused by the lens group 116, it is received by the charge coupled device (Charge Coupled Device, CCD) module 118, and the optical signal is converted into an electrical sign...
