Problems solved by technology

[0005] However, in the scanning mode switching method in the prior art, since a hardware structure such as a special sensor needs to be used to detect whether the transmission manuscript holder is inserted into the scanner, the structure of the scanner is complicated, and the production cost of the scanner is increased.

Embodiment 1

[0064] See figure 1 , Is a flowchart of the scanning mode switching method disclosed in the first embodiment of the present invention. Such as figure 1 As shown, the method includes steps:

[0065] S101: Use the scanning light source of the scanner to scan the scanning space where the document to be scanned is not inserted to obtain a scanning space image;

[0066] The scanning light source (such as the transmission light source TPO) of the scanner was originally the light source used when scanning the document to be scanned. In this step, the scanning light source of the scanner is used to scan the scanning space where the document to be scanned is not inserted, and the scanning space image can be obtained.

[0067] Usually when scanning the transmission manuscript, in order to fix the transmission manuscript, the transmission manuscript is placed in the transmission manuscript holder for scanning. Specifically, it is necessary to insert the transmission manuscript holder into the...

Embodiment 2

[0077] See figure 2 , Is a flowchart of the scanning mode switching method disclosed in the second embodiment of the present invention. Such as figure 2 As shown, the method includes steps:

[0078] S201: Use the scanning light source of the scanner to scan the scanning space where the document to be scanned is not inserted to obtain a scanning space image;

[0079] The scanning light source (such as the transmission light source TPO) of the scanner was originally the light source used when scanning the document to be scanned. In this step, the scanning light source of the scanner is used to scan the scanning space where the document to be scanned is not inserted, and the scanning space image can be obtained.

[0080] Usually when scanning the transmission manuscript, in order to fix the transmission manuscript, the transmission manuscript is placed in the transmission manuscript holder for scanning. Specifically, it is necessary to insert the transmission manuscript holder into ...

Embodiment 3

[0092] See Figure 5 , Is a flowchart of the scanning mode switching method disclosed in the third embodiment of the present invention. See Figure 5 , The method includes the steps:

[0093] S501: Determine whether a document to be scanned is inserted into the scanner;

[0094] If yes, go to step S502; otherwise, end the process.

[0095] Generally, the scanner has a document sensor to be scanned, which can sense whether a document to be scanned is inserted into the scanner. Therefore, the sensor result of the document to be scanned can be used to determine whether the document to be scanned is inserted into the scanner.

[0096] S502: Use the scanning light source of the scanner to scan the scanning space where the document to be scanned is not inserted to obtain a scanning space image;

[0097] S503: Calculate the size of the area that is not blocked in the scanned space image;

[0098] S504: Determine whether the size of the area where there is no occlusion meets the second standar...

Abstract

The invention discloses a scan mode switching method which comprises the following steps: utilizing scan light source of a scanner to scan scanning space of a manuscript to be scanned to obtain a scanning space image; according to the scanning space image, determining whether the scanning space exists a transmission draft holder or not; if so, switching a scan mode or keeping the scan mode as a transmission manuscript scanning mode; if not, switching the scan mode or maintaining a reflection manuscript scan mode. The invention also discloses a scan mode switching system. By employing the method and the system disclosed in the invention, a hardware structure detecting the transmission manuscript holder in the prior art is omitted, a structure of a scanner is simplified, production cost of the scanner is reduced, simultaneously scan modes of the scanner can be switched accurately.

Description

Technical field [0001] The present invention relates to the scanning field, in particular to a scanning mode switching method and system. Background technique [0002] Scanner is a device that uses photoelectric technology and digital processing technology to convert graphics or image information into digital signals by scanning. [0003] Generally, the objects scanned by the scanner, that is, the documents to be scanned, can be divided into two categories: reflective documents and transmissive documents. Reflective manuscripts refer to manuscripts such as developed photographs and paper with printed text. Since the material of this kind of manuscript itself is opaque, the scanning of this kind of manuscript requires the use of a contact image sensor (CIS) module based on the principle of reflection. Transmission manuscripts refer to manuscripts such as processed films. Since the material of this kind of manuscript is transparent (translucent), scanning of this kind of manuscrip...
