Problems solved by technology

[0004] Although the design of this switchable black and white background can meet the requirements of edge detection and characteristic correction, relatively, there are many components to control the switching of the background film, so the design is not only complicated, but also takes up a lot of space

Embodiment Construction

[0049] figure 1 A schematic diagram showing a scanner with background components according to a preferred embodiment of the present invention. Such as figure 1 As shown, the scanner 1 of this embodiment includes a reference color plate 10 , a scanning component 20 and a light shielding plate 30 . The reference color plate 10 , the scanning component 20 and the light shielding plate 30 are installed in the body component 90 , and the body component 90 includes a first body 92 and a second body 94 . The first body 92 and the second body 94 form the paper feeding channel 80 .

[0050] The reference color board 10 may be a white color board or a color board of other colors. The light shielding plate 30 can be a colored transparent plate, an opaque plate or a semi-transparent plate. The combination of the reference color plate 10 and the shading plate 30 can be referred to as a background component. The shading plate 30 and the reference color plate 10 can be arranged parallel...

Abstract

The invention discloses a scanner with background assemblies, including a reference colour palette, a scanning assembly and a shading plate. The scanning assembly faces to the reference colour palette and is used for scanning a reference block of the reference colour palette arranged on a scanning region and an original manuscript block of an original manuscript. The scanning assembly includes a light source. The light source projects a first ray towards the reference block and projects a second ray towards the original manuscript block. The shading plate is arranged between the reference colour palette and the scanning assembly. The shading part of the shading plate is arranged in a first light path where the first ray advances, and is used for blocking part of the first ray from being projected to the reference block, and the shading part of the shading plate is arranged outside a second light path where the second ray advances.

Description

technical field [0001] The present invention relates to a scanner with a background component, in particular to a background component that uses a shading plate to block part of the light from reaching the reference color plate, so as to perform the characteristic correction procedure of the scanner and assist the foreground by means of the reference color plate detection. Background technique [0002] In traditional scanners, a white calibration sheet is usually provided to assist the characteristics of the light source and image sensor of the scanner. However, the white calibration sheet cannot provide the auxiliary foreground detection function for documents with white edges, and will affect the scanned image quality. Especially in the application of the sheet-fed scanner, because the scanning module is in a fixed state, the white calibration sheet is arranged above the scanning window and at the scanning position where the scanning module reads the document. If the lig...
