Shooting type scanner for imaging local imaging surface

Abstract

The invention discloses a shooting type scanner for imaging a local imaging surface, which comprises a pedestal, a digital camera module, a folding arm, a rotating shaft and a supporting column installed on the pedestal. The digital camera module is installed on the folding arm; the folding arm is installed on the supporting column via the rotating shaft; the digital camera module comprises a sensor control chip, a sensor and a sensing lens; the sensor chip controls and is connected with the sensor; and the sensor is arranged in a local part of an imaging image surface of the sensing lens. Inthe shooting type scanner, the sensor of the digital camera module is arranged in the local part of the imaging image surface of the sensing lens to present complete image pickup, so that a position of the sensor can be adjusted arbitrarily; the extended folding arm can be greatly reduced, or the digital camera module can be directly installed at the front end of the supporting column to shoot a picture clearly without extending the folding arm; and the complete picture can be shot by directly using the partially imaged image surface of the lens.

Description

technical field [0001] The invention relates to the field of image scanning, in particular to a photographic scanner capable of imaging a local imaging surface. Background technique [0002] A scanner is a high-tech product integrating light, machinery and electricity. It is an important tool for inputting various forms of image information into a computer. It is the third-generation computer input device after the keyboard and mouse. Scanners have stronger functions than keyboards and mice. From the most original pictures, photos, films to all kinds of manuscript materials, they can be input into the computer with the scanner, and then realize the processing, management, use, Storage, output, etc., together with optical character recognition software OCR (Optic Character Recognize), can also convert scanned documents into computer text form. [0003] Such as figure 1 with figure 2 It is shown that the existing photographing scanner places the sensor 21 in the middle of ...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 and figure 2 It is shown that the existing photographing scanner places the sensor 21 in the middle of the imaging surface 23 of the lens 22, can photograph and scan the paper placed in the photographing area 24, and obtain a complete frame by adjusting the appropriate focal length, but This kind of scanner needs to expand the shooting area by extending the folding arm 20 as a price, sometimes when shooting traditional Chinese medicine, a larger folding arm is extended to expand the shooting area

[0004] The shortcoming of this kind of scanner equipment is that in the limited space where the folding arm cannot be stretched out, normal shooting will not be possible, and a larger imaging space can be opened up by drawing out the excessively long folding arm to ensure imaging It is complete, but it needs to take pictures through the extension and flip of the folding arm, and even takes up more space, which brings inconvenience to people's normal scanning
