Portable scanning device for entering image and text via setting shooting area

Abstract

The utility model relates to a portable scanner for computer-based image and text file recording in a circled shoot area, belonging to computer TXT information record field. The utility model adopts the technical proposal of providing a portable scanner for TXT recording via a circled shoot area. The device comprises a piece of auto focusing camera equipment, an aperture adjusting device, a group of lamp tubes and a memory, wherein the lamp tube comprises a fixed lamp tube and a movable lamp tube, which are used for producing high brightness rectangle aperture on the irradiated target file; the aperture adjusting device adjusts the size of the aperture to circle the shoot area on the target file; the auto focusing camera equipment shoots the circled area immediately and memorizes the shot information to the memory of the device. The utility model has advantages of wide shoot range from a letter or a row of letters to a file more than a piece of paper with A4 size, strong agility and adaptability, and visualization and correctness, low cost, delicate appearance and portability.

Description

Technical field [0001] The invention belongs to computer peripheral equipment, in particular to the field of scanners, and is mainly applied to the entry of graphic and text information. Background technique [0002] At present, in addition to traditional scanners, there are high-cost digital cameras as equipment for image and text information entry, and digital cameras have a tendency to replace traditional scanners due to their portability and not occupying office space. Digital cameras generally frame the area to be photographed by directly observing its display screen. This method is indeed intuitive, but it requires a screen of appropriate size and capable of displaying images. Therefore, a digital camera with a shooting function needs to design a large enough display screen. It will increase the cost, and the point-and-shoot camera without a screen cannot accurately frame the effective shooting range. The large amount of useless information captured will cause the post...

Digital cameras generally frame the area to be photographed by directly observing its display screen. This method is indeed intuitive, but it requires a screen of appropriate size and capable of displaying images. Therefore, a digital camera with a shooting function needs to design a large enough display screen. It will increase the cost, and the point-and-shoot camera without a screen cannot accurately frame the effective shooting range, and the large amount of useless information captured will cause the subsequent processing to be unable to be performed automatically, requiring manual intervention
