Data input pen with photographing function and photographing range laser positioning method thereof

Abstract

The invention discloses a data input pen with a photographing function and a photographing range laser positioning method thereof. The data input pen comprises a camera, a laser emitter and a gratinglens, wherein the laser emitter is matched with the grating lens, when the laser emitter emits a laser beam, the laser beam penetrates through the grating lens to form a marking picture frame, the laser emitter and the camera are both arranged to face a photographed object, and the photographing ranges of the marking picture frame and the camera are at least partially overlapped on the plane of the photographed object. The scanning pen solves the problem that an existing scanning pen can only perform near-scene scanning but cannot perform far-scene photographing. The data input pen is not provided with a display screen for a photographer to effectively select the photographing range, so that the photographing range is identified by using the cursor range through a method of laser markingand actual photographing range coincidence by using a technical means, and the photographer can effectively select the photographing range according to the cursor identification range so as to accurately photograph the photographing range.

Description

technical field [0001] The invention relates to the field of computer peripheral input devices, in particular to a data entry pen with a camera function. Background technique [0002] Scanning pens currently on the market can only scan and input text at close range (close to the paper surface). If you want to input larger image information, you need to scan the image multiple times in staggered lines, and then recombine it. The picture synthesis effect cannot be guaranteed at all, and the real restoration cannot be achieved, and the picture information entry requirements cannot be met. [0003] The existing scanning pen does not have the function of taking photos at a relatively long distance, and it is also impossible to effectively select and locate the range of photos taken. [0004] Since the existing scanning pen does not have the function of taking pictures at a longer distance, it certainly does not have the function of supplementing light for taking pictures. Cont...

AI Technical Summary

Problems solved by technology

The picture synthesis effect cannot be guaranteed at all, and the real restoration cannot be achieved, and the picture information entry requirements cannot be met.

[0003] The existing scanning pen does not have the function of taking pictures at a longer distance, nor can it realize the effective selection and positioning of the shooting range

[0004] Since the existing scanning pen does not have a long-distance camera function, of course there is no camera fill light function
