Abstract

The invention provides a professional notebook computer facilitating electronization and an electronic thumbnail photo display method thereof. The method comprises shooting a paper page image facilitating the electronization for the professional notebook computer, conforming a paper page type according to the paper page image to obtain position, on a paper page, of a title area printed on the paper page of the professional notebook computer, conforming four edge lines of the paper page image through a straight line detection method of the image and correcting a page area defined by the four edge lines to a square area to decide the accurate position of the title area in the square area, judging whether the title area is blank or not and extracting content of the title area to generate a thumbnail photo of the paper page image if the title area is not blank. According to the facts that the title area is printed on the paper page of the notebook computer and the title area is automatically segmented to be the thumbnail photo of an electronic file in the process electrolization of a notebook page by utility software of Cam Scanner and the like, management and inquiry of the electronic files is facilitated.

Description

A kind of professional notebook and electronics method for viewing thumbnail thereof of convenient electronization
Technical field
The invention belongs to the electronic computer technology field, relate to a kind of display packing of electronic document, particularly relate to a kind of professional notebook and electronics method for viewing thumbnail thereof of convenient electronization.
Background technology
In daily life, people often need to take paper document, preserve into the photo of jpeg format, perhaps generate the document of PDF, thereby realize the electronization of paper document, convenient management.Smart mobile phone be exactly commonly use with one of instrument of paper document electronization.Because generally all with camera, utilize the camera on the mobile phone can take paper document on the smart mobile phone, and the electronic document that shooting obtains carried out converting to after certain image is processed the photo of jpeg format again, perhaps generate the document of PDF.The application software that possesses above-mentioned functions is also more universal, such as the application CamScanner in apple application shop and the google application shop.These application software can be from the image of taking automatic monitoring measure the four edges of captured document, excise the background of document areas outside in the image as benchmark, and document areas proofreaied and correct and the processing such as figure image intensifying, obtain an effect that is similar to the shipshape electronic document that obtains with scanner scanning, preserve and manage with the form of user's appointment.
The paper document that common needs carry out electronization is the paper spare notebook page, people did various records originally through the notes of common paper part for a long time, such as minutes, memorandum transaction record etc., have dozens or even hundreds of page or leaf paper in the paper spare notebook, and the notebook of same type, the pattern of its all pages that are used for recording generally is unified.With application software such as CamScanner the notebook page is carried out electronization, with the form of the form of jpeg image or PDF document be saved in go in the electronic equipments such as smart mobile phone after, what people saw on the display screen of the electronic equipments such as smart mobile phone generally is the thumbnail of electronic document, clicks and opens the full content that thumbnail just can be seen later on electronic document.Just look like in the PC of windows operating system computing machine, people can preserve certain the image of the file the inside of image file and list with the form of thumbnail, see first a general picture of each image file by thumbnail, click this thumbnail and open the full content that this file just can be seen later on the file the inside.For figure, thumbnail is the general picture of display graphics clearly, but for literal, the literal that shows in the thumbnail is very little, be directly to tell wherein general content, what do not see probably from the thumbnail that whole the page obtains namely that each notebook page records is any content.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of professional notebook and electronics method for viewing thumbnail thereof of convenient electronization, content confused for the papery page after the solution prior art electronization is difficult for realizing the management of content and the problem of inquiry.
Reach for achieving the above object other relevant purposes, the invention provides a kind of professional notebook and electronics method for viewing thumbnail thereof of convenient electronization.
A kind of professional notebook of convenient electronization is printed with for the Title area of summing up this content of pages on the papery page of the professional notebook of described convenient electronization.
Preferably, described Title area comprises the main title zone or/and subtitle is regional.
Preferably, described Title area is fixed at the assigned address on the described papery page.
A kind of electronics method for viewing thumbnail of professional notebook of convenient electronization, the method comprises:
Take the papery page-images of the professional notebook of convenient electronization;
