Problems solved by technology

In addition, the pixel size and photosensitive area of ​​the color sensor in the zoom camera are also small, so it is difficult to reflect more image details in close-up images
Obviously, the above-mentioned shooting process not only reduces the efficiency of close-range imaging, but also reduces the quality of close-range imaging

Embodiment 1

[0068] see figure 1 , figure 1 It is a schematic flowchart of a short-distance imaging method disclosed in an embodiment of the present invention. Such as figure 1 As shown, the method for close-range imaging may include the following steps:

[0069] 101. The mobile terminal receives an enabling instruction for enabling a black and white fixed-focus camera in the mobile terminal.

[0070] In the embodiment of the present invention, the mobile terminal may receive an activation instruction input by the user for enabling the monochrome fixed-focus camera of the mobile terminal, so as to trigger the execution of step 102 . Wherein, the mode of user input can be, clicks on the mobile terminal display screen and is used to open the logo of the monochrome fixed-focus camera of mobile terminal, and the mode of user input can also be, input the voice that is used to open the black-and-white fixed-focus camera of mobile terminal, The embodiments of the present invention are not lim...

Embodiment 2

[0079] see figure 2 , figure 2 It is a schematic flowchart of another short-distance imaging method disclosed in an embodiment of the present invention. Such as figure 2 As shown, the method for close-range imaging may include the following steps:

[0080] 201. The mobile terminal receives an enabling instruction for enabling a black and white fixed-focus camera in the mobile terminal.

[0081] In the embodiment of the present invention, after the mobile terminal receives the start instruction for turning on the black-and-white fixed-focus camera in the mobile terminal, step 202 is triggered to be executed.

[0082] 202. The mobile terminal detects whether the distance between the subject and the black-and-white fixed-focus camera is within the preset clear imaging object distance range. If yes, perform step 208, and if not, perform step 203.

[0083] 203. The mobile terminal detects whether the distance between the subject and the black-and-white fixed-focus camera is ...

Embodiment 3

[0096] see image 3 , image 3 It is a schematic flowchart of another short-distance imaging method disclosed in an embodiment of the present invention. Such as image 3 As shown, the photographed image is a photographed image, and the method for close-range imaging may include the following steps:

[0097] 301. The mobile terminal receives an enabling instruction for enabling a black and white fixed-focus camera in the mobile terminal.

[0098] In the embodiment of the present invention, after step 301 is executed, step 302 is triggered to be executed.

[0099] 302. The mobile terminal detects whether the distance between the object to be photographed and the black-and-white fixed-focus camera is within the preset clear imaging object distance range. If yes, perform step 307, and if not, perform step 303.

[0100] 303. The mobile terminal detects whether the distance between the subject and the black-and-white fixed-focus camera is smaller than the minimum distance of the...

Abstract

The invention discloses a near-distance imaging method and a mobile terminal. The method includes the steps: judging whether a photographed object is in an object distance range capable of clearly imaging by the mobile terminal or not to determine whether a black and white fixed focus camera is started or not; starting the black and white fixed focus camera, and executing shooting operation if thephotographed object is in the object distance range. Under application scenes of near-distance topic shooting, the mobile terminal can present clear topic shooting images in the shortest time according to rapid focusing characteristics of the black and white fixed focus camera, the mobile terminal further present more image details according to the characteristics of large sensing areas and highpixel size of a black and white sensor in the black and white fixed focus camera, so that the quality of black and white images shot by the black and white fixed focus camera is higher than that of acolor image shot by a variable focal camera under the condition of the same sensor size, topic shooting images are conveniently converted into test question contents, and the differentiation degree ofthe topic shooting images is improved. According to the method, near-distance imaging quality and efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a short-distance imaging method and a mobile terminal. Background technique [0002] At present, students can use the zoom camera on the tutoring machine or learning mobile phone to take pictures of the questions at close range, and can retrieve the answers corresponding to the questions taken. In practice, it is found that it takes a long time for students to focus when they use the zoom camera of the tutoring machine or learning mobile phone to take pictures at close range, and the images captured by the zoom camera of the tutoring machine or learning mobile phone are usually color images, so it is still necessary It is necessary to binarize the color image to convert it into a black and white image before performing the search operation. In addition, the pixel size and photosensitive area of ​​the color sensor in the zoom camera are also small, so it is difficult to show mo...
