Embodiment 1

[0070] An embodiment of the present invention provides a mobile terminal. image 3 It is a schematic diagram of the composition and structure of the mobile terminal according to the embodiment of the present invention; image 3 As shown, the mobile terminal includes: an image acquisition unit 31, an image processing unit 32 and a determination unit 33; wherein,

[0071] The image acquisition unit 31 is configured to acquire a first image, and send the first image to the image processing unit 32; the image acquisition area corresponding to the first image has uniform brightness and the brightness parameter meets a preset threshold;

[0072] The image processing unit 32 is configured to divide the first image into N×M regions, and obtain the average gray level of each region; N and M are both positive integers;

[0073] The determination unit 33 is configured to calculate the difference between the average gray levels of the first area and the second area, and determine whether...

Embodiment 2

[0083] The embodiment of the present invention also provides a mobile terminal, for details, please refer to image 3 As shown, the mobile terminal includes: an image acquisition unit 31, an image processing unit 32 and a determination unit 33; wherein,

[0084] The image acquisition unit 31 is configured to acquire a first image, and send the first image to the image processing unit 32; the image acquisition area corresponding to the first image has uniform brightness and the brightness parameter meets a preset threshold;

[0085] The image processing unit 32 is configured to divide the first image into N×M regions, and obtain the average gray value of each region; N and M are both positive integers; wherein, the first region A m，n and the second area A m-2， n between the third area A in the horizontal direction m-1，n ; or, the first area A m，n and the second area A m， n-2 Between vertically separated by the third area A m，n-1 ; Wherein, both m and n are positive integ...

Embodiment 3

[0099] The embodiment of the present invention also provides an information processing method. Figure 7 It is a schematic flow chart of the first information processing method of the embodiment of the present invention; as Figure 7 As shown, the method includes:

[0100] Step 501: Acquire a first image; the image acquisition area corresponding to the first image has uniform brightness and a brightness parameter meets a preset threshold.

[0101] In this embodiment, the user controls the image acquisition area of ​​the image acquisition unit of the mobile terminal to be an area with uniform brightness and whose brightness parameter meets a preset threshold. As an implementation mode, a uniform light plate is preset, and the uniform light plate has a fixed light-emitting area, such as a rectangular light-emitting area (such as Figure 4 shown); the uniform light panel can emit light with uniform brightness properties in its fixed light-emitting area, that is, the brightness ...

Abstract

The embodiment of the invention discloses a mobile terminal and an information processing method. The mobile terminal comprises an image acquisition unit used for acquiring a first image and sending the first image to an image processing unit; the image processing unit used for dividing the first image into N*M regions and obtaining an average grey value of each region, wherein N and M are positive integers; and a judging and determining unit used for calculating a difference value of the average grey values of a first region and a second region, judging whether the difference value of the average grey values of the first region and the second region is greater than a first threshold value, obtaining a judgment result, and determining that a first sub-region of the image acquisition unit of the mobile terminal corresponding to the first region is in an abnormal state or a second sub-region of the image acquisition unit of the mobile terminal corresponding to the second region is in the abnormal state when the judgment result shows that the difference value of the average grey values of the first region and the second region is greater than the first threshold value.

Description

technical field [0001] The present invention relates to information processing technology, in particular to a mobile terminal and an information processing method. Background technique [0002] The mobile terminal lens module is mainly composed of lenses and Complementary Metal Oxide Semiconductor (CMOS, Complementary Metal Oxide Semiconductor) sensors (Sensor). During the process of assembling the lens module to the mobile terminal, due to the influence of operating conditions, blurred screens and dirty screens may occur. pollution etc. The specific manifestation is that color blocks, black spots, or black stripes appear on the captured image of the mobile terminal. In the prior art, the mobile terminal takes a photo of the uniform light plate and then transmits the image to the computer, and then enlarges the image on the computer to check the dirtiness of the picture with the naked eye, so as to know whether the lens module is blurred or dirty. And other issues. This d...
