Embodiment 1

[0029] Such as figure 1 As shown, Embodiment 1 of the present invention provides a horizontal stripe image recognition method based on a mobile terminal, wherein the mobile terminal includes a camera, and the method includes:

[0030] Step 101. Acquire a frame of preview image captured by the camera.

[0031] Firstly, the camera of the mobile terminal is used to collect a frame of preview image, where the mobile terminal can be a camera, a smart phone, a tablet computer, and a PAD.

[0032] Step 102, performing binarization processing on each pixel of the preview image to generate an intermediate image.

[0033] The obtained preview image is analyzed to obtain each pixel of the preview image. The concept of a pixel is: in a digital image, the image is divided into very small points, and the small points formed here are called pixels, and each pixel corresponds to a gray value representing the brightness of the image at that point. Then, binary processing is performed on eac...

Embodiment 2

[0045] Such as figure 2 As shown, Embodiment 2 of the present invention provides a horizontal stripe image recognition method based on a mobile terminal, wherein the mobile terminal includes a camera, and the method includes:

[0046] Step 201. Acquire a frame of preview image captured by the camera.

[0047] Firstly, the camera of the mobile terminal is used to collect a frame of preview image, where the mobile terminal can be a camera, a smart phone, a tablet computer, and a PAD. The preview image obtained at this time is an unprocessed image, and the gray value of the pixel is relatively complex. Therefore, step 202 needs to be executed after the preview image is obtained.

[0048] Step 202, performing binarization processing on each pixel of the preview image to generate an intermediate image.

[0049] After a frame of unprocessed preview image is collected by the camera, each pixel in the preview image is processed by a binarization method, and an intermediate image i...

Embodiment 3

[0096] Such as image 3 As shown, Embodiment 3 of the present invention provides a mobile terminal-based horizontal stripe image recognition method, wherein the mobile terminal includes a camera, and the method includes:

[0097] Step 301. Acquire a frame of preview image captured by the camera.

[0098] Firstly, the camera of the mobile terminal is used to collect a frame of preview image, where the mobile terminal can be a camera, a smart phone, a tablet computer, and a PAD. The preview image obtained at this time is an unprocessed image, and the gray value of the pixel is relatively complex. Therefore, step 302 needs to be executed after the preview image is obtained.

[0099] Step 302, performing binarization processing on each pixel of the preview image to generate an intermediate image.

[0100] After a frame of unprocessed preview image is collected by the camera, each pixel in the preview image is processed by a binarization method, and an intermediate image is gene...

Abstract

The present invention provides a mobile terminal-based horizontal stripe image recognition method and the mobile terminal, wherein the mobile terminal includes a camera, and the mobile terminal-based horizontal stripe image recognition method includes: acquiring a frame of preview image collected by the camera; Each pixel is binarized to generate an intermediate image; according to the intermediate image, determine the gray value change information of the pixel in the intermediate image; according to the gray value change information of the pixel in the intermediate image, identify whether the preview image is horizontal Striped image. The method provided by the embodiment of the present invention can quickly detect whether the current image is a horizontal stripe image through simple processing, maximize time efficiency and reduce power consumption, and solve the problem that the phase detection autofocus sensor cannot recognize the horizontal stripe image , leading to the problem of not being able to focus on scenes with horizontal stripes.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a mobile terminal-based horizontal stripe image recognition method and a mobile terminal. Background technique [0002] With the development of image processing technology, most mobile terminals have increasingly diversified camera functions, such as camera filters, focus tracking and other functions. In daily life, mobile terminal users often encounter shooting scenes with horizontal stripes in the process of taking pictures. [0003] At present, for the shooting scene of horizontal stripes, during the shooting process, for the sensor of phase detection auto-focus, since the image of horizontal stripes cannot be recognized, the scene of horizontal stripes cannot be focused. Contents of the invention [0004] Embodiments of the present invention provide a horizontal stripe image recognition method based on a mobile terminal and the mobile terminal to solve the problem...
