Embodiment 1

[0055] see figure 1, an embodiment of the present invention provides a method for acquiring an iris image, the method comprising:

[0056] Step 101: The electronic device acquires the selected usage mode of the dual cameras, and the first camera and the second camera of the electronic device are located on the same side of the electronic device.

[0057] Step 102 : when the use mode is the iris mode, turn on any one of the first camera and the second camera to take a first facial picture, where the first facial picture includes an eye image.

[0058] Step 103: Remove the color information of each pixel in the first facial image and retain the luminance information of each pixel to obtain a second facial image.

[0059] Step 104: Extract the eye image in the second facial picture and determine the eye image as the iris image.

[0060] In the embodiment of the present invention, the selected usage mode is acquired, and when the usage mode is the iris mode, the first facial ima...

Embodiment 2

[0062] see Figure 2-1 , an embodiment of the present invention provides a method for acquiring an iris image, including:

[0063] Step 201 : the electronic device acquires the selected usage mode, and the usage modes include an iris mode and a dual-camera mode.

[0064] The electronic device can be a mobile phone, a tablet computer, or a notebook computer, etc. The electronic device includes a first camera and a second camera. The first camera and the second camera are located on the same side of the electronic device, and neither is an iris camera Both are ordinary cameras used to take pictures.

[0065] The electronic device defines two usage modes, iris mode and dual-camera mode. see Figure 2-2 , when the user activates the camera included in the electronic device, the electronic device displays an activation interface, which includes a first trigger interface corresponding to the iris mode and a second trigger interface corresponding to the dual-camera mode. If the u...

Embodiment 3

[0111] see image 3 , an embodiment of the present invention provides an apparatus 300 for acquiring an iris image, the apparatus 300 includes:

[0112] The obtaining module 301 is used to obtain the selected use mode of the dual cameras of the electronic device, and the first camera and the second camera of the electronic device are located on the same surface of the electronic device; when the use mode is the iris mode, Turn on any camera in the first camera and the second camera, and take a first facial picture, where the first facial picture includes an eye image;

[0113] Removing module 302, for removing the color information of each pixel in the first facial picture and retaining the brightness information of each pixel to obtain the second facial picture;

[0114] The extraction module 303 is configured to extract the eye image in the second facial picture and determine the eye image as an iris image.

[0115] Optionally, the electronic device includes a first camera...

Abstract

The present invention discloses a method and device for obtaining iris images, belonging to the communication fields. The method comprises: an electronic device obtains a usage mode selected by a dual camera, the first camera and the second camera of the electronic device are located at the same surface of the electronic device; when the usage mode is an iris mode, any one of the first camera and the second camera is turned on to shoot a first face image, wherein the first face image comprises an eye image; the color information of each pixel point in the first face image is removed and the brightness information of each pixel is kept to obtain a second face image; and the eye image in the second face image is extracted to determine that the eye image is an iris image. The device comprises an obtaining module, a removal module and an extraction module. The method and device for obtaining iris images can allow the electronic device to realize the dual camera technology and can realize the iris identification technology.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for acquiring an iris image. Background technique [0002] The use of dual-camera technology in mobile phones has gradually formed a trend. The so-called dual-camera technology refers to setting two cameras on the front and / or back of the mobile phone, and using the two cameras set on the front or back of the mobile phone to take pictures of the same object, and the two cameras obtained from the pictures are taken. The images are combined into one high-definition image. [0003] Since there is not enough space to set other cameras after the two cameras set on the front or the back of the phone, other technologies cannot be implemented using the other cameras, such as iris recognition technology. SUMMARY OF THE INVENTION [0004] In order to enable the electronic device to realize both the dual camera technology and the iris recognition technology,...
