Embodiment Construction
[0036] In order to further illustrate the image acquisition method and the image acquisition device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.
[0037] The image acquisition method provided by the embodiment of the present invention is applied to a terminal device, and the terminal device generally includes a laser sensor and a camera device disposed on the same side. The inventors of the present application have found through research that during the shooting process of using the terminal device, the laser sensor will emit a laser for assisting focusing, and the laser is in a state of flickering when emitting, but the flickering frequency has exceeded beyond the range that the human eye can distinguish. Although the flicker frequency of the laser is very high, according to the characteristics of the camera device that can output high frame rate images, it is still possible to ...

The invention discloses an image acquisition method and an image acquisition device, and relates to the technical field of image processing. The image acquisition method and the image acquisition device are aimed to solve the problem that laser points display on a glass back cover for covering a laser sensor in a photograph, which affects user experience. The image acquisition method includes thefollowing steps: acquiring first image data and second image data of a target shot object; determining position information of the laser points mapped in the first image data by a laser emitted by thelaser sensor and pixel information of a pixel region corresponding to the position information when the laser is extinguished through the second image data; processing the first image data accordingto the position information and the pixel information of the pixel region corresponding to the position information when the laser is extinguished to obtain target image data; and generating a targetimage whose laser points are eliminated according to the target image data. The image acquisition method provided by the invention is used for acquiring an image of a target shot object.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image acquisition method and an image acquisition device. Background technique [0002] The laser sensor is a sensor that uses laser technology for distance measurement. It is widely used in the field of focusing because of its advantages such as fast measurement speed, high precision, and strong anti-interference ability. The laser beam emitted by the laser sensor is an invisible light with a wavelength of about 940 nanometers. When the laser beam irradiates the lens of the camera, due to the low quality of the lens, the invisible light of 940 nanometers cannot be filtered out, so that the laser beam can be detected. The camera captures the laser dots on the glass rear shell used to cover the laser sensor in the photos taken, which affects the user experience. [0003] In order to eliminate the laser spot on the photo, the following two methods are generally...
