Abstract

The present invention provides an image acquisition terminal, which includes a first camera module, a second camera module and a processing module, the first camera module and the second camera module are used to simultaneously view the same scene, and the first camera The resolution of the output image of the module is greater than the resolution of the output image of the second camera module, the processing module detects and analyzes according to the contrast of different frame images, controls the second camera module to automatically focus and determine the focus point, and the processing module The module is also used to determine the focus point of the first camera module according to the focus point information of the second camera module, control the first camera module to directly focus according to the determined focus point, and acquire an image at the focus point. The present invention also provides an image acquisition method correspondingly. The invention can solve the problem of slow focus of the existing single-lens image acquisition module using high-resolution output images.

Description

technical field [0001] The present invention relates to the field of terminal shooting, and in particular to an image acquisition terminal and an image acquisition method capable of fast focusing. Background technique [0002] Auto Focus (Auto Focus) is to use the principle of object light reflection, the reflected light is received by the sensor CCD on the camera, and the method of driving the electric focusing device to focus through computer processing is called auto focus. Contrast method for focusing is to achieve automatic focus by detecting the contour edge of the image. The sharper the edge of the outline of the image, the greater its brightness gradient, or the greater the contrast between the scene and the background at the edge. Conversely, for an out-of-focus image, the contour edge is blurred, and the brightness gradient or contrast decreases; the farther out of focus, the lower the contrast. [0003] In the existing single-camera focusing system, the automati...
