Title:
IMAGE ZOOMING PROCESSING METHOD, DEVICE, AND TERMINAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/018930
Kind Code:
A1
Abstract:
Provided in the present application are an image zooming processing method, device, and terminal apparatus. The method comprises: performing detection on a user zooming operation on an original preview image acquired by a terminal apparatus at an initial position, and determining a zooming ratio and a region to be magnified; triggering a microelectromechanical system to move, according to a predetermined displacement distance corresponding to the zooming ratio, an image sensor to reference positions corresponding to multiple directions, and acquiring, at the multiple reference positions, corresponding reference preview images respectively; superimposing reference pixels of the reference preview images corresponding to the region to be magnified and original pixels corresponding to the region to be magnified in the original preview image to acquire synthesized pixels corresponding to the region to be magnified; and performing, according to the size of the original preview image, zooming and magnification processing on the synthesized pixels. In this way, the present invention enables, by employing a microelectromechanical system to control an accurate and rapid movement of an image sensor, zooming and magnifying processing, thus increasing the number of pixels in a region to be magnified, and accordingly improving image quality of the region to be magnified.
