Dynamic zoom method, device and intelligent device

Abstract

The embodiment of the invention provides a dynamic zoom method, device and intelligent device, wherein the method comprises following steps of starting at least two cameras; obtaining preview images; carrying out initial focus on the photographing devices; dynamically obtaining at least two parts of image data by the at least two cameras repeatedly as the distances between the photographed objects and the photographing devices are changed dynamically; analyzing the at least two parts of image data obtained at the same moment, thus obtaining depth information; comparing the latest depth information with the former depth information; analyzing; determining zoom times; and focusing the photographing devices according to the determined zoom times. Visibly, according to the method, the device and the terminal, the depth information of the images is obtained by taking the advantages of the multiple cameras; when a user uses an amplification function, the distances between the photographing devices and the photographed objects can be actively detected, the corresponding zoom times is set, and the sizes of the objects displayed in the images are stable and are beneficial for the user to check.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a dynamic zoom method, device and intelligent terminal. Background technique [0002] Photographic technology continues to evolve. The earliest camera structure is very simple, only including camera obscura, lens and photosensitive material. Modern cameras are relatively complex, with systems such as lens, aperture, shutter, distance measurement, viewfinder, light metering, film feeding, counting, Selfie, focusing, and zooming. Modern cameras are a combination of optics, precision machinery, electronic technology and chemical technology. complex equipment. A digital camera is a camera that uses an electronic sensor to convert optical images into electronic data. Unlike traditional cameras that record images on film by chemical changes in silver bromide, the sensor of a digital camera is a light-sensitive sensor. Charge-coupled (CCD) or complementary metal-oxide-semi...

Problems solved by technology

For example, when the user selects 2x zoom, as the user moves away from or approaches the subject, the size of the subject on the screen will also change, which is not conducive to the user's stable viewing of the image.
