Zooming method and device of imaging equipment and imaging equipment

Abstract

The invention discloses a zooming method and device of imaging equipment and the imaging equipment. The zooming method comprises the steps: checking whether the current zooming is in a preset opticalzooming region or a preset digital zooming region when the zooming is determined to be carried out; if the target is in the preset optical zoom area, collecting a first image containing a specified target through an image sensor, compressing the first image into a second image and outputting the second image; if so, determining that the zoom lens is in a preset digital zoom area; if so, selectinga target sensing area from the sensing areas of the image sensor; cutting a third image acquired by the image sensor according to the target sensing area to obtain a fourth image, and outputting the fourth image, and the fourth resolution of the fourth image corresponds to the target sensing area, and the visual effect in the digital zooming process is the same as the visual effect of the opticalzooming through the optical zooming and the improved processing mode of the image in the digital zooming process, so that the shooting effect of the imaging equipment is enhanced, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the field of imaging technology, in particular to a zooming method and device for imaging equipment and imaging equipment. Background technique [0002] At present, in order to achieve the zoom effect of the imaging device, a period of digital zoom is added after the imaging device reaches the maximum optical zoom. The imaging device here is, for example, a zoom camera or other devices with a zoom function. [0003] The so-called digital zoom is basically to crop the image obtained by the image sensor, that is, to crop the original picture according to certain rules and output the same resolution as the original image sensor, and then use the corresponding image processing algorithm to convert the cropped picture The area of ​​each pixel is increased to achieve the same resolution as the original picture, which is similar to the enlargement of the picture area by common image processing software. Although the resolutio...

[0003] The so-called digital zoom is basically to crop the image obtained by the image sensor, that is, to crop the original picture according to certain rules and output the same resolution as the original image sensor, and then use the corresponding image processing algorithm to convert the cropped picture The area of ​​each pixel is increased to achieve the same resolution as the original picture, which is similar to the enlargement of the picture area by common image processing software. Although the resolution is still the same, the quality and details of the image have been continuously reduced and Loss, so that at a certain magnification, the image will make people feel that the picture is blurred and distorted
