Photographic correction method and photographic apparatus for a multi-lens group

Abstract

The invention relates to a photographing correction method and a photographing device of a multi-lens group, comprising: S1. enabling one lens group in the multi-lens group to capture a first image and generating a first sharpness index based on the first image; S2, judging whether the first sharpness index satisfies a preset first threshold condition, if not, enabling another lens group in the multi-lens group to capture a second image; S3. acquiring the number of pixels added to the first image by the second image based on the first sharpness index, and completing correction of the first image. Based on the sharpness index to evaluate whether the first lens composition image is blurred, When part or all of the first image is blurred, a second lens with a focus range different from that of the first lens group is enabled to photograph the second image, and the blurred area in the first image is replaced or synthesized through the second image, thereby greatly reducing the calculationamount and improving the calculation efficiency under the condition of guaranteeing the image quality.

Description

technical field [0001] The invention relates to the field of optical lens imaging, in particular to a photography correction method and photography device of a multi-camera lens group. Background technique [0002] In recent years, with the development of science and technology, portable electronic products such as mobile phones and tablet computers have gradually emerged, and portable electronic products with camera functions have been more favored by people. Therefore, the market demand for camera lenses suitable for portable electronic products has gradually increased. big. However, as portable electronic products tend to be miniaturized and thinner, the overall length of the lens is limited, thereby increasing the difficulty of lens design. At the same time, with the improvement of the performance and the reduction of the size of commonly used photosensitive elements such as CCD (Charge-Coupled Device) or CMOS (Complementary Metal-Oxide Semiconductor, complementary meta...

Problems solved by technology

However, the application of the two lenses in the existing technology is still not perfect, and there are still various usage scenarios that can be realized through the dual-camera lens waiting to be explored

In particular, it is difficult for a dual-camera lens group to achieve dynamic zooming. Instead, it is often necessary to simulate the zoom effect by software means by fusing the images taken by the two lens groups, which leads to the sharpness of the images captured by the existing dual-camera module. low, poor performance
