Description

Camera module

Technical Field

The utility model relates to a camera image acquisition technical field particularly, relates to a camera module.

Background

A digital camera is a camera that converts an optical image into electronic data using an electronic sensor. It integrates the components of image information conversion, storage and transmission, etc. and is a product integrating optics, mechanics and electronics. Digital cameras were first introduced in the united states, which was used to transmit photographs to the ground via satellite decades ago, and later turned into civilian use and continued to expand the range of applications. Today, the shadow of a digital camera is seen everywhere in various fields such as traffic, security, industrial manufacturing, consumer electronics and the like, and the technical progress is very rapid. Particularly in the field of consumer electronics, products supporting wide-angle photographing and high-power optical zoom capability have been developed in recent years.

In order to realize wide-angle photographing by a digital camera, there are four common schemes: 1. the direct use of a large-size wide-angle lens is a common solution in professional single lens reflex cameras. However, the solution is large in size and high in cost, and cannot be used in products with limited cost or size; 2. the use of the fisheye lens is limited by the optical properties of the fisheye lens, the scheme has low cost, but the imaging is distorted (the distortion can be corrected by software), and the imaging quality is not high. So most of them are applied to low-cost monitors; 3. the camera needs to be translated when the scheme is used for shooting, a plurality of photos need to be continuously shot, the software is reused to splice a wide-angle picture, the scheme is commonly used for satellite shooting and photo processing, and the function of product integration is realized in the field of consumer electronics. However, the translation of the camera needs to be smooth and is only suitable for shooting a static scene, and the scheme cannot be used for shooting a moving picture; 4. the multi-camera scheme is popular in the field of smart phones today, multiple pictures are shot simultaneously by the aid of the multiple cameras, and then the wide-angle shooting effect can be achieved by means of software synthesis and splicing, as shown in fig. 3.

Therefore, compared with scheme 1, scheme 4 does not use a large-size wide-angle optical lens, and has controllable cost and light volume; compared with the scheme 2, the scheme 4 has no image distortion and good imaging quality; compared with the scheme 3, the scheme 4 can directly and quickly obtain a plurality of photos before synthesis without moving a camera, and is not limited to only shooting a static scene. But the implementation of scheme 4 relies on a plurality of cameras, and the increase of camera quantity can be on the one hand drawn high cost, and on the other hand the quality between a plurality of cameras, technical parameter is difficult to accomplish unanimously. Therefore, the original photo before synthesis has color difference and needs software correction. The scheme stated in the disclosure is most similar to the above 4 th scheme, and has the advantages of the scheme 4 compared with the schemes 1-3, meanwhile, the dependence of the scheme 4 on a plurality of cameras is improved, and the cost problem and the imaging chromatic aberration problem of the plurality of cameras are eliminated.

An effective solution to the problems in the related art has not been proposed yet.
