Novel three-dimensional image shooting module

Abstract

The invention relates to a novel three-dimensional image shooting module which can achieve synchronous focusing control over portable electronic product dual lens or multiple lens and three-dimensional image shooting. The module comprises a plurality of camera modules fixed on a voice coil motor, the voice coil motor which can bear the camera modules at the same time, an image sensor which is used for collecting shot image information, a control circuit and back end processing software which can carry out grey level weighting and three-dimensional image synthesis. The camera modules have the same parameters and are borne on the same voice coil motor, synchronous focusing can be carried out, the number of the image sensor can be one or more, the back end processing software carries out weighting according to a preset factor through the grey levels of two images during a focusing process, and feedback fine focusing is carried out after a comprehensive grey level is obtained. The shooting module can be used on a micromation portable electronic product conveniently for three-dimensional image shooting, and quality and shooting effect can be improved.

Description

technical field [0001] The invention relates to a novel three-dimensional image shooting module, which can realize dual-lens or multi-lens synchronous focusing control and three-dimensional image shooting of portable electronic products. Background technique [0002] In recent years, with the prosperity of the 3D market, the general public has more and more interest in shooting 3D images and videos, which puts forward higher requirements for the miniaturization, portability and low cost of 3D shooting modules. At present, digital devices on the market basically have the function of shooting two-dimensional images and videos. The price of products with dual-camera three-dimensional shooting function is relatively high, and the control circuit is complicated, which increases the internal structure. trend is contrary. Therefore, it is necessary to shorten the distance between the two cameras and simplify the structure of the three-dimensional shooting module. [0003] At pres...

Problems solved by technology

[0010] According to the existing technology, the combination mode of dual lens and double voice coil motor is adopted to realize the three-dimensional shooting function. This mode makes the overall shooting module too large, which is not conducive to the miniaturization and portability of electronic products. It is applied to portable electronic devices such as mobile phones. When the product is put on, it not only increases the quality and volume of the product, but also is not conducive to the appearance

[0011] Another disadvantage is that the use of dual-lens dual-voice coil motors requires two control signals to drive the voice coil motors separately, which will complicate the control mechanism and the corresponding control circuit, and also increase the complexity of equipment installation. Not conducive to cost reduction

[0012] Another disadvantage is that due to the existence of unfavorable factors such as manufacturing and assembly errors, errors in the control system, and signal interference, the dual voice coil motors drive their respective lenses, which is not conducive to the synchronous action between the two lenses and affects the focal length of the two lenses. Alignment, so that the images captured by the two lenses may be images at different focal lengths, which will not only affect the clarity of the image, but the error of the obtained parallax information will also affect the composition of the back-end 3D 3D image, reducing the image capture quality

[0013] Another disadvantage is that the combination mode of dual-lens and dual-voice coil motors has higher requirements on the anti-shake function of the voice coil motors.
