Description
Technical field
The present invention relates to varifocal imaging field, more particularly, to a kind of varifocal imaging device.
Background technology
With the development of multimedia technology, people begin one's study the video technique with three-dimensional picture so that shoot and
Video there is three-dimensional picture, usual these videos are referred to as 3D videos.At present, the most 3D imaging devices of in the market are used
3D imaging technique be using with parallax left eye object lens and right eye object lens collection image, acquired image is two
It is imaged on individual image sensor chip, such as ccd sensor or cmos sensor, so as to realize that 3D is imaged.However, this imaging
Equipment is provided with two imageing sensors, and its drive circuit uniformity is not high, and bulky due to 3D imaging devices, not side
Portable belt, and 3D imaging device prices are high, and market popularization degree is not high.
Present another 3D imaging devices are by making left eye object lens and right eye object lens collection figure with parallax
Picture, and the scheme that acquired image is imaged on an imageing sensor, this scheme is to be gathered two object lens
Image be respectively formed on an imageing sensor, its volume is greatly reduced.But in present design, due to left and right two
The parallax directions of individual object lens are perpendicular with the line of the central point of the two images for obtaining, and cause to be formed by the imaging device
Image be distorted, and the edge image quality of image is poor, in order to solve this problem, generally requires to use light deflection mechanism
Acquired image is processed with aligning gear.
It can be seen that, in existing technology, either using left eye object lens and right eye object lens with parallax at two
The scheme of 3D imagings is realized on imageing sensor, or by making left eye object lens and right eye object lens with parallax one
The scheme being imaged on individual imageing sensor, all in the presence of inevitable inferior position, such scheme is all unfavorable for the small of 3D imaging devices
Type.
Additionally, people minimize simultaneously in pursuit capture apparatus, it is also desirable to can shoot far and near distance in same position
The image of different objects, and require that the image frame for obtaining becomes apparent from, thus, zoom lens control device arises at the historic moment.By current three
Dimension imaging technique is combined 2 picture sensor chips of needs with optical zoom apparatus, and its drive circuit uniformity is not high, power consumption
Greatly, equipment overall volume is bigger, is not easy to very much the miniaturization of three-dimensional image forming apparatus.It can be seen that, there is provided a kind of focus adjustable and body
The smaller three-dimensional image forming apparatus of product are actually necessary.
The content of the invention
It is an object of the invention to provide a kind of focus adjustable and the smaller varifocal imaging device of volume.
