Abstract

The invention discloses an image pickup device of handheld equipment. The image pickup device comprises an image pickup module, a signal processing module and a judging and selecting module, wherein the signal processing module is used for performing signal processing on data output by the image pickup module; the image pickup module comprises at least two cameras which correspond to different focal distances; and the judging and selecting module is used for judging imaging definition and selecting one clearly-imaged picture for displaying. According to the image pickup device, a zooming video pickup function of the handheld equipment can be realized under the condition of not increasing the thickness of the handheld equipment, a product meets the requirements of small size, light weight and high performance, and the competition of the product is improved.

Description

A kind of camera head of handheld device

Technical field

The present invention relates to a kind of camera head, more particularly, is a kind of camera head of handheld device.

Background technology

In existing cell phone cameras design, generally only support a kind of photograph of focal length, be commonly called as the fool and take a picture, in high-grade mobile phone, the adding zoom lens is arranged also, support the mobile phone camera design of different focal, there are following two shortcomings in this kind camera design:

1) cost is higher, and this causes owing to introducing Varifocal pick-up lens.

2) this kind mobile phone volume is bigger, because zoom lens needs more optics and stepping motor, so volume is bigger.

Summary of the invention

In order to solve the problems referred to above that prior art exists, the present invention proposes a kind of camera head of handheld device, and it is not increase on handheld device volume and the handheld device design difficulty basis, making handheld device have the device of varifocal camera function.

The present invention can be solved by the following technical programs:

A kind of camera head of handheld device, comprise photographing module, described photographing module dateout carried out the signal processing module of signal processing, described photographing module comprises at least 2 cameras, the focal length that each camera is corresponding different, comprise that also the differentiation that the definition of a pair of imaging is differentiated selects module, select one of them imaging clearly picture show.

Camera of the present invention is 2, the focal length of the corresponding 0-1 rice of one of them camera, the corresponding focal length more than 1 meter of another camera.

Owing to adopt above technical scheme, the camera head of a kind of handheld device of the present invention, can under the situation that does not increase the handheld device volume, make handheld device have the zoom camera function, as supporting microspur shooting (0-1 rice simultaneously, take low coverage article such as business card) and common distance shooting (scenery as taking is more than 1 meter).The present invention can promote the performance and the user experience of cell-phone camera greatly, thereby improves competitiveness of product, creates the profit of annual millions of dollar.

Fig. 2 is a picture rich in detail output flow chart of the present invention.

1 photographing module among the figure; 2 signal processing modules; 3 differentiate the selection module

Embodiment

Below in conjunction with embodiment, further set forth the present invention:

As shown in Figure 1, a kind of camera head of handheld device, comprise photographing module 1, photographing module 1 dateout carried out the signal processing module 2 of signal processing, photographing module 1 comprises at least 2 cameras, the focal length that each camera is corresponding different, comprise that also the differentiation that the definition of a pair of imaging is differentiated selects module 3, it selects one of them imaging distinct image to export.

Camera of the present invention is 2, the focal length of the corresponding 0-1 rice of one of them camera, and the corresponding focal length more than 1 meter of another camera, camera can be selected the camera of the focal length of needs as required certainly.

When camera was 2, concrete image output flow process as shown in Figure 2.2 cameras pickup image respectively obtain Fig. 1 and Fig. 2, and Fig. 1 and Fig. 2 be input to signal processing module 2, obtain estimated value to image definition, after treatment Fig. 1 and Fig. 2 being input to differentiate selects module 3 to differentiate, judge whether Fig. 1 is more clear than Fig. 2, if output and displayed map 1 are then exported and displayed map 2 if not.

But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.

Claims

1. the camera head of a handheld device, comprise photographing module, described photographing module dateout carried out the signal processing module of signal processing, it is characterized in that: described photographing module comprises at least 2 cameras, the focal length that each camera is corresponding different, comprise that also the differentiation that the definition of a pair of imaging is differentiated selects module, select one of them imaging clearly picture show.

2. the camera head of a kind of handheld device according to claim 1, it is characterized in that: described camera is 2, the focal length of the corresponding 0-1 rice of one of them camera, the corresponding focal length more than 1 meter of another camera.
