Description

Device of single camera controller of two cameras

Technical Field

The utility model relates to an image recognition field especially indicates a device of two single camera shooting controllers of making a video recording.

Background

Nowadays, the era of image-keeping at any time, along with the progress of science and technology, more and more biological recognition-based technologies are applied to the daily life of people. For example, the face recognition technology is applied to attendance machines, face payment, intelligent locks based on face recognition and the like. More and more face recognition technologies provide better experience for users and more convenient service. As basic equipment of the face recognition technology: dual cameras are increasingly being provided in mobile or non-mobile terminals.

In order to facilitate face recognition, one of the two cameras is a black-and-white camera, and the other one of the two cameras is a color camera. Whether the image of the face is a live face can be judged based on the feature values extracted by the two cameras. And the two cameras on the current market are mostly in a one-to-one mode that one camera corresponds to one camera controller. And the selection range of manufacturers is small, and the price is high.

SUMMERY OF THE UTILITY MODEL

In view of the need for cost control, it is an object of the present invention to provide a dual camera single camera controller device. The camera controller in one CPU can control two cameras to work. The cost is saved, and the technical effect that the two cameras can work is achieved.

Based on above-mentioned purpose the utility model provides a pair of single camera controller's of two cameras device, include: the camera comprises a first camera module, a second camera module and a camera controller; the camera shooting controller is arranged in the CPU and is connected with the first camera module and the second camera module through a data line, a clock line and an MCLK line; and the CPU is provided with at least one IIC interface which is connected with the first camera module and the second camera module.

The resolution ratios of the cameras in the first camera module group and the cameras in the second camera module group are the same.

The CPU is provided with a buffer area for storing the data collected by the first camera module and the second camera module.

And the camera module sends the acquired data to a buffer pool of the CPU through a data line.

The data line and the clock line are at least one.

The at least one IIC interface comprises a first IIC interface and a second IIC interface, when the CPU comprises the first IIC interface and the second IIC interface, the first IIC interface is connected with the first camera module, and the second IIC interface is connected with the second camera module.

When only one IIC interface is provided, the IIC is provided with an address, the first camera is provided with a first IIC address, and the second camera is provided with a second IIC address, so that interface communication is carried out.

And when only one IIC interface is provided, a switch is arranged at the IIC interface.

And also comprises a data storage external device.

An external power supply device is also included.

From the foregoing, the utility model provides a pair of make a video recording single camera controller's device links together the data line of two cameras, control line and is connected with the camera control. The two cameras respectively send the data collected by the cameras to the controller in a time-sharing multiplexing mode. Therefore, the optional range of the CPU is greatly increased, the cost can be greatly reduced, and the technical effect that the double cameras can work is achieved.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is the device structure schematic diagram of the embodiment of the utility model discloses a two cameras single control wares.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.

The examples of the application are as follows:

an apparatus of a dual camera single camera controller, comprising: the camera comprises a first camera module, a second camera module and a camera controller; the camera shooting controller is arranged in the CPU and is connected with the first camera module and the second camera module through a data line, a clock line and an MCLK line; and at least 1 IIC interface on the CPU is connected with the first camera module and the second camera module.

The resolution ratios of the two cameras must be the same between the camera in the first camera module group and the camera in the second camera module group.

The data line and the clock line are at least one.

When the CPU comprises a first IIC interface and a second IIC interface, the first IIC interface is connected with the first camera module, and the second IIC interface is connected with the second camera module.

And when only one IIC interface is provided, a switch is arranged at the IIC interface and used for controlling the interface.

The apparatus may further comprise a data storage peripheral for storing the relevant data.

The apparatus may further comprise an external power supply device for supplying power.

Because a camera controller is used, the resolution of the first camera and the resolution of the second camera must be the same, otherwise, effective data cannot be acquired. If the IIC addresses of the two cameras are different, the IIC-1 and the IIC-2 can also use one IIC controller, and the first camera and the second camera can be distinguished through the addresses.

The time division multiplexing mode can also be realized by switching a switch.
