Multi Functional Digital Dual Camera

The present invention relates to a multi-function digital dual camera, and more specifically, to capture stills, video and audio by integrating digital camera function, PC camera function, and voice recording function, and to store and edit the captured data using an application program. It is a multifunctional digital dual camera which can do it.

In general, digital cameras capable of directing a variety of photos and videos are the next generation video recording media that can be used for various purposes by digitizing and storing subject data photographed without film. This is a trend. These digital cameras do not require film, and can be edited directly when connected to a computer, and album CDs can be created with various editing effects, and when a printer is connected, photos can be immediately obtained and mass storage can be performed through a storage medium. In addition, the basic structure of a digital camera is a solid-state imaging device (CCD: Charge Coupled Device), which is an image sensor, that receives an image (optical signal) of a subject passed through a lens and an aperture, and the signal converter converts it into a digital signal and stores it in a memory card. The camera's performance depends entirely on the capacity of the solid-state image pickup device and memory card. In addition, in the case of the conventional analog camera, the image of the subject is formed on the film, but in the case of the solid-state digital camera, the object is replaced by the solid-state image pickup device. The image will be created. As a result, the solid state imaging device determines the digital resolution, which determines the accuracy of the camera.

In addition, PC cameras are used for video communication via the Internet, video chatting, video conferencing, and medical examination of companies and hospitals. The PC camera captures an image of a subject of a computer user or the like through a lens like a normal camera lens, and the captured image is converted into an electrical signal and then transmitted to a PC.

However, these digital cameras and PC cameras are a method of compressing and storing only images or outputting them. Therefore, when recording a voice or surrounding sound at the time of photographing is required depending on the situation, a separate voice recorder must be carried, which is very cumbersome. And there is a camcorder that can store and output the image but this has a problem that is not easy to carry. In addition, the conventional digital cameras and PC cameras are complicated in configuration, and accordingly, their size and weight are enormous, thus causing difficulty in assembling and inconvenient to carry. In addition, the configuration of the digital camera and the PC camera is almost the same, but because it is released as a separate device, each has to be purchased as needed, there is a problem that the cost burden increases.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and the first object of the present invention is to integrate the functions of the digital camera and the PC camera to implement two camera functions in one device. It is to provide a multifunctional digital dual camera.

It is a second object of the present invention to provide a multifunctional digital dual camera capable of storing and outputting not only video data but also audio data by adding a voice recording function.

The third object of the present invention is to implement a manual adjustment of the focal length of the lens to shoot the subject in the optimal state desired by the user, and to protect the lens and the viewfinder by attaching a cover to damage from dust or other foreign matter It is to provide a multifunctional digital dual camera to prevent.

The USB I / F unit 760 is interconnected with the CPU 735 and serves to support data exchange between the dual camera 700 and the PC according to a communication standard. That is, the USB I / F unit 760 transmits corresponding data according to various control signals applied from a PC, and the USB I / F unit 760 does not need a driver for installation like other interfaces. In addition, it automatically recognizes a variety of input and output devices and peripherals, so there is no need to make special settings. The dual camera 700 and the PC are connected by a USB cable, and the USB cable is composed of four wires, two of which are used to supply power and the other two are used to transmit data. Here, in the case of exchanging data, it is preferable that the transmitting side (for example, the dual camera 700) and the receiving side (for example, the PC) exchange data while checking the state of the other party. The USB I / F unit 760 used in the present invention has a maximum transmission speed of 12 MHz, and includes USB protocol handling, handling of USB device states, bit streaming, and bit stuffing.

The power management circuit unit 765 serves to supply power required for the operation of the CMOS sensor unit 725 and the CPU 735 by using a battery or a USB power source. The power supplied to the CPU 735 is supplied by converting 4.5V (or 5V) applied from the three batteries into 3.3V through the regulator, and supplying 5V of power to the CMOS sensor unit 725. When the dual camera is connected to a PC, the CPU 735 recognizes and supplies USB power, and at this time, the power applied from the battery is automatically switched off to cut off. In addition, the power management circuit unit 765 includes a protection circuit to prevent the reverse flow of the applied USB power. At this time, when a predetermined time (for example, 30 seconds) elapses, the power is automatically cut off to enter the sleep mode.

Hereinafter, a process of capturing video and audio data using the multifunction digital dual camera according to the present invention will be described in more detail with reference to the accompanying drawings.
