Description

Digital still camera for transmitting video information and its transmission method

The present invention relates to a digital still camera for transmitting image information.

More specifically, the present invention relates to a digital still camera for transmitting image information obtained by adding a communication processing device capable of transmitting image information to a portable communication terminal to a conventional digital still camera, and a transmission method thereof.

In general, a digital still camera (DSC) converts an image incident through a lens into an electrical signal using a photoelectric conversion element such as a charge coupled device (CCD), and then stores the image in a semiconductor memory device. It is a storage device.

That is, all digital still cameras that intermittently capture an image and store the same in a semiconductor memory device may be connected to a computer device to exchange data.

In addition, by storing the image data photographed by the digital still camera in the storage device of the computer device, it is possible to improve the image storage capacity, and to control the operation state of the digital still camera using the computer device.

These digital still cameras have recently been expanded with the spread of home computer devices, and they can directly view and edit images taken by the computer display device using computer devices to create multimedia home pages or presentation materials, or to edit the edited images with the printer. It can be output to the same output device, or it can be stored in a hard disk drive or a compact disk, which is in the spotlight.

For example, you can make a homepage using images taken with a digital camera by connecting to the Internet, create various reports by inserting the shot images, and create an electronic album with commemorative photos such as graduation and marriage. It can be made or stored in a recording medium such as a diskette.

Such digital still cameras typically provide VGA (640 x 480) or higher resolution and have a large memory to record and record a large number of subjects.

A lens 11 that enlarges and transmits a light source of a subject, an imaging device (Charge Coupled Device (CCD)) 12 that converts an optical signal of the subject into an electrical signal, and analog pixel information input to the imaging device 12. An A / D converter 13 for converting a digital signal into a digital signal, a digital signal processor (DSP) 14 for processing a digital signal converted by the A / D converter 13 into image data; A main controller 15 for calculating the output signal of the digital signal processor 14 and controlling the entire system, a memory 16 for storing information of the main controller 15 and the entire system, and compressing still picture data. A Joint Photographic Coding Experts Group (JPEG) 17 and a PC interface unit 18 connected to a computer to output information stored in the memory 16.

In the conventional digital still camera configured and operated as described above, the image information of the digital still camera 21 is directly transmitted to the PC 22 or the notebook 22 when the image information of the photographed picture is to be transmitted immediately. Image information was transmitted to a commercial communication network and a place to be sent to the Internet by using a transmission device (MODEM) 23.

However, when information is transmitted in the order shown in FIG. 2, when a user takes a lot of data and transmits it, it is time-consuming and cumbersome to work through the PC 22 or the notebook 22 with limited diskette capacity.

In particular, in the press release or photographing used for the time-broadcasting broadcasting is required to send information quickly, the conventional transmission method using only a digital still camera has a lot of problems.

Accordingly, an object of the present invention is to add a communication processing device capable of transmitting image information to a portable communication terminal to a digital still camera and transmit the information using the portable communication terminal, thereby speeding up and transmitting a large amount of information. To provide a digital still camera and a method of transmitting the same.
