Device and method for transmitting image data
Disclosed is a device and method for transmitting image data that converts 2D image data taken by a digital camera to 3D image data and transmits the 2D and 3D image data to a computer. The image data transmission method that converts 2D image data taken by a digital camera to 3D image data and transmits the 2D and 3D image data to a computer, thereby reducing the required memory capacity and hence the image transfer rate includes: extracting contours from the 2D image data taken by the digital camera; and transmitting the contour extraction data to the computer when the extraction of the contours is completed.
1. An image data transmission device, comprising:
a computer for generating a 2D image signal transmit command or a 3D image signal transmit command by manipulation of keys, receiving 2D or 3D image signals and displaying them;
a digital camera for taking 2D image signals of an object and converting them to digital image signals;
a first-in first-out (FIFO) for storing the 2D digital image signals received from the digital camera in a first-in first-out manner;
a digital signal processor for controlling extraction of contours necessary for 3D image signals from the 2D digital image signals output from the FIFO and storage and reading-out of the extracted contours, converting the 2D digital image signals to 3D image signals using the stored contour extraction data, and outputting the 3D image signals as serial data;
a memory for storing the position and signal magnitude data of the contours extracted from the digital signal processor;
a control and communication logic circuit for receiving the 2D image signal transmit command or the 3D image signal transmit command and a ready command from the computer to output a start command or a stop command to the digital camera, and generating the converted 3D image signals from the digital signal processor; and
an input/output buffer for buffering input/output data between the computer and the control and communication logic circuit.
2. The image data transmission device as claimed in claim 1 , wherein the digital camera starts or ends a shooting operation according to the start command or the stop command output from the control and communication logic circuit, respectively.
3. The image data transmission device as claimed in claim 1 , wherein the digital camera generates a record control signal and sequentially stores the 2D image signals in the FIFO.
4. The image data transmission device as claimed in claim 2 , wherein the digital camera generates a record control signal and sequentially stores the 2D image signals in the FIFO.
