FIG. 3 is a flow chart showing a process for transmitting 3D image signals of thedigital signal processor 104 according to the embodiment of the present invention;FIG. 4 is a flow chart showing an algorithm for contour extraction according to the embodiment of the present invention; andFIG. 5 is a diagram showing the format of contour extraction data according to the embodiment of the present invention. - Below is a detailed description of the operation for transmitting 3D image signals according to the preferred embodiment of the present invention with reference to
FIGS. 2 to 5 . - As the user manipulates the
computer 112 to generate a scan start command, a scan stop command, a 2D image transmit command or a 3D image transmit command, the command is buffered through the I/O buffer 110 and applied to the control andcommunication logic circuit 108. The control andcommunication logic circuit 108 sends the start command to thedigital camera 100 and the 2D image transmit command or the 3D image transmit command to thedigital signal processor 104 through a serial data input (SDI). Thedigital camera 100 receives the start command to start an object shooting operation and sends 2D image data with a write signal to the FIFO 102, which stores the 2D image data in a first-in first-out manner. The 2D image data output from thedigital camera 100 have a grey resolution of 8 bits and a display resolution of 1024.times.1024 and store image data of 1 Mega byte. Once the 2D image data is stored in the FIFO 102, thedigital signal processor 104 processes image signals according to the 2D image transmit command or the 3D image transmit command for transmission of the image signals, which will be described below with reference toFIG. 2 . - First, the
digital signal processor 104 initializes the system, instep 201, and checks instep 202 whether or not the 2D image transmit command is received from thecomputer 112 through the control andcommunication logic circuit 108. If the 2D image transmit command is received, thedigital signal processor 104 proceeds tostep 203 in which it sends a read signal to the FIFO 102 to read out the stored data, stores the data in thememory 106, synchronizes the stored 2D image data with a serial clock (SCL) and sends them to the control andcommunication logic circuit 108 through a serial data output (SDO) line. Then the control andcommunication logic circuit 108 buffers the 2D image data through the I/O buffer 110 via an I/O bus and sends them to thecomputer 112. The digital signal processor checks instep 204 whether or not an image transmit stop command is received from thecomputer 112 through the control andcommunication logic circuit 108. If the image transmit stop command is received, thedigital signal processor 104 returns tostep 202. If the 2D image transmit command is not received instep 202, thedigital signal processor 104 proceeds tostep 204 in which it checks whether or not a 3D image transmit command is received from thecomputer 112 through the control andcommunication logic circuit 108. If the 3D image transmit command is received, thedigital signal processor 104 proceeds tostep 205 in which it checks whether or not a scan start command is received through the control andcommunication logic circuit 108. If the scan start command is received, thedigital signal processor 104 proceeds tostep 206 in which it sends a read signal to theFIFO 102 to read out the stored 2D image data, extracts a contour necessary for 3D image from the 2D image data and stores the extracted contour in thememory 106. The algorithm for contour extraction is illustrated inFIG. 4 and its operation will be described below with reference toFIG. 4 . - In
step 301, thedigital signal processor 104 sets a row index and a column index at zero in order to acquire a contour height and a signal magnitude from one 2D image data for the first one frame. Instep 302, thedigital signal processor 104 checks whether or not the low index is zero (ROW=0). If the row index is zero, thedigital signal processor 104 substitutes the contour height and the signal magnitude for variables in order to extract the contour height and the signal magnitude of the 2D image data, instep 303. Subsequently, thedigital signal processor 104 increases the column index by one (COL=COL+1), in step 306, and checks instep 307 whether or not the column index is less than 1024. If the column index is less than 1024, thedigital signal processor 104 returns tostep 302. - If the row index is not zero in
step 302, thedigital signal processor 104 sets the contour height and the signal magnitude and stores the set values in thememory 106, instep 304. Here, High[ ] is the position of the contour and Signal[ ] is the signal magnitude. For example, when High[100]=200 and Signal[100]=127, the 100.sup.th position of the contour has a height value of 200 and the signal magnitude (potential energy) is 127. Instep 305, thedigital signal processor 104 checks whether or not the current signal magnitude is greater than the previous one. If the current signal magnitude is greater than the previous one, thedigital signal processor 104 substitutes the value of the current signal magnitude for the variable in step 306. Thedigital signal processor 104 increases the column index by one, instep 307, and checks instep 308 whether or not the column index is 1024. If the column index is not 1024, thedigital signal processor 104 returns tostep 302. Otherwise if the column index is 1024, thedigital signal processor 104 sets the column index at zero and increases the row index by one, instep 309. Subsequently, thedigital signal processor 104 checks in step 310 whether or not the row index is 1024. If the row index is not 1024, thedigital signal processor 104 returns tostep 302. Otherwise if the row index is 1024, thedigital signal processor 104 considers that the image signal for one frame is completely processed, and ends the operation for acquiring the contour height and the signal magnitude. This procedure is repeated to convert more than one 2D image signals to 3D image signals. - Following the contour extraction, the
digital signal processor 104 checks instep 207 whether or not the extraction of the contour from the 2D image signals for one frame is completed. If the contour extraction is completed, thedigital signal processor 104 stores the height information High[ ] and the grey information Signal[ ] for the contour extraction data in a data format as shown inFIG. 5 in thememory 106 and sends the stored 3D image data to thecomputer 112 via the control andcommunication logic circuit 108 and the I/O buffer 110, instep 208. The 3D image data format shown inFIG. 5 has height and grey information and requires, for example, 10 bits for representing the height information and 8 bits for the grey information in the case of 1024.times.1024 display resolution and 8-bit grey resolution. Accordingly, two bytes for height information and one byte for grey information, i.e., totally three bytes are required for representing one point of the contour and a memory of 3 Kbytes is used for one contour. Subsequently, thedigital signal processor 104 checks instep 209 whether or not the transmission of the 3D image data is completed. If the transmission is completed, thedigital signal processor 104 returns to step 202 for transmission of another image data. - The 3D image is composed of several contours. When the scanning direction of the
digital camera 100 is vertical, the contour has horizontal coordinates and height information and the vertical coordinates are determined by the moving distance of thedigital camera 100 the moment thedigital camera 100 shoots the 2D image. Since the scanning speed is determined at the time of hardware manufacture, the 2D image taken by thedigital camera 100 is converted to a 3D image and sent to thecomputer 112. Then thecomputer 112 constructs 3D image data in consideration of the contour information and the moving distance of the camera and displays them. - As described above, following extraction of the contour from the 2D image signals taken by the
digital camera 100 and acquisition of the grey level of each extracted point, the contour and the grey signal for each point on the contour rather than the 2D image data are sent to thecomputer 112. Thecomputer 112 can process the 3D image signals only from the height and grey information of the contour. For example, when the X-directional resolution and the height resolution are both 1024 and the number of contours is 512, the prior art must transmit 512 2D images having a resolution of 1024.times.1024. If the grey information is eight bits in this case, the data amount to be transmitted is 4 Gbits (=1024.times.1024.times.512.times.8). However, the present invention, which uses 2 bytes for the height resolution, requires 64 Mbits (=1024.times.16.times.512.times.8), thus reducing the data amount to 1/60. - As described above, the present invention transmits 2D image data taken by a digital camera, or converts the 2D image data to 3D image data and then transmits the 3D image data to a computer, according to a 2D image transmit command or a 3D image transmit command received from the computer, thereby increasing the transmission speed and reducing the required time for transmitting the 3D image data. Moreover, the present invention uses a DSP technology to reduce the amount of data for conversion of 2D image data to 3D image data and increase the required memory capacity, thereby decreasing the production cost.
- While the invention has been shown and described with reference to a certain preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
