Abstract

An image transmitter follows a command signal issued by a computer at a remote end and then controls an image sensor through original wiring. The image transmitter includes an image converting unit, an image compressing unit, a packet processing unit and a communication modulating/demodulating unit. The image converting unit converts the image signal picked up by the image sensor to digital image data. The image compressing unit receives the digital image data and then compressing the digital image data by utilizing image compressing technology. The packet processing unit packs the compressed digital image data to a packet of the image data. The communication modulating/demodulating unit transmits the packet of the image data through the original wiring to the computer at the remote end by frequency modulation. The image transmitter further includes a control unit for controlling the image sensor.

Claims

1. An image transmitter for transmitting image signals picked up by an image sensor through original wiring to a computer at a terminal end, comprising:

an image converting unit for converting the image signal picked up by said image sensor to digital image data;

an image compressing unit for receiving said digital image data and then compressing said digital image data by utilizing image compressing technology;

a packet processing unit for packing said compressed digital image data to a packet of said image data; and

a communication modulating/demodulating unit for transmitting the packet of said image data through said original wiring to said computer at said terminal end by radio frequency modulation.

2. The image transmitter according to claim 1, wherein the frequency of said image data is 20 MHz after said image data are modulated by said communication modulating/demodulating unit, and said transmitting speed is extreme 14 Mbps.

3. The image transmitter according to claim 1, wherein said communication modulating/demodulating unit provides said capacity of image data with 16 bits.

4. The image transmitter according to claim 1, wherein said communication modulating/demodulating unit provides said capacity of image data with 16 sets of IP addresses.

5. An image transmitter for following a command signal issued by a computer at a remote end and then controlling an image sensor through original wiring, comprising:

an image converting unit for converting image signal picked up by said image sensor to digital image data;

an image compressing unit for receiving said digital image data and then compressing said digital image data by utilizing image compressing technology;

a packet processing unit for packing and unpacking said image data and said command signal during transmitting and packing said compressed digital image data to a packet of said image data;

a communication modulating/demodulating unit for transmitting said packet of said image data through said original wiring to said computer at a remote end by frequency modulation; and

a control unit for following said command issued by said computer and then controlling the image sensor.

6. The image transmitter according to claim 5, wherein said control unit controls said depth of field of said image sensor.

7. The image transmitter according to claim 5, wherein said control unit controls said monitoring angle of said image sensor.

8. The image transmitter according to claim 5, wherein said control unit controls said focal distance of said image sensor.
