Abstract

A display assistant system includes an image capturing and processing unit for re-encoding main display images, secondary display images or screen capture from running process or a portable computer to images data and capturing the re-encoded images data, an image transmission unit for transferring the re-encoded images data and screen capture from running process, an image display unit for decompressing and displaying the images data and screen capture from running process transferred by the image transmission unit, and an LCD display unit. The image capturing and processing unit has display application programs for adjusting and re-encoding pictures and color domains of main display images to images data. The display assistant system dynamically displays images and screen capture from running process or a portable computer on another LCD display.

Claims

1. A display assistant system, adapted for dynamically displaying images and screen capture from running process of a computer on another LCD display, comprising:

an image capturing and processing unit for re-encoding main display images, secondary display images and screen capture from running process of the desktop or portable computer to images data and capturing the re-encoded images data, comprising display application programs for adjusting and re-encoding pictures and color domains of main display images to images data, the application programs including a main display image interface, simulated secondary display driver programs for capturing secondary display images, and capturing, compressing and transmitting images tool programs for capturing the images data, the secondary display images and screen capture from running process and compressing with different compression ratio,

an image transmission unit for transferring the re-encoded images data and the screen capture from running process;

an image display unit for decompressing and displaying the images data and screen capture from running process transferred by the image transmission unit, the image display unit including an image decoding and display module and an image receiving module which are compliable with the capturing, compressing and transmitting image tool programs; and

an LCD display unit for connecting with the image decoding and display unit, and including at least an LCD display for displaying the processed images data.

2. The display assistant system as recited in claim 1, wherein the capturing, compressing and transmitting images tool programs are executed under Windows environment, and have functions of scaling and re-setting pictures and color domains.

3. The display assistant system as recited in claim 1, wherein the image transmission unit transfers by cable transmission of USB, IEEE 1394 or Ethernet.

4. The display assistant system as recited in claim 1, wherein the image transmission unit transfers by wireless transmission of BlueTooth, WiFi, UWB or WiMAX.

5. The display assistant system as recited in claim 1, wherein the simulated secondary display driver programs are driver programs of simulated images produced by Canada Innobec Corporation.

6. The display assistant system as recited in claim 5, wherein the capturing, compressing and transferring images tool programs process images under Windows XP and Windows Vista with different compression ratio.

7. The display assistant system as recited in claim 1, wherein the capturing, compressing and transferring images tool programs are a compression device with a USB transmission platform, and the image receiving module is a decompression device with a USB transmission platform.

8. The display assistant system as recited in claim 7, wherein transmission wires complying with USB specification are respectively provided at both ends of the image transmission unit for transferring the compressed images data.

9. A display assistant system, adapted for dynamically displaying main display images, secondary display images and screen capture from running process on an electronic product of LCD display, comprising:

an image capturing and processing unit for re-encoding main display images, secondary display images and screen capture from running process of the desktop or portable computer to images data and capturing the re-encoded images data, comprising display application programs for adjusting and re-encoding pictures and color domains of main display images to images data, the application programs including an main display image interface, simulated secondary display driver programs for capturing secondary display images, and capturing, compressing and transmitting images tool programs for capturing the images data, the secondary display images and screen capture from running process and compressing with different compression ratio;

an image transmission unit for transferring the re-encoded images data and screen capture from running process;

an electronic product with an LCD display, an image display unit being built in the LCD display for decompressing and displaying the images data, the secondary display images and screen capture from running process transferred by the image transmission unit, the image display unit including an image receiving module and an image decoding and display module.

10. The display assistant system as recited in claim 9, wherein the capturing, compressing and transmitting images tool programs are executed in a desktop or portable computer, and have functions of scaling and re-setting pictures and color domains.

11. The display assistant system as recited in claim 10, wherein the simulated secondary display driver programs are driver programs of simulated images produced by Canada Innobec Corporation.

12. The display assistant system as recited in claim 11, wherein wherein the capturing, compressing and transferring images tool programs process images under Windows XP and Windows Vista with different compression ratio.

13. The display assistant system as recited in claim 12, wherein the electronic product is an electronic digital frame.

14. The display assistant system as recited in claim 13, wherein the capturing, compressing and transferring images tool programs are a compression device with a USB transmission platform, and the image receiving module is a decompression device with a USB transmission platform.

15. The display assistant system as recited in claim 14, where in transmission wires complying with USB specification are respectively provided at both ends of the image transmission unit for transferring the compressed images data.
