Hereinafter, referring to figs. 1 through Fig. 2, video is utilized to store one embodiment of the present invention in detail
The image processing apparatus of the monitoring of device illustrates.Sending side device comprises display part (110) and sending side
Image processing apparatus (120), reception side apparatus can comprise reception side image processing apparatus (130) and show
Showing portion (140), sending side image processing apparatus (120) can with reception side image processing apparatus (130)
By network (Net Work, NW) transceiving data.Hereinafter, sending side device and reception side apparatus are distinguished
And be described in detail.
1. sending side device (110,120)
With reference to Fig. 1, display device (140) can comprise the multiple displays possessing display picture such as watch-dog
Device (111 to 11N).Such as, available multiple display devices (111 to 11N) are suitably distributed
One image and shown by the controller such as wall controller, or multiple display device (111 to 11N)
Each show different images.
As it is shown in figure 1, receive side image processing apparatus (130) can comprise graphics engine (Graphic Engine,
GE) (121), display driver (Display Device, DD) (122), VRAM (Video
Memory, VM) (123), mirrored drive (Mirror Diver, MD) (124), change
Data extracting section (125), encoding section (126), sending part (127) and video port (129).
Herein, graphics engine (GE) (121) is monitored whether inputting picture change order, as
Really monitored results is input picture change order, then the change order of described picture can be transferred to display and drive
Device (DD) (122).Herein, picture change order is by user pattern (user mode)
The application program of lower implementation and the order that inputs, such as, can be to being currently displayed at display device (110)
The change order in all or part of region of the image of display picture.
If from graphics engine (GE) (121) input picture change order, then display driver (DD)
(122) can be according to the picture change order inputted by the picture number in region of the change in display picture
According to the corresponding region being stored into VRAM (VM) (123).Hereafter, can be to graphics engine (GE)
(121) display request command is passed on, in order to the view data in the region of change can be shown and be shown to display
Picture.Then, graphics engine (GE) (121) passes through video port (128) according to display request command
Pass on the view data in the region of change to display device (110), the view data passed on can be by aobvious
The display picture of showing device (110) and show.
On the other hand, VRAM (VM) (123) is to store the image being displayed on showing picture
The storage medium of data, can be after being divided into multiple region by a display picture, by image data storage
To the address corresponding to regional.The regional split can be described as frame (frame), thus video
Memorizer (VM) (123) is alternatively referred to as frame buffer (frame buffer).
On the other hand, mirrored drive (MD) (124) is for being stored in VRAM (VM)
(123) whether view data changes is monitored, if the image in the region of the change in display picture
Data are stored into VRAM (VM) (123), then can be after sensing this situation, to change
Part or all of change of Data extracting section (125) notice VRAM (VM) (123).
Then, change Data extracting section (125) can extract display from VRAM (VM) (123)
The view data in the region of the change in picture, is communicated to encoding section (126) by the view data extracted.
Encoding section (126) can be the most right together with the view data extracted from change Data extracting section (125)
The attribute information of the view data extracted encodes.Encoded data can be communicated to sending part
(127).Herein, encoding section (126) can be with JPEG (Joint Photograph coding
Experts Group, JPEG) form view data to being extracted and the attribute of view data that extracted
Information encodes.It addition, display picture in more than 2 region simultaneously occur change situation
Under, encoding section (126) can perform coding to the region of change respectively.
Herein, (physics) coordinate in region of change during attribute information can comprise display picture, coding
Packet size, resolution, timestamp, transmission frame number per second (Frame Per Second, FPS),
Display picture be multiple in the case of display picture intrinsic identifier (Unique ID, UID) in
At least more than one.According to an embodiment of the present invention, attribute information includes timestamp, connects
Receive side image processing apparatus (130) by utilizing this timestamp, can show simultaneously carry out respectively encoding and
The region of the plural change of transmission.
Generally, in the case of coding decoder the most H.264, concentrate multiple display picture (if will
One display picture entirety is defined as a frame, then for multiple frames) and disposably encode, therefore
Calculation process needed for coding correspondingly increase and load become many, one display picture in minimum one
In the case of the change of subregion, also whole display picture can be encoded, therefore image processing speed phase
Should increase further on ground.
Therefore, according to an embodiment of the present invention, with JPEG (Joint Photograph
Coding Experts Group, JPEG) form view data to being extracted and the view data extracted
Attribute information encode and transmit, thus there is the advantage that can improve image processing speed on the whole.
Fig. 2 is carrying of the data in the region that the change carried out by one embodiment of the present invention is described
Take and the figure of coordinate in attribute information.
As shown in Figures 1 and 2, if the part in display picture (with reference to the part (a) of Fig. 2)
Region (211,212) change (with reference to the part (b) of Fig. 2), then display driver (DD) (122)
VRAM (VM) can be stored into respectively after extracting the view data in region (211,212) of change
(123) corresponding region.
In fig. 2, represent that plural region (211,212) is same on a display picture
The situation of time point change, in the case, can figure to each region changed (211,212) respectively
Encode as data and transmit.In the part (c) of Fig. 2, (X, the Y) of region (211),
In (X+n, Y), (X, Y+n), (X+n, Y+n) declared attribute information illustratively
Actual coordinate on the display picture in the region of change.
Finally, sending part (127) can pass through network (NW) to receiving side image processing apparatus (130)
Acceptance division (131) transmission encoded data.
As it has been described above, image processing apparatus (120) is at the core schema (kernel being not user pattern
Mode) action is carried out under, so moving under user pattern with the most illustrated
The Graphics Device Interface such as WIN32 (GDI) made is compared, and has the technology improving image processing speed
Effect.
