Abstract
Image method for refreshing and coherent video processing unit.Image method for refreshing comprises: (a) judges a position at a renewal part place in a frame; And (b) is according to this position at this renewal part place, determine that the refreshing starting bit of this frame on a panel of this image processor is put.
Description
Technical field
The present invention has about image method for refreshing and coherent video processing unit, and the position being particularly to upgrade part according to frame is decided starting bit that frame is refreshed on panel and put or the image method for refreshing of order and coherent video processing unit.
Background technology
In traditional image processor, the process that a panel shows a frame (frame) comprises this frame write (WRITE) storage device, reads (READ) this frame and frame is shown in panel from this storage device.Wherein, action frame being write a storage device is also referred to as " upgrading the frame in storage device ", and action frame being shown in this panel is also referred to as " refreshing the frame on (REFRESH) panel ".The action of reading frame (READ) and refresh frame (REFRESH) is almost synchronously carried out; But asynchronous due to the operating unit that the frame write operating unit of (WRITE) storage device and self-storing mechanism read (READ) frame; the writing speed of frame is written into (WRITE) storage device reads (READ) frame reading speed with self-storing mechanism is not identical, also must not work in coordination.Panel shows multiple frame continuously, and that is, image processor is continuously engaged in the write (WRITE) of different frame and is read (READ).If the corresponding relation that write (WRITE) frame reads (READ) frame to storage device and self-storing mechanism is not adjusted, when making self-storing mechanism read (READ) frame, there is another frame to write (WRITE) storage device simultaneously, the new frame on panel and old frame then may be allowed to overlap, and on panel, demonstrate incomplete image, and cause rending effect (tearingeffect).
Fig. 1 (a) depicts the schematic diagram that traditional image processor produces rending effect.Wherein, write 0 representative write frame 0 to storage device, reads 0 and represents self-storing mechanism reading frame 0.Same, write 1 representative write frame 1 to storage device, reading 1 represents self-storing mechanism and reads frame 1, by that analogy.As shown in Fig. 1 (a), read 1 and there is no staggered with write 2, read 2 and there is no staggered with write 3, therefore do not interfere with each other.But reading 0 has staggered situation with write 1.That is, the action of self-storing mechanism reading frame 0 and write frame 1 to storage device was carried out in a certain moment simultaneously.And such situation, just likely on panel, cause rending effect.In addition, the ratio value in Fig. 1 (a) is the also corresponding diverse location of frame, and there is directivity.For example, if definition reading 0% correspond to read the frame upper left corner, and read the lower right corner of 100% corresponding frame, then represent frame be from the data in the upper left corner be read then end at the lower right corner data (in other words, frame is when refreshing, refresh to the lower right corner from the panel upper left corner), as shown in Fig. 1 (b).And for example, if definition reading 0% correspond to read the frame upper right corner, and define reading 100% and correspond to the lower left corner of reading corresponding frame, then represent frame be from the data in the upper right corner be read then end at the lower left corner data (in other words, frame is when refreshing, refresh to the lower left corner from the panel upper right corner), as shown in Fig. 1 (c).Accordingly, reading 0 and the staggered action namely representing self-storing mechanism reading frame 0 and write frame 1 to storage device of write 1 are the same positions simultaneously operating on storage device in a certain moment, and cause rending effect.
The renewal of frame has the situation of what is called " part upgrades ", that is in two frames be connected, most picture is identical, only has few part to be different.Now, must not write the data of whole frame, and only need the data writing part frame to get final product (that is only write this write frame one upgrades part).For Fig. 2, the dotted line part of write 0-3 represents a non-updated section, and solid line represents a renewal part.Therefore, overlap at dotted line with write 0-3 if read 0-2, then do not have the problem of rending effect, as read 2 and write 3.But, if overlap in solid line part, still have the problem of rending effect, as read 0 and write 1.It is noted that, rending effect not only can occur in the too slow situation of the reading of former frame (reading 0 in such as Fig. 1 and Fig. 2 is read too slow, and therefore intersection is to the write 1 of next frame), also can occur in the situation that the write of same frame is too slow.For example, the write 4 in Fig. 3 is too slow, and therefore intersection there occurs rending effect to reading 4.
Therefore, need a kind of better mechanism to avoid the problem of rending effect.
Summary of the invention
An object of the present invention is for providing a kind of image method for refreshing and the image processor of avoiding rending effect.
One embodiment of the invention disclose a kind of image method for refreshing, are used on an image processor, comprise: (a) judges a position at a renewal part place in a frame; And (b) is according to this position at this renewal part place, determine that the refreshing starting bit of this frame on a panel of this image processor is put.

Embodiment
Some vocabulary is employed to censure specific element in the middle of specification and follow-up claims.Person with usual knowledge in their respective areas should understand, and hardware manufacturer may call same element with different nouns.This specification and follow-up claims are not used as the mode of distinguish one element from another with the difference of title, but are used as the criterion of differentiation with element difference functionally." comprising " mentioned in the middle of specification and follow-up claim is in the whole text an open term, therefore should be construed to " comprise but be not limited to ".In addition, " couple " word comprise directly any at this and be indirectly electrically connected means.Therefore, if describe a first device in literary composition to be coupled to one second device, then represent this first device and directly can be electrically connected in this second device, or be indirectly electrically connected to this second device by other devices or connection means.
Fig. 4 depicts the calcspar of the image processor 300 using image method for refreshing according to an embodiment of the invention.It is noted that, image method for refreshing is not limited only to the image processor 300 shown in the 4th figure according to an embodiment of the invention, also can be used in the image processor 300 with other structures.As shown in Figure 4, image processor 300 has processor 301, storage device 303, refresh unit 305 and panel 307.Processor 301 is in order to control the write activity (write 0 as described in Figure 1, write 1...) of write frame to storage device 303, and refresh unit 305 read frame in order to self-storing mechanism 303 after (reading 0 as described in Figure 1, read 1...), refresh to panel 307, make panel 307 show up-to-date frame.Refresh unit 305 more can transmit a rending effect control signal TES to processor 301 to avoid the generation of rending effect (effect of TES is specified in rear).Storage device 303 and refresh unit 305 also can be considered a refresh module 306, and it receives this write frame and refreshes this refresh frame on panel 307.
Fig. 5 to Fig. 8 depicts the schematic diagram of image method for refreshing according to an embodiment of the invention.The difference that the schematic diagram of Fig. 5 and Fig. 1 is main is, the reading line (being refresh line) of Fig. 1 read 0,1,2 and write line write 0,1,2,3 all from same starting point (0%).That is in prior art, the write of frame and the reading/refreshing of frame are all from the same position of frame (according to the definition of Fig. 1, from the upper left corner).But in the 5 embodiment of figure 5, the starting bit of write line and reading line puts difference.For example, the write of write line 1,1 ', 2,2 ' is all from 0% s, and reads line 0 and 1 and be all from 100%, that is the write of frame rise/reading/refreshing of terminal and frame/terminal is contrary, and the reading of frame/refreshing order also changes to some extent.Namely spirit of the present invention be by suitable judgment mechanism, that flexibly allocates that this refresh frame reads/refresh rises/terminal or order, so that the probability that the write activity making synchronization occur and read action betide same position reduces, and then avoids rending effect.Such mechanism effectively can prevent rending effect, particularly can improve the rending effect caused because writing speed is too slow.
Under will read 0 and describe this mechanism in detail and how to avoid rending effect write line write 1, write 1 ' and to read line, please notice write 1 and write 1 ' represents the same write activity occurred in the same time mutually, the speed being write 1 ' will be come slower than write 1; Same, the write 2 in Fig. 5 and write 2 ' represent the same write activity occurred in the same time mutually, but the speed of write 2 ' will be come slower than write 2.In Fig. 6 to Fig. 8, thick line part represents in same amount of time, and write activity and read action are respectively in the data of this part of process.It is noted that, be the situation that indicating section upgrades at Fig. 6 to Fig. 8, namely in each figure, the data of write only comprise thick line portion.As shown in Figure 6, open the beginning for the previous period in write and reading/refresh activity, because write and reading/refresh activity are from contrary position, write 1 and write 1 ' are from the position of corresponding 0%, read/refresh from the position of corresponding 100%, therefore do not have the problem of rending effect.And as shown in Figure 7, the difference of itself and aforementioned 5th figure is, read the frame data of position periphery of corresponding 50% in reading 0 after, the data of write same position are just gone in write factory and write 1, therefore also do not have the problem of rending effect.Same, as shown in Figure 8, when writing and reading/refresh activity closes to an end, read the frame data that 0 is the position of reading corresponding 0%, and to write 1 ' with write 1 be the frame data of position of write corresponding 100%, therefore also do not have the problem of rending effect.
According to the description of Fig. 6 to Fig. 8, change if can understand the starting bit reading/refresh and put or order, make it stagger with the position of write, under the situation that part upgrades, just can reduce the probability that rending effect produces.Even if writing speed is comparatively slow, also rending effect can not be produced as write 1 '.Therefore, if the starting bit that can change readings/refreshing according to the position upgrading part is put or order, just can the probability of more effective reduction rending effect generation.
Fig. 9 (a), 9 (b), 10 (a) and 10 (b) depict the renewal part of corresponding diverse location and adopt the different starting bit that refreshes to put or the schematic diagram of order.Generally speaking, under part more news, this renewal part may comprise one and mainly upgrade part and multiple secondary renewal part.The main part that upgrades may occupy larger area based on main renewal part with the differentiation of secondary renewal part, but not as limit.Below illustrate that the position only mainly upgrading part according to this changes the starting bit reading/refresh and puts or order.As shown in Fig. 9 (a), the main part that upgrades is positioned at Lower Half, therefore can read from the upper left corner/refresh, then end at the lower right corner.Or, can read from the upper right corner/refresh, then end at the lower left corner.And for example shown in Fig. 9 (b), the main part that upgrades is positioned at the first half, therefore can read from the lower right corner/refresh, then end at the upper left corner.Or, can read from the lower left corner/refresh, then end at the upper right corner.And as shown in Figure 10 (a), the main part that upgrades is positioned at right-hand part, therefore can reads from the upper left corner/refresh, then end at the lower right corner.Or, can read from the lower left corner/refresh, then end at the upper right corner.And for example shown in Figure 10 (b), the main part that upgrades is positioned at left side, therefore can read from the lower right corner/refresh, then end at the upper left corner.Or, can read from the upper right corner/refresh, then end at the lower left corner.
From Fig. 9 (a), 9 (b), 10 (a) and 10 (b), upgrade part to stagger and avoid producing rending effect, reading/refreshing two parameters can be adjusted: starting bit is put and order.If starting bit is put from main, to upgrade part enough far away, then the order no matter reading/refresh why, all can avoid generation rending effect.But be limited to the main impact upgrading part area sometimes, possible starting bit is put and is had no idea from main that to upgrade part too far away, just can be read by adjustment/order of refreshing avoid generation rending effect.Or, also can merge two parameters and be used for reaching better effect.Reading/the starting bit of refreshing is selected to put and can freely arrange in pairs or groups with order, as long as there is rending effect when frame can not be allowed to show according to the position mainly upgrading part.
In detail, the judgement that the starting bit reading refreshing is put only may get four corners that a frame comprises, i.e. the upper left corner, the upper right corner, the lower left corner and the lower right corner, refreshes starting bit as alternative candidate and put.Respectively these four corners of comparison and this mainly upgrade the distance of part, and to put using one of distance at least one corner farthest as refreshing starting bit.As shown in Fig. 9 (a), the main part that upgrades is positioned at Lower Half, and distance corner is farthest the upper left corner and the upper right corner.Accordingly, one of them is put as starting bit to select the upper left corner and the upper right corner.On the other hand, the judgement of the order reading/refresh can also based on above-mentioned judged result.In detail, namely select so that one of them is put as starting bit apart from corner farthest, to start to read/refresh towards the direction in another distance corner farthest, and end at the order in a corner of close together.Same as shown in Fig. 9 (a), the main part that upgrades is positioned at Lower Half, and distance corner is farthest the upper left corner and the upper right corner.Can be then refresh starting bit to put to read the direction towards the upper right corner/to refresh from the upper left corner, then end at the lower right corner.Or, can the upper right corner be refresh starting bit to put to start towards the direction in the upper left corner to read/refresh, then end at the lower left corner.Should be specifically noted that, when distance corner farthest only has one, then can select to put as starting bit apart from corner farthest, to start to read/refresh towards the direction in the secondary corner far away of distance, and end at the order in a corner of close together.
The rending effect control signal TES that aforesaid embodiment can more be arranged in pairs or groups in Fig. 4 is to produce better effect.Referring again to Fig. 4 and Fig. 5, rending effect control signal TES has high level part and low level part.Wherein low level part refers to that the refresh unit 305 in Fig. 4 implements reading/refresh activity, and high level part refers to that refresh unit 305 presents idle state and do not implement reading/refresh activity.Therefore, by rending effect control signal TES, clearly can know the time of reading/refresh activity, the sart point in time of write activity therefore can be made to stagger in the sart point in time of reading/refresh activity, as shown in Figure 5.More to reduce the probability that rending effect produces.
Figure 11 depicts the flow chart of image method for refreshing according to an embodiment of the invention.Content of the present invention is more understood please also refer to Fig. 4 and Figure 11.So notably, the step shown in Figure 11 coordinates the device of Fig. 4 as illustrative purposes, should as the foundation limited the scope of the invention.
Figure 11 contains the following step:
Step 1001
Processor 301 determines that one in a write frame upgrades part.
Step 1003
Processor 301 judges a position at this renewal part place in this write frame.
Step 1005
Processor 301 selects suitable refreshing starting bit to put or order according to this position of this renewal part, and is set to refresh unit 305.
Step 1007
Processor 301 starts to write this renewal part to storage device 303.
Other detailed steps can push away easily according to previous embodiment, therefore repeat no more in this.
According to aforesaid embodiment, the part that reading/refresh activity staggered frame can be allowed to upgrade, therefore can effectively reduce the probability that rending effect occurs.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the claims in the present invention change and modify, and all should belong to covering scope of the present invention.
