Embodiment
Please arrange in pairs or groups with reference to Fig. 2 A and Fig. 2 B, Fig. 2 A is the schematic diagram of the image-processing circuit 200 of a preferred embodiment of the present invention, and Fig. 2 B is the operating process schematic diagram of the image-processing circuit 200 shown in Fig. 2 A.Image-processing circuit 200 includes a storage device 205, one compressor circuit 210, two buffer 215a and 215b, a plurality of First Line buffer 220a～220g, a plurality of second line buffer 225c～225e, one decompression circuit 230, one treatment circuit 235 and a mobile estimating and compensating circuit 240, wherein storage device 205 is generally a DRAM (Dynamic Random Access Memory), and line buffer 220a～220g and 225c～225e realize with static random access memory conventionally, and image-processing circuit 200 can be designed to a single-chip, or storage device 205 is adopted to independent another Dram chip of one-tenth, separate with image-processing circuit 200 chips.Storage device 205 is source image data DATAsource (step 405) that come in by image-processing circuit 200 outsides for storing, and compressor circuit 210 is used for receiving the stored source image data DATAsource of storage device 205 and DATAsource is processed, produce the image data DATAcompressed (step 410) after a compression, and be stored in compression section buffer 215a, and generation one remaining image data DATAresidual, and be stored in nubbin buffer 215b, wherein after compression, image data DATAcompressed includes plural line pixel data (line pixels).Follow that a plurality of First Line buffer 220a～220g can receive in order and temporary compression after image data DATAcompressed in these a plurality of line pixel datas, and a plurality of second line buffer 225c～225e can receive and temporary remaining image data DATAresidual (step 415).In decompression circuit 230, include a plurality of decompression unit 2300a～2300g, correspond to respectively a plurality of First Line buffer 220a～220g, this image data DATAcompressed that is used for decompressing, to produce respectively the image data DATAdecompressed (step 420) after a decompression.Finally the image data DATAdecompressed after this decompression is sent to mobile estimating and compensating circuit 240, carries out mobile estimating and picture interpolation for mobile estimating and compensating circuit 240.
In the present embodiment, compressor circuit 210 is to adopt each line pixel data width (data width) in the image data DATAsource of brachymemma (truncate) source to produce corresponding line pixel data in the rear image data DATAcompressed of compression while carrying out data compression, and each line pixel data can be rgb format, YUV color form or other format color data, taking rgb color as example, if the data width of a R pixel data is 10 positions, in the present embodiment, compressor circuit 210 can be punctured into the data width of this R pixel data 5 positions, that is, remove 5 low levels (lower bit) and leave other 5 high positions (higher bit), owing to by 5 low levels of brachymemma being the position that importance is low, impact on image quality is less.When compressing rear image data DATAcompressed reduction, additional (append) the specific bit value (bit pattern) of decompression circuit 230 is to compressing corresponding line pixel data in rear image data DATAcompressed, make each line pixel data return back to the data width before compression, to produce the rear image data DATAdecompressed that decompresses; For example, concerning each line pixel data, all additional 5 position ' 0 ' to the low portions of this line pixel data of decompression circuit 230 make the data width of this line pixel data become 10 positions again, deal with in order to subsequent movement estimation and compensating circuit 240.
From the above, because the present embodiment compressor circuit 210 is that the method for adopting brachymemma data width is carried out data compression process, and adopt the additional method of specific bit value (bit pattern) and carry out decompression.Therefore, the image data DATAdecompressed after the decompression that decompression circuit 230 produces is not equal to original source image data DATAsource, and in the time that image display is on screen, human eye may perceive distortion to a certain degree.So, human eye is still difficult for perceiving image frame distortion when making to produce loss of accuracy in image data, image data DATAcompressed after compression, compressor circuit 210 separately can produce remaining image data DATAresidual, wherein DATAresidual includes plural remaining line pixel data, this remaining image data DATAres idual can first be buffered in remaining buffer 215b, and coordinate First Line buffer sequential to be temporary in a plurality of second line buffer 225c～225e, the first buffer 220c and the second buffer 225c system correspond to same level scanning linear, the first buffer 220d and the second buffer 225d system correspond to same level scanning linear, the rest may be inferred, treatment circuit 235 is the data (step 425) of adjusting the part in the image data DATAdecompressed after decompression according to the remaining image data DATAresidual cushioning in second line buffer 225c～225e, therefore, mobile estimating and compensating circuit 240 are according to carrying out mobile estimating and compensation (step 430) through the image data DATAdecompressed of partial-compensation.In implementation, in the time that the data width of each line pixel data of source image data DATAsource is punctured into 5 positions with the rear image data DATAcompressed of generation compression by compressor circuit 210, it is to get 5 low levels of each line pixel data as remaining image data DATAresidual, so the data that in the image data DATAdecompressed after decompression, a part of processed circuit 235 is adjusted can be reduced into the data before compression completely and can not caused data accuracy loss.
Because the distortion of static images object can more easily be examined and know by human eye than the distortion of movable image object, so, image data after the present embodiment designs a treatment circuit 235 adjustment member is decompressed, if mobile estimating and compensating circuit 240 can carry out interpolation according to the image data that does not produce loss of accuracy and go out static images object to make this treat to correspond to a static images object by inter polated pixel.For example, when image-processing circuit 200 be for picture in the 4th article scanning online a certain pixel carry out image interpolation, and the search area (search range) of the 1st article～the 7th article scan line while being mobile estimating, compressor circuit 210 can be in order by the RGB data of the line pixel data of the 1st article～the 7th article of scan line respectively width be punctured into 5 positions, therefore, in the time that data width is 10 positions, First Line buffer 220a～220g can store respectively 5 high positions of each line pixel data in the 7th article～the 1st article scan line, for example, First Line buffer 220a can cushion 5 high positions of each line pixel data in the 7th article of scan line, by that analogy, on the other hand, compressor circuit 210 can export to produce remaining image data DATAresidual by 5 low levels of each line pixel data in the 3rd article～the 5th article scan line in order, so, second line buffer 225c～225e can store respectively 5 low levels of each line pixel data in the 5th article～the 3rd article scan line, for example, the second line buffer 225c can cushion 5 low levels of each line pixel data in the 5th article of scan line, by that analogy.Therefore, running according to above-mentioned mentioned decompression circuit 230 with treatment circuit 235, mobile estimating and compensating circuit 240 can receive corresponding to the image data after the decompression of each pixel of the 1st article～the 7th article of scan line, after the corresponding decompression of line pixel data of wherein the 3rd article～the 5th article of scan line, image data is equal to the raw video data of the line pixel data of the 3rd article～the 5th article of scan line of source image data DATAsource, that is, article 3, the data of the line pixel of～5th article scan line do not produce any loss of accuracy, after the corresponding decompression of line pixel in all the other scan lines, image data has a little difference with the raw video data of all the other scan line center line pixels of source image data DATAsource, in other words, after the decompression of the line pixel of all the other scan lines, image data has loss of accuracy slightly, but the image frame distortion that this loss of accuracy causes will be difficult for being examined and knowing by human eye.
For instance, for example, when a mobile estimating result of mobile estimating and compensating circuit 240 indicates in the time that a vertical displacement of the corresponding imaged object of inter polated pixel continuous two pictures in front and back exceeds a specific image space scope (when vertical displacement exceedes the spatial dimension of the 3rd article～the 5th article of scan line), mobile estimating and compensating circuit 240 can judge that this imaged object is that imaged object a foundation with vertical movement do not produced and treat inter polated pixel by image data after the adjusted decompression of remaining image data DATAresidual institute, that is, for example, according to the 1st article, article 2, article 6, image data produces and treats inter polated pixel or after the online corresponding decompression of line pixel of the scanning such as the 7th article, now in fact this imaged object is the imaged object moving, and mobile estimating and compensating circuit 240 use there is a little loss of accuracy's decompression after image data produce the picture of this imaged object and be difficult for being examined and knowing by human eye.In addition, in the time that vertical displacement is less than the spatial dimension of the 3rd article～the 5th article of scan line, mobile estimating and compensating circuit 240 can judge that this imaged object is that an imaged object without vertical movement is also according to producing and treat inter polated pixel via image data after the adjusted decompression of remaining image data DATAresidual institute, that is, produce and treat inter polated pixel according to image data after the corresponding decompression of line pixel of the 3rd article～the 5th article of scan line, now treat that the imaged object that inter polated pixel is corresponding may be that a static imaged object or only has the imaged object moving horizontally, mobile estimating and compensating circuit 240 produce and treat that the image of interpolation block MB can't cause the problem of any distortion according to image data (not producing loss of accuracy's image data) after the corresponding decompression of line pixel of the 3rd article～the 5th article of scan line.
In addition, the compressor circuit 210 of the present embodiment can optionally be exported remaining image data DATAresidual to the second line buffer 225c～225e according to the mobile estimating result of mobile estimating and compensating circuit 240.Due to the object of remaining image data DATAresidual be for adjusting image data DATAdecompressed after a part of decompression so that proper when carrying out interpolation and go out the picture of a static images object according to image data DATAdecompressed after decompressing human eye be difficult for perceiving image frame distortion, therefore, when mobile estimating result indicates one in the time that inter polated pixel system corresponds to an imaged object with vertical movement, compressor circuit 210 can not exported remaining image data DATAresidual to line buffer 225c～225e; And be while corresponding to an imaged object without vertical movement when mobile estimating result indicates until inter polated pixel, compressor circuit 210 can remaining image data DATAresidual to the second line buffer 225c～225e of output.This design belongs to category of the present invention.
Moreover, in order further to save the storage volume (that is storage volume of static random access memory) of the line buffer using, can select image data after uncomfortable whole decompression, in other words, it ties up to and under sacrificial section image quality, saves as best one can static random access memory used.Please refer to Fig. 3 A, Fig. 3 A is the schematic diagram of the image-processing circuit 300 of another embodiment of the present invention.Different from image-processing circuit 200 is, in image-processing circuit 300, do not comprise the remaining buffer 215b shown in Fig. 2 A, second line buffer 225c～225e and treatment circuit 235, therefore, it is the data width of each line pixel data of brachymemma with compressor circuit 210, decompression circuit 230 is at the rear of decompression and the image data DATAcompressed after compression cannot be reduced to original source image data DATAsource completely, so, image data DATAdecompressed after decompression can have data difference slightly with source image data DATAsource, and this data difference can will cause the image distortion of part on picture, but, this image distortion for saving the static random access memory using as far as possible under the prerequisite in sacrificial section image quality, system can be uncared-for.The operating process of image-processing circuit 300 is shown in Fig. 3 B, in Fig. 3 B, except step 515,525 and Fig. 2 B in step slightly different, step 505,510,520 is the step 405,410,420 that is similar to Fig. 2 B, therefore, be in tediously long for fear of length, separately do not repeat at this.
Combine it, image-processing circuit 200/300 of the present invention is to utilize the mode of data compression to save the storage volume of line buffer; And be difficult for examining in order to ensure human eye the image frame distortion that primary data loss of accuracy causes, for example, for the higher part of quality of image demand (static image), image-processing circuit 200 can be reduced to original source image data by data after corresponding to the quality of image and need the decompression of higher partial image before mobile estimating/compensating circuit 240 is processed, to take into account the cost of saving line buffer and the object that maintains image frame quality to a certain degree.Should be noted, above-mentioned implementation mode is only for convenient explanation running of the present invention, but not restriction of the present invention; For example, the number of above-mentioned First Line buffer can also be designed to other number, be not limited to 7, the scope that need to search while generally designing with mobile estimating is relevant, data width must be punctured into 5 positions and compressor circuit 210 is also non-limiting, and the compress mode of compressor circuit 210 also can use other data compression scheme but not only limit to brachymemma data width, decompression circuit 230 is used corresponding decompression scheme.In addition, there is loss of accuracy's slightly decompression after image data be still applicable to carry out mobile estimating, this is because the object of mobile estimating is to find out motion-vector, but not utilizes the image data with loss of accuracy to carry out image interpolation.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the claims in the present invention change and modify, and all should belong to covering scope of the present invention.
