Description
Technical field
The present invention relates to a kind ofly detect mobile apparatus and method, and be particularly related to and a kind ofly have chromaticity sampling error (chroma up-sampling error CUE) removes the dynamic adaptable deinterlacing device and the method for device.
Background technology
In general, mobile detection utilizes the difference of object pixel in same parity field (The Same Parity Field) to judge whether these object pixels are moving.When difference during greater than a set in advance threshold values of reserving (Threshold), expression have in the film in have amount of variability (Variation) and produce, so the pairing pixel of decidable is mobile pixel; And when difference during less than threshold values, expression does not have the generation of amount of variability, therefore judges that then pairing pixel is static pixel.
By above-mentioned mobile detection method, can obtain mobile message in the mobile object so that reference to be provided, whether see that usage space interpolation method (Spatial Interpolation) or temporal interpolation method (Temporal Interpolation) try to achieve required figure field data.Wherein different is that the temporal interpolation method is to be used for calculating the pixel value that does not have the mobile object zone; And the spatial interpolation rule is to be used for calculating the pixel value that the mobile object zone is arranged.
On the other hand, in order to reduce the image size of video signal, the color component in the video signal can be compressed into the 4:2:0 sample format usually.Particularly, for the insensitive characteristic of color component, the color component in the video signal data is usually by down-sampling based on human eye, the colouring information of a reserve part.Common down-sampling form has comprised 4:2:2 sample format, 4:1:1 sample format and 4:2:0 sample format.
With the pixel that comprises R, G and B color component is example, and in the processing procedure with the 4:2:2 down-sampling, the R of pixel, G and B color component can be converted to brightness Y and color component U and V by equivalence, and the sampling interval of pixel color component is a twice.That is to say to have only a color of pixel component can be sampled and be shared among per two pixels.
Yet, when the video signal that is compressed to the 4:2:0 sample format being carried out three-dimensional deinterleave when handling, if before merging in figure and back figure 's the stagnant zone pairing color of pixel component show, then can produce chromaticity sampling error (chroma up-sampling error, CUE).
Fig. 1 illustrates a kind of chromaticity sampling error of being produced when deinterleave is handled of carrying out.With reference to Fig. 1, when the deinterleave processing is carried out in the progressive figure field that to the image size is 8 * 8, scan line is divided into strange figure field and bigraph field, wherein strange figure field comprises many odd-numbered scan lines of progressive figure field, and the bigraph field comprises many even-line interlace lines of progressive figure field, and these pixels are represented a plurality of colour elements with shade block partly.Then, when at the same time the 4:2:0 down-sampling being carried out in strange figure field and bigraph field, the data of one of them of per two scan lines can be retained the data of getting off to sample and being used as these two scan lines, with the image size of further reduction original graph field.Yet, carry out deinterleave when handling when the strange figure field of having carried out down-sampling and bigraph field to above-mentioned two, can alternately carry out up-sampling with answer figure field to the scan line of strange figure field and the scan line of bigraph field.As the 3rd part that Fig. 1 illustrated, colour element is misplaced so that the edge of the colored region of the figure field after replying presents zigzag.
In order to solve the problem of above-mentioned chromaticity sampling error, conventional art utilizes low pass filter to carry out up-sampling, but this method can make the profile that has obvious heterochromia in the figure field thicken.For the such problem of thorough solution, then need the component of the pixel in the colored region of preceding figure field and figure field, back is replaced, shown in the 4th part among Fig. 1.In more detail, the component of the pixel in strange figure can be replaced with the component of pixel in the next one figure field, and the component of the pixel in the bigraph field can be replaced with the component of pixel in the previous figure field.
Yet, adopt same parity field owing to moving detector is essential, thereby the dynamic adaptable deinterlacing technical finesse needs the data of at least three figure fields with accurate detection stagnant zone and moving area.If desire to remove chromaticity sampling error among three figure of input in order to moving detections, then need at least five data of scheming the field, and this measure meeting expend a large amount of buffering areas.

For instance, Fig. 4 illustrate one embodiment of the invention a kind of removing before the schematic diagram of method of chromaticity sampling error of scan line in figure.With reference to Fig. 4, the scan line B before supposing among the figure F_previous is a stagnant zone.When chromaticity sampling error is removed, the scan line B among the preceding figure field F_previous can with scan line A among the present figure field F_current or scan line C double replacement mutually.
Handle in order to carry out two-dimensional de-interlacing (2DDI), that is spatial interpolation handles, at present the data among the figure F_current should need correctly and the chromaticity sampling error of existence therebetween also this is removed.In the present embodiment, second chromaticity sampling error removes device 206 and receives data among a figure F_current at present and the back figure F_next, and removes first scan line among the present figure field F_current and the chromaticity sampling error of three scan line.Specifically, before carrying out the two-dimensional de-interlacing processing, at present the color component of the mistake among the figure F_current should with color component among a preceding figure field F_previous or back figure F_next double replacement mutually, to obtain the correct color component among the figure F_current ' at present.
In more detail, second chromaticity sampling error removes device 206 and detects the chromaticity sampling error of scheming first scan line among the F_current at present, if detect the chromaticity sampling error of first scan line, at present the color component of first scan line among the figure F_current replace can by second chromaticity sampling error remove device 206 and with a preceding figure field F_previous or a back figure F_next in last scan line of first scan line or the color component of second scan line replace.In addition, second chromaticity sampling error removes the chromaticity sampling error that device 206 also can detect the three scan line among the present figure field F_current, if detect the chromaticity sampling error of three scan line, at present the color component of the three scan line among the figure F_current can by second chromaticity sampling error remove device 206 and with a preceding figure field F_previous or a back figure F_next in second scan line or the color component of next bar scan line of three scan line replace.
For instance, the schematic diagram of the method for Fig. 5 a kind of chromaticity sampling error that removes the scan line in the present figure field of illustrating one embodiment of the invention.With reference to Fig. 5, suppose that the scan line A and the scan line C that scheme among the F_current at present are stagnant zone.When chromaticity sampling error is removed, at present the scan line A among the figure F_current can with scan line D among the preceding figure field F_previous or scan line B double replacement mutually; Perhaps, with back figure F_next in scan line D or scan line B double replacement mutually.In addition, at present the scan line C among the figure F_current can with scan line B among the preceding figure field F_previous or scan line E double replacement mutually; Perhaps, with back figure F_next in scan line B or scan line E double replacement mutually.
In the present embodiment, the data among the present figure F_current ' remove device 206 outputs and further input to deinterleave unit 208 to carry out the deinterleave processing from second chromaticity sampling error.More particularly, deinterleave unit 208 receives first scan line of having handled among the figure F_current ' at present and the data of three scan line, and utilizes first scan line and three scan line to carry out that interpolation is handled and second scan line of trying to achieve the deinterleave among the present figure field F_current '.
The data of the mobile message that selector 210 reception moving detectors 202 are exported, correct preceding figure field F_previous ' and the data of having carried out two-dimensional de-interlacing processing F_2DDI present figure field afterwards, and the data of second scan line in the field are schemed in the dateout conduct of selecting first chromaticity sampling error to remove device 204 or deinterleave unit 208 adaptively according to the mobile testing result of moving detector 202 at present.In more detail, if first scan line among the present figure F_current of moving detector 202 detections and the pixel between the three scan line are static pixel, then selector 210 can selection first chromaticity sampling error remove the data of the dateout of device 204 as second scan line.On the other hand, be mobile pixel as if first scan line among the present figure F_current of moving detector 202 detections and the pixel between the three scan line, then the dateout of selector 210 meeting selection deinterleave unit 208 is as the data of second scan line.
In the present embodiment, merge cells 212 merges second chromaticity sampling error and removes second scan line that first scan line that device 206 exported and selector 210 exported two scan lines with output output map field.Above-mentioned deinterleave is handled all scan lines that will repeat in present figure field F_current and is handled and export, and finally can obtain complete in fact deinterleave output map field.
