Abstract

When a reverse reproduction is instructed in an image reproducing apparatus (1), reproduced image data per picture generated by an MPEG video decoder (5) in a time series manner are inputted to an MPEG video encoder (6) so as to be recoded to I picture alone or B picture combined with I picture. An MPEG video decoder (7) reads out this recoded data sequence in a reverse time-series manner and decodes it successively, and displays a smooth reverse reproduced image. As the case may be, a data amount reducing circuit which reduces resolution and a data amount restoring circuit which restores the resolution are inserted in between. The reverse reproduction which is superior in ease of operation, cost merit, implemented area and so forth is realized.

Invention Description (1) [Technical Field] The present invention relates to a daytime image reproduction method and image processing method, and the use of these Method of image reproduction device, image processing device, and television camera. The present invention relates to a technology for reproducing or processing data encoded according to the MPEG (Moving Picture Expert Group) standard. [Technical background] Multi-media processing data has a huge amount of data and is of various types. It is necessary to implement high-speed processing of such data in the practical application of multimedia. In the high-speed processing of data, the compression and elongation technology of the data is indispensable. The compression and elongation technology of such materials is, for example, the "MPEG" method. This MPEG method is standardized by the MPEG Committee (ISO / IEC JTC1 / SC29 / WG11) under the ISO (International Organization for Standardization) / IEC (International Electro-technical Commission). Image processing devices using the MPEG method are installed in various image-related devices such as animation cameras, still cameras, televisions, video CD playback devices, and DVD playback devices. Using MPEG-processed image data as information about animation, the animation is composed of a plurality of frames in one second, for example, a frame of 30 frames, that is, a still picture or a drawing. As shown in Figure 1, the image data is sequence 6 of sequence (Sequence), GOP (Group Of Picture), picture (Picture), day slice (Slice), macro block (Macroblock), and block (Block). The hierarchical structure of the layers is formed. The number of daytime films that make up a frame is not necessarily the same as the number of macro segments that make up a picture. In Figure 1, the macro section layer and the paper size are applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 312045 I * ------ W ----------- --Order --------- line (please read the notes on the back before filling this page) 567722 91 A7 B7 V. Description of the invention (2) The section layer is omitted. In addition, MPEG mainly has two methods of MPeg-1 and MPEG-2 according to different coding rates. The frame according to MPEG-1 corresponds to the picture. According to MPEG-2, the frame or field can correspond to the picture. The two fields form a frame. The structure of the picture frame corresponding to the picture is called the frame structure, and the structure of the day field corresponding to the day surface is called the picture field structure. In MPEG, a compression technique called inter-frame prediction is used. The prediction between frames is to compress the data between the frames according to time. Inter-frame prediction is a prediction in both directions. The bidirectional prediction refers to a combination of forward prediction based on past reproduction day images or portraits to predict current reproduction portraits, and backward reproduction prediction from future reproduction images to present reproduction images. The above-mentioned bidirectional prediction has three types of daylight surfaces: I-picture (Intra-Picture), P-picture (Predictive-Picture), and B-picture (Bidirectionally Predictive-Picture). The I picture is a day image that has no relationship with past and future reproduction portraits, which is generated independently by the coding process in the day frame. In order to implement random access, at least one frame I picture is required in the GOP. All macro sections in the I picture are in the form of intra-frame prediction pictures (Intra Frame). The P-pictures are predicted in the forward direction through the inter-frame coding process, that is, they are generated through past I-pictures or P-picture predictions. The macro section in the p picture, including the prediction picture in the picture frame and the forward-looking day plane (Forward Inter Frame). The B picture is generated by performing bidirectional prediction by the inter-frame coding process. In the bi-directional prediction, the B picture is generated in any of the three prediction modes shown below.

Description of the invention (3) ① Forward prediction: from the past I-picture or P-picture prediction ② Reverse direction prediction: I-picture or P-picture prediction in the future ③ Bi-directional prediction ...- Prediction of macro sections in B-picture by past and future I-picture or P-picture There are four forms of in-frame prediction picture, forward prediction picture, backward prediction frame (Backward Inter Frame), and interpolated prediction frame (Interpolative Inter Frame). For the above-mentioned I, P, B pictures are all coded. That is, although j picture can be produced in the past and future. In contrast, P picture cannot be produced without past picture, and B picture cannot be produced without past or future picture. But for P picture and β picture , Like macro section, shape When the formula is an interpolated prediction picture, the macro section can also be generated without past or future pictures. When predicting between pictures, the I picture is generated periodically at first. Then the P picture is generated before the number of I pictures. The generated picture frame. The P picture is generated by prediction in one direction (forward direction) from the past to the present. Then, before the I picture is generated by the B picture, the picture frame is located after the P picture. When the B picture is generated, Among the three methods of forward prediction, reverse prediction, and bidirectional prediction, choose the most appropriate prediction method to use. For continuous animation, the current portrait is very similar to the previous and subsequent portraits, except for a small part. Therefore, it is assumed that The previous picture frame is the same as the next picture frame. If there is a change between the two picture frames, only the difference is extracted and compressed. For example, the previous picture frame is I picture, the second picture frame is ρ picture, and the difference is used as the data of B picture Extraction. The data between the frames can be compressed according to the time correlation. The data row or bit row (bit s) of the video data encoded according to the MPEG video part tream) is called MPEG image series.

Cangzheng r \ j Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (4) MPEG-1 mainly corresponds to Recording media such as video CD (CompactDisc) and CD-ROM (CD-Read Only Memory). MPEG-2 not only supports recording media such as video CD, CD-ROM, DVD (Digital Video Disc), and VTR (Video Tape Recorder), but also fully supports communication media including LAN (Local Area Network), terrestrial broadcasting, and Communication media such as satellite communications and CATV (Community Antenna Television). The core technology of the MPEG imaging department is Motion Compensated prediction (MC) and Discrete Cosine Transform (DCT). The encoding technology using MC and DCT is called Hybrid encoding technology. According to the MPEG image part, DCT (alias FDCT; Forward DCT) is used during encoding to decompose the image signal of the image into frequency components. Then in the complex code, the inverse transform of DCT (inverse discrete cosine transform; IDCT; Inverse DCT) is used to restore the frequency component to the image signal of the image. Although MPEG can handle a very large amount of data, as described above, because of the use of a compression technique called inter-frame prediction, data records recorded in accordance with the time series encoding of the MPEG image section are implemented for picture search. Reverse playback, that is, when the playback in the reverse direction is implemented, it cannot be like a normal video tape recorder, and it is very difficult to reproduce the recorded data list against the time axis. Therefore, conventionally, only the I pictures allocated to each GOP are reproduced against the time axis. As mentioned above, since the I picture is a portrait processed by coding in the frame, it is not necessary to refer to the previous and next pictures independently. ^ Paper size is applicable to China National Standard (CNS) A4 (210 X 297 male ~ 4 312 045 1 · ------------------- Order -------- -Line (Please read the phonetic on the back?

Description of the Invention (48) (i) As the modified side of the fifth embodiment, decoder 5 and encoder when reverse playback is implemented The processing of 6 maintains the same implementation form and only outputs the same picture repeatedly on the second decoder 7. This can reduce the power consumption of the decoder 5. (j) In the fifth embodiment and the above (i), the The number of times of repeated output of the same picture of the decoder 5 and the second decoder 7 is set to more than two times. Thus, a lower-speed reverse reproduction day surface can be obtained. 00 According to the fifth embodiment, the decoder 5 and the second decoder 7 are The structure of repeatedly outputting f decoded data, but when there is a merit in circuit control or timing control, it is laj- 〇 (l) to repeatedly decode the same picture and rotate it out in each embodiment. When reverse playback is performed, the frames recorded in the MPEG image sequence in the hard disk 4 are directly transferred to the memory area 4a without being processed by the decoder 5 and the encoder 6. Thus, the decoder 5 and the encoder 6 can be reduced. Power Consumption (m) In addition to 时 above, when reverse playback is performed, the b picture is not decoded. The processing by the encoder 5 and the encoder 6 is directly transferred to the memory field 乜. As a result, the power consumption of the decoder 5 and the encoder can be reduced. In addition, since all data is not re-encoded into j pictures, the memory field can be reduced 4 & However, at this time, the second decoder 7 must change the sequence of the front reference area and the rear reference area of the B picture read from the memory area to the order of the signal sequence to perform decoding.

Description of the invention (49) The high-speed reverse reproduction function described in the fourth embodiment is mounted on an image reproduction device, and operation keys for selecting the above functions are provided.逆 Reverse playback is performed for each frame in response to the operation of the operation keys.之外 Except for the embodiment described above 'An application having two encoding or decoding functions in one device has the following embodiments.

Description of the invention (50) When jumping to the index when approaching the scene. (Q) The data volume reduction circuit 300 may not be used to reduce the number of pixels, but may be used to implement a partition structure for the picture frame. This data amount reduction circuit 300, as shown in FIG. 21 (a), switches the original data of each picture generated by the decoder 5 or the common decoder 53 by switching the nodes of the data amount reduction circuit 300. Frame unit skips. For example, switching each frame of the node once will reduce the number of frames to 1/2, and skipping two frames across three frames will reduce the number of frames to 1/3. When the data amount reduction circuit 300 is configured as shown in FIG. 21 (a), the data recovery circuit 400 is shown in FIG. 21 (b), and stored in the second decoder 7 or The buffer memory 201 of the image data of each screen generated by the decoder 53 and the main control circuit 10 controlling its operation are constituted, and the data volume reduction circuit 300 is skipped, and the buffer memory 201 will be the same The image data is repeatedly output. Here, the data amount of the image data generated by the material recovery circuit 400 is different from the data amount of the image data before the data amount reduction circuit 300 reduces, but as described above, the second decoder 7 or the common The amount of data of the pictures and materials of each picture generated by the decoder 53 is close to or more than the amount of data of the pictures before the reduction, so it can be said that "substantial recovery" is obtained. (0) When reverse reproduction is implemented, it is necessary to save 1Gop of the portrait data in the memory area 4a as it is. Because in Gop, its data can only be read in the forward direction, so if 1GOP is not If all the data is retained, the reverse reproduction cannot be implemented. This is the reason for the capacity of the 1GOP portraits in the memory area 4a. It is the effective use of the above paper standards to apply the Zhongguan standard ϋ) Α4 Specifications ⑵〇X 297 mm) ------- 312045 l · -------------------- Order --------- line ( Please read the notes on the back before filling out this page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 567722, A7 _ _B7 l… —----- 5. I. Description of the invention (Si), In the first embodiment and the like, the encoder 6 is also allowed to move freely during the forward reproduction period, and 1 GOP copies of reverse reproduction data are often generated and held. This has the purpose of making the switch smooth when the forward switch is reversed. However, in this method, it is possible to realize a smoother transition of the regeneration direction than the state in which it is not allowed to move freely, but it does not cause any time delay when switching. Because when GOPn is subjected to reverse reproduction, it is necessary for the multiplexer 5 to read 1 GOP of encoded data to decode the previous GOPn-ι. The continuous processing may not be completed before the reverse reproduction of GOPn is completed. If it is not finished, the retrograde regeneration will temporarily stop at that time. The solution to the above problems can be expanded by saving the 1G0P image data described in the first embodiment. For example, when the maximum 2G0p image data is saved, it can be completely eliminated when switching from normal playback to reverse playback. Time delay. Therefore, if the above specifications are required, the above solutions can be applied. In this case, it is necessary to increase the memory capacity. When the I picture is re-encoded by the encoder 6, in order to control the memory capacity of storing these pictures, I pictures can be divided into two or three pictures, or the number of pixels can be reduced and compressed in various frames. deal with. First, when the I pictures are scattered and stored, the skipped pictures can be displayed again. For example, when skipping every other frame, all I pictures are displayed twice to keep the speed of reverse playback the same as the speed of normal playback. On the other hand, if the I-picture recorded every other frame is reproduced in its original state, it can be automatically reproduced at twice the speed. Of course, it may be considered as part of its product specifications.

V. Description of the invention (52) When reducing the number of pixels, it is also possible to perform the decoding in the form of a downconversion in the IDCT process of the decoder 7. For example, IDCT is usually implemented on a square block of 8x8 pixels, and it is also possible to implement a 567722 segment of 8x4 pixels. At this time, the capacity of the image data stored in the frame memory required for performing the image reproduction becomes 1/2, and as a result, the aforementioned 2GOP I pictures can be stored in the vacant area. In addition, when the above down conversion is performed, the portrait at 1960x1080 pixels in the high-definition mode becomes 9880x8080 pixels. Therefore, during reproduction, each pixel may be displayed twice in the horizontal direction, etc., and a resolution reproduction process may be performed. (S) When transitioning from reverse regeneration to forward regeneration, the time delay during the aforementioned switching should also be considered. Here too, the same measures as above can be taken, and the screen data to be read will be accumulated to the level of 1 to 2G0P. It is assumed that when the nth GOPn is read during the reverse reproduction, the picture data of the GOPn is maintained until the read of the reverse reproduction reaches two previous G0Pn 2. That is, the data of a certain GQp is held until two previous GOP data are read out, so that the seamless reproduction can be realized when switching to the normal reproduction. The switch from reverse playback to normal playback can be handled by the decoder 5 only. The time delay of the state of (r) is inherently small. Therefore, although the above is set to 2G0P, in fact, 1G0P should be sufficient. However, this value is different from the installation state of the device, so it is best to determine it by experiments and so on depending on the model. (t) Fig. 22 illustrates that the I-picture is stored in a cache memory to achieve a high-speed reproduction. I will focus on the I screen as a "recyclable screen". As shown in the figure, for the sake of simplicity, there are 6 frames on a 1 GOP screen. In the 3G0P frames from GC ^ to GOP3, GOPi is from L to b.

Description of the Invention (53) GOP2 is represented by 17 to B12 and GOP3 is represented by 113 to b18. Now suppose that GOP3 requires reverse reproduction, as described above, it is performed in the order of reading from g0j> 3 ①, reading from GOP2 0, and reading ③ from GOPi. Here, focusing on the processing of GOP2, in order to reproduce the last picture, the first picture of GOP3 is read. However, it can be seen that the picture ιΐ3 has been read out and decoded during the reverse reproduction of gop3. Therefore, if the decoded data of the first I picture of each Gop is cached in the memory area 4a or other memory before the processing of one GOP on the MPEG data row, the picture can be read out again in the province of IP. Processing. The application of the above-mentioned high-speed buffer can improve the processing efficiency during reverse regeneration. (u) In the above-mentioned several embodiments, the encoder 6 performs re-encoding to generate I-pictures', which are combined with B-pictures depending on the state, and are used for encoding data for backward reproduction. However, it is not necessarily limited to this. For example, the encoder 6 can generate more I pictures than the original I pictures included in the original MPEG video sequence, and other forms can also be formed by the industry's selection at the equipment stage. To put it another way, the encoder 6 may encode the portrait data into a picture row of a type that refers to other pictures with at least one frame for the same prediction direction. The “prediction direction” is the forward or reverse direction, and each indicates that it is a prediction from the past and a prediction from the future. Therefore, for the forward and reverse directions, it is also considered to refer to the picture of only the picture of 0 frame or 1 frame. For the current MPEG, the 1-picture and B-picture meet the conditions. The nature of the problem of which picture should be generated by re-encoding. As long as it is a structure required for normal playback, especially it can maintain the memory capacity to achieve reverse playback Just fine. According to MPEG, although the P picture has a reference in the forward direction, it is quite far from this paper.
