  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a configuration relating to video recording in a video camera 100 as an imaging apparatus incorporating a video playback apparatus according to an embodiment of the present invention. The lens unit 101 constituting the imaging optical system forms an object image by forming an image of light from the object. The imaging element (imaging means) 102 is constituted by a CCD sensor, a CMOS sensor, or the like, and photoelectrically converts (captures) a subject image formed by the lens unit 101. The analog signal processing unit 103 generates an analog image signal by performing processing on the analog signal output from the image sensor 102. The analog signal processing unit 103 includes, for example, a CDS (Co-related Double Sampling) circuit, an AGC (Automatic Gain Control) circuit, and the like. The camera signal processing unit 104 includes an A / D converter, and generates video data as a digital video signal from the analog imaging signal generated by the analog signal processing unit 103. The encoding unit 105 encodes the video data generated by the analog signal processing unit 103 in the MPEG2 format, and outputs an MPEG2 stream.

  The angular velocity sensor 111 detects an angular velocity of camera shake such as camera shake applied to the video camera 100. The angular shake amount calculation unit 112 integrates the output from the angular velocity sensor 111 and calculates an angular shake amount that is a camera shake amount. The time code setting unit 114 sets the time code at the time of video recording using the time information acquired from the clock 113. The metadata setting unit 115 outputs the angular shake amount, time code, and other data (not shown) as metadata.

  The recording control unit (recording unit) 121 records the MPEG2 stream from the encoding unit 105 and the metadata from the metadata setting unit 115 on the recording medium 122 in association with each other. As a result, the streamed video data and metadata as additional data including the angular shake amount as shake data that is data relating to shake (camera shake) during imaging for recording the video data are recorded on the recording medium. 122 is recorded. As will be described later, the recording control unit 121 can reproduce and output the MPEG2 stream from the recording medium 122, and can read arbitrary metadata.

  FIG. 2 shows a configuration related to video playback in the video camera 100, that is, a configuration as a video playback device. In this embodiment, the case where the video playback device and the video recording device are integrated to form a video recording / playback device (video camera) will be described. You may comprise with an apparatus different from a recording device.

  As described above, the MPEG2 stream to which the metadata including the angular shake amount is added is recorded on the recording medium 122. However, as long as the video camera 100 can acquire the angular shake amount and the video data in association with each other, any recording format may be used. For example, the metadata is recorded separately from the video data. Also good.

  The recording control unit 121 acquires an MPEG2 stream and metadata from the recording medium 122. The decoding unit 221 decodes the MPEG2 stream acquired by the recording control unit 121, and outputs the decoded video data (digital video signal) to the memory 222 together with the metadata. Video data is composed of a plurality of frames. Image data (unit image data) of each frame in the video data is referred to as frame image data. However, when one frame is composed of a plurality of fields, the unit image data may be the image data of the field.

  The memory 222 stores the decoded video data for several seconds, that is, a plurality of frame image data for several seconds. By storing frame image data for several seconds in the memory 222, it is possible to acquire the angular shake amount of the previous frame with respect to the frame being reproduced (displayed) output to the display unit 224. It becomes.

  The image processing unit 223 cuts out a cut-out area and a cut-out area having a cut-out size determined by the microcomputer 210 described later according to shake data from each of the plurality of frame image data. Then, electronic zoom processing for enlarging the image data (partial image data) of these cutout areas to a predetermined display size is performed to generate image stabilization image data, and the image stabilization image data is sequentially output to the display unit 224. The display unit 224 sequentially displays (reproduces) the input image stabilization image data. As a result, the vibration-proof reproduction of the video data is performed.

  The joystick 231, the play / pause button 232, and the stop button 233 are operation members operated by the user. Each operation member notifies the microcomputer 210 of an instruction (signal) corresponding to a user operation. Specifically, the joystick 231 operated to tilt up, down, left, and right notifies the microcomputer 210 an instruction to move a cursor for selecting an item on the display screen of the display unit 224 in the operation direction. The pressed play / pause button 232 notifies the microcomputer 210 of a video playback start instruction (playback instruction) and a pause instruction. The stop button 233 that has been pressed down notifies the microcomputer 210 of a video playback end instruction.

  A microcomputer (hereinafter referred to as a microcomputer) 210 includes a motion vector amount acquisition unit 201, a metadata reading unit 202, an angular velocity shake amount acquisition unit 203, a shake correction amount determination unit 204, a time code setting unit 205, and a read address setting unit 206. Including. The motion vector amount acquisition unit 201, the metadata reading unit 202, and the angular velocity shake amount acquisition unit 203 correspond to a shake data acquisition unit, and the shake correction amount determination unit 204 and the above-described image processing unit 223 correspond to an image stabilization reproduction unit.

  The motion vector amount acquisition unit 201 acquires a motion vector amount indicating video motion (image shake) between consecutive frame image data in the video data read from the memory 222. This motion vector amount is also shake data recorded in association with video data as data related to shake during imaging (more specifically, it is included in the video data itself). The metadata reading unit 202 reads the metadata of the read address set by the read address setting unit 206 described later from the metadata added to the video data from the memory 222.

  The angular shake amount acquisition unit 203 acquires the angular shake amount from the read metadata. Based on the motion vector amount from the motion vector amount acquisition unit 201 and the angular shake amount from the angular shake amount acquisition unit 203, the shake correction amount determination unit 204 is configured to reduce (correct) each frame image. Determine the cutout position and cutout size of the cutout area from the data. Then, the determined cutout position and cutout size are set in the image processing unit 223. The image processing unit 223 cuts out partial image data from each frame image data with the cut-out position and cut-out size determined for the frame image data, and generates image stabilization generated by electronic zoom processing at an enlargement ratio corresponding to the cut-out size. The image data is displayed on the display unit 224. As a result, image stabilization reproduction is performed in which an image is reproduced while performing image stabilization processing (image blur correction processing). In addition, when the cutout position and the cutout size are recorded in the metadata, the shake correction amount determining unit 204 acquires the cutout position and the cutout size via the metadata reading unit 202 and stores them in the image processing unit 223. Set.

  The time code setting unit 205 acquires the time code of the currently reproduced frame from the metadata reading unit 202, and notifies the read time setting unit 206 of a time code that is a predetermined time after the acquired time code. The read address setting unit 206 sets an address corresponding to the notified time code in the memory 222. As a result, the metadata reading unit 202 can acquire metadata of a frame that is reproduced after a predetermined time (that is, ahead of a predetermined time) after the currently reproduced frame.

  Further, the microcomputer 210 performs the processing shown in the flowcharts of FIGS. 3 and 4 together with the image processing unit 223. The flowchart of FIG. 3 shows the flow of a video playback process executed by the microcomputer 210 and the image processing unit 223 in accordance with a video playback program that is a computer program. In the following description and FIG. 3 and FIG. 4, “S” means a step. In the following description, video data, frame image data, and other XX image data are simply referred to as video, frame image, and XX image, respectively.

  In S301 to S305 shown in FIG. 3, the microcomputer 210 performs processing related to display of a selected image for selecting a video to be reproduced. In this embodiment, the selected image is a thumbnail image generated from a frame image of the first frame (first frame) of the video (a reproduction start image displayed first at the start of image stabilization reproduction: hereinafter referred to as the first frame image). . In S <b> 306 to S <b> 307, the microcomputer 210 performs processing related to the display of a stopped image when video reproduction is stopped. In S308 to S312, the microcomputer 210 performs processing related to display of a reproduced video.

  In this embodiment, it is assumed that N (N ≧ 1) videos V are recorded in advance and stored in the recording medium 122, and the nth (1 ≦ n ≦ N) video is denoted as V (n). . For the M (n) (M (n) ≧ 1) frame images F constituting the video V (n), the m-th (1 ≦ m ≦ M (n)) frame image is denoted by F (m). The cutout position of the cutout area of the frame image F (m) is written as P (m), and the cutout size is written as S (m). Also, a video to be reproduced among N videos V (n) is denoted as V (A). These notations are the same in the processing of FIG. 4 described later.

  First, in step S301, the shake correction amount determination unit 204 in the microcomputer 210 performs the extraction position P (1) and the extraction size S (1) in the first frame image F (1) of the video V (n) via the metadata reading unit 202. ) From the metadata. These are stored in a temporary memory (not shown) and the process proceeds to S304. However, if P (1) and S (1) are not recorded in the metadata (cannot be acquired from the metadata), the process proceeds to S302.

  In S302, the shake correction amount determination unit 204 determines a cutout position P (1) and a cutout size S (1) in the first frame image F (1) of the video V (n), and the P (1) and S ( 1) is stored in the temporary memory and the process proceeds to S303. Details of the determination process of P (1) and S (1) will be described later.

  In S303, the shake correction amount determination unit 204, via the metadata setting unit 115, extracts the cutting position P (1) and the cutting size S (1) in the first frame image F (1) of the video V (n) determined in S302. ) Is recorded in the metadata, and the process proceeds to S304.

  In S304, the shake correction amount determination unit 204 stores the cutout position P (1) and the cutout size S (1) of the cutout area in the first frame image F (1) of the video V (n) stored in the temporary memory in S301 or S302. ) And these are set in the image processing unit 223. As a result, an image generated by enlarging the partial image cut out from the first frame image F (1) of the video V (n) through the image processing unit 223 (however, the display size is small) is displayed as a thumbnail image that is the selected image. Displayed on the part 224. The selected image is the same image (however, the display size is small) as the anti-vibration image or the non-anti-vibration image according to the result of the determination process of P (1) and S (1) described later. Thereafter, the microcomputer 210 proceeds to S305.

  In S305, the microcomputer 210 determines whether or not all N selected images of the video V are displayed on the display unit 224. If all the selected images of the video V are displayed on the display unit 224, the process proceeds to S306. move on. On the other hand, if all the selected images of the video V have not been displayed on the display unit 224, the microcomputer 210 returns to S301, and performs the processing of S301 to S304 again for the next video V (n + 1).

  In S306, the microcomputer 210 determines whether or not a selection image of the video V (A) to be reproduced is selected by a user operation of the joystick 231. If selected, the process proceeds to S307. If not selected, the microcomputer 210 performs the process of this step again.

  In S307, the shake correction amount determination unit 204 acquires the extraction position P (1) and the extraction size S (1) in the first frame image F (1) of the video V (A) stored in the temporary memory in S301 or S302. These are set in the image processing unit 223. As a result, an image generated by enlarging the partial image cut out from the first frame image F (1) of the video V (A) is displayed on the display unit 224 through the image processing unit 223 as a stop image. The stop image is the same image (with the same display size) as the anti-vibration image or the non-anti-vibration image depending on the result of determination processing of P (1) and S (1) described later. Thereafter, the microcomputer 210 proceeds to S308.

  In S <b> 308, the microcomputer 210 determines whether or not an instruction to end playback of the video V (A) is given by a user operation of the stop button 233. If an instruction to end reproduction is given, the microcomputer 210 proceeds to S301 and performs again the processing related to the display of the selected image in S301 to S305. If the reproduction end instruction has not been given, the microcomputer 210 proceeds to S309.

  In S <b> 309, the microcomputer 210 determines whether or not an instruction to start playback of the video V (A) has been given by the user operation of the playback / pause button 232. If the reproduction start instruction is given, the microcomputer 210 proceeds to S310. If a playback start instruction has not been given (or a playback pause instruction has been given), the process proceeds to S308.

  In S310, the shake correction amount determination unit 204 sets the extraction position P (m) and the extraction size S (m) in the frame image (reproduction frame image) F (m) of the frame currently reproduced in the video V (A). The P (m) and (m) are stored in a temporary memory, and the process proceeds to S311. Details of the determination process of P (m) and S (m) will be described later in the same manner as S302.

  In S311, the shake correction amount determination unit 204 acquires the cutout position P (m) and the cutout size S (m) in the playback frame image F (m) of the video V (A) stored in the temporary memory in S310. Is set in the image processing unit 223. As a result, a playback image generated by enlarging the partial image cut out from the playback frame image F (m) of the video V (A) is displayed on the display unit 224 through the image processing unit 223. Thereafter, the microcomputer 210 proceeds to S312. The reproduced image becomes a vibration-proof image or a non-vibration-proof image according to the result of determination processing of P (m) and S (m) described later.

  In S312, the microcomputer 210 determines whether or not the clipped areas of all the frame images F (1 to M (A)) in the video V (A) are displayed as playback images. When all the reproduced images are displayed, the microcomputer 210 proceeds to 301 and performs again the processing related to the display of the selected image in S301 to S305. If all the reproduced images are not displayed yet, the microcomputer 210 proceeds to S308, and performs the processing of S308 to S312 again for the next frame image F (m + 1).

  In the flowchart of FIG. 4, the cutout position and cutout size of the cutout region from the frame image performed by the shake correction amount determination unit 204 together with the motion vector amount acquisition unit 201 and the angular shake amount acquisition unit 203 in S302 and S310 of FIG. A determination process (that is, an image stabilization process) is shown. As described above, when the m-th (1 ≦ m ≦ M (n)) frame image of the frame image F is expressed as F (m), m in S302 is 1, and m in S310 is 1 ≦ m ≦ M. It is.

  In S401, the motion vector amount acquisition unit 201 acquires a motion vector amount for a predetermined period from the frame image F (m) of the video V. Similarly, the angular shake amount acquisition unit 203 acquires the angular shake amount for the predetermined period from the frame F (m) of the video V via the metadata reading unit 202. Since camera shake due to camera shake usually has a frequency of 4 to 9 Hz, the predetermined period is, for example, about 0.5 seconds corresponding to about 2 cycles of 4 Hz.

  In step S <b> 402, the shake correction amount determination unit 204 determines whether panning of the camera 100 has been performed within a predetermined period. Specifically, the shake correction amount determination unit 204 increases or decreases the motion vector amount or the angular shake amount for a predetermined period acquired in S401 in one direction exceeding a predetermined threshold within the predetermined period. It is determined that panning has been performed. If the shake correction amount determination unit 204 determines that panning has been performed, the process proceeds to S404. If it is determined that panning has not been performed, the process proceeds to S403. During panning, the amount of motion vector and the amount of angular deflection generally increase, and the cutout position of the cutout area reaches the limit position (cutout end position). For this reason, the shake correction amount determination unit 204 that has determined that panning has been performed performs control to stop the image stabilization process being played back. Note that panning may include not only the 100 horizontal angular displacement of the camera but also the vertical angular displacement (also referred to as tilting).

  In S403, the shake correction amount determination unit 204 in the frame image F (m) for performing the image stabilization process on the reproduced video V based on the motion vector amount or the angular shake amount for the predetermined period acquired in S401. The cut position P (m) and the cut size S (m) of the cut area are determined.

  In S <b> 404, the shake correction amount determination unit 204 determines the cutout position P (m) and the cutout size of the cutout area in the frame image F (m) so that the image stabilization process is not performed (stopped) on the video V being played back. S (m) is determined as a predetermined cutting position and a predetermined cutting size. In the present embodiment, the shake correction amount determination unit 204 determines the extraction position P (m) and the extraction size S (m) for the frame image F (m), and the extraction position P for the previous frame image F (m−1). (m-1) is determined to be the same as the cut-out size S (m-1). Further, the shake correction amount determination unit 204 determines the cutout position P (m) so that the center area of the head frame image F (1) is cut out as the cutout area for the head frame image F (1). Further, for the first frame image F (1), the cut-out size S (m) of the cut-out area in the frame image F (m) is determined based on the motion vector amount or the angular shake amount corresponding to the threshold used in S402. In these cases, an image generated by being cut out from the frame image F (m) (including the first frame image F (1)) and enlarged is a non-vibration-proof image.

  Next, an example of image display in the present embodiment will be described using FIGS. 5A to 5C and FIGS. FIG. 5A shows an example of a conventional selection image, FIG. 5B shows an example of a conventional stop image, and FIG. 5C shows an example of a conventional reproduction image displayed immediately after the start of reproduction. . In FIG. 5A, the first frame image of the video read from the recording medium is displayed as it is as the selected image. In other words, this selected image is not cut out from the top frame image and enlarged. When a video is selected through the selected image, a stop image of the video is displayed as shown in FIG. 5B. At this time, the first frame image is not cut out and enlarged. Is displayed as a stop image.

  Then, as shown in FIG. 5 (C), immediately after the start of video playback from the display state of the stop image, a playback image is displayed as an image in which the cut-out area from the top frame image has been expanded by the image stabilization process. The Therefore, the angle of view of the stop image shown in FIG. 5B and the angle of view of the reproduced image shown in FIG.

  On the other hand, FIG. 6A shows the selected image in the present embodiment, FIG. 6B shows the stop image in the present embodiment, and FIG. 6C shows the display immediately after the start of reproduction in the present embodiment. An example of a reproduced image is shown. In FIG. 6 (A), a cutout cut out from the first frame image F (1) of the video read from the recording medium at the cutout position P (1) and cutout size S (1) determined by the image stabilization process. The image of the area is enlarged and displayed as a selected image. When a video is selected through this selected image, a stop image of the video is displayed as shown in FIG. Also in this case, the image of the cut-out area cut out with the cut-out position P (1) and the cut-out size S (1) determined by the image stabilization process from the top frame image F (1) is enlarged and displayed as a stop image.

  Then, as shown in FIG. 6C, immediately after the start of video playback from the display state of the stop image, the cropping position P (1) and the cropping size S ( The image of the cutout area cut out in 1) is enlarged and a reproduced image is displayed. Therefore, the angle of view of the stop image shown in FIG. 6B is the same as the angle of view of the reproduced image shown in FIG. 6C.

  In the present embodiment described above, when performing vibration-proof reproduction of a recorded video, a selection image for allowing the user to select a video and a stop image that is displayed after the video is selected until playback is started are displayed. The image has the same angle of view as the reproduction pixel displayed immediately after the start of reproduction. For this reason, it is possible to prevent an unnatural change in the angle of view from the display state of the stop image before the start of video playback to immediately after the start of playback.

  In this embodiment, the case where the image generated from the first frame image of the reproduced video is used as the reproduction start image has been described. However, the reproduction start image is not necessarily limited to the image generated from the first frame image. For example, when video playback is stopped at an intermediate frame other than the first frame, an image generated from the frame image of the intermediate frame may be used as a playback start image and used as a stop image or a selected image.

The video playback process in the video camera 100 has been described. However, similar video playback processing is performed by various devices having video playback functions such as digital cameras, personal computers, PDAs, mobile phones, portable image viewers, printers with displays, digital photo frames, music players, game machines, electronic book readers, and the like. It is applicable to.
