BACKGROUND OF THE INVENTION
The present invention relates to an image reproducing apparatus using a buffering method for temporarily storing still image data and moving image data.
[0002]
[Prior art]
As an image reproducing apparatus having a function of reproducing digital data such as a photographed image and a created image, for example, a digital camera or the like can be cited. Such an image reproducing apparatus may be one in which digital data is managed by a recording unit incorporated in the apparatus itself, one in which data is managed by reading / writing on a removable recording medium, or one which is managed via a network. There are various forms. In recent years, due to dramatic progress in hardware, moving image data having a larger amount of data than that of still image data has been handled. When reproducing the moving image data, the moving image data is read from the recording unit in which the moving image data is recorded into the memory based on a reproduction instruction in the image reproducing device, and is reproduced on the display screen of the image reproducing device. Done. The time from the reproduction instruction until the moving image data is displayed on the display screen is referred to as “reproduction start waiting time”. In a small apparatus such as a digital camera, for example, the moving image recorded in the recording unit Since the amount of image data is large, it takes a lot of time for data transfer and data compression / decompression processing of moving image data. As a result, the “reproduction start waiting time” becomes very long, and the user displays the moving image data. I had to wait for a while.
[0003]
As an invention for shortening the reproduction start waiting time, there is one disclosed in an open patent publication (Japanese Patent Laid-Open No. 7-30838). According to the present invention, a scene or cut of moving image data is used as a delimiter unit, a reproduction start position of each unit is registered as an index, and one piece of moving image data recorded in a recording unit based on the registered reproduction start position. The address information of the video data and the subsequent moving image data is read into the buffer memory, and the desired scene can be reproduced immediately by designating the start address from the pre-registered index. is there.
[0004]
[Problems to be solved by the invention]
However, in this method, since an index of a moving image to be displayed must be created in advance and registered in the image reproduction apparatus, it is not possible to display an unregistered image at high speed. In addition, when there are multiple pieces of moving image data to be displayed, the amount of moving image data to be read is reduced due to the limitation of the buffer memory capacity. The playback start waiting time is hardly shortened. Furthermore, in order to avoid this, it is necessary to use a large-capacity buffer memory, and the apparatus itself becomes large and expensive.
[0005]
Therefore, the present invention is suitable for downsizing, and an object of the present invention is to provide an image reproducing apparatus that shortens the reproduction start waiting time even when there are a plurality of moving image data to be selected for reproduction.
[0006]
[Means for Solving the Problems]
  In order to solve the above problems, the present invention is configured as follows. That is, according to one aspect of the present invention, image data including representative image data and a plurality of image data associated with the representative image data supplied from a recording medium built in the recording medium or a recording medium attached to the self. An image reproduction device for reproducing at least image data of the image data group among a group or single image data, the representative image data andBeforeAt least one of the single image dataPaintingImage dataAnd image data adjacent to this image data in the display reproduction orderTemporary storage means for temporarily storingSaidDisplay from representative image data or single image data temporarily stored.ImageImage selection means for selecting data andWhen new image data is selected by the image selection means, image data having a display reproduction order close to the new image data is selected from the image data stored in the temporary storage means. Instead of image data with a distant display / playback order.Storage control means for controlling the storage.
  When the new image data is representative image data, the storage control means sets the image data of the image data group associated with the representative image data as data in a display / reproduction order, and the new image data In the case of single image data, it is possible to control to store other single image data or representative image data having a display / reproduction order close to the single image data as image data having a display / reproduction order close desirable.
Further, when the selected image immediately before the new image data is selected is representative image data, the storage control means displays and reproduces the new image data in the image data group associated with the representative image data. When the selected image immediately before the new image data is selected is rewritten from the image data with a long order and the new image data is selected, it is another single image data with a long display / reproduction order. It is desirable to control to rewrite from image data or representative image data.
[0007]
  The image data group may be a collection of image data constituting a moving image. With this configuration, the image data group of the selected representative image data can be read into the temporary storage unit before the image data group is reproduced by the reproduction instruction.
[0008]
  In addition, if frame information related to date and time and shooting order is added to each image data of the representative image data and the single image data, it is possible to select image data based on the date and shooting order. Further, the temporary storage means is a single image data which is the image data selected by the image selection means and the image data and the order of image selection before and after (the order of arrangement of the image data selected by the image selection means). Alternatively, the first storage area for temporarily storing the representative image data and the single image data or the representative image data excluding the image data temporarily stored in the first storage area, or the first storage area And a second storage area for temporarily storing a group of image data associated with the temporarily stored representative image data. In this configuration, the representative image data and the single image are stored. Each piece of image data includes frame information related to date / time or shooting order, and the storage control means selects the image data group by the image selection means prior to reproduction of the image data group according to the reproduction instruction. The selected representative image data and the single image data or the representative image data having the frame information adjacent to the representative image data are controlled to be stored in the first storage area, and the selected representative image data is stored in the selected representative image data. It may be configured to control to store the associated image data group in the second storage area.
[0009]
  With this configuration, in the previous configuration, the image data selected by the image selection unit and the image data whose image selection order comes before and after the image data are secured in a predetermined storage area of the temporary storage unit. It is possible to pre-read other storage areas with image data or a group of image data related to the selected image data. In the latter configuration, the image data selected by the image selection means and each image data If the selected image data is representative image data, the image data group of the representative image data can be stored in the other storage. It becomes possible to pre-read the area.
[0010]
  According to another aspect of the present invention, at least one of image data consisting of representative image data and a plurality of image data associated with the representative image data, or single image data is displayed. An image reproduction device, wherein the image data is at least one of representative image data or single image data among the representative image data, the image data group, or the single image data.And the image data adjacent to the representative image data in the display reproduction orderTemporary storage means for temporarily storingSaidDisplay from temporarily stored representative image data or single image data.DoImage selection means for selecting image data and whether the type of the selected image data is representative image data or single image dataDepending on,Storage area of the temporary storage meansTo control data update between newly stored image data and deleted image dataAnd a storage control means.
[0011]
With this configuration, image data related to the selected image data is always temporarily stored in the temporary storage means. Therefore, for example, reproduction of image data groups or selection of image data by a predetermined agreement can be performed. You can go smoothly. Further, the temporary storage method can be based on a priority order provided in or provided by the temporary storage means, for example, frame number order or photographing order.
[0012]
Each image data of the representative image data and the single image data has frame information related to date and time or shooting order, and the storage control unit is adjacent to the selected image data and the frame information. The representative image data or single image data to be stored may be controlled to be stored in a storage area with a high selection priority order adjacent to the selected image data.
[0013]
With this configuration, image data in which the frame number order or the shooting order is adjacent to the selected image data is always stored in a storage area with a high selection priority.
Further, when the selected image data is representative image data, the storage control means selects an image data group associated with the representative image data from a storage area having a low selection priority in order of reproduction of the image data group. You may make it memory-control.
[0014]
By configuring in this way, the order of storage control in the image data group is delayed as the storage area has a higher selection priority.
Each of the image data of the representative image data and the single image data has frame information related to date and time or shooting order, and the storage control means is configured such that the selected image data is a single image data. In this case, a single image data or representative image data in the selection order based on the piece information may be stored and controlled in order from a storage area having a high selection priority.
[0015]
By configuring in this way, the image data in the selection order based on the piece information is stored in the storage area with the high selection priority order.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram for each type of digital data handled in the present embodiment. The nth (n is a natural number) still image data (1-1 in the figure) consisting of a single image data, and a representative example. This is divided into n-th moving image data (1-2 in the figure) composed of image data and a plurality of chunks C (n) l (l is a natural number) related to the image data. Here, the chunk C (n) l represents a predetermined number of consecutive frames of image data (frames) constituting the moving image data as one unit, and in (1-2-1) in the figure. An example in which frames 1 to p (p is a natural number) related to the representative image data n are summarized as C (n) 1 is shown.
[0017]
FIG. 2 shows an example of a buffer management method in the embodiment of the present invention. (2-1) in the figure shows still image data currently selected for easy understanding of the data arrangement in the case where display image data that is still image data or representative image data is read into the buffer memory. An image is displayed on the assumption that the frames are arranged in the order of frame feeding (the one surrounded by a thick line in the figure), and the control method for the buffer memory will be described below using this image. The currently selected still image data refers to, for example, still image data currently displayed on the display screen of the image display device, and the frame advance order is added to, for example, display image data. A predetermined order in which the display image data is displayed on the display screen in order based on the frame information indicating the date and time and the shooting order is shown, and the symbol n (frame number) in the figure corresponds to this.
[0018]
In (2-1) in the figure, the selected still image data n is arranged at the center of the frame advance sequence, and above and below the display image, the still image data n and the frame advance sequence are adjacent. The display image data is arranged (read) in order from the data, and the frame number of the display image data is counted up in the downward direction of the figure, and for example, the display image data captured in that direction is counted. The date and time can be arranged so as to be new or arranged so as to be old. In this figure, the symbol m is a natural number.
[0019]
The selection is shifted from the selected nth still image data to the (n + 1) th display image data in the latest frame advance direction. At this time, when the newly selected display image data n + 1 is still image data, the still image data n + 1 is displayed at the center of the frame advance order arrangement, and the disposition of the frame advance order is the farthest. The image data is deleted, and instead, the display image data having a relationship closer to the display image data in which the arrangement of the frame advance order is deleted is read into the deleted storage area. That is, as shown in (2-2) in the figure, the display image data nm having the furthest frame arrangement is deleted from the still image data n + 1, and the display image arrangement having a frame advance arrangement closer to that is deleted. Image data n + m + 1 (position (1)) is newly read.
[0020]
Also, when the selection is shifted from the n-th still image data selected in (2-1) in the figure to the display image data n + 1 in the latest frame advance direction, and this display image data is representative image data. The storage area other than the storage area for storing the representative image data n + 1 and the still image data n and the display image data n + 2 for which the frame advance order is closest to the representative image data n + 1, The selected image data n + 1 is rewritten with moving image data relating to the representative image data n + 1 in order from the display image data having a distant relationship with respect to the frame advance order. That is, as shown in (2-3) in the figure, the selected representative image data n + 1 is stored while retaining the storage of the representative image data n + 1 and the most recent still image data n and display image data n + 2. The order indicated by the circled numbers in the figure starting from the storage area that stores the display image data nm having the disposition of the frame advance order as viewed from the center (only 4 is shown in the figure) In the same manner, the processing from the fourth to the corresponding destination is continued until the corresponding destination, and the display of the circled numbers is also treated in the same manner from this example onward.
[0021]
As shown in (2-2) of the figure, the display image data (display image data nm and display image data n + m) at both ends shown in (2-1) of the figure is in frame advance order. In this respect, the relationship is adjacent to each other (the display image data nn after the display image data n + m), and the above control method can be applied to, for example, a ring buffer in which the head and end of the address are connected in a ring shape. It can be applied to the following embodiments.
[0022]
The buffer management method described above will be described with reference to FIG. (3-1) in the figure is currently selected in the same manner as (2-1) in the figure for easy understanding of the data arrangement when display image data and chunks are read into the buffer memory. The image is displayed on the assumption that still image data is arranged in the frame advance order.
[0023]
In (3-1) in the figure, the selected representative image data n is arranged at the center when the display image data is arranged in the frame advance order, and the representative image data n and the frame advance order are arranged above and below it. Display image data n-1 and display image data n + 1 having the most recent arrangement are arranged (read), and the frame number of the display image data is counted up in the downward direction of the figure. For example, the display image data can be arranged so that the photographing date / time of the display image data is new or old. Further, in (3-1) in the figure, chunks related to the selected representative image data n are read on both sides of the three display image data. That is, it is assumed that n is replaced with n-1 in (2-3) of FIG.
[0024]
The selection is shifted from the selected nth representative image data to the (n + 1) th display image data. At this time, if the newly selected display image data n + 1 is still image data, the chunks read in the buffer memory are deleted in order from the storage area in which the chunks that are slower to play back the video are stored. The still image data n + 1 is arranged in the deleted storage area in order from the image data for display not in the buffer memory because the arrangement of the frame advance order is close to that of the still image data n + 1. That is, as indicated by the circled numbers in (3-2) in the figure, the display image data n + 2, n + 3, n + 4, n-2,... Are replaced with chunks in this order.
[0025]
If the selection is shifted from the n-th representative image data selected in (3-1) in the figure, and the newly selected n + 1-th display image data is representative image data, the representative image is displayed. Storage areas for the data n + 1 and the representative image data n and the display image data n + 2 that have an immediate relationship with the frame advance order are secured, and a storage area other than the storage area storing these is selected. The moving image data belonging to the representative image n + 1 is rewritten in order from the chunk with the fastest reproduction. That is, as shown in (3-3) in the figure, the latest chunk of the reproduction order belonging to the representative image data n is stored while retaining the representative image data n + 1 and the latest representative image data n. The stored storage area is rewritten with the other most recent display image data n + 2, and further, the storage area storing the slower chunks belonging to the representative image data n belongs to the selected representative image data n + 1 in order. Rewrite in the earlier chunk of the playback order. Note that the chunk arrangement indicated by (3-3) in the figure corresponds to the frame order and the rewrite order in the case where the display image data is arranged, and (3-1) and (3-3) in the figure are shown. ) In the order of chunk arrangement.
[0026]
FIG. 4 is a block diagram showing a digital camera as an example of an image reproducing apparatus that realizes the buffer management described above. Each block shown in this figure is configured as follows.
Reference numeral 401 denotes a power supply unit that distributes power to each unit of the camera. This power supply is supplied from a camera battery such as a dry battery or a rechargeable battery indicated by 402. A CPU (Central Processing Unit) 403 controls each part of the camera. The CPU 403 instructs the power supply unit 401 to distribute power to each part of the camera, uses various operations by the operation unit 404, for example, a release operation using a release button (not shown), a mode setting switch, and a menu screen. Performs control processing to execute arithmetic processing for received commands and pass the calculation result to a predetermined part, such as giving an instruction to the target part based on a mode setting operation or an image selection switching operation using a frame selection switch. . A strobe light emitting unit 405 emits a strobe at a predetermined timing under the control of the CPU 403. A photographing lens system 406 shows a photographing lens system including a zoom lens, a focus lens, and the like. A subject image that passes through these lenses and is combined at a light receiving surface of the photographing lens system 406 is converted into an electric signal by an image sensor 407. Converted. The subject image converted into an electrical signal by the image sensor 407 is subjected to processing such as AGC (auto gain control) in the image pickup circuit 408 under the control of the CPU 403. The A / D conversion circuit 409 converts the subject image into a digital signal via the imaging circuit 408. The detachable memory 410 is a detachable recording medium such as a solid-state memory card or a small hard disk device, and various digital data are read and written via the I / F unit 411 under the control of the CPU 403. The image display LCD 412 is a display screen such as a liquid crystal display for displaying digital data of a subject image being photographed and read digital data such as still image data and moving image data recorded in the removable memory 410. The digital data is displayed via the video memory 413 that temporarily stores various digital data to be displayed on the image display LCD 412 and the video output circuit 414 that outputs the digital data as a video. The digital data output by the video output circuit can be displayed on an external monitor other than the image display LCD 412. Further, communication with other external devices can be performed via the external I / F unit 415. The buffer memory 416 is composed of, for example, a DRAM or the like, and is a random access memory that temporarily stores various digital data read from the removable memory 410. The flash memory 417 is a memory in which a control program for causing the CPU 20 to control each part of the digital camera, data for performing various processes, and the like are stored. Under the control of the CPU 403, the compression / decompression unit 418 compresses digital data read / written from the removable memory 410 by, for example, JPEG (Joint Photographic Experts Group) system, or performs decompression processing.
[0027]
FIG. 5 is an example of a flowchart illustrating the operation of the buffer management method shown in FIG. 2, and this figure will be described below.
First, the CPU 403 checks whether the display image data on the buffer memory 416 selected based on the operation unit 404 is representative image data or still image data (S501). In the case of image data, a storage area on the buffer memory 416 in which the arrangement of the frame advance order is closer to the still image data that is the display image data in a state where rewriting by this selection has not yet been performed is specified. (S502). Then, it is checked whether or not the same display image data as the frame advance order is stored in the storage area on the designated buffer memory 416 (S503), and if it is the same, the process returns to step S502 to arrange the frame advance order. Performs processing on the storage area on the buffer memory 416 having the second closest relationship. If the check results in step S503 are not identical, the display image data for that frame number is extracted from the removable memory 410, the storage area is rewritten with this display image data (S504), and the flow returns to step S502. Processing is performed on the storage areas on the buffer memory 416 having the second closest relationship in the order of sending. Thereafter, the processing from step S502 to step S504 is repeatedly executed for all the storage areas on the buffer memory 416, and the process ends when the entire storage area on the buffer memory 416 is made.
[0028]
If the display image data is representative image data in step S501, the display image data and the frame advance order are the display image data in an empty state or a state where rewriting by this selection has not yet been performed. A storage area on the buffer memory 416 that is more distant is designated (S505). Then, it is checked whether the storage area on the designated buffer memory 416 is the display image data or the display image data before and after the frame advancement arrangement (S506). Then, the chunk with the earlier playback order of the moving image data associated with the selected representative image data is extracted from the removable memory 410, the storage area is rewritten with this chunk (S507), and the process returns to step S505. In step S506, if any of the above is true, the process ends.
[0029]
FIG. 6 is an example of a flowchart illustrating the operation of the buffer management method shown in FIG. 3, which will be described below.
Since the processing from step S501 to step S504 shown in this flow is the same as the processing described with reference to FIG. 5, detailed description thereof is omitted here. Therefore, the processing shown after symbol B will be described below. If the display image data is the representative image data in step S501, the display image data adjacent to the representative image data selected by the operation unit 404 in terms of frame advance order is stored on the buffer memory 416. An area is designated (S601). It is checked whether or not the display image data is stored in the designated storage area (S602). If the display image data is not stored, the display image data is extracted from the removable memory 410, and The recording area designated in step S601 is rewritten with the extracted display image data (S603). Then, as the processing after the end of step S603 and the processing in the case where the display image data is stored in the designated storage area in step S602, the same processing as that after the symbol A shown in FIG. 5 is executed. .
[0030]
Note that the buffer management method shown in FIGS. 2 and 3 may be irregularly performed depending on the frame arrangement of various types of display image data (still image data or representative image data). In this case, FIG. In step S501 and step S601, a step is newly provided for determining whether the type of display image data selected immediately before the representative image data designated this time is still image data or representative image data. If it is still image data, step S505 and subsequent steps may be executed, and if it is representative image data, step S601 and subsequent steps may be executed.
[0031]
Next, the timing for performing the buffer management will be described according to the processing of the CPU 403 in FIG. In a state where various display image data (still image data or display image data) is read on the buffer memory 416, selection is made from the currently selected display image data to display image data selected according to the frame advance order. Is detected (S701), the type of the detected display image data is checked (S702). If the display image data is representative image data, the representative image data is displayed on the image display LCD 412 via the video memory 413 and the video output circuit 414 (S703), and the above-described buffer management method, that is, (( 2-3) or individual chunks of moving image data recorded in the removable memory 410 by the method described in FIG. 3 (3-3) is read into the buffer memory 416 (S704). Subsequently, when an instruction to reproduce moving image data related to the selected representative image data, for example, a moving image reproduction instruction button (not shown) of the operation unit 404 is input (S705), the moving image data is reproduced. Reproduction is performed on the image display LCD 412 via the video memory 413 and the video output circuit 414 from the chunk with the earlier reproduction order read into the buffer memory 416 (S706). In addition, after step S704, other input commands are made instead of playback instructions (S707), and when the input commands are selection switching of display image data, the processing from step S701 is performed in the same manner as described above. If it is other than the selection switching of the display image data, this process is terminated, and a process based on the input command is executed (S708).
[0032]
If the check result in step S702 is still image data, the still image data is displayed on the image display LCD 412 (S709), and the buffer management method described above, that is, (2-2) in FIG. The display image data recorded in the removable memory 410 is read onto the buffer memory 416 by the method described in 3-2) (S710). If the subsequent input command (S711) is selection switching of display image data, the processing from step S701 is performed in the same manner as described above, and if the input command is other than display image data selection switching, this processing is terminated. Then, processing based on the input command is executed (S712).
[0033]
5, 6, and 7 are described on the assumption that various display image data have been read into the buffer memory. In this read state, for example, image selection switching is performed from the operation unit 404. By selecting the mode, it can be established by instructing the CPU 403 to read the display image data designated in the initial setting in advance and the display image data adjacent to this data from the removable memory 410 to the buffer memory 416. .
[0034]
In the above description, the two display image data immediately adjacent to the selected display image data are always held on the buffer memory 416. However, the number is not limited to two, and a predetermined number of adjacent additional display image data is held. You may make it make it.
FIG. 8 shows a display example when still image data and moving image data are displayed on the image display LCD of the digital camera. In the figure, reference numeral 801 denotes an operation unit 404, 802 denotes a viewfinder, and 803 denotes an image display LCD 412.
[0035]
(A) of this figure is a display example of moving image data. As shown in the image display LCD 412, an icon and a shooting mode indicating moving image data are shown in the upper right, a playback time and frame number are shown in the lower right, In the lower left, the number n of the moving image data may be displayed so as to overlap the reproduced image of the moving image data.
[0036]
(B) of this figure is a display example of still image data. As shown in the image display LCD 412, the shooting mode is superimposed on the upper right, and the frame number n of the still image data is superimposed on the reproduced image of the still image data on the lower left. May be displayed.
As described above, in the embodiment of the present invention, all or part of the moving image data is read into the buffer memory before the moving image data is instructed to be reproduced, so that the reproduction waiting time after the reproduction instruction is drastically reduced. Is done.
[0037]
Further, since the display image data whose frame order is adjacent to the selected still image data is read into the buffer memory, the selection of the frame order of the display image data becomes smooth.
Further, since the display image data whose frame number order is more adjacent to the selected display image data is always read into the buffer memory by a predetermined amount, the movement selection of the adjacent display image data can be performed smoothly. The
[0038]
In addition, when the selection is transferred to the representative image data in the state where the display image data has been read on the entire buffer memory, the buffer memory is rewritten with the chunk of the moving image data, but the selected representative image data Since the frame order is rewritten from a distant relationship, the display image data whose frame order is adjacent to the selected representative image data when the selection is switched before all the rewriting by the chunk is completed. Many of the images remain without being rewritten, and a wide range of frame order of display image data can be selected smoothly.
[0039]
【The invention's effect】
As described above, according to the present invention, the image data group of the selected representative image data can be pre-read into the buffer memory before reproduction, and the reproduction start waiting time for the image data group is drastically reduced. .
[0040]
Since the reading of the image data group into the buffer memory is after selection, the reproduction start waiting time is shortened even when there are a large number of image data groups.
Furthermore, image data groups such as single image data and moving images can be managed in the same buffer memory, and a storage area for image data to be selected by the image selection means can always be secured, so High-speed selection and reproduction of image data can be realized even with an inexpensive apparatus.
