[First Embodiment]
FIG. 1 is a block diagram showing a hardware configuration of an example of an image reproducing apparatus according to the first embodiment of the present invention.

  The illustrated image reproduction device 100 is an imaging device such as a digital camera, for example, and continuously reproduces and displays a plurality of images such as moving images. Then, a recording medium 200 such as a memory card is detachably attached to the image reproduction apparatus 100. In the recording medium 200, for example, image data such as moving image data obtained as a result of photographing is recorded as so-called image encoded data.

  The image reproducing apparatus 100 includes a DRAM (Dynamic Random Access Memory) 101, and the DRAM 101 is used as a main memory. The DRAM 101 temporarily stores image data obtained as a result of shooting, image encoded data read from the recording medium 200, and the like.

  The subject detection unit 103 detects a subject region (hereinafter also simply referred to as a subject) in the image data temporarily stored in the DRAM 101.

  The subject authentication unit 104 extracts the feature amount in the subject area detected by the subject detection unit 103 as first subject feature information. Then, the subject authentication unit 104 compares the registered subject feature information (also referred to as second subject feature information) registered in advance with the first subject feature information, and obtains the similarity. Subsequently, the subject authentication unit 104 authenticates the first subject as the second subject when the similarity is equal to or greater than a preset similarity threshold.

  The touch panel 105 is combined with a display device (display unit) such as a liquid crystal panel and a transparent plate-like position input sensor. When the user touches (touches) the display on the screen of the display device, the touch panel 105 outputs position information indicating the touch position.

  For example, the decoder 106 decodes image encoded data such as an MPEG (Moving Picture Expert Group) method held in the DRAM 101, and outputs the decoded image data to the DRAM 101. A media interface (Media I / F) 107 reads encoded image data from the recording medium 200 attached to the image reproducing apparatus 100 into the DRAM 101.

  The CPU 109 controls the entire image reproduction device 100. A ROM (Read Only Memory) 111 stores a program that operates on the CPU 109. A RAM (Random Access Memory) 112 is used as a work memory for the CPU 109.

  The motion vector detection unit 113 detects a motion vector indicating the motion of a designated area (predetermined area) designated on the screen in a plurality of pieces of image data temporarily stored in the DRAM 101. A plurality of designated areas can be designated.

  For example, the following program is stored in the ROM 111 described above, and the CPU 109 executes the next process corresponding to the program.

  When the position information obtained from the touch panel 105 matches the position of the subject area (subject position information) detected by the subject detection unit 103, the CPU 109 performs subject selection determination processing for determining that a subject has been selected.

  The CPU 109 detects the subject position (that is, the subject region) in the image data decoded by the decoder 106 using the subject detection unit 103 during normal moving image reproduction, and obtains subject locus information indicating the subject locus. A subject trajectory information generation process is performed. Further, the CPU 109 performs a trajectory drawing process for drawing a subject trajectory line indicating the trajectory of the subject in the display reproduction image data existing in the DRAM 101 according to the subject trajectory information.

  Further, the CPU 109 determines whether the coordinate information obtained by moving a finger or the like with the subject selected on the touch panel 105 is on the subject locus line drawn by the locus drawing process or in a predetermined proximity range. A trajectory coordinate determination process is performed. In addition, the CPU 109 obtains the amount of movement of the subject in accordance with the subject trajectory information in the moving image scene being reproduced, and performs subject movement determination processing for determining whether or not the position of the subject is moving.

  Further, the CPU 109 calculates a motion vector of a predetermined area (eg, background) excluding the subject, and generates movement information (screen background movement information, that is, area position information) of the entire screen based on the motion vector. Background movement information generation processing is performed. Then, the CPU 109 performs background relative trajectory information generation processing for generating background relative trajectory information indicating the relative trajectory of the subject with respect to the background of the screen according to the subject trajectory information and the screen background movement information.

  In addition, the CPU 109 determines whether the coordinate information obtained by moving a finger or the like with the subject selected on the touch panel 105 matches the background relative locus information or is within a predetermined proximity range. Judgment processing is performed.

  As shown in the figure, the image reproducing apparatus 100 is provided with a data bus 102 for accessing the DRAM 101 and a control bus 108 for the CPU 109 to give control instructions to the subject detection unit 103 to the media I / F 107. Is provided. Further, the image reproducing apparatus 100 is provided with a program bus 110 that connects the CPU 109 with the ROM 111 and the RAM 112.

  FIG. 2 is a diagram illustrating an example of a moving image scene obtained as a result of shooting while panning the camera to follow the subject.

  In FIG. 2, a subject 201 that is a car is moving in the right direction in the figure. Here, it is assumed that photographing is performed while panning the camera so that the subject 201 is always located at the center of the photographing screen. . Here, it is assumed that there are moving image scenes from Scene1 to Scene8, and the time has passed in the order of Scene1 to Scene8. That is, Scene 1 is the oldest and Scene 8 is the newest.

  In Scene 1 to Scene 8, since shooting is performed while panning the camera so that the subject 201 is positioned at the center of the shooting screen, the predetermined area (for example, the background) 202 excluding the subject 201 is also moved. It becomes a state.

  FIG. 3 is a diagram showing an example of a reproduction screen when the CPU 109 performs background relative locus drawing processing in Scene 5 of the moving image scene shown in FIG. Here, it is assumed that the encoded image data indicating the moving image scene is read from the recording medium 200 into the DRAM 101 and reproduced.

  First, the CPU 109 performs decoding processing for three frames before and after Scene 5 by the decoder 106, and then determines the movement amount of the subject 201 in Scene 2 to Scene 7 by the subject movement determination processing described above. Then, the CPU 109 determines whether or not the position of the subject has moved according to the amount of movement of the subject 201.

  Here, since the subject 201 is photographed while panning the camera so that the subject 201 is located in the center of the photographing screen, the CPU 109 determines that the position of the subject 201 has not moved.

  Next, the CPU 109 obtains movement information of the background 202 of the entire screen excluding the subject 201 by background movement information generation processing. Here, since shooting is performed by panning the camera so that the subject 201 is positioned at the center of the shooting screen, the background 202 also moves to the left in the drawing as described above.

  Subsequently, the CPU 109 draws the locus of the subjects 201 of Scene 2 to Scene 7 on the background 202 of Scene 5 that is the current reproduction display scene by the above-described background relative locus drawing processing, and the subject locus line 301 shown in FIG. Is displayed on the screen.

  In the illustrated example, the subject locus line 301 displays plot points 302 to 307 indicating the position of the subject 201 from Scene 2 to Scene 7 in Scene 5. The subject locus line 301 and the plot points 302 to 307 allow the user not only to easily grasp the movement locus of the subject 201 but also to confirm the position of the subject 201 in each scene.

  FIG. 4 is a diagram for explaining an example of moving image scene feed playback performed by the image playback apparatus shown in FIG. Here, a case will be described in which playback is performed from Scene 5 to Scene 7 during playback display on the display screen shown in FIG. 3 (ie, scene jump).

  In a state where Scene 5 is displayed on the display unit, the user selects (drags) the subject 201 on the touch panel 105 with the finger 501 or the like. Then, with the subject 201 selected, the subject 201 is moved out of the subject locus line 301. At this time, the CPU 109 displays Scene 5 on the display screen without updating the playback scene of the moving image. Then, in order to indicate that the user has selected the subject 201, the CPU 109 compositely draws the image of the selected subject 201 as a semi-transparent icon 502 on the display screen.

  Subsequently, with the subject 201 selected, the user moves the subject 201 (that is, the semi-transparent icon 502 here) to a position indicating Scene 7 on the subject locus line 301. When the translucent icon 502 moves the subject position on Scene 7 on the subject locus line 301 (that is, the plot point 307), the CPU 109 reproduces and displays Scene 7 corresponding to the position of the subject 201 on the subject locus line 301 on the screen.

  In this way, when the user selects the subject 201 on the screen shown in FIG. 3 and moves the semi-transparent icon 502 indicating the subject 201 outside the subject locus line 301, the CPU 109 reproduces and displays the moving image scene. Stop updating. That is, the CPU 109 continues to display and display the moving image scene in the current state. When the translucent icon 502 is moved to the position of the subject 201 indicating Scene 7 that is the desired scene on the subject trajectory line 301 (that is, the plot point 307), the CPU 109 corresponds to the subject corresponding to the moving position of the translucent icon 502. Screen 7 in which 201 exists is displayed on the screen.

  FIG. 5 is a flowchart for explaining the trajectory drawing process performed by the camera shown in FIG. Note that the processing according to the illustrated flowchart is performed under the control of the CPU 109. Here, it is assumed that the encoded image data indicating the moving image scene is read from the recording medium 200 into the DRAM 101 and reproduced.

  When the trajectory drawing process is started in response to a user instruction, first, the CPU 109 decodes a plurality of frames before and after the moving image scene being reproduced and displayed on the current screen by the decoder 106 and temporarily stores them in the DRAM 101. Decode. Then, the CPU 109 performs subject trajectory information generation processing for a plurality of decoded frames (that is, images) stored in the DRAM 101 to generate subject trajectory information (step S501).

  Subsequently, the CPU 109 determines whether or not the position of the subject is moving based on the subject locus information by subject movement determination processing (step S502). Here, the CPU 109 determines that the position of the subject has not moved if the movement distance of the subject is within a predetermined range.

  If it is determined that the position of the subject is moving (YES in step S502), the CPU 109 reproduces and displays the trajectory of the subject (subject trajectory line) by the trajectory drawing process using the subject trajectory information (that is, the scene). (Step S503). Then, the CPU 109 ends the locus drawing process.

  On the other hand, if it is determined that the position of the subject has not moved (NO in step S502), the CPU 109 obtains the motion vector of the entire screen (for example, a predetermined region such as the background) excluding the subject 201 by the background movement information generation process. Calculation is performed to generate screen movement information (that is, background movement information) based on the motion vector (step S504).

  Next, the CPU 109 uses the subject locus information and the background movement information to generate subject locus information for the background in the scene currently being reproduced and displayed by the background relative locus information generation processing (step S505).

  Subsequently, the CPU 105 draws a trajectory indicating the position of the subject (that is, a subject trajectory line) on the screen that is currently being reproduced and displayed based on the background relative trajectory information by a trajectory drawing process (step S506). Then, the CPU 109 ends the locus drawing process. By the processing in step S506, for example, as described with reference to FIG. 3, the subject locus line 301 indicating the subject position for each moving image scene is drawn on the screen.

  FIG. 6 is a flowchart for explaining moving image scene feed playback performed by the image playback apparatus shown in FIG. Note that the processing according to the illustrated flowchart is performed under the control of the CPU 109. Here, it is assumed that one scene in the moving image scene is displayed on the screen, and the above-described subject locus line is drawn on the screen.

  When the moving image scene playback is started, the CPU 109 determines whether or not a subject is selected (dragged) by a touch operation on the touch panel 105 in the moving image scene displayed on the screen by subject selection determination processing (step). S601). If no subject has been selected (NO in step S601), CPU 109 ends moving image scene feed reproduction. That is, the CPU 109 performs normal playback.

  On the other hand, when a subject is selected (YES in step S601), CPU 109 acquires a touch position (detected position) on touch panel 105 from touch panel 105 (step S602). Then, the CPU 109 determines whether or not the detected position on the touch panel 105 is located on the subject locus line displayed on the screen by the locus coordinate determination processing (step S603).

  When the detection position is on the subject locus line (YES in step S603), the CPU 109 decodes the moving image scene (that is, the frame) in which the subject corresponding to the position on the subject locus line exists, displays it on the screen, and reproduces it. The display image is updated (step S604).

  Subsequently, the CPU 109 draws a subject locus line corresponding to the reproduced display image on the screen according to the updated reproduced display image, and updates the subject locus line (step S605). At this time, the CPU 109 draws the subject locus line, for example, as described in FIG. Then, the CPU 109 returns to the process of step S601.

  If the detection position is not located on the subject locus line (NO in step S603), the CPU 109 temporarily stops the update of the moving image reproduction display (step S606). Then, the CPU 109 returns to the process of step S601.

  As described above, in the first embodiment of the present invention, when the subject is moved outside the subject locus line by the operation on the touch panel on the screen displaying the moving image scene, the CPU 109 temporarily stops the reproduction of the moving image. . When the subject is again positioned on the subject locus line, the CPU 109 reproduces a moving image scene corresponding to the position on the subject locus line where the subject is located. As a result, even in a moving image scene obtained as a result of shooting while panning the camera so that the subject is positioned at the center of the shooting screen, the user can easily see the movement path of the subject and reproduce it in the desired scene. Feeding can be done intuitively.

[Second Embodiment]
Next, an example of an image reproduction device according to the second embodiment of the present invention will be described. Note that the hardware configuration of the image playback apparatus according to the second embodiment is the same as that of the image playback apparatus shown in FIG.

  FIG. 7 is a diagram showing moving image scene feed playback performed by the image playback apparatus according to the second embodiment of the present invention. Here, a case will be described in which playback is performed from Scene 5 to Scene 7 during playback display on the display screen shown in FIG. 3 (ie, scene jump).

  In a state where Scene 5 is displayed on the screen, the user selects (drags) the subject 201 on the touch panel 105 with the finger 501 or the like. At this time, the CPU 109 displays Scene 5 on the display screen without updating the playback scene of the moving image. Then, in order to indicate that the user has selected the subject 201, the CPU 109 compositely draws the image of the selected subject 201 as a semi-transparent icon 502 on the display screen.

  The user is translucent to a position on the subject trajectory line 301 (that is, plot point 307) indicating a moving image scene (here, Scene 7) to be jumped with the subject 201 (that is, translucent icon 502 here) selected. The icon 502 is moved. Then, the user releases (drops) the translucent icon at a position (plot point 307) on the subject locus line 301 indicating Scene7.

  When the semi-transparent icon 502 is dropped at a position (plot point 307) on the object locus line 301 indicating Scene 7, the CPU 109 reproduces and displays Scene 7 corresponding to the dropped position on the object locus line on the screen.

  In this way, when the user selects the subject 201 and moves the translucent icon 502 indicating the subject 201 to a position indicating a desired moving image scene (for example, Scene 7) on the subject locus line 301, the CPU 109 performs a semi-transition. Scene 7 in which the subject 201 corresponding to the position to which the transparent icon 502 has moved is displayed on the screen.

  FIG. 8 is a flowchart for explaining moving image scene feed playback performed by the image playback apparatus according to the second embodiment of the present invention. Note that the processing according to the illustrated flowchart is performed under the control of the CPU 109. Here, it is assumed that one scene in the moving image scene is displayed on the screen, and the above-described subject locus line is drawn on the screen.

  When the moving image scene playback is started, the CPU 109 determines whether or not a subject is selected (dragged) by a touch operation on the touch panel 105 in the moving image scene displayed on the screen by subject selection determination processing (step). S801). If the subject has been selected (YES in step S801), that is, if the selection of the subject has not been canceled, the CPU 109 stops the reproduction update of the moving image scene (step S802). Then, the CPU 109 returns to the process of step S801.

  On the other hand, if no subject is selected (NO in step S801), that is, if the selection of the subject is canceled, CPU 109 obtains the touch position (detected position) on touch panel 105 from touch panel 105 (step S803). . Then, the CPU 109 determines whether or not the detection position on the touch panel 105 is located on the subject locus line 301 displayed on the screen by the locus coordinate determination process (step S804).

  When the detected position is located on the subject locus line 301 (YES in step S804), the CPU 109 decodes a moving image scene (that is, a frame) in which the subject corresponding to the position on the subject locus line 301 exists by the decoder 106 and displays the screen. Display and update the reproduction display image (step S805).

  Subsequently, the CPU 109 draws a subject locus line corresponding to the reproduced display image on the screen according to the updated reproduced display image, and updates the subject locus line (step S806). At this time, the CPU 109 draws the subject locus line, for example, as described in FIG. Then, the CPU 109 resumes the moving image reproduction from the moving image scene currently displayed on the screen (step S807), and ends the moving image scene feed reproduction.

  If the detected position is not on the subject locus line 301 (NO in step S804), the CPU 109 proceeds to the process in step S807, cancels the reproduction stop, and reproduces the moving image from the moving image scene currently displayed on the screen. I do.

  As described above, in the second embodiment of the present invention, when a subject is selected by an operation on the touch panel on the screen for displaying a moving image scene, the CPU 109 temporarily stops the reproduction of the moving image scene. When the subject is released at any position on the subject locus line, the CPU 109 starts playback from the moving image scene corresponding to the position where the subject is released. As a result, even in a moving image scene obtained as a result of shooting while panning the camera so that the subject is positioned at the center of the shooting screen, the user can easily see the locus of the subject and send the playback to the desired scene. Can be done intuitively.

  As is apparent from the above description, in the example shown in FIG. 1, the subject position detection unit 103, the motion vector detection unit 113, and the CPU 109 function as subject detection means, and the CPU 109 serves as movement determination means and first drawing means. , Function as second drawing means and display control means.
