  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  In the present embodiment, a digital camera will be described as an example of an image playback device. The image playback device is not limited to a digital camera, and may have a function of storing a plurality of images including still images and moving images, and a function of reproducing them, for example, a digital still camera, a video camera, and a mobile phone. A music player, a computer, or the like.

  FIG. 1 is a block diagram showing an example of a schematic configuration of a digital camera according to an embodiment of the present invention. Referring to FIG. 1, a digital camera 1 includes a CPU 11 that controls the entire digital camera 1, a lens group 13 including a plurality of lenses including a focus lens 13F and a zoom lens 13Z, a shutter 14, and a lens group. 13 and a lens driving unit 15 for driving the shutter 14, a camera shake correction unit 17, an image sensor 19, a codec (CODEC) 21, a signal processing circuit 22 for image processing, a liquid crystal display (LCD) 23, and a CPU 11 EEPROM (Electrically Erasable and Programmable Read Only Memory) 25 that stores programs to be executed by the CPU, and SDRAM (Synchronous Dynamic Random) used as a work area of the CPU 11 m Access Memory) 27, a card interface (I / F) 29 in which a memory card 29A is mounted, a gyro sensor 33, an operation unit 35 that accepts a user's operation, and the entire digital camera 1 are supplied with power. A battery 41.

  The lens group 13 is provided on the front surface of the digital camera 1 main body, and the LCD 23 is provided on the back surface of the digital camera 1 opposite to the surface on which the lens group 13 is provided. The lens group 13 is controlled by the lens driving unit 15. The lens driving unit 15 is controlled by the CPU 11 to move the focus lens 13 </ b> F of the lens group 13 and adjust the diaphragm of a diaphragm mechanism (not shown) provided in the lens group 13. The lens group 13 includes a zoom lens 13Z provided for changing and adjusting the zoom magnification.

  The image sensor 19 is a photoelectric conversion element such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor, and its imaging plane is perpendicular to the optical axis of the lens group 13. The image sensor 19 photoelectrically converts an optical image of a subject formed on the imaging surface via the lens group 13 and outputs image data to the CPU 11. The CPU 11 receives image data output from the image sensor 19 and stores the image data in the SDRAM 27. The image data here is, for example, bitmap format data in which one pixel is composed of R (red), G (green), and B (blue). The image sensor 19 is not limited to a CMOS image sensor, and a CCD (Charge Coupled Device) image sensor may be used. In this embodiment, the output from the image sensor 19 is converted into digital image data by an analog / digital converter (not shown).

  The shutter 14 is provided between the lens group 13 and the image sensor 19 and is controlled by the lens driving unit 15 when taking a still image. The lens driving unit 15 adjusts the shutter speed by controlling opening and closing of the shutter 14. When the user half-presses the shutter button 35A included in the operation unit 35 or when the user presses a button for starting moving image shooting, the lens driving unit 15 opens the shutter 14 and performs a predetermined time interval. To output one frame of image data. A frame is a unit constituting a moving image, and one frame means one image. The frame can be replaced with a field. The predetermined time interval is, for example, 1/30 second when the frame rate is 30 FPS.

  The CPU 11 moves the focus lens 13F of the lens group 13 to the lens driving unit 15 and moves the image output from the image sensor 19 in response to the user pressing the shutter button 35A of the operation unit 35 halfway. Based on the data, an autofocus process for focusing the lens group 13 is executed and the exposure is determined. The exposure includes a shutter speed that determines a time for opening the shutter 14 and an aperture amount of an aperture mechanism provided in the lens group 13.

  In the present embodiment, an example of executing autofocus processing for focusing the lens group 13 based on image data output from the image sensor 19 is shown. However, the distance to the subject using infrared rays or the like is shown. May be measured to determine the position of the focus lens 13F. In the present embodiment, the exposure is determined based on the image data output from the image sensor 19. However, in order to measure the amount of light transmitted through the lens group 13, the exposure is determined separately. A sensor may be provided, and the exposure may be determined from the amount of light measured by another sensor.

  The image sensor 19 is controlled by the CPU 11 to control the time for photoelectric conversion. Specifically, the CPU 11 causes the lens drive unit 15 to open the shutter 14 when the image sensor 19 starts photoelectric conversion. Thereby, since the light transmitted through the lens forms an image on the image sensor 19, the image sensor 19 starts photoelectric conversion. When the exposure time determined by the shutter speed has elapsed, the CPU 11 causes the lens driving unit 15 to close the shutter 14 and causes the image sensor 19 to output image data. Note that the image data output from the image sensor 19 can be displayed on the LCD 23 as a through image by opening the shutter 14 using the electronic shutter function of the image sensor 19. When the electronic shutter function provided in the image sensor 19 is used, the shutter 14 is closed only from the end of the exposure time for obtaining image data to be stored later until the image sensor 19 completes the output of the image data. Can do.

  The signal processing circuit 22 reads the image data stored in the SDRAM 27, performs various signal processing on the image data, and converts the image data into a color system YUV format represented by a luminance signal and a color difference signal. The signal processing circuit 22 stores YUV format image data in the SDRAM 27.

  The CPU 11 generates an RGB signal from the YUV format image data stored in the SDRAM 27 and outputs the RGB signal to the LCD 23. As a result, an image output by the image sensor 19 by photographing the subject is displayed on the LCD 23. Instead of the LCD 23, an organic EL (ElectroLuminescence) display may be used.

  The codec 21 is controlled by the CPU 11 and reads out YUV format image data stored in the SDRAM 27 and compresses and encodes the image data. Here, the codec 21 compresses and encodes image data by the MPEG method or the JPEG method.

  The CPU 11 stores the image data compressed and encoded by the codec 21 in the memory card 29A. The memory card 29A can divide the storage area into a plurality of folders, and the CPU 11 stores image data in a predetermined storage area among the plurality of storage areas of the memory card 29A.

  The gyro sensor 33 detects an angular velocity when the main body of the digital camera 1 rotates. Here, assuming that the horizontal direction is the X axis, the vertical direction is the Y axis, and the optical axis of the lens is the Z axis, the gyro sensor 33 is centered on the angular velocity in the rotational direction (yaw direction) centered on the Y axis and the X axis. Are detected, and the angular velocities in the yaw direction and the pitch direction are output to the CPU 11. The CPU 11 calculates the movement amount of the main body in the X-axis direction from the angular velocity in the yaw direction, and calculates the movement amount of the main body in the Y-axis direction from the angular velocity in the pitch direction.

  The camera shake correction unit 17 moves the image sensor 19 to minimize blurring of the optical image formed on the imaging surface of the image sensor 19. For this reason, the camera shake correction unit 17 includes driving units corresponding to the two directions in order to move the image sensor 19 in two directions that are parallel to the image forming plane of the image sensor 19 and intersect each other. Here, the two directions are a horizontal direction (X-axis direction) and a vertical direction (Y-axis direction) that intersect at right angles to each other. The imaging surface of the image sensor 19 is a surface perpendicular to the optical axis of the lens group 13. Since the image sensor 19 moves in two directions that are parallel to the image forming surface of the image sensor 19 and intersect each other by the camera shake correction unit 17, even if the camera shakes, the same subject can be photographed without shaking during exposure.

  The card I / F 29 is loaded with a memory card 29A having a nonvolatile memory. The CPU 11 can access the memory card 29A via the card I / F 29, and stores the encoded data stored in the SDRAM 27 in the memory card 29A.

  FIG. 2 is a functional block diagram illustrating an example of functions of the control unit in the present embodiment. The functions shown in FIG. 2 are realized in the CPU 11 when the CPU 11 executes an image reproduction program stored in the EEPROM 25. In place of the CPU 11, the function shown in FIG. 2 may be realized by a circuit.

  Although an example in which the image reproduction program is stored in the EEPROM 25 is shown here, the image reproduction program stored in the memory card 29A may be loaded into the SDRAM 27 and executed. The storage medium for storing the image reproduction program is not limited to the memory card 29A, but a flexible disk, cassette tape, optical disk (CD-ROM / MO / MD / DVD), IC card, optical card, mask ROM, EPROM, A semiconductor memory such as an EEPROM may be used. When a communication circuit for connecting to a network or the like is provided, an image reproduction program is downloaded from another computer connected to the network via the communication circuit, and the program is stored in the EEPROM 25.

  The shooting mode setting unit 61 sets a shooting mode input by the user to the operation unit 35. The shooting mode setting unit 61 displays a setting screen for setting a shooting mode on the LCD 23 and accepts an operation for setting a shooting mode input by the user to the operation unit 35. The shooting mode is a condition for executing processing from the shooting control unit 63 shooting a subject and outputting image data. The shooting modes include a still image shooting mode for shooting still images and a moving image shooting mode for shooting moving images. Furthermore, in the still image shooting mode, the shooting mode includes a single shooting mode for shooting one still image in response to a single shooting instruction from the user, and a plurality of continuous shooting modes in response to a single shooting instruction from the user. A continuous shooting mode for shooting a still image, and includes a backlight shooting mode for correcting when shooting a movie with backlight in the movie shooting mode, and an indoor shooting mode for correcting when shooting a movie in the room. The shooting mode setting unit 61 outputs the set shooting mode to the shooting control unit 63 and the storage control unit 69.

  Note that the shooting mode is not limited to these. For example, the exposure or shutter speed is determined as long as it defines an operation for executing a series of processes for storing image data after shooting a subject. It may be a mode or the like.

  The shooting control unit 63 receives the shooting mode from the shooting mode setting unit 61, controls the lens driving unit 15, the image sensor 19, and the camera shake correction unit 17 according to the shooting mode, and outputs image data output from the image sensor 19 to The data is output to the storage controller 69. The image data output by the shooting control unit 63 includes still image data and moving image data. Hereinafter, the term “image data” includes still image data and moving image data.

And including. The shooting condition detection unit 65 calculates an AF evaluation value, and detects a shooting condition indicating whether or not the subject is in focus based on the AF evaluation value. The AF evaluation value is a value indicating the sharpness of the image data, for example, a value of a high frequency component of the image data. For example, the difference between the pixel values of adjacent pixels can be used as the AF evaluation value. The AF evaluation value may be calculated by processing the image data using a filter for calculating the sharpness. Further, the sharpness may be calculated for each of a plurality of regions in the image data, and a value obtained by weighted averaging the calculated plurality of sharpnesses may be used as the AF evaluation value. The imaging condition detection unit 65 determines that the subject is in focus when the AF evaluation value is an extreme value equal to or greater than the threshold value, and the AF evaluation value does not become an extreme value equal to or greater than the threshold value. When it is determined that the subject is not in focus. The shooting condition detection unit 65 detects whether or not the subject is in focus based on the calculated AF evaluation value, and stores the shooting condition indicating whether or not the subject is focused. Output to the control unit 69.

  In addition, the shooting condition detection unit 65 calculates an AE evaluation value, and detects a shooting condition indicating whether or not the brightness is normal based on the AE evaluation value. The AE evaluation value is a scale indicating the brightness of the image data. For example, a value obtained by weighted averaging the luminance values of a plurality of regions in the image data can be used as the AE evaluation value. When the AE evaluation value is equal to or lower than the upper threshold TB1 and the lower threshold TB2, the shooting condition detection unit 65 determines that an image with normal brightness is being shot, and the AE evaluation value exceeds the upper limit. If the threshold value TB1 or less and the lower threshold value TB2 or more are not exceeded, it is determined that an image with normal brightness has not been captured. The imaging condition detection unit 65 detects whether or not an image with normal brightness is captured based on the calculated AE evaluation value, and indicates whether or not an image with normal brightness is captured. The condition is output to the storage control unit 69.

  Furthermore, the imaging condition detection unit 65 determines whether or not the camera shake amount output from the camera shake correction unit 17 exceeds a range that can be corrected by the camera shake correction unit 17, and if the camera shake amount exceeds the correctable range. It is determined that camera shake has occurred, and if the camera shake amount is within the camera shake correction range, it is determined that camera shake has not occurred. The shooting condition detection unit 65 outputs shooting conditions indicating whether or not the camera shakes to the storage control unit 69.

  The storage condition setting unit 67 sets storage conditions that the user inputs to the operation unit 35. The storage condition setting unit 67 displays a storage condition setting screen for setting storage conditions on the LCD 23, and accepts an operation for setting storage conditions input by the user to the operation unit 35. The storage conditions are conditions for storing the image data in the memory card 29A, and are, for example, the number of pixels that determines the size of the stored image data, a compression encoding method for compressing the image data, a compression rate, and the like. The storage condition setting unit 67 outputs the set storage condition to the storage control unit 69.

  The storage control unit 69 includes a still image storage unit 71, a moving image storage unit 73, and a feature addition unit 75. The still image storage unit 71 is activated when the still image shooting mode is set by the shooting mode setting unit 61, and still image data input from the shooting control unit 63 is input from the storage condition setting unit 67. Compression is performed according to the storage conditions, and the compressed still image data is stored in the memory card 29A. Further, the still image storage unit 71 generates a reduced image obtained by reducing the still image, and stores the generated image data of the reduced image in association with the image data of the still image. The reduced image is an image having a predetermined size. The still image storage unit 71 stores the shooting mode input from the shooting mode setting unit 61 and the shooting conditions input from the shooting condition detection unit 65 in association with still image data.

  The moving image storage unit 73 is activated when the moving image shooting mode is set by the shooting mode setting unit 61, and the moving image data input from the shooting control unit 63 is set as a storage condition input from the storage condition setting unit 67. Therefore, the compressed image data of the moving image is stored in the memory card 29A. The moving image storage unit 73 selects a still image of a moving image input from the shooting control unit 63 as a representative image, generates a reduced representative image by reducing the representative image, and generates image data of the generated reduced representative image. It is stored in association with moving image data. The representative reduced image is a still image having the same size as the reduced image of the still image. The moving image storage unit 73 stores the shooting mode input from the shooting mode setting unit 61 and the shooting condition input from the shooting condition detection unit 65 in further association with the image data of the moving image.

Further, the feature of the image includes information on whether or not the subject is a red eye when the subject is a person. The feature of the image includes the number of persons who are subjects when the subject is a person. The feature adding unit 75 stores image features in association with still image data stored in the still image storage unit 71 or moving image data stored in the moving image storage unit 73.

  The image display control unit 51 selects one of a plurality of types of image data stored in the memory card 29A, and displays image data associated with the selected image data. Specifically, when the selected image data is a still image, the image data of the reduced image associated with the image data is displayed, and when the selected image data is a moving image, the representative associated with the image data is displayed. Display the image data of the reduced image. The display image control unit 51 includes an image data selection unit 53 that selects one of a plurality of types of image data stored in the memory card 29A, and a type determination unit 55 that determines the type of image of the selected image data. And a pattern determining unit 57 that determines one of a plurality of patterns whose display modes change, and a switching display unit 59.

  When the user inputs a browsing instruction to the operation unit 35, the image data selection unit 53 sequentially selects one of the plurality of image data stored in the memory card 29A. The image data selection unit 53 selects image data in the order stored in the memory card 29A. The image data initially selected by the image data selection unit 53 varies depending on the state of the digital camera 1. When a browsing instruction is input immediately after shooting a still image or a moving image, the image data stored last in the memory card 29A is selected first. When a browsing instruction is input immediately after the digital camera 1 is turned on, the image data stored first in the memory card 29A is first selected. The image data selection unit 53 outputs the identification information of the selected image data to the type determination unit 55. Here, the identification information of the image data is used as the file name.

  The type determination unit 55 determines the type of image data of the identification information input from the image data selection unit 53 and outputs the determined type to the pattern determination unit 57. The type includes a moving image and a still image.

  The pattern determination unit 57 receives a type from the type determination unit 55 and determines a pattern predetermined for the type from among a plurality of patterns prepared in advance. The pattern determining unit 57 outputs the pattern name of the determined pattern to the switching display unit 59. The pattern defines a method of changing the display mode of an image displayed with the passage of time in a period immediately before display before image data is completely displayed. The display mode includes the position, shape, size, brightness, and color for displaying an image. Here, a pattern with the pattern name “slide-in” is assigned to the image type “still image”. The pattern with the pattern name “slide in” is a method of changing the position of displaying an image in the display mode. Specifically, the reduced image is moved from the upper side to the lower side from outside the displayable range. When the display mode of the reduced image changes in this pattern, the portion of the reduced image that enters the displayable range gradually spreads upward from the lower side of the reduced image, so that the reduced image appears to slide from the upper side.

  Also, a pattern with the pattern name “zoom” is assigned to the image type “moving image”. The pattern with the pattern name “zoom” is a method of changing the size of the image in the display mode. Specifically, the representative reduced image is gradually enlarged and displayed from the state where the reduced image of the representative reduced image is arranged and displayed at the center of the displayable range. Thus, a method of gradually increasing the size of the representative reduced image to be displayed is assigned. When the display mode is changed in this pattern, the representative reduced image is gradually displayed larger, so that it appears to zoom in.

  When the image data selected by the image data selection unit 53 is a still image, the switching display unit 59 inputs the reduced image data associated with the image data of the still image from the pattern name “ In accordance with the “slide in” pattern, the display mode is changed and displayed on the LCD 23 during the immediately preceding display time. The user can know that the selected image data is a still image by the change of the display mode until the reduced image is completely displayed by the switching display unit 59. When the image data selected by the image data selection unit 53 is a moving image, the switching display unit 59 displays the image data of the representative reduced image associated with the moving image data as the pattern name “zoom” input from the pattern determination unit 57. The display mode is changed and displayed on the LCD 23 during the immediately preceding display time according to the pattern "." The change of the display mode until the representative reduced image is completely displayed by the switching display unit 59 allows the user to know that the selected image data is a moving image. The immediately preceding display time is a time before displaying image data of a still image and before displaying image data of a representative reduced image of a moving image, and is a predetermined time.

  Further, the switching display unit 59 displays the reduced image data on the LCD 23 when the image data is a still image, and the representative reduced image image data on the LCD 23 when the image data is a moving image. The reduced image is an image obtained by reducing a still image, and the representative reduced image is an image obtained by reducing one frame of a moving image. Therefore, the data amount is small. For this reason, the processing speed can be shortened compared with the case of displaying one frame of a still image or a moving image. For this reason, the last display time can be shortened as much as possible.

Here, assuming that the image data of the representative reduced image 313 associated with the image data of the moving image is displayed while the image 301 is displayed, the display is switched from the image 301 to the representative reduced image 313. Shows changes. In the display mode of the pattern with the pattern name “zoom”, an image 313A obtained by reducing the representative reduced image 313 is superimposed and displayed on the central portion of the image 301, and then the image 313A is gradually enlarged and displayed on the image 301. The ratio of the overlapping parts increases with the passage of time. FIG. 4A is a diagram illustrating a state before image switching. With reference to FIG. 4A, an image 301 before the representative reduced image 313 is displayed is displayed. FIG. 4B is a diagram showing a state during switching. Referring to FIG. 4B, an image 313A obtained by reducing the representative reduced image 313 is superimposed and displayed at the center of the image 301. FIG. 4C shows a state after image switching. Referring to FIG. 4C, representative reduced image 313 is displayed on the entire screen, and image 301 is not displayed.

  FIG. 5 is a flowchart illustrating an example of the flow of image reproduction processing. The image reproduction process is a process executed by the CPU 11 when the CPU 11 executes an image reproduction program stored in the EEPROM 25 or the memory card 29A. Referring to FIG. 5, CPU 11 determines whether or not a browsing instruction has been accepted. When the user inputs a browsing instruction to the operation unit 35, the browsing instruction is received from the operation unit 35. The process waits until a browsing instruction is accepted (NO in step S01). If a browsing instruction is accepted (TES in step S01), the process proceeds to step S02.

  In step S02, the first image data to be processed is selected. One of a plurality of still image and moving image data stored in the memory card 29A is selected. When a browsing instruction is input immediately after shooting a still image or a moving image, immediately after the image data of the still image or moving image stored in the memory card 29A is selected and the digital camera 1 is turned on. When a browsing instruction is input, the image data of the still image or moving image stored first in the memory card 29A is selected.

  In the next step S03, related image data is read out. Image data associated with the image data selected for processing is read out. The image data of the reduced image is associated with the image data of the still image, and the image data of the representative reduced image is associated with the image data of the related image of the moving image.

  Then, the type of the image data selected as the processing target is determined (step S04). Here, the image type is a file type, and it is determined whether it is a moving image or a still image. In the next step S05, a pattern is determined. A predetermined pattern corresponding to the type of image determined in step S04 is determined. Here, if the image type is determined to be a still image in step S03, the pattern name “slide-in” is determined. If the image type is determined to be a moving image in step S03, the pattern name “zoom” is determined. ] Pattern.

  In the next step S06, the related image data read in step S03 is displayed on the LCD 23 according to the pattern determined in step S05. If the image data selected for processing is a still image, the reduced image is displayed with the pattern name “slide-in”. If the selected image data is a movie, the representative reduced image has the pattern name “zoom”. Displayed as a pattern. For this reason, it is possible to know the type of image data selected from the change in the display mode in which the reduced image or the representative reduced image is displayed, here, the distinction between a still image and a moving image. In addition, since the image data of the reduced image or the representative reduced image is displayed instead of displaying the selected image data itself, the time for displaying the image while reducing the amount of data to be processed for display. Can be shortened.

  In step S07, the process is branched depending on the file type of the image data selected as the processing target. If the file type is a still image, the process proceeds to step S08. If the file type is a moving image, the process proceeds to step S09. In step S08, the image data of the still image selected as the processing target is displayed instead of the image data of the reduced image, and the process proceeds to step S14. After the display in which the display mode of the reduced image data is changed according to the pattern ends, the still image data itself is displayed. Thereby, the user can browse an image with better image quality.

  On the other hand, in step S09, after the display of changing the display mode of the image data of the representative reduced image according to the pattern of the pattern name “zoom” is completed, the image data of the representative reduced image is displayed. Then, it is determined whether or not a reproduction instruction has been accepted (step S10). When the user designates a reproduction button provided in the operation unit 35, the reproduction instruction is accepted. If a reproduction instruction is accepted, the process proceeds to step S11. If not, the process proceeds to step S14.

  In step S11, the moving image of the image data selected as the processing target is reproduced. Thereby, the reproduced moving image is displayed instead of the representative reduced image. Then, it is determined whether or not the reproduction is finished. When the reproduction of the moving image is completed or when an instruction of a stop button provided in the operation unit 35 by the user is detected, it is determined that the reproduction is completed. If reproduction has ended, the process proceeds to step S13; otherwise, the process returns to step S11. In step S13, the reproduction of the moving image ends, and the process proceeds to step S14.

  In step S14, it is determined whether a sending instruction has been accepted. If the user indicates a feed button provided in the operation unit 35, a feed instruction is received from the operation unit 35. If a sending instruction is accepted, the process proceeds to step S15; otherwise, the process proceeds to step S16. In step S15, the next image data is selected, and the process returns to step S03. Here, the image data that has not been selected as a processing target among the plurality of image data stored in the memory card 29A and that has been stored in the memory card 29A is selected first. If a plurality of image data stored in the memory card 29A can be selected in order, it may be selected in a different order, for example, in order from the later stored image data.

  On the other hand, in step S16, it is determined whether or not a browsing end instruction has been accepted. If the user indicates a browse end button provided in the operation unit 35, a browse end instruction is received from the operation unit 35. If a browsing end instruction is accepted, the process ends. If not, the process returns to step S14.

<First Modification>
The digital camera 1 in the above-described embodiment has been described by taking the case where the image type of the image data is a still image and a moving image as an example, but the image type is a combination of the file type and the shooting mode.
