Abstract

PROBLEM TO BE SOLVED: To improve working efficiency and convenience when a desired photographic image is searched from among a plurality of photographic images.SOLUTION: A DSP/CPU 5 sets a current position acquired by a GPS block 8 as position data for search and sets a current direction (direction to which a camera body is directed) acquired by a direction sensor 16 as direction data for search. A predetermined angular range of the current direction is determined as a search target using the current position as a center, and, from among a plurality of pieces of image data recorded in a memory card 15, all the pieces of image data where a photographic position added as attribute information is included in the range of the search target is extracted as a display candidate. The extracted image data is switched in an order according to the distance from the current position to the photographic position in accordance with an operation of a zoom key in a key input part 7. Since the search target is changed in accordance with a change of the current position or the current direction, a new display candidate can be narrowed down only by moving and rotating the camera body.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an outline of an electrical configuration of a digital camera according to the present invention. As shown in the figure, the digital camera according to the present embodiment forms an image through the lens group that includes a lens group constituting a focus lens and a zoom lens, and a drive circuit for driving the lens group, and the lens group. A CCD 2 for converting an optical image of the subject to an imaging signal.

  The CCD 2 is driven by a drive signal generated by a TG (Timing Generator) 3 to pick up an image of the subject and outputs the image pickup signal to the analog signal processing circuit 4. The analog signal processing circuit 4 includes a CDS that holds an input imaging signal, a gain adjustment amplifier (AGC) that amplifies the imaging signal, and an A / D converter (AD) that converts the amplified imaging signal into a digital imaging signal. The imaging signal after digital conversion is sent from the analog signal processing circuit 4 to the DSP / CPU 5.

  The DSP / CPU 5 is a one-chip microcomputer that has various digital signal processing functions including image data compression / decompression and audio data processing, and controls each part of the digital camera. The DSP / CPU 5 is provided with a built-in clock having a calendar function.

  A display device 6, a key input unit 7, a GPS block 8, and a sensor block 10 are connected to the DSP / CPU 5, and a DRAM 12, a built-in flash memory 13, and a card interface 14 are connected via an address / data bus 11. Yes. The card interface 14 is connected to a memory card 15 that is detachably attached to a card slot of a camera body (not shown).

  The DRAM 12 is a buffer that temporarily stores image data of a subject that has been digitized after being imaged by the CCD 2, and is also used as a working memory of the DSP / CPU 5. The image data temporarily stored in the DRAM 12 is sent to the display device 6 through various image processes by the DSP / CPU 5 when in the recording standby state in the recording mode. Further, after being compressed (encoded) by the DSP / CPU 5 at the time of shooting, finally, the model name of the camera, the shooting date and time, the shooting position (latitude and longitude), the compressed image data (image data body), It is recorded on the memory card 15 as a still image file having a predetermined format such as an Exif format to which various attribute information such as shooting conditions is added.

  The display device 6 includes a color LCD and its drive circuit, and displays the subject image captured by the CCD 2 as a through image in the shooting standby state, and is read out from the memory card 15 and expanded by the DSP / CPU 5 in the playback mode. It is a display means of the present invention for displaying an arbitrary recorded image. The key input unit 7 includes a plurality of operation keys such as a power key, a mode key used for setting a basic operation mode of a recording mode and a playback mode, a shutter key, a zoom key, a MENU key, a cross key, and a set key. A key input signal corresponding to the key operation by the user is output to the DSP / CPU 5.

  The GPS block 8 is indispensable for determining the latitude / longitude of the control circuit that demodulates and decodes the L1 band C / A code (GPS data) from the satellite received by the GPS antenna 9 and calculates the latitude / longitude of the current position. It consists of a memory that stores data related to the geodetic system, and a clock circuit that counts the local time with high accuracy in order to determine the reception timing of radio waves sent from GPS satellites. Send to DSP / CPU5. The latitude and longitude data acquired here is recorded in the still image file as position information indicating the shooting location.

  The sensor block 10 includes an azimuth sensor 16 and an acceleration sensor 17, an amplifier that amplifies the output signals of the sensors 16 and 17, and an A / D converter that converts the amplified output signal into a digital detection signal. Detection signals from the sensors 16 and 17 are output to the DSP / CPU 5. The azimuth sensor 16 is a sensor for detecting in which direction the camera body is directed with reference to the optical axis of the lens group of the optical system block 1, and the acceleration sensor 17 is the front, rear, left, right of the camera body. This is a sensor for detecting the amount of movement in the direction. In this embodiment, the sensor block 10 functions as the detection means of the present invention.

  The built-in flash memory 13 is a memory in which an image storage area for storing a file of an image taken in a state where the memory card 15 is not attached to the camera body and a program area are secured. In the program area, various control programs and data necessary for controlling the digital camera by the DSP / CPU 5 are stored. The above control program causes the DSP / CPU 5 to execute the program necessary for AE (automatic exposure) control and AF (automatic focus adjustment) control and the processing described later, thereby allowing the DSP / CPU 5 to perform the search means, display control means, and search of the present invention. To function as condition change means (first search condition change means, second search condition change means), first detection means, second detection means, third detection means, selection means, and selection condition change means Image display program. Further, setting data relating to various functions of the digital camera set by the user is stored in the program area.

  Next, the processing contents of the DSP / CPU 5 when the image viewing mode provided as a lower mode of the reproduction mode is set in advance in the digital camera of the present embodiment will be described. The image browsing mode is an operation mode that is provided assuming that a desired image is searched for from among captured images recorded on the memory card 15. In the following description, it is assumed that only the still image data (still image file) is recorded on the memory card 15, but the image viewing mode is not limited to a still image, but a desired moving image (recorded by another digital camera). It is also used when searching for (

  2 and 3 are flowcharts showing the processing contents of the DSP / CPU 5 in the image browsing mode. As shown in FIG. 2, when the image browsing mode is set, the DSP / CPU 5 first acquires the current position (latitude and longitude of the current location) by the GPS block 8 and the current direction (camera body is (Direction directed) is acquired (step S1), and the acquired current position and current direction are set as search position data and initial values of the search direction data, and stored in the DRAM 12 (step S2). ).

  Next, after the position indicated by the search position data (current position at the beginning of the process) is set as the search target within the 10 ° left and right angle range of the direction indicated by the search direction data (step S3). ), From among a plurality of image data (still image files) recorded in the memory card 15, all image data in which the shooting position added as attribute information is included in the search target range are displayed as display candidates. (Step S4).

  For example, when the shooting positions of the plurality of image data recorded on the memory card 15 are P1 to P9 as shown in FIG. 4, the current position of the camera body is the position A and the current direction (camera When the orientation of the main body is true east, image data with the shooting positions P4 to P6 are extracted as display candidates, the current position of the camera body is the position B, and the current direction (the orientation of the camera body) is true north. If it is, image data of the shooting positions P2, P5, and P8 are extracted as display candidates.

  Subsequently, in the extracted image data, a search is made for a display that is not displayed in the past predetermined time and the shooting position is closest to the position indicated by the search position data, and the distance is set as display distance data. Store in the DRAM 12 (step S5). Further, for each of the image data extracted in step S4, the distance from the position indicated by the search position data to the photographing position is calculated, and the image data whose distance is closest to the distance indicated by the display distance data is displayed. After selection as a target (step S6), the selected image data is displayed on the display device 6 (step S7).

  Further, after the image data is displayed, when the user performs a zoom key operation (hereinafter referred to as a zoom operation) (YES in step S8), the value of the display distance data at that time (in accordance with the zoom operation) ( The distance is changed so as to increase if the operation is to the telephoto side, and to decrease if the operation is to the wide-angle side, and the display distance data is updated (step S9). The ratio of the change amount of the display distance data to one operation of the zoom key is a predetermined ratio.

  Thereafter, the process returns to the above-described step S6, and among the already extracted image data, the distance from the position indicated by the search position data to the photographing position is the largest as the distance indicated by the updated display distance data. After the near image data is selected as a new display target, the selected image data is displayed on the display device 6 (step S7). This process is skipped when the image data selected in step S6 is already being displayed. After this, if there is further operation of the zoom key, the above processing is repeated.

  Therefore, by repeating the operation of the zoom key, all the image data extracted (searched) as display candidates at that time are sorted in the order (ascending order or descending order) according to the distance from the current position at each photographing position. It can be displayed on the display device 6.

  On the other hand, as long as the zoom key is not operated (NO in step S8), the DSP / CPU 5 moves the camera body in the front / rear / left / right direction based on the detection signal of the acceleration sensor 17 as shown in FIG. Whether or not there has been a (parallel translation) operation is sequentially confirmed. If there is such a movement operation (YES in step S10), the search position data is updated in response to the movement amount of the camera body in response (step S11). . Further, based on the detection signal of the azimuth sensor 17, it is confirmed whether or not there has been a rotation operation that changes the orientation of the camera body by the user, that is, a horizontal rotation operation centered on the Z axis (vertical axis) of the camera body. If there is such a rotation operation (YES in step S12), the azimuth data for search is updated in response to the rotation amount of the camera body in response (step S13).

  Although not shown, in the present embodiment, the search position data is updated only when the amount of movement of the camera body exceeds a predetermined amount, and the search direction data is updated. This is performed only when the amount of rotation exceeds a predetermined amount.

  When the position data for search or the direction data for search changes as the camera body is moved or rotated (YES in step S14), the process returns to step S3 in FIG. 2 to update the search target. In other words, if the search position data has changed, the position indicated by the new search position data is used as a center, and a new angle within the 10 ° angle range in the direction indicated by the previous search direction data. If the search direction data is set as a search target and the search direction data has changed, the position indicated by the search position data up to that point is 10 ° to the left and right of the direction indicated by the new search direction data. The angle range is set as a new search target.

  Subsequently, from among a plurality of image data (still image files) recorded on the memory card 15, all image data in which the shooting position added as attribute information is included in the new search target range are set as display candidates. After a new extraction (step S4), the processes of steps S5 to S9 described above are repeated. That is, a plurality of image data of new display candidates are displayed on the display device 6 in an order (ascending order or descending order) according to the distance from the current position in response to the operation of the zoom key.

  Until the user is instructed to end browsing by a predetermined key operation (NO in step S15), the processing after step S3 and the processing after step S8 are repeated as necessary. If the end of browsing is instructed at this point (YES in step S15), all processing in the image browsing mode is ended.

  As described above, in the image browsing mode, a certain number of image data is narrowed down as display candidates based on the shooting positions added as attribute information to each image data, and the narrowed display candidates are based on the shooting positions. They can be displayed individually according to the display order. At that time, the display candidate image data switching operation, that is, a new display candidate narrowing operation based on the shooting position, is performed only by moving and rotating (mainly rotating) the camera body without performing complicated key operations. Can be done by. Therefore, the workability and work efficiency when searching for a desired image from the still images recorded on the memory card 15 can be improved as compared with the conventional case.

  Further, in the present embodiment, the update of the search position data in step S11 is limited to the case where the movement amount of the camera body exceeds a predetermined amount, and the search direction data in step S13 is updated. The update is performed only when the rotation amount of the camera body exceeds a predetermined amount. Therefore, for example, while the user is confirming while switching an image group of a certain display candidate by operating the zoom key, it is possible to prevent the display candidate from being changed due to an unintended movement of the camera body.

  Here, in the present embodiment, the camera body movement amount and rotation amount required for updating (changing) the search position data and search direction data has been described, but the movement amount and rotation are fixed. A configuration in which the amount can be set in advance by the user or a configuration in which the amount is set automatically may be adopted. As a method for the automatic setting, for example, immediately after obtaining the search position data and the search direction data for the first time, the shooting positions of all the image data recorded on the memory card 15 are confirmed. At the same time, a map showing the shooting positions of all image data centered on the current position indicated by the search position data is created, and based on the map, it is determined by the direction indicated by the search direction data at each time point. A method of increasing or decreasing the amount of movement or rotation based on the amount of movement or rotation according to the number of image data in the angle range that includes the angle range to be searched and is wider than that angle range can be considered.

  The same applies to the above-described angle range of the search target (in this embodiment, the angle range of 10 ° to the left and right of the direction indicated by the search azimuth data). Also, it may be configured so that the user can set it in advance or automatically set it. As a method for automatic setting, for example, a method of increasing or decreasing the reference angle range based on the above-described map so as not to increase the number of image data to be extracted can be considered.

  The same applies to the change amount of the display distance data for one operation of the zoom key, and the fixed amount has been described. However, the change amount (the change ratio of the display distance data to the operation of the zoom key) is as follows. The user may be able to set in advance or may be set automatically. As a method for the automatic setting, for example, the minimum distance and the maximum distance among the distances from the position indicated by the search position data to the shooting position of each image data extracted in step S4 are described. A method of increasing or decreasing the reference change amount according to the difference is conceivable.

  Further, in the present embodiment, the description has been given of the case where both the attribute information used as the search condition when extracting (searching) the display candidate and the attribute information used as the selection condition when selecting the display target both use the shooting position. The attribute information used as the search condition and the selection condition in the present invention is not limited to the above-described attribute information, and arbitrary attribute information can be used. That is, for the search condition, if the attribute information is effective for image data extraction (search), for example, the shooting date and time, the photographer, the type of shooting mode prepared according to the shooting scene of the digital camera (night view mode, The values of items such as sports mode, person mode, etc. can be used. As for the selection condition, if it is effective for specifying the display order, for example, a value of an item such as a shooting date and time can be used.

  Furthermore, it is good also as a structure which a user can select the attribute information (specific item of attribute information) used as a search condition and a selection condition. In that case, for example, in a setting mode for setting various functions of the digital camera, a setting screen that displays attribute information that can be used as a search condition and a selection condition is displayed, and desired attribute information is displayed on the setting screen. Are selected and stored in the program area of the built-in flash memory 13 as setting information relating to the image browsing mode. In the image browsing mode, the selected attribute information may be used as a search condition or a selection condition.

  In the present embodiment, the movement of the camera body serving as a trigger for changing the value of the attribute information (specific item) that is the search condition is described as movement in the front / rear / left / right direction, and rotation in the horizontal direction. In the present invention, the type of movement of the camera body serving as the trigger is not limited to this, and any other type of movement can be used as a trigger as long as it is a detectable type of movement. The camera body may be rotated about the axis of either the axis or the z axis.

  Furthermore, it is good also as a structure which a user can select the kind of motion of the camera main body used as the trigger which changes the value of the attribute information (specific item) which is search conditions. Even in that case, as in the case of the attribute information used as the search condition and the selection condition described above, in the setting mode, the type of the desired movement is selected and stored as setting information regarding the image browsing mode, In the image browsing mode, processing that uses the movement of the selected type of camera body as a trigger may be performed.

  In the present embodiment, the trigger for changing the value of the attribute information (specific item) that is the selection condition has been described as the operation of the zoom key. It can also be the movement of the camera body. In this case, any type of motion can be used as long as the motion of the camera body can also be detected. Even in this case, it is possible to adopt a configuration in which the user can select the same as the type of movement of the camera body that is a trigger for changing the value of the attribute information (specific item) as the search condition. Furthermore, even in that case, the user may be allowed to set the ratio of the amount of change in the value of the attribute information corresponding to the amount of movement of the camera body in advance, or may be set automatically.

  In the present embodiment, the case where the present invention is applied to a digital camera has been described. However, the present invention is not limited to a digital camera, and has a function of recording captured images and displaying those captured images. For example, the present invention can be applied to, for example, a mobile phone terminal with a camera with a built-in digital camera or various portable information devices that do not have a camera function.
