Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram showing a circuit configuration of a digital camera 1 according to an embodiment of the present invention. The digital camera 1 includes an optical lens 2 disposed on the front surface of the main body, an image sensor 3 such as a CCD imaged by the optical lens 2, a TG 4 for driving the image sensor 3, and an output from the image sensor 3. A unit circuit 5 including a CDS that holds the captured image signal, a gain adjustment amplifier (AGC) that amplifies the image signal, and an A / D converter (AD) that converts the amplified image signal into a digital signal. Yes. Then, an image of the subject is formed on the image sensor 3 via the optical lens 2, and the image sensor 3 outputs a signal. The signal output from the image pickup device 3 is sampled, amplified, and digitized by the unit circuit 5, sent to the image processing circuit / CPU 6, converted into luminance within the image processing circuit / CPU 6, and the luminance Integration and histogram processing are performed.

  The optical lens 2 is held by a lens driving circuit 7 having an AF motor or the like, and the lens driving circuit 7 is driven by the control of the image processing circuit / CPU 6 to move in the optical axis direction. Adjust the focus of the subject image to be formed. Further, at the time of AE control, the image pickup device 3 is driven by the TG 4 based on a shutter pulse sent from the image processing circuit / CPU 6 and its charge accumulation time is controlled. Thereby, an electronic shutter is realized.

  The image processing circuit / CPU 6 controls each unit and has various signal processing and image processing functions. The image processing circuit / CPU 6 generates a video signal from an imaging signal converted into a digital signal through the unit circuit 5. Then, the subject image picked up by the image pickup device 3 is displayed as a through image on the liquid crystal display unit 8 including a TFT liquid crystal monitor or the like. Further, at the time of image pickup, the image pickup signal is compressed to generate a JPEG format image file, which is stored in an image storage medium 9 such as a flash memory, and at the time of reproduction, the compressed image file is expanded and displayed on the liquid crystal display unit 8. Display. The image processing circuit / CPU 6 includes a clock unit 10 that measures the current date and time, and the image storage medium 9 is detachable.

  Further, the image processing circuit / CPU 6 is connected to an operation key unit 11 including a cross cursor key, a shutter key, a menu key, a memory 12, a GPS (Global Positioning System) module 13, a map data storage unit 14, and a RAM 15. ing. The memory 12 is a program ROM in which operation programs necessary for control of each unit and various data processing by the image processing circuit / CPU 6 are recorded, and stores a program for executing processing shown in a flowchart described later.

  The GPS module 13 receives the C / A code of the L1 band from the geodetic satellite, demodulates and decodes it, and determines the latitude / longitude of the current position. The latitude / longitude information calculated by the GPS module 13 is It is taken into the image processing circuit / CPU 6. The map data storage unit 14 includes place data composed of character data indicating places such as city names and town names such as “Troy”, “Istanbul”, “Tokyo”, “Shibuya”, “Isezakicho”, and the place Are stored in correspondence with latitude / longitude range data. The RAM 15 temporarily stores various data and is used for work of the image processing circuit / CPU 6.

  Next, the operation of the digital camera 1 according to the above configuration will be described. FIG. 2 is a flowchart showing a processing procedure in the photographing mode. When the shooting mode is set, the image processing circuit / CPU 6 executes the processing shown in this flowchart in accordance with the program.

  In other words, the subject image captured by the image sensor 3 is displayed on the liquid crystal display unit 8 as a through image (step S101). Next, it is determined whether or not the shutter key has been operated (step S102). If the shutter key is operated, image data from the image sensor 3 is acquired (step S103). Further, the current date and time measured by the clock unit 10 is acquired as shooting date and time data (step S104), and the latitude and longitude determined by the GPS module 13 are acquired as shooting position data (step S105).

  Then, the image data acquired in step S103 is associated with the shooting date / time data acquired in step S104 and the shooting data including the shooting position data acquired in step S105, and stored in the image storage medium 9 (step S106).

  Subsequently, it is determined whether or not the mode has been changed from the shooting mode to another mode, and the loop of steps S101 to S107 is repeated until the mode is changed. Therefore, as shown in FIG. 3, the image storage medium 9 has a shooting date and time in the shooting data corresponding to each of a plurality of image data A, B, C... Shot when the shutter key is operated. The year, month, day, hour, and minute indicating the shooting date and time are stored, and the latitude and longitude are stored as the shooting position.

  Therefore, according to the present embodiment, it is possible to store shooting date / time and shooting position information required in a slide playback mode, which will be described later, together with image data at the time of shooting.

  FIG. 4 is a flowchart showing a processing procedure of the slide playback mode in the playback mode. The image data stored in the image storage medium 9 and the shooting data stored corresponding to the image data are read (step S201). Next, by comparing the shooting date and time included in the read shooting data with the current date and time counted by the clock unit 10, it is determined whether or not a certain time has passed from the shooting date and time. (Step S202).

  Here, the fixed time may be a relatively long period such as 5 years or 10 years, may be a relatively short period such as 3 days or 10 days, or may be several hours. In addition, the user may arbitrarily set this fixed time.

  If it is determined in step S202 that a predetermined time has elapsed, an image based on the image data read in step S201 is displayed (step S203), and the shooting date and time is displayed in a part of the image. The shooting date and time is displayed based on the data (step S204). Therefore, when an image that has passed a predetermined time or more from the shooting date and time is played back as a slide, as shown in FIG. 5 (A-1), the liquid crystal display unit 8 has a playback image 81 based on the image data and a part thereof The shooting date and time 82 is displayed.

  Therefore, when the user visually recognizes the shooting date and time 82, memories such as memories related to the reproduced image 81 can be revived, and the fun at the time of reproduction can be improved.

  On the other hand, if it is determined in step S202 that a predetermined time or more has not elapsed since the photographing date and time, only the image based on the image data is displayed (step S205). Therefore, when a relatively new image that has not passed a predetermined time from the shooting date and time is reproduced by sliding, a replay image 81 based on the image data is displayed on the liquid crystal display unit 8 as shown in FIG. Only displayed.

  Therefore, an unnecessary shooting date and time is not added to an image that is relatively new and has not been passed for a certain period of time since the shooting date and time and the user's memory is clear. The influence on the reproduced image 81 can be prevented in advance.

  Next, based on the shooting position data (latitude / longitude at the time of shooting) included in the shooting data read in step S101, a place name or the like is searched and acquired from the map data storage unit 14 (step S206). That is, as described above, the map data storage unit 14 stores character data indicating locations such as city names and town names such as “Troy”, “Istanbul”, “Tokyo”, “Shibuya”, and “Isezakicho”. Corresponding location data and latitude / longitude range data indicating the location are stored correspondingly. Therefore, the map data storage unit 14 obtains a location such as a city name or a town name corresponding to the shooting position data (latitude / longitude at the time of shooting) included in the shooting data. Based on the acquired location data (character data), a place name indicating the shooting location is displayed on a part of the image (step S207).

  Therefore, as a result of the processing in step S207, as shown in FIGS. 5A-2 and B-2, the liquid crystal display unit 8 includes a part of the reproduced image 81 based on the image data such as “Istanbul”. A shooting location 83 is displayed.

  Therefore, when the user visually recognizes the photographing place 83, memories such as memories related to the reproduced image 81 can be revived, and the fun at the time of reproduction can be improved.

  Subsequently, it is determined whether or not the shooting date and time is displayed on the liquid crystal display unit 8 (step S208). At this time, as shown in FIG. 5A-2, if the shooting date and time 82 is displayed, the determination in step S208 is YES. Accordingly, the process proceeds from step S208 to step S209, and the shooting date / time is faded out. As a result, the characters of the shooting date and time 82 shown in FIG. 5A-2 are gradually thinned, and the display state of (A-2) is shifted over time to the display state of (B-2). .

  Therefore, by erasing the shooting date and time 82 over time by fading out in this way, it is possible to enhance the effect of rendering during slide playback, and to improve interest during playback.

  Next, it is determined whether or not the reproduction of all images has been completed, or whether or not there has been a termination instruction due to a transition instruction from slide reproduction to another mode (step S210). Repeat the process. Therefore, by repeatedly executing the processing from step S201, slide reproduction is performed in which the image data stored in the image storage medium 9 is sequentially read and reproduced.

  In the present embodiment, only the shooting date / time 82 is faded out, but the shooting location 83 may be faded out. As a result, after the shooting date and time 82 and the shooting location 83 are once displayed together with the reproduced image 81, the display state of only the reproduced image 81 can be shifted.

(Second Embodiment)
FIG. 6 is a flowchart showing a processing procedure in the slide reproduction mode according to the second embodiment of the present invention. The image data stored in the image storage medium 9 and the shooting data stored corresponding to the image data are read (step S301). Next, it is determined whether or not a reproduced image is already being displayed (step S302). At this time, if the playback image has not yet been displayed on the liquid crystal display unit 8 immediately after the start of the slide playback mode, the determination in step S302 is NO.

  Accordingly, the process proceeds from step S302 to step S303, and the current time is counted from the shooting date and time by comparing the shooting date and time included in the shooting data read out in step S301 with the current date and time counted by the clock unit 10. It is determined whether or not the above has elapsed. As a result of the determination in step S303, if a predetermined time or more has elapsed, an image based on the image data read in step S301 is displayed (step S304), and the shooting date / time data is displayed in a part of the image. The shooting date and time is displayed based on (Step S305). Therefore, when an image that has passed a predetermined time or more from the shooting date and time is played back as a slide, as shown in FIG. 5 (A-1), the liquid crystal display unit 8 has a playback image 81 based on the image data and a part thereof The shooting date and time 82 is displayed.

  On the other hand, if the result of determination in step S303 is that a predetermined time or more has not elapsed since the shooting date and time, only the image based on the image data is displayed (step S306). Therefore, when a relatively new image that has not passed a predetermined time from the shooting date and time is reproduced by sliding, a replay image 81 based on the image data is displayed on the liquid crystal display unit 8 as shown in FIG. Only displayed.

  Next, based on the shooting position data (latitude / longitude at the time of shooting) included in the shooting data read in step S101, a place name or the like is searched and acquired from the map data storage unit 14 (step S307). Based on the acquired location data (character data), a place name indicating the shooting location is displayed on a part of the reproduced image (step S308). Therefore, as a result of the processing in step S307, as shown in FIGS. 5A-2 and B-2, the liquid crystal display unit 8 includes a part of the reproduced image 81 based on the image data such as “Istanbul”. A shooting location 83 is displayed.

  Next, it is determined whether or not the reproduction of all images has been completed, or whether or not there has been an instruction for termination due to, for example, an instruction to shift from slide reproduction to another mode (step S309). If there is no end instruction, the process returns to step S301, and the next image data stored in the image storage medium 9 and the shooting data stored corresponding to the next image data are read (step S301). ). Further, as described above, it is determined whether or not the reproduced image is already being displayed (step S302). At this time, since the reproduced image has already been displayed on the liquid crystal display unit 8 by the processing in step S304, the determination in step S302 is YES.

  Therefore, the process proceeds from step S302 to step S310, and image switching display is performed. That is, instead of the currently displayed reproduced image 81, an image based on the image data read in step S301 is displayed.

  Next, based on the shooting position data (latitude / longitude at the time of shooting) included in the shooting data read in step S101, a place name or the like is searched and acquired from the map data storage unit 14 (step S311). Then, depending on whether the acquired place name and the like match the place name indicating the shooting location displayed in a part of the playback image in step S308, the shooting location of the previous playback image and the current playback image is determined. It is determined whether or not there has been a change (step S312).

  As a result of the determination in step S312, the acquired place name does not match the place name indicating the shooting location displayed in a part of the reproduced image in step S308, and the previous reproduced image and the current reproduced image are not matched. If there is a change in the shooting location, the process proceeds to step S308 described above, and a place name indicating the playback shooting location acquired in step S311 is displayed on a part of the playback image (step S308). Therefore, if the shooting location of the previous playback image is “Istanbul” and the shooting location of this playback image is “Troy”, there is a change from the shooting date and time when there is a change in the shooting location. Even if the time has not passed, the shooting location “Troy” is displayed.

  Therefore, when there is a change in the shooting location in this way, even if a certain time or more has not passed since the shooting date and time, the shooting location is displayed, so that the user can view the playback image before and after the slide playback, Differences in shooting locations can be clearly understood.

  On the other hand, if the result of determination in step S312 is that there is no change in the shooting location, the shooting date and time is displayed on a part of the image based on the shooting date and time data (step S313). Therefore, when there is no change in the shooting location and images taken at the same location are reproduced continuously, only the shooting date and time are displayed.

  Therefore, the user can understand that continuously reproduced images were taken at the same place by displaying only the shooting date and time, and by visually checking the shooting date and time 82, the user can understand at the same shooting place. Memory of memories related to the playback image 81 can be revived, and the fun at the time of playback can be improved.

  In this embodiment, the shooting date / time 82 is continuously displayed without fading out, but it may be faded out as in the above-described embodiment.

(Third embodiment)
FIG. 7 is a flowchart showing a processing procedure in the slide reproduction mode according to the third embodiment of the present invention. The image data stored in the image storage medium 9 and the shooting data stored corresponding to the image data are read (step S401). Next, it is determined whether or not a reproduced image is already being displayed (step S402). At this time, if the playback image has not yet been displayed on the liquid crystal display unit 8 immediately after the start of the slide playback mode, the determination in step S402 is NO.

  Accordingly, the process proceeds from step S402 to step S408, and an image based on the image data read out in step S401 is displayed on the liquid crystal display unit 8. Further, the shooting date and time is displayed on a part of the image based on the shooting date and time data (step S409). Therefore, immediately after the start of reproduction, as shown in FIG. 8A, the shooting date and time of “2007/06/18 13:08” is included in a part of the image A-1 displayed on the liquid crystal display unit 8. 82 is displayed.

  Next, the displayed shooting date and time is stored in the RAM 15 (step S410). Accordingly, in this example, the displayed shooting date and time “2007/06/18 13:08” is stored in the RAM 15.

  Subsequently, it is determined whether or not the reproduction of all images has been completed, or whether or not there has been an instruction for termination due to an instruction to shift from slide reproduction to another mode (step S411). If there is no end instruction, the process returns to step S401, and the next image data stored in the image storage medium 9 and the shooting data stored corresponding to the next image data are read (step S401). ). Further, as described above, it is determined whether or not a reproduced image is already being displayed (step S402). At this time, since the reproduced image A-1 is displayed in the state of FIG. 8A, the determination in step S402 is YES.

  Accordingly, the process proceeds from step S402 to step S403, and it is determined whether or not the shooting date / time is also being displayed. At this time, in the state of FIG. 8A, since the shooting date 82 is displayed together with the reproduced image A-1, the determination in step S403 is YES. Accordingly, the process proceeds from step S403 to step S404, and the shooting date and time 82 is deleted. When erasing the shooting date and time 82, it may be faded out as in the above-described embodiment.

  Next, an image switching display is performed (step S405). That is, instead of the currently displayed reproduced image, an image based on the image data read in step S401 is displayed. Accordingly, as shown in FIGS. 8A to 8B, the image A-1 is switched to the image A-2.

  Further, the photographing date / time data included in the photographing data read in step S101 is acquired (step S406). Then, by comparing the shooting date / time data of the current display image acquired in step S406 with the shooting date / time data of the current display image stored in step S410, the shooting date / time of the display image of this time is displayed. It is determined whether or not a certain time has passed since the date and time (step S407).

  This fixed time can be arbitrarily set by the user, and is 5 hours in this example. Accordingly, if the image A-2 in (b) in FIG. 8 is taken within 5 hours from the shooting date and time “2007/06/18 13:08” of the image A-1 in (a), step S407 is performed. The determination is NO. Therefore, the process proceeds to step S411 without performing the processes in steps S409 and S410. Therefore, in this case, as shown in FIG. 8B, the shooting date and time are not displayed, and only the image A-2 is displayed.

  However, for example, if the shooting date / time data of the image switched and displayed in step S405 is, for example, “2007/06/19 11:05”, the shooting date / time of the current display image has passed a predetermined time or more from the already displayed shooting date / time. It will be done. Accordingly, the process proceeds from step S407 to step S409, and the shooting date / time is displayed in a part of the image based on the shooting date / time data. Therefore, as shown in FIG. 8C, the shooting date and time 82 composed of “2007/06/19 11:05” is displayed on a part of the image B-1 displayed on the liquid crystal display unit 8. It becomes. In addition, the shooting date and time “2007/06/19 11:05” is stored in the RAM 15 by the processing in step S410.

  When the process from step S401 is repeated again, the shooting date and time of the image switched and displayed in step S405 is five hours from the shooting date and time “2007/06/19 11:05” stored in the RAM 15 in step S410. If it is less, the determination in step S407 is NO. Accordingly, the processes in steps S409 and S410 are not executed, and the shooting date and time are not displayed.

  That is, as shown in FIG. 8, the shooting date / time is not additionally displayed on the image A-2 that was shot within 5 hours from the shooting date / time “2007/06/18 13:08” of the image A-1. The image date / time “2007/06/19 11:05” is displayed on the image B-1 that has been captured after five hours or more from the image date / time “2007/06/18 13:08” of the image A-1. "Is additionally displayed.

  In addition, the shooting date and time are additionally displayed on the images B-2, B-3, and B-4 that were shot within 5 hours from the shooting date and time “2007/06/19 11:05” of the image B-1. First, the image date / time “2007/06/20 14: The image date / time“ 2007/06/19 11:05 ”of the image B-1 is taken for the image C-1 that has been imaged for more than 5 hours. 08 "is additionally displayed.

  In addition, the images C-2 and C-3, which are images taken within 5 hours from the image date and time “2007/06/20 14:08” of the image C-1, are not additionally displayed. The image date / time “2007/06/20 20:48” is added to the image D-1 that has been imaged five hours or more after the image date / time “2007/06/20 14:08”. Is displayed.

  In addition, the images D-2 and D-3, which are images taken within 5 hours from the image date / time “2007/06/20 20:48” of the image D-1, are not additionally displayed. The image date / time “2007/06/21 09:34” is added to the image E-1 that has been imaged five hours or more after the image date / time “2007/06/20 20:48”. Is displayed. The images E-2, D-3, D-4, and D-5, which were taken within 5 hours from the shooting date and time “2007/06/21 09:34” of the image E-1, are displayed on the shooting date and time. Only the image is displayed without additional display.

  Therefore, according to the present embodiment, a long period of time has elapsed from the shooting date and time while preventing unnecessary inconvenience that an unnecessary shooting date and time is additionally displayed on an image shot at a time close to each other. Thereafter, in an appreciation mode in which the captured image is reproduced and viewed, it is possible to revive the memories related to the reproduced image based on the displayed shooting date and time.

(Fourth embodiment)
FIG. 9 is a flowchart showing a processing procedure in the slide playback mode in the fourth embodiment of the present invention. The image data stored in the image storage medium 9 and the photographing data stored corresponding to the image data are read (step S501). Next, it is determined whether or not a reproduced image is already being displayed (step S502). At this time, if the playback image has not yet been displayed on the liquid crystal display unit 8 immediately after the start of the slide playback mode, the determination in step S502 is NO.

  Accordingly, the process proceeds from step S502 to step S508, and an image based on the image data read out in step S501 is displayed on the liquid crystal display unit 8. Further, based on the shooting position data (latitude / longitude at the time of shooting) included in the shooting data read in step S501, a place name or the like is retrieved from the map data storage unit 14 and acquired (step S509). Then, based on the acquired location data (character data), a place name indicating the shooting location is displayed on a part of the reproduced image, and the shooting date / time is displayed based on the shooting date / time data included in the shooting data. (Step S510). Accordingly, immediately after the start of reproduction, as shown in FIG. 10A, a part of the image A-1 displayed on the liquid crystal display unit 8 includes a shooting location 83 made of “Troy” and “2007/06”. / 18 13:08 ”is displayed.

  Next, the displayed shooting location is stored in the RAM 15 (step S511). Therefore, in this example, the displayed shooting location “Troy” is stored in the RAM 15.

  Subsequently, it is determined whether or not the reproduction of all the images has been completed, or whether or not there has been a termination instruction due to an instruction to shift from slide reproduction to another mode (step S512). If there is no end instruction, the process returns to step S501, and the next image data stored in the image storage medium 9 and the photographing data stored corresponding to the next image data are read (step S501). ). Further, as described above, it is determined whether or not a reproduced image is already being displayed (step S502). At this time, since the reproduced image A-1 is displayed in the state of FIG. 10A, the determination in step S502 is YES.

  Accordingly, the process proceeds from step S502 to step S503, and it is determined whether or not the shooting location is being displayed. At this time, in the state of FIG. 10A, since the shooting location 83 and the shooting date and time 82 are displayed together with the reproduced image A-1, the determination in step S503 is YES. Accordingly, the process proceeds from step S503 to step S504, and the shooting location 83 and the shooting date and time 82 are deleted. At the time of erasing, it may be faded out in the same manner as in the above-described embodiment.

  Next, an image switching display is performed (step S505). That is, an image based on the image data read in step S501 is displayed instead of the currently displayed reproduced image. As a result, as shown in FIGS. 10A to 10B, the image A-1 is switched to the image A-2.

  Further, based on the shooting position data (latitude / longitude at the time of shooting) included in the shooting data read in step S101, a place name or the like is searched and acquired from the map data storage unit 14 (step S506). Then, by comparing the shooting location of the current display image acquired in step S506 with the shooting location already displayed stored in step S511, it is determined whether or not the shooting location has changed (step S507). .

  Therefore, if the image A-2 in FIG. 10B is taken at the same location as the location “Troy” of the image A-1 in FIG. The determination in S507 is NO. Therefore, the process proceeds to step S512 without performing the processes in steps S510 and S511. Therefore, in this case, as shown in FIG. 10B, the shooting location and the shooting date and time are not displayed, and only the image A-2 is displayed.

  However, for example, if the shooting location data of the image switched and displayed in step S505 is “Rome”, for example, the shooting location of the current display image is the location already displayed. Therefore, the process proceeds from step S507 to step S510, and the shooting location and the shooting date and time including the place name acquired in step S506 are displayed on a part of the image. Accordingly, as shown in FIG. 10C, the shooting location 83 and the shooting date and time 82 made up of “Rome” are displayed in a part of the image B- 1 displayed on the liquid crystal display unit 8. Further, the shooting location “Rome” is stored in the RAM 15 by the processing in step S511.

  When the processing from step S501 is repeated again, if the shooting location of the image switched and displayed in step S505 is the shooting location “Rome” stored in the RAM 15 in step S511, the determination in step S507 is NO. It becomes. Therefore, the processing of step S510 and step S511 is not executed, and the shooting location and the shooting date / time are not displayed.

  That is, as shown in FIG. 10, the image A-2, which is an image taken at the same location as the image location “Troy” of the image A-1, is not additionally displayed, and the image A-1 is taken. The image location “Rome” is additionally displayed on the image B-1 that is imaged at a location different from the location “Troy”.

  In addition, in the images B-2, B-3, and B-4 that are taken at the same place as the shooting location “Rome” of the image B-1, no shooting location is additionally displayed. The image location “Athens” is additionally displayed on the image C-1 that is imaged at a location different from the image location “Rome”.

  In addition, the images C-2 and C-3, which are images taken at the same location as the image location “Athens” of the image C-1, are not additionally displayed, and the image location “Athens” of the image C-1 is not displayed. The image location “Venice” is additionally displayed on the image D-1 captured at a location different from “”.

  In addition, the images D-2 and D-3, which are images taken at the same location as the image location “Venice” of the image D-1, are not additionally displayed, and the image location “Venice” of the image D-1 is displayed. The image location “Istanbul” is additionally displayed on the image E-1 captured at a location different from “”. Then, the images E-2, D-3, D-4, and D-5, which are images taken at the same location as the image location “Istanbul” of the image E-1, are displayed without any additional display of the image location. Only displayed.

  Therefore, according to the present embodiment, after a long period of time has elapsed from the shooting date and time, while preventing unnecessary inconvenience that an unnecessary shooting location or the like is additionally displayed on the image shot at the same location and hindering image viewing, In an ornamental form in which a photographed image is reproduced and viewed, memories such as memories related to the reproduced image can be revived based on the displayed photographing location.

  In this embodiment, the shooting date and time are displayed together with the shooting location. However, only the shooting location may be displayed.

In the present embodiment, when the previous shooting location and the current shooting location are images taken at the same location, the shooting location is not additionally displayed, and on the other hand, they are shot at different locations. In the case of the captured image, the name of the shooting location or the like is additionally displayed. In the process of FIG. 9, the processes of FIGS. 407 and S407 are added, for example, as shown in FIG. In addition to displaying the name of the shooting location, etc., the shooting date and time may be displayed together.
