Further, the above-described reader unit 25 is provided at the lower part of the camera body 41.

  Next, the electrical configuration of the digital camera will be described with reference to the block diagram of FIG. The CPU 70 as control means controls each part of the digital camera 10 based on operation signals input from the operation unit 50 and the shutter button 60. The ROM 71 stores a control program executed by the CPU 70, various control data, and the like. The flash memory 72 as information storage means is a non-volatile memory capable of rewriting data, and stores various setting information set by the photographer and shooting location information read from the IC cards 12 and 30 described above. .

  The photographing lens 43 is driven by a lens driving mechanism 75 including a motor. The lens driving mechanism 75 moves the photographing lens 43 forward and backward in the optical axis direction. The motor driver 76 controls the lens driving mechanism 75 based on a command from the CPU 70 to change the optical photographing magnification and adjust the focus. Behind the photographic lens 43, a CCD image sensor 77 as an image pickup means is arranged.

  The CCD image sensor 77 is connected to the CPU 70 via a CCD driver 78. The CPU 70 controls the CCD driver 78 to drive the CCD image sensor 77, converts the subject image into an electrical signal by photoelectric conversion, and outputs the imaging signal to the correlated double sampling circuit (CDS) 79.

  The CDS 79 removes noise of the imaging signal that is an analog signal, and the imaging signal is further amplified by the AMP 80. Thereafter, the image pickup signal is converted from an analog signal to a digital signal by the A / D converter 81 and output to the image input controller 82 as image data.

  The image input controller 82 is connected to the CPU 70 via the data bus 83. The CPU 70 controls the image input controller 82 to store the image data in the video memory 84 or the buffer memory 85.

  The video memory 84 temporarily stores image data with low resolution when the LCD panel 46 is used as an electronic viewfinder. The image data stored in the video memory 84 is transmitted to the LCD driver 86 via the data bus 83. The LCD driver 86 performs signal processing on the image data so that the image can be displayed on the LCD panel 46 and causes the LCD panel 46 to display the image.

  The buffer memory 85 temporarily stores captured high-resolution image data. In addition, an image signal processing unit 87 is connected to the CPU 70 via a data bus 83. The image signal processing unit 87 performs various types of image processing such as gradation conversion, color conversion, hypertone processing, and hyper sharpness processing while the captured high-resolution image data is stored in the buffer memory 85. Apply.

  Further, a compression / decompression processing unit 88 and a media controller 89 serving as a read / write control unit are connected to the CPU 70 via a data bus 83. The CPU 70 controls the compression / decompression processing unit 88 to perform compression processing on the image data recorded in the buffer memory 85 in a compression format such as the JPEG method. Thereafter, the CPU 70 controls the media controller 89 to record the compressed image data on the memory card 63 that is a recording medium. When the shooting location information is stored in the flash memory 72, the CPU 70 controls the media controller 89 to add the shooting location information and shooting date / time information to the compressed image data and store it in the memory card 63. Let me record. When shooting location information is not added to the flash memory 72, only shooting date / time information is added to the image data and recorded in the memory card 63.

  When reproducing the image data recorded on the memory card 63, the CPU 70 controls the media controller 89 to read the image data from the memory card 63, and further controls the compression / decompression circuit to compress the compressed image data. Perform decompression processing. The CPU 70 controls the LCD driver 86 and displays the image data on the LCD panel 46 to reproduce the recorded image. At this time, if the normal playback mode is selected by the INFO button, an image is displayed on the LCD panel 46 on a large screen. When the information display / playback mode is selected, the image is reduced and displayed together with the shooting location information stored in the flash memory 72.

  Further, the CPU 70 is connected to the AF detection unit 90 and the AE / AWB detection unit 91 via the data bus 83. The CPU 70 controls the AF detection unit 90 and the AE / AWB detection unit 91 to detect an AF detection value and an AE / AWB detection value at which automatic focus adjustment, automatic exposure adjustment, and white balance correction are optimal. The CPU 70 controls the motor driver 76, the CCD image sensor 77, and the like based on the AF detection value and the AE / AWB detection value.

  Further, the reader unit 25 and the clock unit 92 are connected to the CPU 70. The CPU 70 stores the shooting location information in the flash memory 72 when the shooting location information is read by the reader unit 25. Further, when the date / time information is read by the reader unit 25, the CPU 70 does not store the date / time information in the flash memory 72, but extracts the date / time information instantaneously when the shooting location information is read by the reader unit 25. The date information of the clock unit 92 is updated. Thereby, the time of the clock unit 92 can be adjusted.

  Next, the operation of the imaging system having the above configuration will be described. The case where the IC card 30 is used will be described. First, the reading process of the shooting location information will be described. When photographing location information is read by the digital camera 14 in a sightseeing spot, the mode is switched to the information reception mode by sliding the mode changeover switch 51. Thereafter, the photographing location information is read from the wireless tag 31 by bringing the reader unit 25 of the digital camera 14 closer to the IC card 30. The CPU 70 stores the shooting location information acquired by the reader unit 25 in the flash memory. However, the CPU 70 does not store the date / time information in the flash memory 72, but extracts the date / time information instantaneously and uses it for the time adjustment of the clock unit 92 when the photographing location information is read by the reader unit 25. Although the case where the shooting location information is read from the IC card 30 has been described, the same applies to the case where the shooting location information is read from the IC card 12.

  The shooting location information added to the image data can be selected by setting on the digital camera 14 side. The photographer operates the menu button 55 or the like to display a shooting location information selection screen 95 as shown in FIG. 8, and from among date / time information, weather information, temperature information, humidity information, position information, and location information, Information to be added to the image data can be selected. The photographer selects the information to be added by moving the cursor 96 to display “YES” and pressing the menu button 55 which is a decision button. Such shooting location information setting is stored in the flash memory 72, and only necessary shooting location information can be stored in the flash memory 72 when the shooting location information is received.

  Next, photographing processing will be described using the flowchart of FIG. When the shutter button 60 is fully pressed and a shooting command is acquired, the CPU 70 controls each part of the CCD image sensor 77 and the like to acquire image data. Thereafter, the CPU 70 determines whether or not shooting location information is stored in the flash memory 72.

  When it is determined that the shooting location information is not stored in the flash memory 72, the CPU 70 controls the media controller 89 without adding the shooting location information to the image data compressed by the JPEG method, etc. Data is recorded on the memory card 63. At this time, based on the date and time information of the clock unit 92, only the shooting date and time information is added to the image data and recorded in the memory card 63. If it is determined that the shooting location information is stored in the flash memory 72, a selection screen for allowing the photographer to select whether or not to add the shooting location information of the image data is displayed on the LCD panel 46. The photographer operates the operation unit 50 to select whether or not to add shooting location information. When the photographer selects not to add the shooting location information, the CPU 70 controls the media controller 89 to erase the shooting location information in the flash memory 72, without adding the shooting location information to the image data. It is recorded on the memory card 63. Also in this case, only the shooting date / time information is added to the image data and recorded in the memory card 63 based on the date / time information of the clock unit 92.

  If the photographer selects to add the shooting location information, the CPU 70 controls the media controller 89 to add the shooting location information in the flash memory 72 to the image data compressed by the JPEG method or the like. To be recorded in the memory card 63. At this time, based on the date / time information of the clock unit 92, information on the shooting date / time is also added to the image data and recorded in the memory card 63.

  When the shooting location information read from the IC card 12 is added to the image data, as shown in FIG. 10, the shooting date and time information and the shooting location information, which is fixed information such as the location, name, and description of the sightseeing spot, are displayed. The image file added to the data is recorded on the memory card 63. Note that the shooting date and time information need not be added to the image data. When the shooting location information read from the IC card 30 is added to the image data, as shown in FIG. 11, the shooting location information which is the above-mentioned fixed information and weather information (weather information, temperature information, humidity information) together with the shooting date and time. Is recorded on the memory card 63. Also in this case, it is not necessary to add the shooting date / time information to the image data.

  After that, when the mode switch 51 is used to switch from the shooting mode to another mode, or when the power is turned off, the shooting process is terminated. In the state where the power is turned on and the shooting mode is maintained by the mode switch, the process returns to the first process and the shooting process is repeated again.

  In the explanation of the photographing process, the photographer explained that the photographer selects whether to add the photographing location information to the image data. However, the present invention is not limited to this, and after the photographing location information is read. The shooting location information may be added to the image data and recorded in the memory card 63 only during the first shooting.

  Thus, the photographer can record a large amount of information as shooting location information in the image data by a simple operation without performing a troublesome operation. Further, since expensive parts such as GPS are not used, the manufacturing cost of an IC card or a digital camera that is an information transmitting device does not increase.

  Next, the reproduction process will be described using the flowchart of FIG. When the playback mode is selected by the mode switch 51, the digital camera 14 is in a playback mode in which image data recorded on the recording medium is displayed on the LCD panel 46. When the mode is switched to the playback mode by the mode switch 51, the CPU 70 checks the setting information in the flash memory 72 and determines whether or not the normal playback mode is set. When it is determined that the normal playback mode is set, the playback image 97 is displayed on the large screen on the LCD panel 46 as shown in FIG.

  If it is determined that the normal playback mode is not set, that is, the information display playback mode is set, the playback image 97 is reduced and displayed. Thereafter, the CPU 70 determines whether or not shooting location information is added to the image file. When it is determined that the shooting location information is added, the shooting location information added to the image data is displayed to the right of the playback image 97 together with the playback image 97 as shown in FIG. If it is determined that the shooting location information is not added, only the reproduced image 97 is displayed. At this time, information that can be understood even if the shooting location information is not added, for example, information on the shooting date and time may be displayed as shown in FIG.

  Thereafter, when the power is turned off or the mode is switched from the playback mode to another mode by the mode switch 51, the playback process is terminated. Further, when the power is kept on and the reproduction mode is maintained, the reproduction process is repeated by returning to the first process.

  In the above description of the reproduction process, the case where an image is reproduced on the LCD panel 46 of the digital camera 14 has been described. However, the present invention is not limited to this, and the image file in the memory card 63 is read into an external device such as a personal computer. The image data and the shooting location information may be displayed on the display of the personal computer by software.

  As described above, when the image data recorded in the memory card 63 is reproduced and displayed, the shooting location information can be displayed, so that the images can be easily confirmed and organized. In addition to fixed information such as the location and name of a tourist spot, weather information is also recorded as shooting location information, so that the situation at the time of shooting can be known in more detail.
