<First Embodiment>
[Schematic configuration]
FIG. 1 is a functional block diagram of a digital camera 200a according to a preferred first embodiment of the present invention. In the figure, a central processing unit (CPU) 112 includes various buttons such as a shutter button 102 and a mode switching lever 106, a cross key, a menu / execution button, a cancel / return button, a display button, a shift button, and a display switching button. Based on the input from the operation unit 157 including an enlarged display button and an AE fixed button for inputting an AE lock instruction, the respective circuits in the digital camera 200a are comprehensively controlled.

  The camera 200a includes an environmental information sensor 151a, a GPS device 159, and a gyro sensor 158. The environmental information sensor 151a is a sensor that detects information (hereinafter referred to as environmental information) that can be physically measured from the environment around the camera 200a. For example, the environmental information sensor 151a includes a temperature sensor, a humidity sensor, an atmospheric pressure sensor, an illuminance sensor, a radiation sensor, a magnetic field sensor, an atmospheric pressure sensor, a wind speed sensor, a rainfall sensor, a wind direction sensor, or a combination of some or all of them. , Temperature, humidity, atmospheric pressure, illuminance, radiation intensity, magnetic field intensity, wind speed, rainfall, wind direction, or a combination of some or all of these are detected as environmental information. The environment information sensor 151a is not limited to the above configuration as long as it can detect physically measurable information from the surrounding environment. The environmental information sensor 151a may include other sensors that detect physically measurable information. For example, a vibration sensor that detects vibration of the camera 200a, an acceleration sensor that detects movement acceleration of the camera 200a, a potentiometer that detects pressing of the shutter button 102, and the like may be included. The environmental information is recorded together with the photographed image. The timer 153 is a device that outputs the current date and time.

  A GPS (Global Positioning System) device 159 receives radio waves simultaneously transmitted from a plurality of GPS satellites orbiting over the earth by a built-in antenna. Then, the current position information is obtained by obtaining the time difference until the radio wave transmitted from each satellite reaches the GPS device 159. The gyro sensor 158 is a sensor that can detect angle information such as an angle, an angular velocity, or an angular acceleration. For example, the angular velocity sensor can be constituted by a piezoelectric vibration gyro sensor using a regular triangular prism vibrator and a piezoelectric ceramic.

  The camera 200a includes a communication unit 156 that is wired or wirelessly connected to a network such as the Internet and transmits and receives various data such as images and programs. The CPU 112 of the camera 200a transmits distribution information, which is various information distributed via a network, such as news information, exchange information, stock price information, sports information, political information, economic information, sports information, entertainment information, and weather information, to a communication unit. An acquisition unit 112b that acquires from a predetermined network resource via 156 is provided. The acquisition unit 112b receives input of designation information, which is information for designating distribution information to be acquired, such as a genre of distribution information to be acquired and a distribution date and time of the distribution information to be acquired from the operation unit 157, and conforms to the input specification information. Only the distribution information to be acquired may be acquired. This designation information is a keyword or a genre for searching for distribution information.

  The camera 200a includes an audio controller 152, a speaker 154, and a microphone 155. The audio controller 152 converts the audio data into an analog audio signal such as a 2-channel stereo signal, and outputs the analog audio signal to the speaker 154. The speaker 154 outputs audio according to this signal. The audio controller 152 may perform processing for removing high frequency components that cause noise from the analog audio signal and processing for amplifying the analog audio signal. The audio controller 152 may correspond to monaural audio other than 2-channel stereo.

  The microphone 155 is provided at a position (such as in the vicinity of the viewfinder) where the sound produced by the photographer can be collected satisfactorily, and inputs a voice memo associated with the image. The sound controller 152 converts the sound input from the microphone 155 into digital sound data, and outputs it to the memory 128 as a sound file. Alternatively, the voice controller 152 also has a function of recognizing the utterance content from the voice input to the microphone 155, converting it into a character data file (text file), and outputting it. Whether the voice controller 152 outputs a voice file or character data can be designated by selecting either “voice file output mode” or “text file output mode” from the operation unit 157. A unique file name is assigned to the sound file or text file output from the sound controller 152. Hereinafter, these file names are referred to as voice IDs. Note that the voice memo is input in advance before the shutter button 102 is half-pressed.

  Now, when the shooting mode is set by the mode switching lever 106, the CPU 112 displays a moving image (through image) on the image display device 110 so that the shooting angle of view can be confirmed. That is, the subject light that has passed through the diaphragm 116 and the photographing lens 118 forms an image on the light receiving surface of the image sensor (CCD) 120. The CCD 120 converts the subject light imaged on the light receiving surface into a signal charge in an amount corresponding to the light amount. The signal charge accumulated in this way is sequentially read out as a voltage signal (image signal) corresponding to the signal charge based on a drive pulse supplied from the timing generator 121 in accordance with a command from the CPU 112.

  The signal output from the CCD 120 is sent to an analog processing unit (CDS / AMP) 122, where the R, G, B signals for each pixel are sampled and held (correlated double sampling processing), amplified, and then A / Applied to the D converter 124. The dot sequential R, G, B signals converted into digital signals by the A / D converter 124 are stored in a memory (SDRAM) 128 via the image input controller 126. The memory 128 is used as a temporary storage area for image data, as well as a program development area and a calculation work area for the CPU 112.

  The image signal processing circuit 130 processes the R, G, and B signals stored in the memory 128 according to a command from the CPU 112. That is, the image signal processing circuit 130 includes a synchronization circuit (a processing circuit that converts a color signal into a simultaneous expression by interpolating a spatial shift of the color signal associated with the color filter array of the single CCD), a white balance correction circuit, It functions as an image processing means including a gamma correction circuit, a contour correction circuit, a luminance / color difference signal generation circuit, etc., and performs predetermined signal processing using the memory 128 in accordance with commands from the CPU 112.

  The R, G, and B signals input to the image signal processing circuit 130 are converted into luminance signals (Y signals) and color difference signals (Cr, Cb signals) and subjected to predetermined processing such as gamma correction. The YC signal processed by the image signal processing circuit 130 is stored in the VRAM 132.

  When the captured image is output to the image display device 110 as a monitor, the YC signal is read from the VRAM 132 and sent to the video encoder 134. The video encoder 134 converts the input YC signal into a predetermined display signal (for example, an NTSC color composite video signal) and outputs the converted signal to the image display device 110.

  The YC signal of each frame processed at a predetermined frame rate is alternately written in the A area and B area of the VRAM 132, and the Y area other than the area where the YC signal is written out of the A area and B area of the VRAM 132. The YC signal that has been written is read out from this area. In this way, the YC signal in the VRAM 132 is periodically rewritten, and a video signal generated from the YC signal is supplied to the image display device 110, so that the image being captured is displayed on the image display device 110 in real time. Is done. The user can check the shooting angle of view from the video (through) displayed on the image display device 110.

  Here, when the shutter button 102 is half-pressed, AE and AF processes are started. That is, the image signal output from the CCD 120 is input to the AF detection circuit 136 and the AE / AWB detection circuit 138 via the image input controller 126 after A / D conversion.

  The AE / AWB detection circuit 138 includes a circuit that divides one screen into a plurality of areas (for example, 16 × 16) and integrates RGB signals for each divided area, and provides the integrated value to the CPU 112. The CPU 112 detects the brightness of the subject (subject brightness) based on the integrated value obtained from the AE / AWB detection circuit 138, and calculates an exposure value (shooting EV value) suitable for shooting. The aperture value and shutter speed are determined according to the obtained exposure value and a predetermined program diagram, and the CPU 112 controls the electronic shutter of the CCD 120 via the timing generator 121 and controls the aperture 116 via the motor driver 140 according to this. To obtain an appropriate exposure amount.

  In addition, the AE / AWB detection circuit 138 calculates an average integrated value for each color of the RGB signals for each divided area during automatic white balance adjustment, and provides the calculation result to the CPU 112. The CPU 112 obtains an integrated value of R, an integrated value of B, and an integrated value of G, obtains a ratio of R / G and B / G for each divided area, and calculates R / G and R / G of the values of B / G. The light source type is determined based on the distribution in the color space of G, B / G, etc., and, for example, the value of each ratio is about 1 (that is, RGB in one screen) according to the white balance adjustment value suitable for the determined light source type. The gain value (white balance correction value) for the R, G, B signal of the white balance adjustment circuit is controlled so that the integration ratio of R: G: B≈1: 1: 1) Apply correction.

  Further, for example, contrast AF for moving the photographing lens 118 so that the high-frequency component of the G signal of the image signal is maximized is applied to the AF control. That is, the AF detection circuit 136 is a high-pass filter that passes only the high-frequency component of the G signal, an absolute value processing unit, and an AF that cuts out a signal within a focus target area that is preset in the screen (for example, the center of the screen). An area extraction unit and an integration unit that integrates absolute value data in the AF area are configured.

  The integrated value data obtained by the AF detection circuit 136 is notified to the CPU 112. The CPU 112 calculates a focus evaluation value (AF evaluation value) at a plurality of AF detection points while moving the photographing lens 118 by controlling the motor driver 142, and determines a lens position where the evaluation value is a maximum as a focus position. To do. Then, the motor driver 142 is controlled so as to move the photographing lens 118 to the obtained in-focus position. The calculation of the AF evaluation value is not limited to a mode using the G signal, and a luminance signal (Y signal) may be used.

  The AE / AF processing is performed, and the recording operation is started when the shutter button 102 is fully pressed. The image data acquired in response to S2 ON is converted into a luminance / color difference signal (Y / C signal) in the image signal processing circuit 130, subjected to predetermined processing such as gamma correction, and then stored in the memory 128. The

  The Y / C signal stored in the memory 128 is compressed according to a predetermined format by the compression / decompression processing circuit 144 and then recorded as an Exif (Exchangeable Image File Format) file on the storage medium 40 via the media controller 146. The image is recorded in the data part of the Exif file. The camera 200 is provided with a panoramic switch 103, which can perform shooting while switching between the normal shooting mode and the panoramic shooting mode while the shutter button 102 is fully pressed. When the shutter button 102 is fully pressed when the panorama shooting mode is on, the predetermined portions at the top and bottom of the full-size shooting screen are shielded from light and the panorama size is recorded.

  On the other hand, the environmental information sensor 151 a outputs environmental information to the CPU 112 in conjunction with the half-pressing operation of the shutter button 102. The timer 153 outputs the current date and time to the CPU 112 as shooting date and time information in conjunction with the half-pressing operation of the shutter button 102. Similarly, the GPS device 159 and the gyro sensor 158 also output current position information and angle information to the CPU 112 in conjunction with the half-pressing operation of the shutter button 102, respectively. Environment information, shooting date / time information, current position information, and angle information may be output to the CPU 112 in conjunction with the full-pressing operation of the shutter button 102. The acquisition unit 112b acquires distribution information via the network according to the designation information that has been input, and outputs the distribution information to the CPU 112.

  In conjunction with the release of the full-press operation of the shutter button 102, the CPU 112 adds environment information, shooting date / time information, distribution information, current position information, angle information, audio ID to a predetermined tag (Imagedescription tag, etc.) in the header portion of the Exif file. Record. FIG. 2 conceptually shows the contents recorded in the Exif file. A thumbnail image obtained by reducing the image at a predetermined reduction ratio is also recorded in the header portion of the Exif file. The Exif file corresponds to the image and environment information, distribution information, angle information, shooting date / time information, and audio ID. Information recorded in association with an image in the header portion of the Exif file is represented as image supplementary information. The image supplementary information includes, but is not limited to, environment information, distribution information, angle information, shooting date / time information or audio ID and a combination of some or all of them. Further, only the identification information (sound ID etc.) of the image supplementary information may be recorded in the header portion of the Exif file. In this way, even if the data size of the image supplementary information is large, the image and the image supplementary information can be associated with each other.

  When the reproduction mode is selected by the mode switching lever 106, the compressed data of the last image file (last recorded file) recorded on the storage medium 40 is read. When the file related to the last recording is a still image file, the read image compressed data is decompressed into an uncompressed YC signal via the compression / decompression processing circuit 144 and stored in the VRAM 132. The YC signal stored in the VRAM 132 is added to the video encoder 134. The video encoder 134 creates an NTSC color composite video signal from the input YC signal and outputs it to the image display device 110. Accordingly, the last frame image recorded in the storage medium 40 is displayed on the image display device 110.

  Thereafter, when a forward frame advance switch (not shown) is pressed, the frame is advanced in the forward direction, and when a reverse frame advance switch (not shown) is pressed, the frame is advanced in the reverse direction. Then, the frame-positioned image file at the frame position is read from the storage medium 40, and the frame image is reproduced on the image display device 110 in the same manner as described above. If the last frame image is displayed and the frame is advanced in the forward direction, the first frame image file recorded in the storage medium 40 is read, and the first frame image is an image. It is reproduced on the display device 110.

  The image of the Exif file need not be limited to the image obtained from the image sensor 120, and may be one received from the communication unit 156, or one recorded by a scanner, file reading / recording device, or other image recording device (not shown). . The camera 200a may be built in a mobile phone as a built-in camera of a so-called camera-equipped mobile phone.

[Process flow]
The flow of image search processing executed by the camera 200a will be described below with reference to the flowchart of FIG. In the image search process, an image search is performed based on the image supplementary information recorded in the Exif file.

  In S <b> 1, input of image supplementary information serving as an image search condition is received from the operation unit 157. In S <b> 2, the search unit 112 a of the CPU 112 searches for an Exif file based on the image supplementary information input from the operation unit 157. That is, the search unit 112a compares the image supplementary information input from the operation unit 157 with the image supplementary information recorded in a predetermined tag of the Exif file stored in the storage medium 40, and the input image supplementary information. Specify the Exif file that records the image supplementary information that matches.

  In S <b> 3, the CPU 112 displays the image recorded in the data portion of the searched (specified) Exif file on the image display device 110. In FIG. 4, the image recorded in the Exif file in which the environmental information matching the environmental information “temperature 20 ° C., humidity 50%, illuminance 2,000 lux” input as image supplementary information from the operation unit 157 is displayed. An example is shown. As shown in this figure, both the image I1 and the environment information I2 recorded in the Exif file may be displayed on the image display device 110. Of course, other image supplementary information (such as shooting date / time information) recorded in the specified Exif file may be displayed, and if the photographer refers to this image supplementary information, the situation at the time of shooting can be easily recalled. .

  With the above processing, it is possible to search for an image based on the image supplementary information recorded in the Exif file corresponding to the image, easily find a desired image, and to easily organize and classify the image. . In particular, by searching for an image based on environmental information, it becomes easy to organize and classify natural phenomena for images taken of natural phenomena.

  In addition, since the environment information, the distribution information, and the audio ID are recorded in the Exif file, when viewing the image at a later date, referring to the audio content corresponding to the environment information, the distribution information, and the audio ID, The photographer can easily recall the situation at the time of shooting, and memorable image recording becomes possible. Also, if the images and environmental information recorded at each shooting location are associated with weather information (temperature, humidity, atmospheric pressure, wind speed, wind direction, rainfall, etc.) and arranged on a map, the weather changes from moment to moment. The situation of the shooting location at that time can be managed correspondingly, which can be useful for disaster prevention.

Second Embodiment
[Schematic configuration]
FIG. 5 is a functional block diagram of a digital camera 200b according to the preferred second embodiment of the present invention. Unlike the camera 200a according to the first embodiment, the camera 200b does not include the environment information sensor 151a, but instead includes a photographer information sensor 151b that measures the biological information of the photographer. Since other configurations are the same as those of the digital camera 200a according to the first embodiment, details are omitted. Of course, the camera 200b may include both the environment information sensor 151a and the photographer information sensor 151b. The camera 200b does not include the search unit 112a, the GPS device 159, and the gyro sensor 158, but may include these.

  The photographer information sensor 151b is a sensor that acquires biological information (hereinafter referred to as photographer information) that can be physically measured from a photographer who operates the camera 200b. For example, the photographer information sensor 151b includes a body temperature sensor, a pulse sensor, a blood pressure sensor, an iris sensor, a fingerprint sensor, a sweat sensor (detects sweat, tears, etc.), an electroencephalogram sensor, or a part or all of these. The body temperature, pulse, blood pressure, brain wave, iris / fingerprint shape, or a combination of some or all of them is acquired as photographer information. The photographer information sensor 151b is not limited to the above configuration as long as it can obtain biological information that can be physically measured from the body of the photographer.

  The photographer information sensor 151 b outputs photographer information to the CPU 112 in conjunction with the half-pressing operation of the shutter button 102. The CPU 112 records the photographer information in a predetermined tag (such as an image description tag) in the header portion of the Exif file in conjunction with the release of the full press operation of the shutter button 102. That is, the photographer information is also included in the example of the image supplementary information described above.

  If the camera 200b is connected to the counting center 300, the camera 200b can be used in a shooting game for competing for the coolness of the photographer during shooting. Hereinafter, the flow of the shooting game using the camera 200b will be described with reference to the flowchart of FIG.

  The photographer who brought the camera 200b is one or more installed at a predetermined position in the facility where the photographer patrolls and passes through a certain process such as a maze, a roller coaster, a haunted house, and a waterway by boat. The shooting target is shot by half-pressing / full-pressing the shutter button 102 of the camera 200b (S11). In the storage medium 40, the image of the shooting target and the photographer information are recorded in an Exif file. FIG. 7 shows a state where the photographer P takes a check point indicating a branch point at a branch point of a maze, which is an example of a facility, with the camera 200b.

  The photographer sequentially captures the imaging targets T encountered during patrol / passage of the facility, and repeats this until the tour of the facility is completed (S12).

  When the patrol / passage of the facility is completed, the photographer performs a predetermined operation on the operation unit 157 and transmits all Exif files stored in the storage medium 40 to the counting center 300 via the communication unit 156 (S13). . The connection between the totaling center 300 configured by a personal computer and the communication unit 156 may be various connection forms such as a USB connection. The storage medium 40 may be brought to the aggregation center 300 and the aggregation center 300 Exif file may be read from the storage medium 40.

  The scoring unit 301 of the counting center 300 scores an image corresponding to the photographer information based on the photographer information recorded in the Exif file received from the camera 200b (S14). The scoring is done as follows. Based on the photographer information recorded together with the photographed image of the photographing target T, the scoring unit 301 determines the degree of calmness of the photographer when photographing the image corresponding to the photographer information, in other words, the degree of shaking. Score as "coolness". For example, if the values of blood pressure, pulse, sweating, and body temperature included in the photographer information are small, more points are added. On the other hand, based on the photographer information, the scoring unit 301 scores the photographing accuracy of the image corresponding to the photographer information. For example, when the inclination detected by the gyro sensor 158 is a substantially predetermined angle (for example, 0 ° C., so-called horizontal shooting or 90 ° C., so-called vertical shooting), or when the acceleration detected by the acceleration sensor is approximately 0, that is, there is no camera shake. Will be scored for accuracy.

  Note that the appropriateness of the shooting position of the shooting target, the shooting size of the shooting target, and the appropriateness of the focusing may be visually confirmed by the counting staff of the counting center 300 and scored as “accuracy”. Additional points may be added according to the number of images in which checkpoints in the same maze are photographed, and if the same checkpoints are not photographed repeatedly, it may be assumed that the maze is lost and many points are added.

  The scoring unit 301 performs scoring for all images received from the camera 200b, sums the scores of each image, and finishes scoring using the total score as a scoring result. When the scoring is over, the scoring result is transmitted from the counting center 300 to the camera 200b. When the communication unit 156 receives the scoring result, the camera 200b displays it on the image display device 110 (S15). The scoring result may be displayed on the display unit 302 of the counting center 300 configured by a liquid crystal monitor or the like.
