Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera that is provided with a GPS receiver as a positioning device and records positional information at the time of photographing together with the photographed image.

[Conventional technology]

Conventionally, when taking photos with a silver halide camera, the date and time of the photo taken,
It has been proposed that the aperture value Av, shutter speed Tv, etc. are stored as photographic information for each frame in a semiconductor memory built into the film container in association with the photographed image (
JP-A-1-289948).

Additionally, a camera that stores captured images on a removable memory card has already been proposed (Japanese Patent Laid-Open No. 63-274
No. 289 Publication), and furthermore, the images stored in the memory card obtained in this manner are transferred to a filing system (DA
There is also a known system in which information is transferred to a computer (e.g. T), and search information is added at the time of the transfer to facilitate subsequent searches using a personal computer or the like.

In addition, as a positioning system, Loran, Omega,
In recent years, NN5S has been widely used in the Detsuka system. Furthermore, recently GPS (Global Po
sitioning systems) are increasingly being used. As is well known, GPS is a high-precision positioning system that receives transmitted data from at least four artificial satellites with a receiver on the ground, and determines the three-dimensional position of the receiver from the received data. Japanese Patent Publication No. 1-31
An example of the configuration of a GPU receiver (aimed at eliminating swing errors) is described in Japanese Patent No. 2483.

[Problem to be solved by the invention]

In the camera described in Japanese Patent Application Laid-Open No. 1-289948, it is possible to use the sensor originally built into the camera and store data obtained from the sensor in correspondence with the photographed image, but other data cannot be stored. For example, the user must input data such as audio and shooting location manually each time a photo is taken, which is not always convenient.

Furthermore, even in the device that transfers data to the filing system, the memory card itself is not configured to input search information, and therefore, the addition of search information must be performed manually for each transfer, as described above. I have this problem.

Furthermore, regarding the latter invention related to a GPS receiver, the G
A PS receiver is not provided in the camera, and therefore there is no description of how to handle or process positioning data on the camera side.

The present invention has been made in view of the above, and it is an object of the present invention to propose a camera that records position data obtained by a GPS receiver together with a photographed image as photographing position information.

[Means to solve the problem]

The present invention provides a camera that records captured images using GPS.
The apparatus includes a receiver, a recording means for recording positioning data obtained from the GPS receiver, and a recording control means for recording the positioning data in correspondence with a photographed image in the recording means.

[Effect]

According to the present invention, images taken with a camera are recorded on film, memory, or the like. On the other hand, the positioning data obtained by the GPS receiver is guided to the camera, and is automatically recorded in the recording means such as the film or memory in association with the photographed image at that time.

〔Example〕

FIG. 1 shows an example of a block diagram of a camera that captures images.

In the figure, a lens 1 to an encoder 8 are configured for photographing images.

The AD comparator 4 converts the input analog image signal into a digital image signal. White balance correction circuit 5
The digital image signal is subjected to white balance correction based on color temperature data from a white balance sensor 14, which will be described later, and the γ correction circuit 6 further performs γ correction. Furthermore, the matrix processing circuit 7 performs predetermined gradation correction on the digital image signal. The encoder 8 encodes the input digital image signal into an NTSC signal for reproduction images.

The microphone 10 to the memory 13 are configured for voice input.

A microphone 10 is provided at a suitable location on the camera body and captures the voices of the photographer, the person to be photographed, and the like.

The amplifier 11 amplifies the audio signal from the microphone 10 by a predetermined amplification factor, and outputs it to the next stage AD converter 12. The AD converter 12 converts the input analog audio signal into a digital audio signal. The memory 13 is used for voice recording (for speaker recognition), and temporarily stores input digital voice data, and then stores the input digital voice data in the memory card I/O.

Next, a configuration for importing various other information will be explained.

The white balance sensor 14 detects the color temperature of the subject, and determines from the obtained color temperature data whether the photograph was taken under fluorescent light or sunlight, and selects the appropriate one. Apply white balance. The AF sensor 15 is used to calculate the distance to the subject using a known distance measurement method, and for example, separates the subject image that has passed through the lens 1 into two directions and sends the image to each light receiving section (not shown). It is configured to guide the image of the subject. The subject images obtained by the two upper light receiving sections are input to the AFCPU 16, and the AFCPU 16 calculates the phase difference from the subject images of the above two light receiving sections, and calculates the distance to the subject image from the phase difference. Calculate.

Furthermore, the AFCPU 16 drives a lens drive system (not shown) based on the calculated distance data to move the lens 1 to the in-focus position. When the movement to the in-focus position is completed, focal length data f from the lens 1 and subject distance data D from the AFCPU 16 are output to a control unit (hereinafter referred to as CPU) 20, which will be described later.

The temperature sensor 17, the humidity sensor 18, and the atmospheric pressure sensor 19 are for measuring the temperature (air 21), humidity, and atmospheric pressure, respectively, during photographing. Each measured data is sent to CPU2
Output to 0. Each of the above-mentioned sensors automatically measures each data during photographing and guides it to the CPU 20.

The reception tuning section 21, the demodulation section 22, and the GPS receiver 23 are configured to obtain position information. The reception tuning unit 21 generates a code (
The demodulator 22 receives FM radio waves containing codes indicating regions, tourist spots, events, etc. (hereinafter referred to as location codes), and the demodulator 22 demodulates the received FM signals to reproduce location code data and send it to the CPU 20. Output. Note that details will be explained with reference to FIG. 2. On the other hand, the GPS receiver 23
The antenna 23a receives radio waves from a satellite (not shown), calculates the latitude, longitude, and degrees of the current position, and outputs the calculated values to the CPU 20. Details will be explained in FIG. 3.

The clock section 24 is for clocking the date and time built into the camera body.

The operation and control system is performed by the CPU 20 and each operation switch 8.
It is comprised of an operation and display unit 25 that outputs the operation states of S1 to S3 to the CPU 20.

The CPU 20 is a microcomputer that centrally controls the operations of the various parts of the camera described above. The photographing preparation switch S1 starts the operation of each of the sensors. The exposure start switch S2 is a so-called release button that starts the exposure operation of the camera. Preferably, the photographing preparation switch S1 is activated when the release button is pressed halfway, and the exposure start switch S2 is activated when the release button is pressed fully. Further, the operation and display section 25 outputs the switching states of the switches 81 to S3 to the CPU 20, and displays various data from the CPU 20 at the time of photographing, such as frame numbers, as necessary.

Further, the memory card I/F 9 is an SRAM or E2 PROM that can be attached to and detached from the camera body to store the image data, audio data, and various shooting information under the control of the CPU 20.
It also outputs the usage status of the memory card 26 (presence or absence of storage area, etc.) to the CPtJ 20.

The photographic information stored in the memory card 26 is used as search information during filing, as will be described later.

Figure 2 explains the location code transmitting and receiving device.
In the same figure (A> indicates a transmitter that is installed in each region, tourist spot, event venue, etc. and transmits the location code, and in the same figure (B)
) indicates a receiver installed in the camera body that receives the location code.

In FIG. 2A, a ROM 201 has a location code, for example, a location (event) identification code, a Kanji JIS code string of a location (event) name, or both previously written therein. The DPSK modulation section 202
Differential phase modulation (DPSK) is applied to the carrier wave using the output code data from OM201.
hase 5htft KeVinQ). The FM modulator 203 applies FMI[Il to the carrier wave according to the input serial data, and further applies the FMI[Il to the carrier wave using the input serial data.
After being amplified to a predetermined power, the signal is transmitted from the antenna 205 as an FM radio wave including a location code.

The timing generation circuit 206 controls the timing of each block on the transmitter side, and the ROM 201 stores address data for reading, and the DPSK modulation section 202 and FMi[
A clock pulse CK is output to the section 203.

Note that the DPSK modulation is performed by the timing generation circuit 20.
6 clock pulses CK are used to extract phase difference data from digital data by AFM in the audible range, MFM in medium waves, PLL method, etc., and convert it into serial data.

Next, in Figure (B), the antenna 21a receives the FM radio wave of the location code transmitted from the antenna 205 on the transmitter side, and the received signal is amplified by the amplifier 207 and input to the FMI adjustment section 208. Ru. The received signal is FMv
The main 208 frequency is removed in the 11i section 208, and further demodulated into the original code data in the next stage DPSK demodulation section 209. The CPU 20 takes in the demodulated code data and stores it in the memory card 26. That is, C.P.
U20 writes the code data to the memory card 26 in association with the writing of the photographed image at that time. The timing generation circuit 210 controls the timing of each block on the receiver side, and operates the FM demodulation section 208 and the DPSK demodulation section 209 according to a control signal from the CPU 20.
A clock pulse CK is output to.

Therefore, when a camera image is taken at a location where the transmitter is installed, such as a certain area, tourist spot, or event venue, the location code is automatically stored in the memory card.

The ROM 201 may be one that stores only a location code specific to that location, or one that has multiple location codes written in advance and can be switched to output the location code depending on the installation location. But that's fine.

FIG. 3 is a detailed block diagram of the GPS receiver 23.

The antenna 23a is, for example, a quadrifilar heix type which receives transmitted radio waves from a NAVASTAR satellite (not shown).

RF signal mixer 23 received by this antenna 23a
It is input to 0. On the other hand, the modulator 231 is the local oscillator 23
The local oscillation signal CK1 from 2 is sent to the PN code generator 233.
The spread modulation signal is input to the mixer 230. As a result, the IF multiplied signal, which is the intermediate frequency of the RF multiplied signal, is converted and inputted to the data demodulation circuit 234.

This data demodulation circuit 234 demodulates data including the time when the satellite transmits the signal from the input signal. The demodulated data is input to a data processing circuit 235 and a delay measurement circuit 236.

The delay measurement circuit 236 first outputs a timing signal to the PN code generator 233 when demodulated data is input. The PN code generator 233 always generates PN by the clock pulse CK2 from the PN code clock generator 237.
A code is generated, and when the timing signal is input, the generated PN code is sent to the delay measurement circuit 236. And data demodulation circuit 234
PN code from and PN from PN code generator 233
The code is led to a delay measuring circuit 236, and the delay time of the PN code necessary for correlation between both PN codes is measured. The delay time of this PN code is determined by the measurement clock generator 238.
The counted value is outputted from the delay measuring circuit 236 to the data processing circuit 235 as delay data necessary for correlating both PN codes.

The data processing circuit 235 is composed of a microprocessor and is driven by the clock pulse CK4 from the data processing clock generation circuit 239, and includes transmission time data included in the demodulated data from the data demodulation circuit 234 and a built-in GPS receiver. Determine the radio wave propagation time from the satellite to the GPS receiver (camera) from the reception time data obtained from a cesium and rubodium vapor atomic clock (not shown),
The distance from the satellite to the GPS receiver (camera) is calculated from this time. Then, the data processing circuit 235 calculates and calculates the position information regarding the latitude, longitude, and altitude of the camera (INN viewer) from the distance information from each satellite and the position information of each satellite itself included in the demodulated data. ,
Output to CPU 20.

As is well known, GPS is a system that covers the whole world with eight NAVASTARs, but currently not all satellites have been launched, and there are areas where reception is not possible or where it is not possible to receive it depending on the time of day. The CPU 20 automatically stores location code data from the location code receiver in areas where reception is not possible, while storing data from the satellite when no location code transmitter is installed and no location code is received. Both receivers are controlled so that they receive data, take in the received data as position information, and interpolate each other.

FIG. 4 is a flowchart explaining the operation of the camera.

In step #1, wait for the power (not shown) to be turned on,
When the power is turned on (YES in step #1), the presence or absence of the memory card 26 is determined (step #2). If there is no memory card 26, a message "No card" is displayed and a warning that photographing (recording) is not possible is displayed, and the process returns to step #1 (step #3, step #4). In this case, the camera may have a memory capable of recording a plurality of frames in addition to the memory card 26.

If the memory card 26 is installed, "card present" is displayed (step #5), and then the usage status of the memory card 26, that is, the presence or absence of recordable free space is detected (step #6). ). If there is no free space (
(YES in step #7), a warning is issued indicating that recording is not possible, and the process returns to step #1. Note that, as described above, when a built-in memory for a plurality of frames is provided, whether or not recording is not possible may be determined in consideration of the presence or absence of free space in the built-in memory.

On the other hand, if recording is possible (NO in step #7), it is determined whether or not the photographing preparation switch S1 is on (step #9). If the switch S1 is not on (No in step #9), it is determined that the camera is not shooting and the process returns to step #1; if it is on (YES in step #9), the process moves to step #10. Then, various operations and processes for preparing for shooting are performed. Specifically, the AF sensor 15 measures the distance to the subject, the WB sensor 14 measures the color temperature of the object, the temperature sensor 17 measures temperature, the humidity sensor 18 measures humidity, the air pressure sensor 19 measures atmospheric pressure, and the GPS receiver 23 measures the temperature. positioning and location code reception 11121.22 including location code F
The M radio waves are received sequentially (step #10 to step #16). In the above steps, all photographic information from each sensor etc. is input, but a switch not shown may be used to select desired photographic information so that only desired photographic information can be input.

When the input operation of shooting information from each of the above sensors etc. is completed,
Next, it is determined whether or not the exposure start switch S2 is on (step #17). Above switch S2
If not on (No in step #17), the process advances to step #18, and the state of switch S1 is checked again. Here, if switch S1 is on (step #1
If the switch S1 is off (No in step #18), the process returns to step #10 and sensing is performed again using the sensors, etc., in order to obtain more accurate photographic information immediately before the photograph is taken. ), it is determined that photography has been canceled and the process returns to step #1.

If switch S2 is on (YES in step #17)
), the distance measurement data is locked, and then focal length information f from the lens 1 and object distance information from the AFCPU 16 are stored (step #19 and step #20).

Then, the colorimetric data obtained by the WB sensor 14 is locked, and then the voice input operation using the microphone 10 is started (Step #21. Step #22). Further, in parallel with this operation, exposure is performed (step #23), and when the exposure is completed (YES in step #24), predetermined signal processing for capturing the photographed image is started (step #25). .

Next, in step #26, turn on the audio input selector switch $3.
It is determined whether or not the switch S3 is on, and if the switch S3 is on (YES in step #26), all audio is captured (step #27), and if it is not on (no in step #26), For example, audio is captured for one second for recognition (step #28).

After the above operations, image data, acoustic data, and search information (I! shadow information) obtained from each sensor are written in the memory card 26 in a corresponding format (see Figure 27) (step #29). Then, the free space information on the memory card 26 is updated, and the frame number is counted up by 1 (steps #30 and #31) in preparation for the next photographing.

FIG. 5 is a block diagram showing an example of a photographed image playback device equipped with a search function.

This reproducing machine is centrally controlled by a CPU 50. This CPU 50 is programmed in advance to perform various control functions in accordance with the content of each search and reproduction process described later.

The memory card I/F 51 is used to guide recorded images, search information, and data regarding the usage status of the memory card 26 from the memory card 26 to the playback device, and also to guide read image selection data from the playback device to the memory card 26. This is the interface. The special reproduction processing unit 52 performs special processing on the image read from the memory card 26 as described later, and the image data processed by the special reproduction processing unit 52 is stored in the -H image frame memory 53. .

The combining unit 54 combines image data with a superimposed image, which will be described later, and is switched and controlled by an on-screen display 0N10FF switching control signal from the CPU 50. The combined image signal is sent to the DA converter 55
The signal is converted into an analog signal at , and further amplified at the next stage amplification 56 , and then guided to a TV monitor 57 for reproduction and display.

The superimpose memory 58 stores various search information and on-screen display patterns such as scales. The successive clock generation circuit 59 supplies clock pulses for read timing to the image frame memory 53, the synthesis section 54, the OA converter 55, and the superimpose memory 58, respectively.

The character generator 60 stores the character font of the Japanese Industrial Standard JIs code string, and outputs the corresponding character code to the CPU 50 when the JIS code string is adopted as the location code. The filing device 61 is composed of a recording medium such as an optical disk and its driving circuit, and is a so-called album that appropriately records recorded images in the memory card 26. This filing device 6
1 is controlled by the CPU 50 to read and write 11J, records images and registration search information, and outputs registration search information and disk management information to the CPU 50.

The keyboard 62 is used for inputting and modifying search information, and also for specifying the position of the search information recorded in the filing device 61, especially maps and place names. It is connected. The voice input unit 64 is used to input voice when registering voice for search, and the speaker data E2PROM 65 is used to encode the input voice when registering voice and record it as registered voice.

In addition, the audio data memory 66 is connected to the memory card I/F 51.
It temporarily stores the audio recorded on the memory card 26 that is input via the DA converter 67.
, and is guided to a speaker 69 via an amplifier 68 and reproduced as audio. The speaker recognition unit 70 receives voice data input via the memory card I/F 51 and the E2PRO for the speaker data.
This is to determine whose voice the voice is by comparing it with speaker data registered in the M65. The judgment result for this speaker is CP
It is also output to U50 and used as an index during a search.

Note that 71 to 73 are printers, facsimile machines, and video telephones for transmitting and outputting stored images and search images.

In the above configuration, next, the processing on the playback machine side is shown in Figures 6 to 2.
This will be explained using the flowchart shown in FIG.

First, a procedure for registering images in the memory card 26 in the filing device 61 will be explained with reference to FIG.

When the memory card 26 is inserted into the player (step #
41), the recorded images in the memory card 26 are sequentially read out (step #42). The recorded images that are successively reproduced are reproduced for multi-screen use by the special reproduction processing section 52, and then displayed on the TV.
Multi-display is performed on the monitor 57 (step #43). Multi-display is performed by allocating a predetermined number of frames to one frame, or a number of frames set according to the number of recorded images in the memory card 26.

Next, the CPU 50 accepts the selection of an image desired to be registered in the filing device 61 from among the images in the multi-screen,
Next, the frame number of the corresponding image is input using the keyboard 62 or the like to select it (step #44), and the multi-image display is performed again for the selected image (step #44).
Step #45). Next, in step #45, it is determined whether the search information input on the camera side is to be modified or added. Examples of such corrections and additions include correcting a person's name when the result of speaker identification is displayed incorrectly, correcting position information, and adding comments.

If there is no modification of the search information (N in step #46)
Step #47: By performing a registration operation on the keyboard 62, the image and search information are recorded in the filing device 61, and the recorded image and search information are deleted from the memory card 26. #
48). This erasing operation creates a free space in the memory card 26, making it possible to record new captured images.

On the other hand, if there is a correction etc. (YES in step #46),
When an image that requires correction or the like is selected using the keyboard 62 or position indicating member 63, the image and search information are displayed on the TV monitor screen (step #49, step #5).
0). The user makes necessary corrections and additions while looking at the screen (Step #51). Every time the correction, etc. of one image is completed, the user is asked whether or not corrections, etc. are necessary for the other images (Step #51). Step #46 from 51
). When the necessary corrections and the like are completed, the process moves to step #47 and the registration process ends.

Next, the procedure for registering audio will be explained with reference to FIGS. 7 and 8.

Fig. 7 shows the procedure of "Voice Registration Technique" which registers a voice and a person's name in association with each other, and Fig. 8 shows the procedure of "Voice Registration IIJ" which registers only the voice.
1, or may be provided as a separate voice registration mode.

In FIG. 7, first, after the CPU 50 enables reception of voice input, voice is input from the microphone of the voice input unit 64 (step #61), and the input voice is transmitted to the AD.
It is converted and encoded (steps #62, #63).

This encoded voice data is used for E2P recording of speaker data.
It is registered in the ROM 65 (step #64). continue,
The CPU 50 can accept data from the keyboard 62, and when the speaker's name is input from the keyboard 62 (step #65), it is encoded (step #66).
, and is further associated with the voice data of the speaker and E2PR.
It is registered in OM65 (step #67).

Therefore, as will be described later, when searching by voice, the person's name of the speaker is superimposed on the TV monitor 57 along with the search image by superimposition.

In FIG. 8, first, after the CPU 50 is enabled to accept voice input, when voice is input from the microphone of the voice input section 64 (step #71), the input voice is AD converted and encoded. (Steps #72, #73). This encoded audio data is stored in the E2P for recording speaker data.
It is registered in the ROM 65 (step #74).

Therefore, only the searched image will be displayed on the TV monitor 57 when searching by voice.

Next, various search procedures will be explained with reference to FIGS. 9 to 21.

FIG. 9 shows the main flow of the search process.

First, select which item (condition) to search using the keyboard 62.
etc., the CPU 50 collates the search item with each image or search information (step #81), sequentially reads matching images from the memory card 26, and displays them on the TV monitor 57 in multiple formats (step #82). and,
The user selects one or more desired images from among the multi-displayed images (step #83).

When the selection for the current display screen is completed, it is determined whether all other multi-screens that display images that match the search items have been displayed (step #84), and if there are other multi-screens, the current screen is will be updated to the next screen (step #
85). Then, when image selection is completed for the multi-screen to be updated (Y in steps #83 and #84)
ES), the selected image is output in a desired output format as described below (step #86).

FIG. 10 shows a flowchart of [Item Search J] for the search items shown in step #81.

In this example, the search items are "location" and "date and time."
Examples include "weather,""people'snames,""indoors and outdoors,""views of people,""events," and "sounds."

When “Item Search” starts, first, “
An inquiry is made as to whether or not to select "Location" (step #91). When the "location" is selected, the "location search" flow shown in FIG. 11 is executed (step #92
). If it is not selected, then an inquiry is made as to whether or not to select "date and time" as a search item (step #9).
3).

When "Date and time" is selected, "Date and time search" shown in Figure 12
The flow is executed (step #94).

If it is not selected, then an inquiry is made as to whether or not to select "weather" as a search item (step #95).
. When "weather" is selected, the "weather search" flow shown in FIG. 13 is executed (step #96). If it is not selected, then an inquiry is made as to whether or not to select "person's name" as a search item (step #97). When "One Person's Name" is selected, the flow of "Person Name Search" shown in FIG. 14 is executed (step #98). If not selected,
Next, an inquiry is made as to whether or not to select "indoor/outdoor" as a search item (step #99). If "indoor/outdoor" is selected, the "indoor/outdoor search" flow shown in FIG. 16 is executed. (Step #100). If it is not selected, then an inquiry is made as to whether "portrait scenery" should be selected as a search item (step #101). "Portrait Landscape"
When is selected, the flow of "person/scenery search" shown in FIG. 17 is executed (step #102). If it is not selected, then an inquiry is made as to whether or not to select "event" as a search item (step #103). When "event" is selected, the "event search" flow shown in FIG. 19 is executed (step #104). If it is not selected, then an inquiry is made as to whether or not to select "audio" as a search item (step #105).

[When voice j is selected, "Voice search" shown in Figure 20
The flow is executed (step #106). continue,
Re-selection is made possible in consideration of changes or additions to search items (NO in step #107). Thereafter, the "item search" process is ended and the process returns to step #82.

These search items depend on each sensor on the camera side, and it is also possible to select two or more items at the same time.

The details of each of the above search processes will be explained below with reference to FIGS. 11 to 21.

In the flow of "location search" shown in FIG. 11, the location code and/or GPS positioning data serve as an index of location information.

First, it is determined whether a map is required to be displayed on the TV monitor 57 (step #111). When displaying a map, that is, when indicating the shooting location on the map, use the filing device 6.
1 or the built-in memory (not shown) of the CPU 50, or the removable map-dedicated memory (also not shown) to be displayed on the TV monitor 57 (step #112), and the position of the mouse, etc. The member 63 specifies a position on the displayed map (step #113).

The indicated position data (11 degrees, longitude) is calculated based on the displayed map and the output position signal of the position pointing member 63.

Alternatively, the detection may be performed using a tablet or the like, for example. On the other hand, if map display is not required, place names and places recorded in association with recorded images are read out and displayed, and a desired place name, etc. from among the displayed place names, etc. is inputted from the keyboard 62 to specify it. (Step #1
14, #115). Subsequently, the CPU 50 searches for an image matching the specified position or input place name, etc. (step #116). This search is performed by scanning search information recorded in association with each image. When the search is completed, the number of matching items is displayed as the search result (step #117). At this time, the frame number of the corresponding image may be displayed. After this, it is determined whether a re-search is necessary (step #118
). Examples of re-search include a case where the number of matching items is large or, conversely, a case where the number of matching items is zero. In the case of a re-search, if another search condition is input or specified, the search by the CPU 50 is performed in the same manner as above (steps #111 to #1).
17). Then, when the search ends, step #118
(No), return to step #93.

In the flow of "date and time search" shown in FIG. 12, the date information from the timer 24 serves as an index.

When the date and time, that is, the year, month, day, hour, minute, season, etc., are input from the keyboard 62, Step #121>, CP
U50 executes a search for images matching the input search conditions (step #122). This search is performed by scanning the search information (date and time data) recorded in association with each image, as described above. Note that the CPU 50 is provided with a storage unit that associates seasons with date and time data, and when the search condition is a season, the input season is converted into corresponding date and time data in the storage unit, and the corresponding date and time data is A search is performed using the converted date and time data.

When the search is completed, the number of matching items is displayed as the search result (step #123). Note that, as described above, the frame number of the corresponding image may be displayed. After this, it is determined whether a re-search is necessary (step #124). In the case of re-searching, if other search conditions are input, the search will be performed by the CPU 50 in the same manner as above (
Step #121 to Step #123). Then, when the search is completed (NO in step #124), step #
Return to 95.

In the flow of "weather search" shown in FIG. 13, the temperature and humidity information from the temperature sensor 17 and humidity sensor 18 serve as indexes.

Weather-related conditions, such as "sunny", "rainy", "hot"
, "It's cold", etc. are input from the keyboard 62 (step #131), and the CPU 50 searches for images matching the input search conditions by scanning the search information (step #132). The CPU 50 is provided with a storage means that stores in advance the correspondence between the above-mentioned weather-related conditions and weather data consisting of temperature and humidity. For example, if you enter "Ii", the temperature (ki 1) is 30℃.
The search may be performed based on a certain predetermined temperature and humidity, such as those listed above or those with a humidity of 180% or higher.

Furthermore, the reference temperature and humidity may be changed depending on the location, date and time (and season). For example, if you want to search for "summer + hot", the temperature must be 30 degrees Celsius or higher, and 7 or 8 degrees Celsius.
For September, on the other hand, for "winter + hot" the temperature is 25℃.
The above is the one for December, January, and February.

When searching, the input weather-related conditions are converted into corresponding weather data in the storage means, and the search is performed using the converted weather data.

When the search is completed, the number of matching items is displayed as the search result (step #133), and it is then determined whether a re-search is necessary (step #134). If you want to search again, enter other search conditions and the CPU
50 is performed (steps #131 to #133).

Then, when the search is completed (NO in step #134)
, return to step #97.

In the flow of "person name search" shown in FIG. 14, "voice" or "person name" serves as an index.

When a "person's name" is input from the keyboard 62 (step #141), the CPU 50 searches for images matching the input search conditions (step #142). This process is performed according to "search process (■)" shown in FIG. That is, first, it is determined whether the search is by "voice" or by "person's name" (step #151). “Voice J
In the case of a search, the input person's name is encoded and converted into a person's name code, and the voice code corresponding to the person's name code is extracted from the E2PROM 65 (step #15).
3, #154). Next, the audio data recorded in association with the pre-registered image is extracted from the filing device 61 and encoded (step #155).
, #156).

Then, the audio code from the E2FROM 65 is compared with the audio code from the filing 8161 (step #157). This verification is done by the filing device 161.
This is performed for all images by sequentially scanning the audio chords of the images registered in the image (NO in steps #156 to #158, loop of step #159). When the matching for all images is completed, select Y in step #158.
ES), return to step #143. On the other hand, if search by person name is selected in step #151,
The person name code input at the time of image registration in the filing device 61 is scanned and searched (step #152). When the search is completed, the process returns to step #143.

Returning to FIG. 14, the number of matching items etc. are displayed as the search results (step #143). After this, it is determined whether a re-search is necessary (step #144). If you want to search again, enter other search conditions and click CP in the same way as above.
A search is performed by the LI 50 (steps #141 to #143).

Then, when the search is completed (No in step #144)
, return to step #99.

In the flow of “indoor/outdoor search” shown in Figure 16, W
The output from the B sensor 14 becomes the index.

When either "indoors" or "outdoors" is selectively input from the keyboard 62 (step #161), the CPU 50 searches for images that match the input search conditions by scanning the search information. (Step #162). C.P.
In LI50, there is a correspondence between the above search conditions and the output of the WB sensor (color temperature data), for example, "indoor" for color temperature data corresponding to under fluorescent light, and "indoor" for color temperature data corresponding to under sunlight. A storage means is provided for storing the data as "outdoor". At the time of a search, one of the input "indoor J" and "outdoor J" is converted into corresponding color temperature data in the storage means, and a search is performed using the converted color temperature data.

When the search is completed, the number of matching items etc. are displayed as the search results (step #163). After this, it is determined whether a re-search is necessary (step #164). If you want to search again, enter other search conditions, and then click CPL in the same way as above.
150 is performed (steps #161 to #163).

Then, when the search is completed (No at step #164)
, return to step #101.

In the flow of “person scene search” shown in Figure 17,
Focal length fJ and object distance DJ information (image magnification β
=f-D) becomes the index.

First, select either "person" or "landscape" on the keyboard 62.
When input from step #171), the CPU 50 executes a search for images matching the input search conditions (step #171).
Step #172). This process is performed according to "Search Process ■" shown in FIG. That is, first, all focal lengths f and subject distances recorded in correspondence with images registered in advance in the filing device 61 are read out, and each image magnification β-f-D for all images is calculated ( Step #181). Subsequently, each obtained image magnification β is β≧1/
100 or not (step #182), β≧1
/100, it is considered a landscape Step #1
84), and in the opposite case, it is determined that the person is a person (step #183). Then, the CPU 50 selects “
When "person" is input, the result of step #183 is extracted, and when "-" is input, the result of step #18 is extracted.
Extract the results of step 4.

Note that as a matching method, discrimination may be performed for each image as described above, and such discrimination may be sequentially repeated.

When the determination for all images is completed, the process returns to step #173.

Returning to FIG. 17, the number of matching items etc. are displayed as the search results (step #173). Thereafter, it is determined whether a re-search is necessary (step #174). If you want to search again, enter the other search condition, and click C in the same way as above.
A search is performed by the PU 50 (steps #171 to #173). Then, when the search is completed, the result in step #174 is No, and the process returns to step #103.

In addition, in the above embodiment, the image magnification β, "person", "landscape"
Although the association between the image magnification β and "person" and "landscape" is stored as a program, a storage means may be provided in the CPLI 50 in which the image magnification β and "person" and "landscape" are stored in association with each other. Another search method is to obtain the image magnification β from the recorded focal length f and subject distance, and then predetermine the range of the image magnification β for the input “person” and “landscape”. , the search may be performed by determining in which range each image magnification β to be searched is included.

In the “event search flow” shown in Figure 19,
The location code (event code) becomes the index.

When an event name is input from the keyboard 62 (step #191), the CPtJ 50 searches for images matching the input search conditions by scanning the event code recorded in association with the image registered in advance in the filing device [61]. This is done by doing this (step #192). When the search is complete, the number of matching items will be displayed as the search results (
Step #193). Thereafter, it is determined whether a re-search is necessary (step #194). In the case of re-searching, if you enter other search conditions, a search using CP (J50) will be performed in the same way as above (steps #191 to #1).
93). Then, when the search ends, step #194
(NO), return to step #105.

In addition, if the location code is an identification code for the location or a JIs code string of characters that displays information about the location, it will be possible to search directly using the code, and when shooting, the content of the location code will be recorded as is without having to distinguish it. It becomes possible to do so. Furthermore, since no special determining means is required to determine the content of the location code, the configuration of the search side, for example, can be simplified accordingly.

In the flow of "voice search" shown in FIG. 20, the voice recorded in association with the image is compared with the voice input during the search.

When voice is input from the microphone of the voice input unit 64 (step #201), the CPtJ 50 searches for an image that matches the input voice (step #192). This process is performed according to "Search Process ■" shown in FIG. That is, first, the input voice is AD converted,
After being encoded, it is stored in a reference unit (not shown) (steps #211 to #213). Next, the audio data recorded in association with the pre-registered image is extracted from the filing device 61 and encoded (
Steps #214, #215). Then, the audio code from the reference section is compared with the audio code from the filing device 61 (step #216). This verification is performed for all images by sequentially scanning the audio codes of the images registered in the filing device 61 (step #215 to step #217, NO1 step #218 loop). When the verification of all images is completed (YES in step #217), the process returns to step #203.

Returning to FIG. 20, the number of matching items is displayed as the search result (step #203). After this, it is determined whether a re-search is necessary (step #204). In the case of re-searching, if another word is input by voice, the search is performed by the CPU 50 in the same manner as above (step #201).
~Step #203). When the search is completed (No in step #204), the process returns to step #107.

Next, returning to FIG. 9, the execution process of step #86 will be explained using FIG. 22.

In this execution mode, first, the output format is selected. Table 1 shows this output format.

Table 1 (hereinafter referred to as blank space) That is, after the search is completed, one output form is selected from the output forms A to F of the clothes 1, and the keyboard 6 is pressed.
2, for example, when a corresponding character is input (step #221), the number of output images that are the search results is set to N (step #222), and then the images to be output are sent to the filing device in ascending order of frame number. ! 61 and sequentially transferred to the frame memory 53 (step #2
23). Next, the image is output according to the output format selected in step #221. If output format A is selected (YES in step #224), it is displayed on the TV monitor 57 as is. If output format B is selected (YES in step #225), data regarding the size of the subject on the imaging surface, that is, the scale size, is determined from the information on the focal length f and subject distance of the image, and the image and The scale size is combined (steps #226, #22
7>.

That is, the scale size is superimposed with the image in the composition section 54 and output to the TV monitor 57.

For example, when displaying a unit scale (see Figure 24 (B)), the scale size marked on the unit scale SC is the focal length, and the length per unit scale is calculated from the image magnification β calculated from the subject distance. is calculated. Here, regarding the calculation of the length of the unit scale SC, the 23rd
This will be specifically explained using the principle diagram in the image formation state shown in the figure.

In the figure, shi indicates the shooting distance, from the subject 100 to the imaging plane 200.
f is the focal length of the photographic lens 300, H is the interval between principal points of the photographic lens 300, X is the distance from the subject 10o to the front focal point of the photographic lens 300, and X' is the imaging surface 20.
0 to the rear focal point of the photographing lens 300, y is the length of the subject 100, and y- is the subject 1 on the imaging plane 200.
00 image length, and each of the above variables 1. f, @, x, x
Between y and y=, V:V-=x:f=f:x--・--(1)x-
= L −2f −H−x −・・・= (
There is a relationship 2). From these equations (1) and (2), X2
− (L−2f−H)x+f2 =O−−−−・−(3
) holds true. Finding the roots of this equation (3), we get: Using this, it becomes X'-((L-2f-H)-L-2-H)-4f)/2... (5). Also, from the above formula (1), y−y−・x/f ・・・・・・(
6) V-V -'r/x-... (7) Therefore, based on X and X= in the above equations (4) and (5), this equation (6) or (7) By calculating the formula, the length y of the subject corresponding to the length y' of the image on the imaging surface can be found. Here, if the length y' of the image on the imaging surface is treated as the length of the unit scale SC, the actual length of this unit scale (on the imaging surface) is known in advance, so (6)
The scale size of the unit scale SC is obtained by calculating the equation or (7).

FIG. 24 shows an example of displaying the scale size.

4A is a display example in which the image magnification is displayed as is, and FIG. 2B is a display example in which the unit scale SC corresponds to 10 cm.

By displaying such a scale size, the actual size of the image can be easily grasped. Furthermore, since the display timing of the scale SC can be freely changed by the readout clock generator 59 controlled by the CPU 50, the scale SC can be moved to a desired position using, for example, a trackball (position specifying member 63). If you can do this, it will be easier to operate.

Furthermore, it is easy to turn on and off the scale display, and the display formats shown in FIGS. 3A and 3B may be freely switched.

In addition, by using the technique described in JP-A-58-158507 to imprint the scale onto the silver halide film, it is possible to make the display of the scale size applicable to the silver halide film as well. I can do it.

Next, if output form C is selected (step #228
YES), and the display screen size (for example, CRT inches, etc.) is input from the keyboard 62 (step #2).
29>. Subsequently, the image size is changed based on the image magnification determined from the focal length f and the subject distance, and the display screen size (step #230>. That is, the final image size is adjusted to the TV monitor 57 for the actual subject size. The display magnification (image size) of the displayed image size is displayed.
Alternatively, the size of the display image is changed and displayed so that the display magnification is fixed at a predetermined size regardless of the display screen size.

That is, the CPU 50 has a display magnification calculation means that calculates the display magnification of the reproduced image from the image magnification determined from the focal length f and the subject distance and the display screen size. The size of the image displayed on the TV monitor 57 with respect to the size of is determined. In addition, if the display magnification is set in advance, the ratio between the display magnification calculated by the display magnification calculating means and the set magnification is calculated, and the displayed image is enlarged or reduced according to this ratio. Image processing is performed to ensure this.

In the above, the final display magnification is displayed at an appropriate location on the TV monitor 57 as necessary.

By doing so, it is possible to easily grasp the actual size of the image displayed on the TV monitor 57.

Next, if the output format is selected (step #231
(YES), the image desired to be displayed in a composite manner is extracted by the item search shown in FIG. 10 (step #232). Then, a desired image is selected from among the images that match the search conditions (step #233). Subsequently, the image magnification of the first selected image, the image magnification of the second selected image, and both images displayed together are led to the special reproduction processing section 52, where, for example, a specific subject in both images is The image size is appropriately changed so that the image size is the same size, is written to the image frame memory 53, and is output to the TV monitor 57 (step #2
34). By doing so, the sizes of the objects in both images finally displayed together on the TV monitor 57 can be displayed as if they were the same size. Alternatively, if the image sizes of both images that are displayed together are made to match, the actual size of the subject in both images can be easily compared. Furthermore, as in the case of scale display, by moving (superimposing) the displayed image with a trackball (position specifying member 63) or the like, a composite photograph or the like can be enjoyed.

Note that it is also possible to combine the currently taken image and the previously taken photo using both magnifications, so that, for example, a cut-off photo can be reproduced as a completed photo.

Next, if output form E is selected (step #235
YES), the displayed image is led to the special reproduction processing section 52, where various special processing such as mosaic, negative/positive inversion, etc. are applied to the displayed image, and then output to the TV monitor 57 ( Step #236).

Next, if output form F is selected (step #235
(No), a predetermined number of images, such as 4, 9, or 16 images, are reproduced on one screen. The predetermined number of sheets may be selected in advance or as needed, or a desired number such as (2×3) sheets may be selected.

First, the frame number and number of images for which multiple reproduction is desired are stored (step #237).

Next, it is determined whether the number of images has reached the predetermined number (step #238), and if the number of images is the predetermined number, multi-processing is performed (step #239), and step #240
to move to. On the other hand, if the number of sheets is not the predetermined number, step #2
47. Note that details of the processing in the case of output form F will be described later.

Now, when one of the output formats A to F is selected and the image obtained under the selection is displayed on the TV monitor 57 (step #240), it is next determined whether audio is recorded for the displayed image. A determination is made as to whether or not (step #24
1). If audio is recorded, the audio corresponding to the displayed image is played back (step #242). Subsequently, it is determined whether the displayed image is to be printed or transmitted (steps #243 and #245). When a print instruction is issued, the displayed image is printed out by the printer 71, and when a transmission instruction is issued, the fax 72
The displayed image is transmitted using the TV phone 73 or the like (steps #244 and #246).

When printing or transmission of one sheet is completed, the number of output images N set in step #221 is decremented by 1 (unless output format F is selected),
Subsequently, it is determined whether the number N of output images is O (step #248).

If N=O, the process returns to step #221, the next image is displayed, and after the displayed image is printed or transmitted,
The value of N is decremented (steps #221 to #247>. This process is repeated for the number of output images, and then when N=0, Y is determined in step #248.
ES), except for output form F (step #24
9), the process returns to the main flow shown in FIG.

On the other hand, when output format F is selected, since a predetermined number of images are captured within one screen, processing that is somewhat different from that for output formats A to F is performed. That is,
Every time an image is read out, the number of images is decremented from the output image number N (NO1 step #238).
247), and each time a predetermined number is reached (Y in step #238).
ES), multi-processing is performed (step #239),
After a predetermined number of multi-processed images are displayed on the TV monitor 57, they are printed or transmitted in units of a predetermined number of images as described above. At this time, the image valve at the time when the predetermined number of images has been reached is decremented in step #247 after step #246, so that the number N of output images can be accurately decremented. In addition,
In the case of output form F, if the number of output images N is not an integral multiple of the predetermined number of images, even if h = 0 in step #248,
Since there are remaining images (NO in step #238,
YES in step #248, NO in step #249)
, the processing from step #240 onward is also performed on the remaining images.

FIG. 25 shows an example of the table of contents displayed. When the memory card 26 is inserted into the playback device, the "Date and Time", "Time", and "Location" are displayed in the order of recording (or in the order of the photographed frame numbers) as shown in the figure.
Contents such as “Voice Cloth/None” and “Person’s Name” are displayed on the TV monitor 57.
will be displayed. Based on this table of contents display, it becomes easy to select the method for reproducing and displaying images or recording them in the filing device 61.

FIG. 26 shows an example of a screen for inputting search conditions for a search. The search conditions are ``Date and Time'', ``Time'', ``Place'', ``Speaker'', ``Weather'', and ``Others'', and in each condition column, as shown in the figure, ``Summer'' is set as ``Date'', and ``Summer'' is set as ``Time''. "Evening" is "Location" and "Flower Expo" is "
``Namba'' is input from the keyboard 62 as ``Speaker''. The CPU 50 executes the above-described search process based on the input search conditions. On the other hand, various operation instruction columns are prepared at the bottom of the screen, and can be specified by pointing the position with a tablet or mouse, for example.

FIG. 27 shows an example of the memory map of the memory card 26, which consists of a search information area, an image data area, an audio on/off and audio data area. Also,
This search information area contains the start address (■sta%ASta) and end address (■sta%ASta) for each of the above areas.
VendlAend) is also written. Recording in each area is performed in the order of image data, audio data, and search information according to instructions from the CPU 50.

Next, a case where each of the above-mentioned searches is performed using an inference function (fuzzy search) will be explained with reference to FIGS. 28 to 31.

With such reasoning, searches are performed based on membership functions. This membership function is stored in advance in the suitability storage means in a form corresponding to each search condition. Then, when a search condition is input, a membership function corresponding to the input search condition is selected, and a search is performed in descending order of suitability based on the selected membership function.

Now, Fig. 28 shows the length and size) search 1 for example r50
This shows a membership function when it is desired to reproduce something on the order of cmJ. “50±5cmJ is a conformity level of “1”
”, and r25cmJ and r75cmJ have a fitness of “0.5
”. Therefore, if you enter the search condition r50cmJ, based on this membership function, the results will be searched in order from those with a fitness of “1” to “0.9”, “0.8”, etc.
Priorities are assigned as follows, and those with [50±5 cmJ are extracted and reproduced first. Next, r44cmJ, r
56cmJ, continuation “4OCmJ, r60cmJ
The items with the highest degree of fitness are extracted in descending order, such as nearby items, and items near [35cmJ, r65cmJ, etc.
It will be played. In addition, if you enter the search condition rlookmj, r100±5cmJ is set to suitability "1", and r750mJ is set to suitability "0.5", for example.
As above, the items with the highest degree of fitness are extracted sequentially,
It will be played.

FIG. 29 shows membership functions when searching for a location, for example, when it is desired to play back a photograph taken in the "Kinki region." Therefore, if you enter "Kinki region",
Based on this membership function, first, the fitness is “1”.
Images shot in ``Osaka'' and ``Kyoto'' are extracted and played back.

Second, those taken in ``Hyogo'' and ``Nara,'' followed by ``Wakayama,''``Shiga,'' followed by ``Mie,''``Tokushima,'' and ``Okayama'' and ``Fukui,'' which have a high degree of relevance. Things will be extracted and reproduced in order.

Figure 30 shows seasonal searches, such as "spring,""summer," and "autumn."
, which shows each membership function when you want to play back images taken during each season of "winter." for example,"
If you want to play back images taken in ``Spring,'' first set the suitability to ``1.''
” photos taken in “April” and “May” are extracted,
will be played. Next, images taken in "June" will be extracted and played back. Furthermore, when it is desired to playback images taken in "summer", images taken in "July", "August", and "September" with a suitability of "1" are extracted and played back. Next, images taken in "June" will be extracted and played back. If you want to play back images taken in "autumn," images shot in "October" and "November" with a suitability of "1" are extracted and played back. Next, images taken in "September" will be extracted and played back. If you want to play back images taken in "winter", you can use "
Images taken in December, January, and February are extracted and played back. Next, images taken in "March" will be extracted and played back.

Note that the seasonal search is not limited to monthly units as described above, but may also be performed by date units. For example, priority may be given such that the degree of suitability for ``summer'' is 0.5 degrees, and the degree of suitability for ``autumn'' is 0.5 degrees for mid-September. In addition, the search may be performed from a broader perspective by taking other search conditions such as temperature and humidity into account.For example, when the search condition is "summer + hot",
A logical product is taken between those that satisfy the following and those that have a temperature of 30°C or higher. Similarly, when the search condition is "winter + hot", a logical AND is performed between those that satisfy the above-mentioned "winter" and those that have a temperature of 25° C. or higher.

Figure 31 shows the membership function when you want to play back images taken in each time period such as ``Morning'', ``-Noon'', ``Evening J, V Night J'' in the date and time search. .

If you enter U@ko, first enter "6 o'clock" with a suitability of "1".
The images taken between "9 o'clock" and "9 o'clock" are extracted and played back. Subsequently, the images taken in the order of 15:00, 10:00, and 4:00 are extracted and played back. If you enter "noon", first, "12 o'clock" to "14 o'clock" with fitness degree "1" are input.
The images taken during the period are extracted and played back. Subsequently, images taken at "11 o'clock" and "15 o'clock" are extracted and played back. When "evening" is input, first, images taken at "17:00" and "118:00" with suitability level "1" are extracted and played back. Subsequently, the image taken at 116 o'clock is extracted and played back. When "night" is input, first, images taken between 20:00 J and F3:00 J with a suitability of "1" are extracted and played back.Next,
Images taken at "7:00 p.m." and "4:00 p.m." are extracted and played back. Note that, as in the case of the seasonal search, search conditions such as temperature, humidity, etc. may be taken into consideration to perform a search from a broader perspective.

In addition to the above search examples, the barometric pressure sensor 19 and GP
It is also possible to search for images taken during mountain climbing from the altitude information provided by the S receiver 23. Further, by adding the focal length f and the second distance to the atmospheric pressure information and altitude information, it is possible to automatically input photographing information as an aerial photograph.

Further, the following can be considered as other determination methods at the time of search. That is, (1) Distinguish between men and women using voice recognition technology based on the difference in sound quality between men and women.

(2) Person identification is performed based on the color temperature and pattern recognition of the captured image of the WB sensor 14.

(3) Adults and children are distinguished from image magnification and pattern recognition.

(4) Determine whether or not glasses are worn by pattern recognition.

(5) The person in the image is memorized in advance, and the person in other images is discriminated using pattern recognition and a learning function.

In this embodiment, a digital memory is used as the recording medium, but an analog memory such as a floppy disk may also be used. Further, although the camera and the playback device are separate bodies, they may be integrated. Furthermore, the data obtained from each sensor may be displayed on the operation and display section 25 or on a separately provided display section.

In addition, although this example has been explained using an electronic still camera, each sensor is provided in a silver halide camera, and the photographic information of each of the above sensors is imprinted at the appropriate location within the photographic surface using a well-known date imprinting technique. You may also do so. In this case, the playback machine includes an optical reading section, a film drive section, a memory, a search processing section according to this embodiment, etc., and the film container is set in the optical reading section and the frames are sequentially or instructed. The photographed image and the imprinted photographic information may be read by COD or the like, extracted as an electrical signal, and recorded in the memory. Then, the same search process as described above is executed using the captured image and the captured information.

〔Effect of the invention〕

As explained above, according to the present invention, the positioning data of the photographing position is automatically recorded together with the photographed image by the GPS receiver, so that inputting the photographing place and recording operation can be performed later when searching for images. It is possible to provide an easy-to-use camera that is free from the conventional complexity of having to do it separately each time.
