Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a camera capable of recording temperature data.

[Conventional technology]

Conventionally, when taking photos with a silver halide camera, the date and time of the photo taken,
A system has been proposed in which aperture value AV, shutter speed TV, etc. are recorded as photographic information for each frame in a semiconductor memory built into a film container in association with the photographed image (Japanese Patent Laid-Open No. 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], the image stored in the memory card obtained in this way is processed using the 7-filling system (DA).
There is also a known system in which information is transferred to T), and search information is manually added at the time of transfer to facilitate subsequent searches using a personal computer or the like.

Note that a camera is provided that is provided with a temperature sensor to perform temperature compensation for a solid-state imaging device (COD).

[Problem to be solved by the invention]

In the camera described in JP-A-1-289948,
Date obtained at the time of shooting, aperture value AV, shutter speed TV
is not used as search information during image search, and no configuration for that purpose is shown. Similarly, the temperature sensor provided for temperature compensation does not use temperature data as search information, and therefore there is no configuration to record it in association with a photographed image.

Furthermore, even with devices that allow captured images to be stored on a memory card, the user must manually enter data for search information each time they are transferred to a filing system, which is not always convenient. I can't say it's enough.

The present invention has been made in view of the above, and an object of the present invention is to provide a camera that records temperature data obtained by a temperature sensor as temperature (air temperature) information at the time of photographing together with a photographed image.

[l! Means to solve the problem]

The present invention provides a camera that records photographed images, including a temperature sensor, a recording means for recording temperature data obtained from the temperature sensor, and recording the temperature data in the recording means in correspondence with the photographed image. It is equipped with 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, temperature (air temperature) information obtained by the temperature sensor 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.

2 is an image sensor (
Under LX (referred to as COD), a subject image obtained through the lens 1 is captured. The amplifier 3 amplifies the output image signal from the CCD 2 at a predetermined amplification factor and outputs it to the next stage AD converter 4.

The AD converter 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.
Output the signal to memory card I/F9.

The microphone 10 to the memory 13 are configured for audio 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 1o at 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 for voice recording (speaker W
11E), which temporarily stores the input digital audio data and then outputs it to the memory card I/F 9.

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 light receiving sections are input to the AFCPtJ16, and the AFCPU16 calculates the phase difference from the subject images of the 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 measure the temperature (air temperature), humidity, and atmospheric pressure, respectively, during imaging. Each measured data is processed by CPU20
Output to. Each of the above-mentioned sensors automatically measures each data during imaging and guides it to the CPLJ 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 receives a code related to the location where it is received through the antenna 21a.
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 converts the received FM signals into II! By doing so, the location code data is reproduced and output to the CPU 20.

Note that details will be explained with reference to FIG. 2. On the other hand, GPS receiver 2
3 receives radio waves from 11T1 (not shown) with the antenna 23a, calculates the latitude, longitude, and altitude of the current position, and sends it to the CPU 2.
The details are 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 composed of the CPtJ 20 and an operation and display section 25 that outputs the operation status of each operation switch 81 to S3 to the CPIJ 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 photography 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 unit 25 outputs the switching states of the switches 81 to S3 to the CPU 20, and displays various types of information such as frame numbers from the CPU 20 at the time of photographing, if necessary.

Furthermore, the memory card I/F 9 stores the image data, audio data, and various photographic information under the control of the CPU 20 as an SRAM or E2 PROM that can be inserted into and removed from the camera body.
The usage status of the memory card 26 (presence or absence of a storage area, etc.) is output to the CPU 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.
Figure (A) shows a transmitter that is installed in each region, tourist spot, event venue, etc. and transmits a location code.
) 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 shift 11 (DPSK) is applied to the carrier wave by the output code data from OM201.
Phase 5-hift key ng) is applied. The FM modulation section 203 applies FMIII to the carrier wave according to the input serial data, and further applies the FM III 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'&11 section 202 and the FM
A clock pulse GK is output to the modulation section 203.

Note that the DPSK modulation is performed by the timing generation circuit 20.
Phase difference data is extracted from digital data by AFM in the audible range, MFM in medium waves, PLL method, etc. using clock pulse GK of 6, and converted into serial data.

Next, in FIG. . The received signal is F
M4! The carrier frequency is removed in the coding section 208, and the signal is 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
The PtJ 20 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 2 according to a control signal from the CPU 20.
Clock pulse GK is output at 09.

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 receives transmitted radio waves from a NAVASTAR satellite (not shown), for example, to a quadrifiller! J'／
It is of the OLI adrifilar heX type. RF signal mixer 2 received by this antenna 23a
30 is input. On the other hand, the modulator 231 is the local oscillator 2
The local oscillation signal CK1 from 32 is sent to the PN code generator 23.
The spread modulated signal is input to the mixer 230. As a result, the IF signal, which is the intermediate frequency of the RF multiplied signal, is converted into an IF low signal and input 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 is always set to PN by the clock pulse CK2 from the PN code output 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 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. During the delay FR of this PN code, the measurement clock generator 23
The counted value is output from the delay measurement 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. From the reception time data obtained from a cesium and rubidium vapor atomic clock (not shown), calculate the radio wave propagation time from the satellite to the GPS receiver (camera), and use the time to calculate the distance from the satellite to the GPS receiver (camera). calculate. Then, the data processing circuit 235 uses the distance information from each satellite and the position information of each satellite itself included in the demodulated data to
The positional information regarding the latitude, longitude, and 6 degrees of is calculated and output to the CPU 20.

As is well known, GPS is a system that covers the entire world using eight NAVASTARs, but currently not all satellites have been launched, and there are areas where reception is not possible or where reception is unavailable depending on the time of day. The CPU 20 enables automatic storage of the location code data from the location code receiver in such areas where reception is not possible.On the other hand, when no location code transmitter is installed and no location code is received,
Both receivers are controlled so that they receive data from the satellite, take in the received data as position information, and interpolate with 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 taking pictures and the process returns to step #1; if it is on (YES in step #9), the process moves to step #10. In other words, 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 the temperature, and the humidity sensor 18 measures the temperature. Humidity measurement, atmospheric pressure measurement by the atmospheric pressure sensor 19, positioning by the GPS receiver 23, and reception of FM radio waves including the location code by the location code receivers 21 and 22 are performed in sequence (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 proceeds to step #18, and the state of switch S1 is checked again.

Here, if switch S1 is on (step #18
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 (NO in step #18). , 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, the audio input selector switch S3 is turned on.
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 recognition, for example, one second of audio is captured (step #28).

After the above operations, image data, audio data, and search information (photographing information) obtained from each sensor, etc. are written in the memory card 26 in a corresponding form (see FIG. 27) (step #29), and The space information on the card 26 is updated and the frame number is counted up by 1 (
Step #30° Step #31), prepare for the next shooting.

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 amplifier 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 read clock generation circuit 59 supplies clock pulses for read timing to the image frame memory 53, the synthesis section 54, the DA converter 55, and the superimpose memory 58, respectively.

The character generator 60 stores character fonts of Japanese Industrial Standard JIS code strings, and outputs the corresponding character code to the CPU 50 when a JIS code string is adopted as the location code. The filing device [61] is a so-called album, which is composed of a recording medium such as an optical disk and a driving circuit thereof, and records the recorded images in the memory card 26 as appropriate. This filing device 6
1 is controlled by the CPU 50 for reading and writing, and images;
It records the registration search information and outputs the 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.
, through an amplifier 68, and is led to a subiki force 69, where the audio is reproduced. The speaker recognition unit 70 recognizes the voice data input via the memory card I/F 51 and the E2PROM for the speaker data.
65 to determine whose voice it is. The judgment result for this speaker is CPU
It is also output to 50 and used as an index at the time of 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 image that has been read out is subjected to reproduction processing for multi-screen use in the special reproduction processing section 52, and then
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 CPLI 50 accepts the selection of an image desired to be registered in the filing device 61 from among the images in the multi-screen, and then the frame number of the corresponding image is input using the keyboard 62 etc. to make the selection. 44), multi-image display is performed again for the selected image (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)
o> By performing a registration operation with the keyboard 62, the image and search information are recorded in the filing device 61, and the recorded image and search information are erased from the memory card 26 (step #47, Step #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 other images are asked whether or not correction, etc. is necessary (from step #51 to step #4).
(Return to 6). 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'' in which voices are registered in association with a person's name, and FIG. 8 shows the procedure of ``Voice Registration ■'' in which only voices are registered. This amphipod is in step #51 above.
It may be executed in , or it 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.
transformed 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) 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 speaker's name 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 the C image selection for the multi-screen to be updated is completed (YES in steps #83 and #84), the selected image is output in the desired output format as described later (step #86). ).

FIG. 10 shows a flowchart of "item search" for the search items shown in step #81.

In this example, the search items are "location", "date and time".
Examples include ``weather,''``people'snames,'' ``indoors and outdoors,''``portraits,''``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, the user is then asked whether or not to select "weather" as a search item (Stella 7 #95).
. When "weather J" 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 "person's name" is selected, the flow of "person's name search" shown in FIG. 14 is executed (step #98). If it is not selected, then an inquiry is made as to whether or not to select "indoor/outdoor" as a search item (step #99).If "indoor/outdoor" is selected, "indoor/outdoor search" shown in FIG. 16 is performed. The flow is executed (step #100). If not selected,
Next, an inquiry is made as to whether "portrait scenery" should be selected as a search item (step #101). When "portrait scenery" is selected, the flow of "portrait 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 Co." as a search item (step a103).
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” 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). After this, the "item search j 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 J" shown in FIG. 11, the location code and/or the GPSi 1st rank 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 map stored in the built-in memory (not shown) of the CPLJ 50 or the removable map-dedicated memory (also not shown) is guided to the TV monitor 57 and displayed (step #112), and the position of the mouse, etc. is indicated. The member 63 specifies the position on the displayed map (step #113
). The indicated position data (tlI degrees, longitude) is calculated based on the displayed map and the output position signal of the position indicating 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. (Steps #114 and #115). Subsequently, the CPL 150 searches for an image that matches 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. If you want to re-search, enter or specify other search conditions, and then click CP in the same way as above.
A search is performed by U50 (steps #111 to #117). Then, when the search is completed, if the answer is NO in step #118, the process returns 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), the C
The PU 50 searches 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. In addition, CPU50
There is a storage means in which the season and date and time data are associated with each other, and when the search condition is season, the input season is converted into the corresponding date and time data in the storage means, and the converted Search is performed using 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), 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 "sign", the temperature will be 3.
The search may be performed based on a certain predetermined temperature and humidity, such as a temperature of 0° C. or higher or a humidity of 80% or higher. Furthermore, the reference temperature and humidity are based on the location, date and time (season as well).
It may be changed by For example, if you want to search for "summer + hot", the temperature is 30'C or higher, and
．． For August and September, on the other hand, for "winter + hot", the temperature should be 25 degrees Celsius or higher, and 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 etc. are displayed as the search results (step #133). Thereafter, it is 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 the "person's name" is input from the keyboard 62 (step #141), the CPU 50 searches for images that match 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). “Sound 2
In the case of a search using "voice," 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 E2 PROM 65 (steps #153 and #154). Next, audio data recorded in association with images registered in advance is extracted from the filing device 61 and encoded (step #
155, #156).

Then, the audio code from the E2 PROM 65 and the audio code from the filing device 61 are compared (
Step #157). This verification is done by the filing device 61.
This is performed for all images by sequentially scanning the audio codes of the images registered in the image (step #156 to step #158, NO1 step #159 loop).

When the matching for all images is completed (YES in step #158), the process returns to step #143. On the other hand, if the search by person's name is selected in step #151, the search is performed by scanning the person's name code input at the time of image registration to the filing device 161 (step #152), and when the search is completed, step #143 Return to.

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 U50 (steps #141 to #143).

Then, when the search is completed (No at 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 "indoor" or "outdoor" 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
In the PU 50, there is a correspondence relationship between the above search conditions and the output of the WB sensor (color temperature data), for example, "indoor" for color temperature data corresponding to fluorescent lighting, and color temperature data corresponding to sunlight. A storage means is provided for storing the information as "outdoors". When searching, one of the input "indoors" and "outdoors" is converted into corresponding color temperature data in the storage means, and the 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 the CPU
50 is performed (step #161 to step #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,
Information on “focal length f” and “subject distance D” (image magnification β
-f-D) becomes the index.

First, select either "person" or "landscape" on the keyboard 62.
When input from step #171), a search within the CPU 50 is executed (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 the entire image is calculated. (Step #181). Next, it is determined whether the obtained image magnification β is 1/100 above β (step #182), and if it is 1/100 above β, it is determined that the image is a landscape (step #184), and vice versa. If so, it is determined that the person is a person (step #183). Then, the CPU 50 extracts the result of step #183 when "person" is input as a search condition, and extracts the result of step #184 when "landscape" is input as a search condition.

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 ends (NO in step #174), the process returns to step #103.

In addition, in the above embodiment, the image magnification β, "person", "landscape"
Although the association is stored as a program, a storage means may be provided in the CPU 50 in which the image magnification β and "person" and "landscape" are stored in association with each other in advance. In addition, as another search method, the image magnification β is calculated from the recorded focal length f and subject distance;
The search may be performed by predetermining ranges of image magnifications β for "people" and "landscapes" and determining which range includes each image magnification β to be searched.

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 CPU 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. (Step #192). When the search is completed, the number of matching items etc. 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-search, if other search conditions are input, the search by the CPU 50 is performed in the same manner as above (steps #191 to #1).
93). Then, the search ends (step #194).
(No), the process returns to step #105.

In addition, if the location code is a JIs code string of characters that display information about the location or the identification code of the location, it will be possible to search directly using the code, and when shooting, the content of the location code will be used as it is without being determined. It becomes possible to record. 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 CPU 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, encoded, and then stored in a reference section (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 (
Loop of step #215 to step #217 with NO1 step #218). 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 above search result (Step #203>. After this, it is determined whether a re-search is necessary (Step #204). In the case of a re-search, it is determined whether the re-search is necessary or not. When a word is input, a search is performed by the CPU 50 in the same manner as above (step 201).
~Step #203). Then, 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 the 22nd bowl.

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

(Hereinafter, blank space) Table 1 In other words, after the search is completed, one output form is selected from the output forms A to F of the clothing 1, and the keyboard 6
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 #22
3). Next, the image is output according to the output format selected in step #221. If output format A is selected (
YES in step #224), then TV monitor 5.
7 is displayed. If output format B is selected (YES in step #225), the data regarding the size of the subject on the imaging plane and the scale size are determined from the information about the focal length f and subject distance of the image. , the image and the scale size are combined (steps #226, #227
).

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 Fig. 24 (B)), the scale size marked on the unit scale SC is the length per unit scale from the image magnification β calculated from the focal length f and 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 taking lens 300, H is the principal point spacing of the taking lens 300, X is the distance from the subject 100 to the front focal point of the taking lens 300, and X- is the imaging surface 20.
0 to the rear focus of the photographing lens 3°, y is the length of the subject 100, and y' is the distance of the subject 1 at the imaging plane 200.
00 image length, and each of the above variables 11f, @, x, x
Between ySy-, V:V =x:f-f:x-...(1)x
=1-2f-H-x -=·(2). From these equations (1) and (2),
The equation 2f-H) ...... (4) Furthermore, using the above formula (2), X--((L-2f-H)-L-2f-H) -4f )/2 ... ) becomes. Also, from the above formula (1), y−y−・X/f ・・・・・・(
6) y=y -f/x-... (7) Therefore, based on x and x' in equations (4) and (5) above, this equation (6) or (7) By performing the calculation, the length y of the subject corresponding to the length y- of the image on the imaging surface can be found. Here, the length y- of the image on the imaging surface is defined as the unit scale SC
Since the actual length of this unit scale (on the imaging plane) is known in advance, the scale size of the unit scale SC can be found by calculating equation (6) or (7) above. .

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 it is shown that the unit scale SC corresponds to iocm.

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. 8A and 8 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), the size of the display screen (for example, CRT inches, etc.) is input from the keyboard 62 (step #
229). 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. A display magnification of the size of the displayed image ((image size)) is displayed, or the size of the displayed 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 determines the focal length f and the subject distance 111.
The display magnification calculation means calculates the display magnification of the reproduced image from the image magnification obtained from tD and the display screen size, and the display magnification calculation means calculates the display magnification of the reproduced image based on the image magnification determined from tD and the display screen size. The size of the image 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 as necessary.

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 combination 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 to be displayed together are led to the special reproduction processing section 52, where:
For example, the image size is changed as appropriate so that a specific object in both images is the same size, and the image size is written into the image frame memory 53 and output to the TV monitor 57 (step #23).
4). 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. or,
Conversely, 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 a previously taken photo by using both image 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 guided 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
rNO>, 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 (2x3) 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 has reached the predetermined number, multi-processing is performed (step #239>, step #24).
Transition to 0. On the other hand, if the number of sheets is not the predetermined number, step #
247. Note that details of the processing in the case of output form F will be described later.

Now, when any 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), the next step is to determine whether or not audio is recorded for the displayed image. A determination is made as to whether
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, #246).

When printing or transmission of one sheet is completed, the number of output images N set in step #221 is decremented by 1 (except when output type BF is selected),
Subsequently, it is determined whether the number N of output images is 0 (step 9248).

If it is not N-0, the process returns to step #221, the next image is displayed, and after the displayed image is printed or transmitted,
The count of N is decremented (step #221 to step #247>. This process is repeated for the number of output images, and after this, when N=0 (step #248, Y
ES), except for output form F (step #249
(YES), 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, by decrementing the number of images when the predetermined number has been reached in step #247 after step #246, the number N of output images can be accurately decremented. In addition,
In the case of output type flF, if the number of output images N is not an integral multiple of the predetermined number, even if N=O in step #248, there are remaining images (No in step #238).
, Step #248rYES, Stella 7 #249 (No), Step #240 for the remaining images
Subsequent processing is performed.

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 “audio presence/absence” 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 1 date and time, [time], ``location,''``speaker,''``weather,'' and ``other.'' 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 "Location".
"Namba" is input from the keyboard 62 as "Speaker". The CPLJ 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/A), and an audio data area. Also,
This search information area contains the start address (Vsta, ASta) and end address (Vend) for each of the above areas.

Aend) is also written. Recording in each area is C.
Image data, audio data, and search information are searched in this order according to instructions from the PU 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, Figure 28 shows the length and size) search, for example r50.
This shows a membership function when it is desired to reproduce something on the order of cmJ. [50±5cmJ has a fitness level of “1”
'', and r25cmJ and r75CmJ are the goodness of fit ``0''.
．． Therefore, when the search condition r50cmJ is input, based on this membership function, the fitness is 0.9'', 0.8'', and
The order of priority is given as follows: [50±5cmJ
are extracted and reproduced. Next, r44cmJ,
r56cmJ, followed by “4QcmJ, r60cm
The values are extracted and reproduced in descending order of suitability, such as those near J, then those near [35 cmJ, r65 cmJ, etc. In addition, if you enter the search condition rloOcmJ, it will be displayed as "100±50mJ has a suitability of "1", and for example, r750mJ has a suitability of "0.5".
”, and as above, those with the highest degree of suitability are sequentially extracted and reproduced.

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 J. 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.

Next are those taken in "Hyogo" and "Nara", followed by "Wakayama", "Shiga J", followed by "Miezu, F Tokushima", then "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 a photo 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 shot in "summer", images shot in "July", "18th", and "September" with a suitability of "1" are extracted and played back. Next, images taken in "June" will be extracted and played back. When it is desired to playback images shot 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,""
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, for "mid-September," the suitability for "summer" may be "0°5," and the suitability for "autumn" may be "0.5." The search may be performed from a broader perspective by taking other search conditions such as temperature and humidity into consideration.For example, when the search condition is "summer + hot", the above-mentioned "summer"
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 "morning", "noon", and "evening" in the date and time search.
This shows the membership function when it is desired to play back images taken in each time period such as "F night," and so on.

If you enter "morning", first "6 o'clock" with a fitness of "1" is input.
The images taken between "9 o'clock" and "9 o'clock" are extracted and played back. Subsequently, the images taken in the order of "5 o'clock" and rlORJ "4 o'clock" are extracted and played back. If you enter "noon", firstly, "12:00" to "14:00" with fitness level "1".
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 o'clock" and "118 o'clock" with a suitability of 01'' 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 120:00 and "3:00" with a suitability of "1" are extracted and played back. Next, “1
Images taken at 9 o'clock and 4 o'clock are extracted and played back. Note that, as in the case of the seasonal search, search conditions such as temperature and humidity 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 FJi 23. Furthermore, by adding the focal length f and illumination 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 the presence or absence of IM 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.

Furthermore, although this embodiment has been explained using an electronic still camera, each sensor is provided in a silver halide camera, and the photographing information of each of the above sensors is imprinted at an appropriate location within the photographic screen using a well-known date imprinting technique. Good too. In this case, the playback machine includes an optical reading section, a film drive section, a memory, a search processing section according to the present embodiment, etc., and inserts the film container into the optical reading section and prints out the frames sequentially or as 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.

(Effects of the Invention) As explained above, according to the present invention, temperature information at the time of photographing is automatically recorded together with the photographed image by the temperature sensor. It is possible to provide an easy-to-use camera that is free from the conventional complexity of having to input and record temperature separately each time.
