The designated position data (latitude, longitude) is calculated based on the display map and the output position signal of the position indicating member 63. Alternatively, it may be detected by, for example, a tablet or the like. On the other hand, when the map display is not required, the place names and places recorded in association with the recorded image are read out and displayed, and a desired place name or the like is designated from the displayed place names or the like by inputting from the keyboard 62. Is performed (steps # 114 and # 115). continue,
CPU 50 searches for an image that matches the designated position or the input place name or the like (step # 116). This search is performed by scanning the search information recorded in association with each image. When the search is completed, the number of hits is displayed as the search result (step # 117).
At this time, the frame number of the corresponding image may be displayed. Thereafter, it is determined whether or not a re-search is necessary (step # 118). As an example of the re-search, a case where the number of hits is large or a case where it is zero may be considered. In the case of a re-search, if another search condition is input or specified, the search is performed by the CPU 50 in the same manner as described above (step # 111 to step # 117). When the search is completed (step # 1

In the flow of “date and time search” shown in FIG. 12, date information from the clock unit 24 is used as an index.

When the date and time, that is, the month, day, hour, minute, or season is input from the keyboard 62 (step # 121), the CPU 50 executes a search for an image that matches the input search condition (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 a storage unit that associates the season with the date and time data is provided in the CPU 50. If the search condition is a season, the input season is converted into the corresponding date and time data by the storage unit. A search is performed using the converted date and time data.

When the search is completed, the number of hits is displayed as the search result (step # 123). Note that the frame number of the corresponding image may be displayed as described above. Thereafter, it is determined whether or not a re-search is necessary (step # 124). In the case of a re-search, when another search condition is input, a search is performed by the CPU 50 in the same manner as described above (steps # 121 to # 123). When the search is completed (NO in step # 124), the process returns to step # 95.

In the flow of “weather search” shown in FIG. 13, temperature and humidity information from the temperature sensor 17 and the humidity sensor 18 are used as indexes.

When a state related to the weather, for example, “sunny”, “rain”, “hot”, “cold”, or the like is input from the keyboard 62 (step # 131), the CPU 50 searches for an image that matches the input search condition. This is performed by scanning the search information (step # 132). The CPU 50 is provided with storage means for storing in advance the correspondence between the above-mentioned weather-related state and weather data including temperature and humidity. For example, "hot"
Is input, the search may be performed based on a predetermined temperature and humidity, such as a temperature (temperature) of 30 ° C. or more and a humidity of 80% or more. Further, the reference temperature and the humidity may be changed depending on the place, date and time (also season). For example, if you want to search for “summer + hot”, the temperature should be 30 ° C or higher and July, August, September, while “winter + hot” should be 25 ° C or higher and 12,1, February thing. Then, at the time of retrieval, the input weather-related state is converted into corresponding weather data by the storage means, and a search is performed using the converted weather data.

When the search is completed, the number of hits is displayed as the search result (step # 133). Thereafter, it is determined whether or not a re-search is necessary (step # 134).

In the flow of “person name search” shown in FIG. 14, “speech” or “person name” is an index.

When "person name" is input from keyboard 62 (step # 141), CPU 50 executes a search for an image that matches the input search condition (step # 142). This process is performed in accordance with "search process I" shown in FIG. That is, first, it is determined whether the search is based on “voice” or “person name” (step # 151). For search by "voice", names entered is converted encoded in the personal name code, audio code corresponding to the person name code is extracted from the E ² PROM65 (step ♯153, ♯154). Next, audio data recorded in association with a pre-registered image is extracted from the filing device 61 and encoded (steps # 155 and # 156). Then, the voice code from E ² PROM 65 and the voice code from filing device 61 are collated (step # 157). This collation is performed for all the images by sequentially scanning the audio codes of the images registered in the filing device 61 (step # 1).

In the flow of “indoor / outdoor search” shown in FIG. 16, WB
The output from the sensor 14 serves as an index.

When either “indoor” or “outdoor” is selectively input from the keyboard 62 (step # 161), the CPU 50 searches for an image that matches the input search condition by scanning the search information. (Step # 162). In the CPU 50, the correspondence between the above search condition and the output (color temperature data) of the WB sensor, for example, for the color temperature data corresponding to under fluorescent light, "indoor", and the color temperature corresponding to under sunlight A storage means for storing data as "outdoors" is provided.
Then, at the time of retrieval, one of the input “indoor” and “outdoor” is converted into the corresponding color temperature data by the storage means,
A search is performed using the converted color temperature data.

When the search is completed, the number of hits is displayed as the search result (step # 163). Thereafter, it is determined whether or not a re-search is necessary (step # 164). In the case of a re-search, when other search conditions are input, a search by the CPU 50 is performed in the same manner as described above (steps # 161 to # 16).
3). When the search is completed (N in step # 164)
O), and return to step # 101.

In the flow of “person scenery search” shown in FIG. 17,
Information on “focal length f” and “subject distance D” (image magnification β
= FD) is the index.

First, either “person” or “landscape” is displayed on the keyboard 62.
(Step # 171), the CPU 50 searches for an image that matches the input search condition (step # 172). This process is performed in accordance with “search process II” shown in FIG. That is, first, all the focal length f and the subject distance D recorded corresponding to the images registered in advance in the filing device 61 are read out, and each image magnification β = f · D for all the images is calculated ( Step # 181). Subsequently, it is determined whether or not each of the obtained image magnifications β is β ≧ 1/100 (step # 182). If β ≧ 1/100, it is determined that the image is a landscape (step # 184). Is determined to be a person (step # 183). Then, 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 matching method, the determination may be performed for each image as described above, and the determination may be sequentially repeated. Upon completion of the determination for all the images, step # 173
Return to

Returning to FIG. 17, the number of hits and the like are displayed as the search result (step # 173). Thereafter, it is determined whether re-search is necessary (step # 174). In the case of a re-search, enter the other search condition and the CPU 50
(Step # 171 to Step # 17)
3). When the search is completed (N in step # 174)
O), and return to step # 103.

In the above embodiment, the association between the image magnification β and “person” or “landscape” is stored as a program.
A storage unit in which the image magnification β and “person” and “landscape” are stored in advance in the CPU 50 may be provided. As another search method, the image magnification β is obtained from the recorded focal length f and the subject distance D, and the range of the image magnification β for the input “person” and “landscape” is determined in advance. Alternatively, the search may be performed by determining in which range each image magnification β to be searched falls.

In the flow of “event search” shown in FIG.
The location code (event code) serves as an index.

When an event name is input from the keyboard 62 (step # 191), the CPU 50 scans an event code recorded in association with an image registered in advance in the filing device 61 for a search for an image matching the input search condition. (Step # 192). When the search is completed, the number of hits is displayed as the search result (step # 19).
3). Thereafter, it is determined whether or not a re-search is necessary (step # 194). In the case of a re-search, when another search condition is input, a search is performed by the CPU 50 in the same manner as described above (step # 191 to step # 193). When the search ends (NO in step # 194), the process returns to step # 105.

If the location code is a location identification code or a JIS code string of characters indicating information about the location, the code can be searched directly, and when shooting, the location code is recorded without discrimination. It is possible to do. In addition, since no special determining means for determining the content of the location code is required, the configuration on the search side can be simplified accordingly.

In the “voice search” flow shown in FIG. 20, the voice recorded in association with the image is compared with the voice input at the time of the search.

When a voice is input from the microphone of the voice input unit 64 (step # 201), the CPU 50 searches for an image matching the input voice (step # 192). This process is performed in accordance with the "search process III" shown in FIG. That is,
First, the input voice is A / D converted and coded,
The information is stored in a reference unit (not shown) (step # 211 to step # 213). Next, audio data recorded in association with a pre-registered image is extracted from the filing device 61 and encoded (steps # 214 and # 21).
Five). Then, the voice code from the reference unit and the voice code from filing device 61 are collated (step # 216). This collation is performed for all the images by sequentially scanning the audio codes of the images registered in the filing device 61 (steps # 215 to # 217).
NO, step # 218 loop). When the matching for all images is completed (YES in step # 217), step # 203
Return to

Returning to FIG. 20, the number of hits and the like are displayed as the search result (step # 203). Thereafter, it is determined whether or not a re-search is necessary (step # 204). In the case of re-search, enter another word by voice, and in the same way as above, CP
Search by U50 is performed (Step {201 to Step})
203). When the search is completed (N in step # 204)
O), and return to step # 107.

Next, returning to FIG. 9, the execution process of step # 86 will be described with reference to FIG.

In this execution mode, first, an output mode is selected. Table 1 shows this output form.

That is, after the search is completed, one output form is selected from the output forms A to F in Table 1 above, and
For example, when a corresponding character is inputted from step 62 (step # 221), the number of output images as a search result is set to N (step # 222), and subsequently, images to be output are filed in ascending order of frame number. The data is read from the device 61 and sequentially transferred to the frame memory 53 (step # 223). Next, an image is output according to the output mode selected in step # 221. When the output mode A is selected (step ♯)
The display is displayed on the TV monitor 57 as it is (YES in 224). When the output mode B is selected (YES in step # 225), data on 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 the subject distance D of the image, and The scale size is combined (steps # 226, # 227). That is, the scale size is superimposed on the image by the synthesizing unit 54 in a superimposed form,
Is output to

For example, when a unit scale is displayed (see FIG. 24 (B)), the scale size described on the unit scale SC is obtained by calculating the length per unit scale from the image magnification β calculated from the focal length f and the subject distance D. Is calculated. here,
The calculation of the length of the unit scale SC will be specifically described with reference to a principle diagram in an imaging state shown in FIG. In the figure, L is the shooting distance, the distance from the subject 100 to the imaging surface 200, f is the focal length of the shooting lens 300, H is the distance between the principal points of the shooting lens 300, and x is the distance from the subject 100 to the shooting lens 300.
, X ′ is the distance from the imaging surface 200 to the back focus of the taking lens 300, y is the length of the subject 100, and y ′ is the length of the image of the subject 100 on the imaging surface 200. , Y: y '= x: f = f: x' between the variables L, f, H, x, x ', y and y' (1) x '= L-2f-H −x (2) From the equations (1) and (2), the equation x ² − (L−2f−H) x + f ² = 0− (3) is established. When the root of this equation (3) is obtained, Further, using the above equation (2), Becomes From the above equation (1), y = y ′ · x / f (6) y = y ′ · f / x ′ (7) By performing the calculation of the expression (6) or (7) based on x and x ', the length y of the subject corresponding to the length y' of the image on the imaging surface is obtained.
Here, when the length y 'of the image on the imaging surface is treated as the length of the unit scale SC, the actual length (on the imaging surface) of the unit scale is known in advance, and therefore, (6)
The scale size of the unit scale SC is obtained by the operation of the expression or the expression (7).

 FIG. 24 shows a display example of the scale size.

FIG. 7A is a display example when the image magnification is displayed as it is, and FIG. 8B is a display example when the unit scale SC is equivalent to 10 cm.

The display of the scale size makes it easy to grasp the actual size of the image. In addition, the display timing of the scale SC can be freely changed by the read clock generator 59 controlled by the CPU 50, so that the scale SC can be moved to a desired position, for example, by a trackball (position specifying member 63). If it can be performed, the operability will be excellent. Further, it is easy to switch on and off the scale display, and the display modes shown in FIGS. 3A and 3B may be freely switched.

Incidentally, using the technology described in JP-A-58-158507,
By displaying the scale on a silver halide film, the display of the scale size can be applied to a silver halide film.

Next, when the output mode C is selected (step # 228
YES), display screen size (eg CRT inch etc.)
Is input from the keyboard 62 (step # 229). Subsequently, the image size is changed based on the image magnification obtained from the focal length f and the subject distance D and the display screen size (step # 230). That is, in order to display the display magnification (image size) of the size of the image finally displayed on the TV monitor 57 with respect to the actual size of the subject, or to fix the display magnification to a predetermined size regardless of the display screen size. The size of the display image is changed and displayed.

That is, the CPU 50 has display magnification calculating means for obtaining a display magnification of a reproduced image from the image magnification obtained from the focal length f and the object distance D and the display screen size. For the size of
The size of the image displayed on the TV monitor 57 is determined. If the display magnification is set in advance, a ratio between the display magnification calculated by the display magnification calculation means and the set magnification is obtained, and the displayed image is enlarged or reduced according to the ratio. Image processing is performed for this purpose. In the above, the final display magnification is displayed at an appropriate position on the TV monitor 57 as necessary.

This makes it easy to grasp the actual size of the image displayed on the TV monitor 57.

Next, when the output form D is selected (step # 231
YES), an image to be combined and displayed is extracted by the item search shown in FIG. 10 (step # 232). Then, a desired image is selected from the images that match the search condition (step # 233). Subsequently, the image magnification of the previously selected image, the image magnification of the subsequently selected image, and both displayed images are guided to the special reproduction processing unit 52, where, for example, a specific subject in both images is displayed. The image size is appropriately changed so as to be the same size, written into the image frame memory 53,
Output to the TV monitor 57 (step # 234). By doing so, the size of the subject 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 the two images displayed side by side are matched, the actual size of the subject in both images can be easily compared. Further, as in the case of the scale display, by moving (superimposing) both display images with a trackball (position specifying member 63) or the like, a composite photograph or the like can be enjoyed.

It is to be noted that the current photographed image and the previously photographed image are combined by using both image magnifications, and for example, it is also possible to reproduce a head-cut photograph or the like as a completed photograph.

Next, when the output mode E is selected (step # 235
YES), the displayed image is guided to the special reproduction processing unit 52, where the display image is subjected to various special processing such as mosaic, negative / positive inversion, and then output to the TV monitor 57 ( Step # 236).

Next, when the output mode F is selected (step # 235
NO), a predetermined number of images such as four, nine or sixteen are reproduced on one screen. The predetermined number may be selected in advance or as necessary, or a desired number such as (2 × 3) may be selected.

First, the frame number and the number of images of the image desired to be multi-reproduced are stored (step # 237). Next, it is determined whether or not the number of images has reached the predetermined number (step # 1).
238) If the number is the predetermined number, multi-processing is performed (step # 239), and the routine goes to step # 240. On the other hand, if it is not the predetermined number, the process moves to step # 247. The details of the processing in the case of the output mode F will be described later.

Now, when one of the output modes A to F is selected and an image obtained under the selection is displayed on the TV monitor 57 (step # 240), next, is it determined whether or not sound is recorded for the displayed image? It is determined whether or not it is (step # 241). If the sound is recorded, the sound corresponding to the displayed image is reproduced (step # 242). Subsequently, it is determined whether the display image is to be printed or not (steps # 243 and # 245). When you give a print instruction,
The display image is printed out by the printer 71,
When the transmission instruction is given, the display image is transmitted using the FAX 72, the videophone 73, or the like (steps # 244, # 246).

When the printing or transmission of one sheet is completed, the number N of output images set in step # 221 is decremented by 1 (except when the output form F is selected).
Subsequently, it is determined whether or not the output image number N is 0 (step # 248). If N = 0, the process returns to step # 221, where the next image is displayed. After the displayed image is printed or transmitted, the value of N is decremented (step # 221).
221 to step # 247). Such processing is repeated for the number of output images, and when N = 0 (step # 248)
YES), except in the case of the output form F (step # 249
YES), returning to the main flow of FIG.

On the other hand, when the output mode F is selected, a predetermined number of images are taken in one screen, so that processing slightly different from that of the output modes A to F is performed. That is, each time an image is read, the number of images is decremented from the number N of output images (NO in step # 238, NO in step # 2).
47) Every time the number reaches a predetermined number (YES in step # 238), multi-processing is performed (step # 239). After the multi-processed predetermined number of images are displayed on the TV monitor 57, the images are printed or transmitted in a predetermined number of units in the same manner as described above. At this time, the image at the time when the predetermined number has been reached is decremented in step # 247 after step # 246, so that the accurate decrement processing of the number N of output images is performed. In the case of the output mode F, if the number N of output images is not an integral multiple of the predetermined number, even if N = 0 in step # 248, there are remaining images (NO in step # 238, NO (YES in # 248, NO in step # 249), and step # 240 for the remaining images
The following processing is performed.

FIG. 25 shows a display example of the table of contents. When the memory card 26 is inserted in the playback device, as shown in FIG. The contents such as “with / without voice” and “person name” are displayed on the TV monitor 57. Based on this table of contents display, reproduction and display of an image or selection of a recording method for the filing device 61 can be easily performed.

FIG. 26 shows an example of a screen for inputting search conditions at the time of search. Search conditions include "date and time", "time" and "location"
"Speaker", "Weather" and "Other" are prepared, and "Summer" as "Date", "Evening" as "Time", and "Hanahiro" as "Place" are shown in each condition column as shown in the figure. "Namba" is input from the keyboard 62 as the "speaker". CPU5
“0” executes the above-described search processing based on the input search condition. On the other hand, various operation instruction columns are prepared at the bottom of the screen, and the designation can be performed by, for example, indicating the position with a tablet or a mouse.

FIG. 27 shows an example of a memory map of the memory card 26, which includes a search information area, an image data area, an audio on / off, and an audio data area. The search information area includes a start address (Vsta, Asta) and an end address (Vend, Aen) for each of the above areas.
d) is also written. Recording in each area is performed in the order of image data, audio data, and search information in accordance with an instruction from the CPU 50.

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

With such inference, the search is performed based on the membership function. This membership function is stored in advance in the matching degree storage means in a form corresponding to each search condition. 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 relevance based on the selected membership function.

By the way, FIG. 28 shows a length (size) search, for example, "50c
It shows the membership function when you want to play back something like "m". "50 ± 50cm" is the degree of conformity "1",
“25cm” and “75cm” have a conformity of “0.5”. Therefore, when a search condition of “50 cm” is input, priorities are assigned based on this membership function, such as “0.9”, “0.8”,. Those of "50 ± 50cm" are extracted and reproduced. next,
"44cm", "56cm", followed by "40cm", "60cm"
Those that are closer to each other, such as those near “35 cm” and “65 cm”, are extracted and reproduced in order from the one with the highest matching degree. When a search condition of “100 cm” is input, “100 ± 50 cm” is set as the matching degree “1”, and “75 cm” is set as the matching degree “0.5”. Will be played.

FIG. 29 shows a membership function when a search for a place, for example, a picture taken in the "Kinki region" is to be reproduced. Therefore, if you enter "Kinki region",
Based on this membership function, the ones that were shot at “Osaka” and “Kyoto” with a fitness level of “1” are first extracted,
Will be played. Next, those shot in "Hyogo" and "Nara", as well as "Wakayama" and "Shiga", followed by "Mie", "Tokushima", "Okayama" and "Fukui" It is extracted and reproduced in order from the object.

FIG. 30 shows a seasonal search such as "spring", "summer",
It shows each membership function in the case of not reproducing what was photographed in each season of "autumn" and "winter". For example, when it is desired to play back images shot in "spring", first, images shot in "April" and "May" with a matching degree of "1" are extracted and played. Next, the image taken in "June" is extracted and reproduced. If the user wants to play back images taken in “summer”, “July” and “8
Those photographed in “Month” and “September” are extracted and reproduced. Next, the image taken in "June" is extracted and reproduced. If the user wants to play back what was shot in "Autumn", those shot in "October" and "November" with a matching degree of "1" are extracted and played. Next, the image taken in "September" is extracted and reproduced. If you want to play back what was shot in "Winter", select "12"
Those photographed in "Month", "January" and "February" are extracted and reproduced. Next, the image taken in “March” is extracted and reproduced.

It should be noted that the seasonal search is not limited to the month unit as described above, but may be performed on a date unit. For example, priorities may be assigned to “mid-September” such as “0.5” in the case of “summer” and “0.5” in the case of “autumn”. Further, a search from a wider viewpoint may be performed in consideration of other search conditions such as temperature and humidity. For example,
When the search condition is “summer + hot”, the logical product of the item satisfying the above “summer” and the item satisfying the temperature of 30 ° C. or more is calculated.
Similarly, when the search condition is “winter + hot”, a logical product of a product satisfying the “winter” and a product having a temperature of 25 ° C. or higher is obtained.

FIG. 31 shows a membership function in a case where it is desired to reproduce a picture taken in each time zone such as “morning”, “day”, “evening”, and “night” in the date and time search.

If "morning" is entered, first "6 o'clock" with a fitness of "1"
To 9 o'clock are extracted and reproduced. Subsequently, those shot in the order of "5 o'clock", "10 o'clock", "4 o'clock" are extracted and reproduced. When "noon" is input, first, images captured between "12:00" and "14:00" of the fitness level "1" are extracted and reproduced. continue,
Those shot at "11:00" and "15:00" are extracted and reproduced. When "evening" is input, first, images captured at "17:00" and "18:00" with the fitness level "1" are extracted and reproduced. Subsequently, the one photographed at "16:00" is extracted and reproduced. When "night" is input, first, images captured between "20:00" and "3 o'clock" with a matching degree of "1" are extracted and reproduced. Subsequently, those shot at "19:00" and "4 o'clock" are extracted and reproduced. As in the case of the seasonal search, the search may be performed from a broader viewpoint in consideration of other search conditions such as temperature and humidity.

In addition to the above search examples, the barometric pressure sensor 19 and the GPS
The receiver 23 can also search for images taken during mountain climbing from altitude information. Furthermore, when the focal length F and the photographing distance D are added to the atmospheric pressure information and the altitude information, photographing information as an aerial photograph can be automatically input.

Further, the following can be considered as another determination method at the time of search. That is, (1) gender discrimination is performed on the difference in sound quality between men and women using voice recognition technology.

(2) A person is identified from the color temperature and the pattern recognition of the captured image by the WB sensor 14.

(3) An adult or child is determined from the image magnification and the pattern recognition.

(4) The presence or absence of glasses is determined by pattern recognition.

(5) A person in an image is remembered in advance, and a person in another image is determined using a pattern recognition and a learning function.

In the present embodiment, a digital memory has been described as a recording medium, but an analog memory such as a floppy disk may be used. Also, the camera and the player are separate, but
