Description

  The present invention relates to an imaging apparatus that captures an image of a subject (hereinafter referred to as an image to be captured) and stores the captured image in a storage medium, and more particularly to an imaging apparatus having an image search function.

  An image pickup apparatus that picks up an image to be picked up and stores it in a storage medium has been put into practical use. However, as the capacity of the storage medium increases, it is desired that the stored image can be easily searched.

In response to this demand, according to Patent Document 1, the feature amount of the image data stored in the storage medium and the feature amount of the search key image data are extracted, and the desired image data is obtained by comparing the two. An image pickup apparatus for searching and extracting has been proposed.
JP 2000-76302 A.

  However, the image search means disclosed in the above document does not sufficiently consider the user-friendliness in terms of the imaging of the search key image, the setting, the search key image management method, etc., and there is room for improvement. There were many.

  For example, it would be preferable for the user to be able to clearly distinguish between the operations when capturing normal image data and when capturing search key image data without breaking the consistency of operations.

  By the way, in an imaging device that captures normal image data and search key image data without distinction and saves them in a storage medium, if a large number of image data is stored in the storage medium, an operation of selecting search key image data is required. It will be troublesome. In particular, in the future, it is expected that the capacity of the storage medium will increase rapidly and the number of image data stored in the storage medium will be enormous, so it will be more difficult than ever to find the search key image data. It will be.

  Therefore, if the normal image data and the search key image data are separated and stored from the imaging stage, the setting operation of the search key image data in the subsequent image search will be easier.

Accordingly, the present invention aims to solve at least one of such problems and other problems. For example, while searching for an image based on a captured image, it is possible to capture another image, and when a search process based on another search key image is being performed, the search key image is captured based on that image. An object is to reduce the load of the search process by controlling the search process not to start. Other issues can be understood throughout the specification.

Be, the new based on the search key image retrieval processing is controlled not to start, the display means, in response to switched from shooting mode for capturing an image on a reproduction mode for reproducing an image, the The image retrieved by the retrieval means is displayed .

In addition, the present invention is an imaging device that captures an image and records it on a recording medium, the imaging device capturing a search key image in response to an imaging instruction for the search key image, and a search captured by the imaging unit Search means for searching for an image from images recorded on the recording medium based on a key image; and control means for starting a search by the search means in response to the search key image being captured. The imaging means can capture an image in parallel with the search processing based on the search key image by the search means, and a new search key image can be acquired during the image search by the search means. when a photographing instruction is inputted, have a notification means for notifying that the search process in which based on other key images, the imaging means, the imaging mode for capturing an image, the shutter button is operated When a normal image is captured in response to the operation, the search key image is captured in response to simultaneous operation of the shutter button and the search button, and the shutter button is operated in the playback mode in which the image is played back. According to this, a search key image is captured .

As described above, according to the present invention, it is possible to shoot another image while searching for an image based on the captured image, and when a search process based on another search key image is being performed, Even if an image is captured, it is possible to reduce the load of the search process by controlling so that the search process based on the image is not started.

  In the following, an embodiment useful for understanding the high-level concept, middle-level concept, and low-level concept of the present invention is shown. Note that not all of the concepts included in the following embodiments are described in the claims. However, it should be understood that this is not intentionally excluded from the technical scope of the patented invention, but is not described in the scope of claims because it is equivalent to the patented invention.

  In the following embodiments of the present invention, an imaging apparatus having an image search function is mainly taken into consideration. In the image search, when an image is used as a search key image, another image related to the search key image is extracted. As a detailed method of image search, there is a technique for comparing file names, acquisition times, comment information, and the like in addition to comparing images disclosed in the above-described prior art. Needless to say, the present invention is not influenced by the image search method, and various image search methods can be adopted.

[First Embodiment]

In addition, a storage medium storage unit that is covered with a lid at the time of imaging or the like is provided on the side surface of the imaging apparatus 100, and the storage medium 30 is attached thereto. Examples of the storage medium 30 include a memory card that can be repeatedly read and written, such as a CF card (Compact Flash (registered trademark) card), a magnetic recording medium, an optical recording medium, or a magneto-optical recording medium.

  On the other hand, the internal structure and the like of the image pickup apparatus 100 will be described. In FIG. 1, A is an image to be picked up, 11 is an optical system such as a lens, 12 is a CCD (or a CMOS area sensor, etc.) that is an image pickup device, It is. Reference numeral 14 denotes an image processing unit that performs signal processing on RGB signals adapted to human vision, such as shading correction and gamma conversion, on the digital image input signal input via the AD conversion unit 13.

  Reference numeral 28 denotes a communication circuit as a communication means that should perform a communication function with other information devices. The communication circuit 28 performs operations compliant with standards such as USB, LAN, wireless LAN, IrDA, Bluetooth, IEEE 1394, and the like. The communication circuit 28 communicates with another information device 200 via a communication unit 228 mounted on another information device 200 such as a PC or a printer. As a result, the image data captured by the imaging apparatus 100 can be transferred to a PC and stored, or directly printed by a printer or the like. It is also possible to remotely control the imaging apparatus 100 from another information device 200.

  The display unit 20 described above is connected to the main CPU bus 29 via the display unit IF 21 and can be driven from the (main) CPU 17. Similarly, the operation unit including the above-described 22A shutter button, 22B search button, 22C mode setting jog dial, 22D power switch, 22E display & file operation related button, 22F ZOOM & WIDE button, 22G DISP button, and the like. 22 is connected to the main CPU bus 29 via the operation unit IF23. As a result, the imaging apparatus 100 recognizes a command input from the operation unit 22 through the operation unit IF23.

  Further, as shown in FIG. 1, the above-described storage medium 30 is connected to the main CPU bus 29 via the storage medium IF 31. Here, the internal area of the storage medium 30 can be divided into a normal image storage area 301 and a search key image storage area 302. Various means for separating the two regions are conceivable. For example, the two areas may be separated by creating separate folders (directories) in the initial sequence of the imaging apparatus, or may be separated so that each area can be accessed according to the address area. Good.

  The search engine 50 is a circuit that compares the search key image data with the normal image data and searches for similar image data. This may be constituted by an ASIC having a DMA (direct memory access) function, or may be constituted by a sub CPU operable in parallel with the CPU 17.

(Operation in imaging mode)
FIG. 3 is a state transition diagram illustrating mode transition of the imaging apparatus according to the first embodiment. FIG. 4 is a flowchart showing an imaging operation and a writing process to the storage medium 30 according to the first embodiment. FIG. 5 is a flowchart illustrating an imaging operation and search processing according to the first embodiment. First, the operation in the imaging mode will be described with reference to these drawings.

  It is assumed that the mode setting jog dial 22C is set to the imaging mode and the power is turned on by pressing the power switch 22D. In this case, when a considerable time elapses after the power is turned on and the initial sequence and the like are completed, the state transitions to the imaging mode state (T1) shown in FIG. 3, and the imaging apparatus 100 enters a standby state.

  When the shutter button 22A is pressed in the imaging apparatus 100 that is currently in the imaging mode (T1) and is in a standby state, normal imaging processing is executed. That is, an image to be captured is captured by the imaging unit and stored in the storage medium 30 as a normal image. On the other hand, in the embodiment, it is possible to capture and store a search key image even from this state. For example, a search key image can be captured and stored by simultaneously pressing the shutter button 22A and the search button 22B. By adopting such a configuration, it is possible to easily separate the imaging of the normal image and the imaging of the search key image in the imaging mode.

  In step S400, the CPU 17 polls the state of the jog dial 22C of the operation unit IF 23 to determine whether or not the imaging mode has ended. If completed, this flowchart is terminated. On the other hand, if the imaging mode is maintained, the process proceeds to step S401.

In step S401, the CPU 17 determines whether or not at least the shutter button 22A has been pressed. For example, since the shutter button ON signal is generated in the operation unit IF23 when the shutter button 22A is pressed, the CPU 17 can detect the ON signal by executing polling. On the other hand, when the shutter button 22A and the search button 22B are simultaneously pressed, a search key image pickup signal (simultaneous push button signal) is generated in the operation unit IF 23 in addition to the shutter button ON signal. The generated shutter button ON signal is transmitted to the (main) CPU 17 regardless of whether the normal image is captured or the search key image is captured. In detecting the shutter button ON signal, instead of the polling operation, for example, a configuration of detecting by an interrupt process may be adopted. If the shutter button ON signal cannot be detected, the process returns to step S400. On the other hand, if detected, the process proceeds to step S402.

  In step S402, the CPU 17 starts an imaging operation. Specifically, the image of the image A to be captured that is incident on the CCD 12 via the optical system 11 is photoelectrically converted by the CCD 12 for each pixel and sent to the AD conversion unit 13. The AD conversion unit 13 performs AD conversion on analog values relating to the shade of each color of each pixel, and sends the analog value to the image processing unit 14. Next, the image processing unit 14 performs signal processing such as shading correction and gamma conversion on the input digital image input signal to convert it into an RGB signal suitable for human vision. As a result, each pixel data of the still image data subjected to the image processing is sequentially written and stored in the RAM 16 via the RAM controller 15. When all pixel data and attached data for one image are written in the RAM 16, the imaging operation for one image is completed. In the present embodiment, every time an image capturing operation is completed, the data is not immediately written to the storage medium 30, but is written together.

  In step S403, the CPU 17 determines whether the image data stored in the RAM 16 is normal image data or search key image data. This determination is made by checking whether or not the search key image pickup signal is generated by the CPU 17 accessing the operation unit IF23. If the result of the determination is that the imaging operation is a normal image, the process proceeds to step S404 (T3). On the other hand, if it is imaging of search key image data, it will progress to step S405 (T4).

  In step S404, the CPU 17 writes the image written and stored in the RAM 16 into the storage medium 30 as a normal image. For example, the CPU 17 transfers the image stored in the RAM 16 to the normal image storage area 301 of the storage medium 30 and stores it.

  In step S405, the CPU 17 writes the image written and stored in the RAM 16 into the storage medium 30 as a search key image. For example, the imaging apparatus 100 transfers the image stored in the RAM 16 to the search key image storage area 302 of the storage medium 30 and stores it.

  As described above, when acquiring normal image data, the operation of only the shutter button is used as an operation input. On the other hand, when acquiring search key image data, the simultaneous push button of the shutter button and the search button is used as an operation input. Thus, both are input to the CPU 17 in different operation modes. Therefore, the user will be able to clearly select and select two types of imaging operations.

  Further, the normal image and the search key image are stored in the same storage medium, and the search key image data is distinguished from the normal image data by separating the normal image storage area and the search key image storage area. It can be stored in a storage medium in such a manner. In general, since the number of search key image data is smaller than the number of normal image data, the search key image can be easily and quickly extracted from the storage medium 30 and selected.

  Further, since the search key image data is stored in the nonvolatile storage medium 30, the search key image data can be used repeatedly.

  In addition, since the search key image data and the normal image data are stored in different storage areas, it is possible to easily distinguish them from each other, which is very useful.

  In particular, it is expected that the number of normal images stored in one storage medium will increase dramatically in the future due to the increase in the capacity of the storage medium. Even in such a situation, the retrieval key image can be quickly extracted, which is a very effective technique.

  Preferably, when a search key image is captured, the CPU 17 compresses the image data in step S405 before transferring and storing the image written and stored in the RAM 16 to the search key image storage area 302. Alternatively, the data may be transferred to and stored in the storage medium 30 after thinning out. In this case, it is desirable to employ a compression rate higher than that of the normal image. This is because it is not always necessary for the search key image to have a higher image quality than a normal image. Therefore, by performing compression processing or the like, it is possible to save the storage capacity necessary for storing the search key image, and as a result, it is possible to store more image data in the storage medium 30, which is very useful.

  By the way, as described above, when the shutter button 22A and the search button 22B are pressed at the same time in the imaging mode (T1), a search key image is captured and search processing in the storage medium 30 in the imaging device 100 is started. May be.

  Hereinafter, the operation in this case will be described with reference to the flowchart shown in FIG. The portions described in FIG. 4 are denoted by the same reference numerals, and the description thereof is omitted.

  In step S403, for example, if the CPU 17 determines that the shutter button 22A and the search button 22B are pressed simultaneously to instruct the search key image capturing operation, the process proceeds to step S501. Note that the simultaneous pressing of the shutter button 22A and the search button 22B means the start of the image search process. Note that the image search process is started upon completion of imaging of the search key image (that is, the image can be used for the search process).

  In step S501, the CPU 17 determines whether another search process is already running. Since the search process is an extremely heavy process, if a plurality of search processes are started in parallel, there is a risk of adversely affecting the imaging process, the reproduction process, and the like. Therefore, the parallel activation of a plurality of search processes is prohibited. If another search process has been started, the process proceeds to step S502, and the CPU 17 displays a message indicating “other search is in progress” on the display unit 20 via the display unit IF21. On the other hand, if no other search process is activated, the process proceeds to step S503. Note that steps S501 and S502 are optional and may be omitted. That is, if the processing capacity of the CPU 17 or the search engine 50 is high, a plurality of image searches can be performed in parallel.

  In step S <b> 503, the CPU 17 starts the search process while maintaining the imaging mode (T <b> 1). In the search process, for example, the following operation is performed. When the search process is activated, a search flag is set in the search engine 50. The search engine 50 sequentially reads the normal images in the storage medium 30 and transfers them to the RAM 16 by direct memory access (DMA) operation without going through the CPU 17. At this time, the normal image may be transferred to an area different from the search key image. Then, the search engine 50 sequentially compares the image read by the DMA operation with the image that has just been captured. If there is a similar image, the image is stored in another area in the RAM 16. When all the normal images in the storage medium 30 have been compared in this manner, the search engine 50 is searching while holding the similar image that is the search result stored in the other area in the RAM 16. The flag is canceled and the search result presence flag in the search engine is set. In addition, the search engine 50 generates a search end interrupt to the CPU 17. As a result, a series of search processing ends. The search result may be displayed on the display unit 20 by the CPU 17 after the search is completed, or may be displayed when a playback mode described later is entered. In the latter case, if the CPU 17 reads the search result presence flag and determines that there is a search result, the search result image is displayed on the display unit 20.

  The search process is started as described above, and the search key image that has just been captured and stored in the RAM 16 may be transferred and stored in the search key image storage area 302 of the storage medium 30 ( S405). However, the search key image in this case may be deleted from the RAM 16 without performing the writing operation when the search process is completed.

  When the search process is started (S503) and the search key image data writing operation (S405) performed as necessary is completed, the CPU 17 does not wait for the search engine 50 to end the search process. The search image data imaging process ends. In this case, even if the CPU 17 becomes ready to execute the next imaging operation, the search engine 50 may continue the search process in the background. That is, since the search process is performed by the DMA operation by the search engine 50, the CPU 17 can execute the image capturing process in parallel. That is, a normal image can be captured, and a search key image can also be captured. However, the retrieval of the retrieval key image is controlled so that the CPU 17 rejects or prohibits the retrieval end interrupt or the retrieval flag is released. Incidentally, it is possible to shift to the playback mode (T2) during the search and perform the playback operation. This is because the CPU 17 is almost in charge of processing related to the playback mode.

  On the other hand, when the CPU 17 refers to the searching flag during the search, the fact that the search is being performed can be displayed on the display unit 20. Therefore, the user can recognize that the search process is being executed in the background in the imaging mode. Further, if the CPU 17 recognizes the occurrence of the search end interrupt or the cancellation of the searching flag, the fact that the search has ended may be displayed on the display unit 20. In this way, the user can grasp whether or not the retrieval key image can be captured. That is, when the search is completed, the search key image can be captured. If the search engine 50 controls the search engine 50 so as not to overwrite the search key image being used, another search key image can be captured even during the search.

  As described above, according to the present embodiment, the search key image data is imaged only by pressing the shutter button and the search button at the same time, and the image search process using the search key image data is started. Not only can the search key image be easily distinguished, but the image search can be started immediately after the search key image is captured. That is, the operation of pressing the search button after the imaging process is unnecessary, and the user's operation can be reduced.

  Further, by adopting the search engine 50 that can operate in parallel with the CPU 17, it is possible to appropriately perform the imaging operation and the reproduction operation while continuing the search process, so that a very useful imaging device will be provided.

(Operation in playback mode)
Next, it is assumed that the mode setting jog dial 22C is set to the reproduction mode and the power is turned on by pressing the power switch 22D. In this case, when a considerable time has elapsed after the power is turned on and the initial sequence and the like are completed, the imaging apparatus 100 transitions to the standby state in the reproduction mode state (T2) shown in FIG. Hereinafter, processing in the reproduction mode will be described with reference to FIGS. In particular, FIG. 6 is a flowchart showing the operation of the playback mode according to the first embodiment. It is assumed that this flowchart is started when a transition is made to the standby state (T2) in the reproduction mode.

  In step S601, the CPU 17 accesses the search engine 50 and reads a search result presence flag stored in the search engine. Note that access means transmission of a command, reception of a response, transmission / reception of data or a signal, reading / writing of data, and the like.

  In step S602, the CPU 17 determines whether or not the read search result presence flag is set to mean the presence of the search result. That is, if this flag is asserted, it means that the search process is executed in the imaging mode and the search process is finished. Accordingly, the process proceeds to step S603.

  In step S <b> 603, the CPU 17 reads out the search result (similar image data) stored in a partial area of the RAM 16 and displays it on the display unit 20. As described above, the search result during the imaging mode is displayed as soon as the mode is changed to the reproduction mode (T2). In general, when the mode is changed to the reproduction mode, there are many cases where the user has room, so that it is preferable for the user to check the search result.

  In step S604, the CPU 17 determines whether or not a button (for example, a search button) indicating the end of display of the search result has been pressed. In this case, the operation unit IF23 generates a search display end flag in conjunction with the search button 22B. The CPU 17 can detect a search result display command by detecting this by polling or by interrupt. That is, when the user confirms the search result and presses the search button again, the display of the search result is terminated, and the process proceeds to step S605.

  In step S605, the CPU 17 transitions to an operation in a normal playback mode.

  On the other hand, if the search result existence flag in the search engine 50 is read in step S602 and this flag is not asserted, the search process is not performed during the imaging mode or the search process is not completed. It will be. In this case, the process proceeds to step S605, and the CPU 17 displays a normal image on the display unit 20. As a display method in this case, various methods such as a method of displaying only one latest image and a method of displaying a plurality of thumbnail images can be adopted.

  Although not shown in the flowchart, when a normal image is displayed on the display unit 20, the CPU 17 stores the storage medium 30 in response to an operation input of the operation related button 22E such as an arrow key for inputting a display operation or a file operation. The normal images stored in are sequentially displayed. Further, the CPU 17 may execute thumbnail display, zoom display of image data, and the like. It should be noted that thumbnail display and zoom display are well-known techniques, and those skilled in the art can sufficiently implement them.

  In step S606, the CPU 17 performs polling for detecting the end of the reproduction mode in parallel with the display process on the display unit 20. If not completed, the process proceeds to step S607, and the CPU 17 repeats polling regarding the search result presence flag. If the search result is newly stored in the storage medium 30 or the like, the process proceeds to step S603, and the search result is displayed. If the display operation is finished, the CPU 17 negates the search result existence flag of the search engine 50 (S604). Therefore, the process always proceeds to S608 until the next switching to the imaging mode.

  Thus, if there is no search result, the process proceeds to step S608, and the CPU 17 continues to poll the push buttons of various buttons. Examples of the various buttons include a shutter button 22A, a search button 22B, and a search key image selection button in the display & file operation related button 22E. Of course, instead of boring, push buttons of these various buttons may be detected by interrupt processing. When the shutter button 22A (operation unit 22) is pressed by the user, the operation unit IF23 shown in FIG. 1 generates a shutter button ON signal. On the other hand, when the shutter button 22A and the search button 22B are pressed at the same time, a simultaneous pressing signal is generated in the operation unit IF23 in addition to the shutter button ON signal.

  In the polling process of step S606, when the CPU 17 detects that the mode setting jog dial 22C has been changed to another operation mode such as the imaging mode or the power switch 22D has been pressed, the playback mode is terminated.

  On the other hand, when the CPU 17 detects the push button of the shutter button 22A, the CPU 17 proceeds to step S609 and executes a search key image imaging process (FIG. 7). When the push button of the search button 22B is detected, the process proceeds to step S610, and search processing is executed (FIG. 8). If a push button of the search key image selection button is detected, the process advances to step S611 to execute search key image selection processing (FIG. 9).

(A) When Push Button of Shutter Button 22A is Detected FIG. 7 is a flowchart showing a search key image capturing subroutine according to the first embodiment. This flowchart corresponds to step S609 in FIG. 6, and is started when the CPU 17 detects, for example, the push button of the shutter button 22A in the reproduction mode. In this case, instead of capturing a normal image, a search key image for image search is captured.

  As described above, when it is detected that the shutter button is pressed while the jog dial as the mode selection unit is set to the reproduction mode, the CPU 17 captures the search key image data. That is, as described above, when the shutter button is pressed in the imaging mode, the operation mode is different from the case where normal image data is captured. Therefore, it is possible to easily separate normal image capturing and search key image capturing. Further, there is an advantage that the search key image can be easily captured even in the reproduction mode without switching to the imaging mode.

  In step S701, the CPU 17 shifts to a search key image capturing mode (T3) which is a transitional mode. In general, since the playback mode is not a state in which the imaging apparatus 100 can capture an image, preparation for imaging is necessary. For example, the CPU 17 activates the CCD (or CMOS area sensor or the like) 12 or the like, the AD conversion unit 13 or the image processing unit 14 or the like, and changes to a state in which imaging is possible. To make it ready for imaging. When the imaging preparation is completed, the process proceeds to the search key image imaging operation.

  In step S702, the CPU 17 performs an imaging operation. The CPU 17 writes all pixel data and attached data for one image in the RAM 16 by the same principle and operation as the imaging in the imaging mode. Thus, the search key image capturing operation for one image is completed. Note that in the present embodiment, it is the imaging mode that does not immediately write the data to the storage medium 30 at the end of each imaging operation, but writes them together as described later. It is the same.

  In step S703, the CPU 17 detects and determines whether or not the simultaneous pressing signal for the operation unit IF23 is generated. When the simultaneous push signal is generated, the shutter button 22A and the search button 22B are pushed simultaneously. According to the embodiment of the present invention, when both buttons are pressed simultaneously in the playback mode, the CPU 17 captures the search key image and stores the search key image in the storage medium 30 and also searches the search engine 50. Start the search process. On the other hand, when only the shutter button is pressed, the CPU 17 simply captures the search key image and stores it in the storage medium 30 and does not start the search process. In other words, in the playback mode, it is possible to determine whether to start the search process immediately after capturing the search key image or to perform only storing by capturing the search key image, depending on whether or not they are simultaneously pressed. . Note that the simultaneous pressing may be imaging / memory, and the case where only the shutter button is pressed may be the start of imaging and search processing. In short, although the shutter buttons are operated in common, the operation modes may be different as a whole. Note that the operation of the shutter button is not necessarily required, and as a result, different operation modes may be used so that the normal image capturing and the search key image capturing can be clearly separated.

  If the simultaneous pressing signal is detected, the process proceeds to step S704, and if the simultaneous pressing signal is not detected, the process proceeds to step S712.

  In step S704, the CPU 17 accesses the searching flag to check whether another search process still remains. At this time, there is a possibility that the search process that was previously started in the imaging mode or the like is still being executed, but it is not preferable to start two or more search processes, so this flag is checked. However, if a plurality of search engines can be provided to reduce the search load, a plurality of search processes may be operated in parallel. If the searching flag is asserted, it means that another search process is currently being executed, and the process proceeds to step S711. On the other hand, if the searching flag is not asserted, the process proceeds to step S705.

  In step S711, the CPU 17 displays on the display unit 20 that another search is being executed, and proceeds to step S712 without starting a new search process.

  In step S <b> 705, the CPU 17 sends a search command to the search engine 50 so as to search based on the search key image that has been captured and stored in the RAM 16. The search engine 50 starts the above-described search process according to this command.

  In step S706 and step S712, the CPU 17 writes the latest search key image stored in the RAM 16 in the search key image storage area 302 of the storage medium 30. However, if the search process is started in S705, the search key image used for the search process may be discarded after the search process is completed without being stored in the storage medium 30.

  In steps S707 and S713, the CPU 17 exits the search key image capturing mode (T6) and returns to the standby state (T2) of the reproduction mode. For example, when the optical system 11 employs a retractable lens, the CPU 17 controls the movement of the lens to the retracted position.

  If the search process is not activated in this playback mode and S713 ends, the series of procedures ends here, and the subroutine is exited. That is, the CPU 17 displays the normal image on the display unit 20 (S605), and returns to the original polling state and the like (S606 to S608).

  On the other hand, when the search process is activated, in step S708, the CPU 17 waits for polling to generate a search end interrupt or to release the searching flag. Until the search process is completed, nothing may be displayed on the display unit 20, or a normal image or the like may be displayed. Further, the CPU 17 may sequentially display the searched and extracted images, or display the images using a thumbnail method. If it is determined that the search process has been completed, the process proceeds to step S709.

  In step S709, the CPU 17 displays all the results on the display unit 20 sequentially or in a thumbnail format. This allows the user to access all search results.

  In step S710, the CPU 17 determines whether or not to end the search key image capturing mode. For example, in the operation unit IF 23, the search button 22B is pushed again, and the CPU 17 checks whether or not a search button ON signal is generated. When detecting the search button ON signal indicating the end, the CPU 17 ends this subroutine and returns to the main routine. That is, the CPU 17 displays the normal image on the display unit 20 (S605), and returns to the original polling state and the like (S606 to S608).

(B) When the push button of the search button 22B is detected In step S608 in FIG. 6, when the search button 22B is pressed during the playback mode, the search process is executed using the search key image selected at this time. The

  FIG. 8 is a flowchart of a search subroutine according to the first embodiment. This subroutine corresponds to step S610.

  In step S801, the CPU 17 accesses the searching flag and checks whether another search process is being activated. If the search flag is asserted, it means that another search process is currently being executed, and the process advances to step S806, and the CPU 17 displays a message indicating that another search process is being executed. The subroutine is terminated without starting a new search process. On the other hand, if the search flag is not asserted, it means that no other search process is currently being executed, and the process advances to step S802.

  In step S <b> 802, the CPU 17 sends a search processing start command to the search engine 50. The search engine 50 starts search processing based on the currently set search key image. It is assumed that an arbitrary search key image is always selected as a search key by the CPU 17 and stored in a specific area of the RAM 16.

  For example, if the selected search key image adopts a configuration in which the most recently acquired search key image is selected, the user can start a search with a one-touch operation by simply pressing the search button 22B in the playback mode. There are advantages you can do. In addition, a search key image that is highly likely to be used for search can be set. On the other hand, you may employ | adopt the structure from which the search key image acquired the oldest is selected. Further, the selected search key image may be displayed on all or part of the display unit 20. On the other hand, when it is desired to perform a search process using a search key image different from the key image selected by the imaging apparatus 100, the search key image is changed by pressing a search key image selection button described later in FIG. Settings can be made.

  In step S <b> 803, the CPU 17 waits for polling to generate a search end interrupt or release the searching flag. Until the search process is completed, nothing may be displayed on the display unit 20, or a normal image or the like may be displayed. Alternatively, the searched and extracted images may be sequentially displayed or displayed by a thumbnail method. If it is determined that the search process has been completed, the process proceeds to step S804.

  In step S804, the CPU 17 displays all the results on the display unit 20 sequentially or in a thumbnail format. This gives the user access to all search results.

  In step S805, the CPU 17 determines whether or not the search process should be terminated. Since this is as described in step S710, description thereof is omitted.

(C) When the push button of the search key image selection button is detected When the search key image selection button, which is one of the display & file operation related buttons 22E, is detected in the playback mode, the search key used for the search is detected. Image change and selection processing is started.

  FIG. 9 is a flowchart of a search key image selection subroutine according to the first embodiment. This subroutine corresponds to step S611 described above.

  In step S901, the CPU 17 accesses the searching flag and checks whether another search process is being activated. At this time, there is a possibility that the search process is still being executed. In this search process, the search key image selected previously is used. If the search key image is changed unnecessarily, the search processing during activation will be affected. Therefore, it is necessary to prohibit the selection change processing of the search key image. Therefore, in this step, it is confirmed whether or not the previously started search process is still being executed. If no other search process is active, the process advances to step S902. On the other hand, if it is activated, the process proceeds to step S904, where the CPU 17 displays a warning display such as “other search in progress” on the display unit 20, and exits this subroutine.

  In step S902, the CPU 17 shifts to the search key image set mode (T8). Here, first, the CPU 17 reads the search key image from the search key image storage area 302 in the storage medium 30 and displays it. In that case, for example, the CPU 17 sorts the image data in order of acquisition time or file name, and reads out and displays the image data in accordance with the sorted order. Of course, thumbnail display is also possible. By taking such a configuration, it will be easy to find the search key image.

  In the search key image set mode (T8), an arrow key (triangular key) that is one of the display & file operation related buttons 22E, a confirmation button that is also one of the display & file operation related buttons 22E, and the like are displayed on the CPU 17. Is ready to accept. Therefore, one search key image can be selected from the displayed images by using the arrow keys (triangular keys). That is, the user can select one search key image stored in the storage medium 30. When the push button of the confirmation button is detected at the time of selection, the CPU 17 changes and selects the search key image used for the search.

  In step S903, the CPU 17 determines whether or not the search key image set mode should be terminated. For example, when the push button of the search key image selection button is detected again, this subroutine is terminated and the process returns to step S605.

  As described above, in the first embodiment, the first operation input when acquiring normal image data and the second operation input when acquiring search key image data are input in different operation modes. Therefore, the two types of imaging operations of the normal image and the search key image can be clearly separated. In either case, since the shutter button 22A is used at least, the user can clearly separate the two types of imaging operations while being aware that imaging is being performed. In addition, since the operation input for acquiring the search key image data can be input by using the shutter button 22A in combination with another button, it is possible to perform the search with a simple operation while being aware of the imaging process. Key images can be taken. Note that it is desirable that the shutter button 22A and the other buttons be arranged at positions where they can be pressed simultaneously.

  In the first embodiment, the search key image data can be acquired while in a mode other than the imaging mode by at least operating the shutter button in the playback mode.

  In the first embodiment, the search can be started immediately after the retrieval key image is captured by performing the second operation input in the imaging mode and the reproduction mode. When only the first operation input is made in the playback mode, a search key image is recorded and the search is saved. Therefore, these can be separated by a plurality of different operation inputs.

  Also, by making full use of the shutter button and search button according to the mode such as the imaging mode and playback mode, not only can the search be performed easily using the captured image, but the normal image and the search key image can be distinguished on the same storage medium. Store in a possible manner. Therefore, even after imaging, both can be distinguished and recognized. Note that the search key image can be repeatedly used by storing the search key image in a non-volatile storage medium such as a flash memory.

  Moreover, in the said embodiment, the image used as a search key image can be directly imaged. As a result, the input of the search key image becomes extremely easy, so that the search function can be easily used.

  In addition, according to the present embodiment, since the search engine 50 that operates in parallel with the CPU 17 that controls the imaging process, the reproduction process, and the like is mounted, the image can be obtained even during the execution of the search extraction process. There is an advantage that the image pickup and reproduction can be continued.

  Also, according to the playback mode of this embodiment, arbitrary image data such as search image data with the latest acquisition time or the oldest search image data is set in advance as a search key. The search process can be started simply by operating the search button.

(Second Embodiment)
In the present embodiment, the management method for normal image data and search key image data is changed from the above-described embodiments.

  FIG. 10 is a diagram illustrating a configuration example of an imaging apparatus according to the second embodiment. As compared with FIG. 1, it can be understood that the storage method of the image data in the storage medium 30 is different. In the first embodiment, the storage medium 30 includes the normal image storage area 301 and the search key image storage area 302. On the other hand, in the second embodiment, both the normal image and the search key image are stored in the same area of the storage medium 30. Instead, different file management information is attached to the FAT (file allocation table) portion of the normal image file and the FAT portion of the search key image. In the present embodiment, a data bit “0” is set in the reference portion of the FAT portion of the normal image, and a data bit “1” is set in the reference portion of the search key image. Note that the file management information may be provided in the image information itself.

  That is, when storing the search key image in the storage medium 30 in S405, S706, or S712, the CPU 17 stores the storage area without being particularly conscious of it, but in the FAT unit or the search key image data file, etc. In addition, file management information different from that of normal image data is added and stored. With this configuration, the normal image and the search key image can be easily distinguished.

  In step S902, when designating the search key image, the CPU 17 reads the image data with the file management information indicating the search key image from the storage medium 30, thereby displaying the search key image candidates on the display unit 20. Can be displayed.

  As described above, according to the present embodiment, the identification information indicating that it is different from the normal image data is added to the file management information of the search key image data and stored in the storage medium 30, thereby storing both storage areas. The same convenience as in the first embodiment can be obtained without dividing the above.

(Third embodiment)
In the above embodiment, the normal image and the search key image are separately stored in the storage medium 30.

  However, it may be inconvenient that the search key image cannot be used as a normal image. There are many problems especially when the search key image is good. For example, it is conceivable to duplicate the search key image as normal image data, but in this case, the same image data is stored twice, and the storage capacity of the storage medium is wasted. However, if the search key image is searched for and set from all the normal images as in the prior art, the operation becomes complicated.

  Therefore, in the third embodiment, all images are handled as normal images. However, normal images that are also used as search key images are given different file management information inside the FAT section or file. . Here, as in the second embodiment, the data bit “0” is set in the reference portion of the normal image, and the data bit “1” is set in the reference portion of the search key image.

  FIG. 11 is a diagram illustrating a configuration example of an imaging apparatus according to the third embodiment. In the third embodiment, what has been handled as a search key image (dedicated) in the first and second embodiments is handled as a combined image of the search key image and the normal image.

  When storing the search key image in the storage medium 30 in S404, S405, S706, or S712, the CPU 17 attaches file management information indicating a combined image to the FAT unit or the search key image data file. And remember. The file management information meaning the combined image may be any information as long as it can be distinguished from the file management information dedicated to the normal image and the file management information dedicated to the search key image.

  Note that the storage area may be stored without being particularly conscious, or may be stored separately into the normal image storage area 301 and the search key image storage area 302 as shown in FIG. That is, the search key image data stored in the search key image storage area 302 can be handled as a combined image, and the normal image data stored in the normal image storage area 301 can be handled as a combined image. This is because the shared image can be distinguished by the file management information in any case.

  In step S <b> 902, when designating a search key image, the CPU 17 can display search key image candidates on the display unit 20 by reading out image data with file management information indicating a shared image from the storage medium 30. . In this way, the same convenience as in the first embodiment can be obtained, which is very useful.

  As described above, in the third embodiment, image data that is also used as a search key image among normal images or image data that is also used as a normal image among search key images means a common image. Since the information is attached, it is not necessary to store both of them in duplicate, and the storage capacity of the storage medium can be used effectively. In addition, there is an advantage that the search key image can be easily searched.

(Fourth embodiment)
In each of the first, second, and third embodiments, when image data is written to the storage medium 30, the search key image or the normal image is stored in a distinguishable manner. However, when the storage medium 30 is detachable and replaceable, image data captured by another imaging device may be stored. In addition, when such a storage medium 30 is used in the imaging apparatus 100, the search key image in the storage medium 30 may not be distinguished from the normal image.

  Therefore, in the fourth embodiment, an imaging apparatus that is useful even in such a case will be described.

  FIG. 12 is a diagram illustrating a configuration example of an imaging apparatus according to the fourth embodiment. In this example, for convenience of explanation, it is assumed that all the image data is stored in the storage medium 30 in the same state. Note that the imaging apparatus 100 illustrated in FIG. 12 may or may not have the functions described in the first embodiment. In this case, the imaging apparatus may not store the search key image and the normal image separately in the storage medium 30, or may store them separately.

  FIG. 13 is a flowchart showing the operation of the playback mode according to the fourth embodiment. The portions described in FIG. 6 are denoted by the same reference numerals, and the description thereof is omitted. Note that the operation when the shutter button is pressed in the playback mode is described as being the same as the operation shown in FIG. 6, but there may be differences.

  According to FIG. 13, if a search key image specifying button is detected in step S608, the process proceeds to step S1301, and search key image specifying processing is executed. It is assumed that a specific button of the search key image is also included in the operation unit 22.

  That is, in order to use image data written by another imaging device or the like as a search key image, a process for specifying the search key image is required.

  This search key image specifying button is different from the above-described search key image selection button for only the search key image in the sense that it enters a mode for searching for an image to be assigned to the search key image from all images. As the search key image specifying button, one of the display & file operation related buttons 22E may be newly assigned, or may be assigned instead of the search key image selection button.

FIG. 14 is a flowchart showing a search key image specifying subroutine according to the fourth embodiment. This subroutine corresponds to step S1301 in FIG. In addition, the description is abbreviate | omitted by attaching | subjecting the same reference number about the part demonstrated in FIG.

  In step S901, the CPU 17 confirms activation of another search process. In step S902, the image data stored in the storage medium 30 is read and displayed as a candidate on the display unit 20. When any image data is specified by the operation unit 22, the process proceeds to step S1401. This is different from the above-described change and selection of the search key image in that the search key image is specified from all the images.

  In step S1401, the CPU 17 determines whether or not to store the image data specified by the operation unit 20 as a search key image after the state of the search key image set mode or the specifying process ends. For example, the CPU 17 determines that the image data should be stored in the storage medium 30 as a search key image by detecting the push button of the save button assigned with one of the display & file operation related buttons 22E. If it should be saved, the process proceeds to step S1402.

  In step S1402, the CPU 17 stores the specified image data in the storage medium 30 as a search key image.

  In this way, one of the image data that has only been stored in the storage medium 30 can be identified and overwritten or stored in the storage medium 30 as a search key image. At this time, the search key image storage area 302 may be created and stored there, or may be stored with file management information representing the search key image or the combined image.

  Thereafter, when it is determined in step S903 that the specific process should be terminated, the CPU 17 returns to the main routine.

According to the fourth embodiment, even when it is not possible to distinguish whether the image data stored in the storage medium 30 is a search key image or a normal image, the search key image can be easily specified. For example, this is effective when the storage device 30 including image data captured by another imaging device is used in the imaging device 100.
Since the image data specified as the search key image is stored in the storage medium 30 as the search key image, the search key image is stored in the imaging device according to the first, second, or third embodiment. 100 can be used meaningfully.

(Fifth embodiment)
In the fifth embodiment, the search subroutine shown in FIG. 8 is improved. Depending on the convenience of the user, for example, it is conceivable to select an image slightly far from the desired search key image and start the search process. In that case, a desired search key image or an image closer thereto may be searched and extracted during the search. In that case, it is considered that the search noise is reduced and a refined search result can be obtained by performing a search by setting an image closer to the search and extraction as a search key image. Therefore, in this embodiment, image data discovered during the search process is selected as a search key so that the search process can be executed again.

  FIG. 15 is a flowchart showing a search subroutine according to the fifth embodiment. This subroutine corresponds to step S610 in FIG. 6 or FIG. In addition, the part demonstrated in FIG. 8 attaches | subjects the same referential mark, and abbreviate | omits description. In the following, it is assumed that image data that is newly specified as a search key image is retrieved and displayed on the display unit 20 in step S804.

  In step S1501, the CPU 17 determines whether a new search key image has been designated from the search result. For example, when an image appearing from the search result is designated by an arrow key (triangular key) or the like and the search button 22B is detected again, the CPU 17 re-uses the designated image data as a search key image. In step S802, image search is activated using the search key image.

  On the other hand, if it is not re-selection, the process proceeds to step S1502, and the CPU 17 determines whether or not to save the search result as a search key image. For example, the determination process is executed by detecting that the search result image or the search key image used at that time is designated by an arrow key (triangle key) or the like and the save button is pressed. To do. If it is determined that the search result should be saved as a search key image, the process proceeds to step S1503, and if not, the process proceeds to step S805.

  In step 1503, the CPU 17 stores the designated image data in the storage medium 30. The method for storing the search key image is as described above.

  As described above, according to the present embodiment, a new search key image can be specified from the image data that has been searched and extracted so that the search process can be executed again. There is an advantage that can be executed by simple operation. For example, since the number of image data stored in the storage medium 30 is enormous, first, search processing is started with an image slightly distant from the desired search key image, and when closer image data appears, The image can be designated as a new search key image and the search can be executed again. As the search is repeated in this way, the extraction probability of an image close to the desired search key image will be improved.

(Sixth embodiment)
A technique for mutually converting a search key image and a normal image in the sixth embodiment will be described.

  FIG. 16 is a flowchart showing the operation of the playback mode according to the sixth embodiment. In addition, about the location demonstrated in FIG. 6, description is abbreviate | omitted by attaching | subjecting the same referential mark.

  First, in step S605, when a normal image is displayed on the display unit 20, it is assumed that a specific normal image is designated with an arrow key (triangular key).

  In step S1601, the CPU 17 detects the push button of the change button to which one of the display & file operation related buttons 22E is assigned. If detected, the process proceeds to step S1602, and the CPU 17 changes the designated normal image into a search key image and stores it in the storage medium 30. There are various methods for implementing change processing. For example, the search key image may be created by duplicating the normal image. Alternatively, the file management information of the normal image may be changed to indicate the search key image. Alternatively, a link of normal image data may be created and stored in the search key image storage area 302. Alternatively, the image data may be moved from the normal image storage area 301 to the search key image storage area 302. Of course, it is needless to say that it may be managed as the above-described combined image.

  Needless to say, steps S1601 and S1602 may be inserted into the flowchart of FIG.

  FIG. 17 is a diagram showing a search subroutine according to the sixth embodiment. In addition, about the location demonstrated in FIG. 9, description is abbreviate | omitted by attaching | subjecting the same referential mark.

  When the search key image is selected in step S902, if the change button described above is pressed in step S1701, the CPU 17 proceeds to step S1702 and changes the selected search key image to a normal image. A specific example of the change process is as described for step S1602 except that the conversion target is reversed.

  Needless to say, steps S1701 and S1702 may be inserted into the flowchart of FIG.

  As described above, according to the sixth embodiment, the search key image and the normal image can be mutually converted. For example, when an image captured as a search key image is a good image, it can be used as a normal image. On the other hand, when an image captured as a normal image can be used as a search key image, the normal image can be used as a search key image.
