Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital camera, a method for retrieving information in a digital camera, and a storage medium storing an information retrieval processing program for the digital camera, which can retrieve retrieved data efficiently.

[0002]

2. Description of the Related Art Recently, digital cameras have become remarkably popular. Unlike conventional optical cameras using film, this digital camera can transfer captured image data to a personal computer and print it out, and can perform various processing on the personal computer. It will be used in the field.

This digital camera is generally provided with a monitor screen so that an image to be captured can be captured while monitoring the image to be captured, and an already captured image can be read out on the monitor screen. Has become. However, when trying to read out the captured image information later, there is a problem that a process of searching for information of a desired page from a large number of pages is extremely troublesome.

[0004] In order to perform this information retrieval process at high speed, at the time of a continuous page feed operation, information displayed for each page is roughly displayed, thereby enabling a faster page feed operation. Accordingly, it has been conventionally possible to perform a high-speed search.

[0005] By the way, the image information has a large data amount, and when displaying all the data constituting the image information to be displayed, it takes a lot of time to display. Therefore, it is necessary to perform processing such as thinning out the original image data. Then, a method of temporarily generating and displaying simplified image information, that is, rough image information is used.

As described above, by performing a data thinning process on image information to obtain a rough image,
The time required for display can be greatly reduced, and high-speed page turning can be performed. As a result, search can be performed efficiently.

[0007]

However, simply displaying the rough image by thinning out the image data requires a higher speed of page turning to achieve a higher-speed search. Must be an image.

However, if the image is roughly simplified, the image content cannot be visually confirmed at the time of page turning, which makes it difficult to search for a desired page. For this reason, there is a certain limit to the image data thinning process, and a method that enables comfortable information retrieval by other methods is required.

Therefore, the present invention enables efficient and comfortable information retrieval by performing page turning with display contents according to a continuous page turning state when searching for captured image information. It is an object.

I have.

According to a fourth aspect of the present invention, there is provided an information retrieval method for a digital camera, wherein the fetched information is written into the storage means as page information of a page opened on the display screen, and the fetched information is read. In this case, when a desired page is opened on the display screen, information taken in the page is read out from the storage means, and information retrieval processing in a digital camera having a function of displaying the page as page information of the page is performed. In the method, when a page turning operation for reading information of a desired page is performed, it is monitored whether or not this page turning operation state is a continuous page turning operation, and the continuous page turning operation is performed. , The continuous page feed status is extracted as a signal indicating multiple stages, and a table corresponding to each stage is displayed. After up the content as page data, the display contents based on the page data, for each step, the operator displays during continuous page turning operation at that stage.

According to a fifth aspect of the present invention, in the first aspect, the process of extracting the continuous page feed state as a signal indicating a plurality of stages includes measuring a continuous page feed operation time and measuring the measured time. In response to this, a continuous page feed state is output as a signal indicating a plurality of stages.

According to a sixth aspect of the present invention, in the fourth or fifth aspect, the processing for forming the display content corresponding to the step includes receiving the signal indicating the continuous page feed state.
For each stage, during continuous page feed operation at that stage, page data for displaying either the rough display of information taken in each page or the current page position display at the time of continuous page feed operation Is configured.

According to a seventh aspect of the present invention, there is provided a processing program in a recording medium in which an information search processing program in a digital camera is recorded, when a page turning operation for reading information of a desired page is performed, It monitors whether the state is a continuous page feed operation or not, and if a continuous page feed operation is performed, fetches the continuous page feed state as a signal indicating a plurality of stages, and outputs After configuring the corresponding display content as page data, processing is performed such that the display content based on the page data is displayed for each stage during the continuous page feed operation at that stage.

As described above, the present invention monitors whether or not a page turning operation is a continuous page turning operation, and if the page turning operation is a continuous page turning operation, sets the continuous page turning state in a plurality of steps. In each of the stages, page data corresponding to each stage is formed, and the page is turned while displaying based on the page data.

That is, the continuous page turning state is determined by the time during which the continuous page turning operation is performed, and the continuous page turning operation state is determined in several stages, for example, the first stage, according to the operation time. (The degree of continuous page turning is relatively small) to the third stage (the degree of continuous page turning is large). Then, for each stage, page data corresponding to each stage is formed, and the page is turned while displaying based on the page data.

As described above, by changing the display manner during the continuous page feed operation in accordance with the degree of continuous page feed, for example, display contents suitable for the case where the degree of continuous page feed is small and the case where the degree of continuous page feed is large Enables continuous page feed.

For example, in the first stage, a page is turned while displaying information of each page in a rough display,
In the second stage, the page is turned while displaying only the page number, and in the third stage, a display indicating the position of the current page position during the continuous page turning operation in the entire page The page is turned by the display corresponding to each stage, such as turning the page while performing the operation.

This makes it possible to perform page feed with display contents according to the continuous page feed state. Even if high-speed continuous page feed is performed, it is possible to perform page feed in a state in which the contents can be visually confirmed easily. Information can be comfortably and efficiently searched.

Further, the degree of continuous page feed is measured by measuring the time during which continuous page feed is performed (specifically, the time during which the user continuously presses the page feed button). Because the stage is determined, it is possible to accurately reflect the continuous page feed state, and since it can be realized by providing simple components such as a counter, the configuration and processing can be simplified. can do.

FIG. 4 is a block diagram showing the internal structure of such a digital camera. CPU 31, image input processing unit 32, LCD (Liquid Crystal Display) 33, display memory (VRAM) 34, communication port 35, communication A port control unit 36, a work memory (RAM) 37, a ROM 38 in which the processing program of the present invention and other processing programs are stored, a flash memory 39, a page forward button 40 (the next page forward button 12 and the previous page forward button 13 Composed), page forward button monitoring unit 4
1. Continuous page feed monitoring unit 42, page data configuration unit 4
3, a configuration in which a real-time clock 44 and the like are provided.

The flash memory 39 corresponds to the data storage means 1 shown in FIG.
(Consisting of the next page forward button 12 and the previous page forward button 13) corresponds to the page forward unit 4 shown in FIG. 1, and the page forward button monitoring unit 41 corresponds to the page forward monitoring unit 5 shown in FIG. The continuous page feed monitoring unit 42 corresponds to the continuous page feed monitoring unit 6 shown in FIG. 1, and the page data configuration unit 43 corresponds to the page data configuration unit 2 shown in FIG.

In the digital camera thus configured, various information captured for each page is stored in the flash memory 39 as data associated with the page for each page, as described with reference to FIG. Is done.

When reading the data of each page taken in in this manner, page data is formed for each page to be opened, and for example, on the LCD 33, for example,
It is displayed as shown in FIG. The LCD 33 corresponds to the display screen 11 in FIG.

When the user wants to read the information of the page desired by the user from among a large number of fetched pages, that is, when searching for the fetched information, the user operates the page forward button 40 (next page). Page Forward Button 1
2 or the operation of continuously pressing the previous page feed button 13) is performed to continuously feed pages to obtain desired page information. Hereinafter, regarding this search processing,
This will be described in detail with reference to the configuration diagram of FIG. 4, the flowchart of FIG. 5, and a specific display example of FIG.

First, the page forward button monitor 41 monitors whether the page forward button 40 (the next page forward button 12 or the previous page forward button 13) is pressed (step s1), and presses the page forward button 40. If not, the count of the counter is cleared (count value = 0) (step s2), and the process returns to step s1.

On the other hand, if the page feed button 40 is depressed in step s1, the count of the counter is incremented by +1 and the continuous operation time of the page feed button 40 is measured (step s3). This counter is provided in the continuous page feed monitoring unit 42, and can determine the degree of continuous page feed by the user based on the count number of this counter, and creates page data according to the determination result. Then, a display based thereon is performed.

That is, the continuous page feed monitoring unit 42
The magnitude of the count value (represented by c) is compared with a predetermined value (represented by A and B, and A <B), and based on the comparison result, In this embodiment, a signal indicating the degree of continuous page feed of the first to third steps is output.

First, it is determined whether or not the count value c is smaller than A (step s4). If c <A, the continuous page feed monitor 42 indicates that the continuous page feed state is the first stage. Output a signal. As a result, the page data forming unit 43 forms page data based on the page data,
The page is turned by the first display based on the page data (step s5). The page turning by the first display is, for example, as shown in FIG. 6A, the page turning is performed by roughly displaying the contents of each page.

At the stage where the count value c is smaller than the certain value A, the user is turning pages while checking the contents of each page. In other words, to the user, it can be said that the page is being turned with an expectation that the desired page will appear several pages later. Therefore, in this first stage,
The page is not roughly turned at a high speed, but is roughly displayed as shown in FIG.

When a desired page appears in the rough display of the page turning stage, if the user stops operating the page turning button 40 at that time,
The information taken in the page is displayed on the LCD 33. In this case, if it is not a rough display but information such as that shown in FIG. 3 is taken into the page, the display contents as shown in FIG.
(LCD 33). When the page feed operation is stopped, the count value is cleared and c = 0.

On the other hand, if it is determined in step s4 that the count value c is equal to or larger than a certain value A (c ≧ A), the process proceeds to step s6 to determine whether or not the count value c is smaller than B. , C <B, the continuous page feed monitor 42 outputs a signal indicating that the continuous page feed state is the second stage. As a result, the page data forming unit 43 forms the page data based on the page data and performs the page feed by the second display based on the page data (step s7).

The continuous page feed by the second display is such that the page number is displayed for each page, for example, as shown in FIG.
At that point, based on the page number at that time,
The page numbers are displayed one after another. That is, if the page at the time when the count value c becomes equal to or more than A is, for example, the page number “5” while performing the continuous page feed operation, “page 5”, “page 6”, “7” "Page",..., Only the page number is displayed on the screen in accordance with page turning.

At the stage where the count value c is equal to or larger than A and smaller than B (A ≦ c <B), the page turning operation is performed for the user in the sense that the desired page may not appear immediately. It can be said that it is going. When the user performs a search, the desired page is also stored in the user's uncertain memory, “The page containing the information is
There was a memory such as "It was near page 0." If continuous page feed is performed based on this approximate memory and the page feed operation is stopped when "10 pages" is displayed, the information taken in the tenth page is displayed. The display at this time is a detailed display that is not rough.

When the display content of the tenth page is different from the content desired by the user, the page feed button 41 is pressed again. At this time, the steps in FIG.
When the operation of the page feed button 40 is temporarily stopped, step s2 is performed, and the process returns to step s1, so that the count value c is “0”. Therefore,
The count value c newly counted in step s3 is A
If it is smaller, the page is turned by the first display (rough display), and the user can easily find a desired page by the page display by the rough display.

That is, the display operation up to this point is as follows.
When the page is turned by the first display and the page turning operation can be continued as it is, the page is turned by the second display, and the page turning operation is stopped at an appropriate page during the page turning by the second display. When the page feed operation is started again from that page, the page is turned by the first display (rough display) for a while (while the count value c is c <A). A desired page can be easily found.

On the other hand, when the count value c of the continuous operation time of the page feed button 40 becomes equal to or more than A and further becomes equal to or more than B, the continuous page feed monitoring unit 42 sets the continuous page feed state to the third stage. Output a signal indicating that
Thereby, the page data forming unit 43 forms the page data based on the page data and the third data based on the page data.
Is performed (step s8).

The continuous page feed according to the third display means, for example, as shown in FIG. 6 (c), the page where the current page feed is located in a page in which data has been already taken. Display a page indicator that indicates For example, assuming that images have been captured from page 1 to page 100, as shown in FIG. 6 (c), from the position of the pointer P, the image is currently displayed in the current page turning operation. The position of the present page indicates that it is near 50 pages. In addition,
At this time, with respect to the entire capacity of the flash memory 39,
It may also indicate how much free space is left. In FIG. 6C, this free space is indicated by a broken line.

By performing such display, it is possible to visually know the page position in the currently performed page turning operation. To what extent the user has incorporated data into the page to be searched has been left in memory to some extent. Therefore, in high-speed page turning when a desired page does not easily come out, the page position in the current page turning operation indicates how much page position in the entire page in which information is captured. This allows the user to get an idea of a desired page, which can be used as a search aid.

That is, continuous page feed is performed based on the approximate storage of the fetched page position. For example, it is assumed that the fetched page position is near 50 pages.
When the page feed operation is stopped when the indicator P of the indicator reaches about 50 pages, the information taken in that page is displayed. The display at this time is not a rough display but a detailed display. Then, when the display content of the page is different from the content desired by the user, the user presses the page feed button again. At this time, FIG.
In the step in, the operation returns to step s1 after performing step s2 when the operation of the page feed button 40 is temporarily stopped, so that the count value is “0”. Therefore, if the count value c newly counted in step s3 is smaller than A, the page is turned by the first display (rough display). Can be easily found.

That is, the display operation up to this point is as follows.
If the page is turned by the first display and the page turning operation can be continued as it is, the page is turned by the second display and if the page turning operation can be further continued,
The page is turned according to the display content corresponding to each stage, such as the third display. Then, after the page feed operation is stopped at an appropriate page during the page feed by the third display, the page is again used as a starting point.
When the page turning operation is started, the page is turned by the first display for a while (while the count value c is c <A), so that a desired page can be easily found.

According to the embodiment described above, when the user performs a page turning operation, the operation time of the page turning button 40 is counted as to whether or not the page turning operation is a continuous page turning operation. In this way, continuous page feed is performed according to the display content according to the continuous page feed state.

Specifically, when the count value c is c <A
When the count value c satisfies A ≦ c <B, the page is turned by displaying only the page number (display of the second stage). When the count value c satisfies B ≦ c, the page is turned by a page indicator display (a third-stage display) indicating which position in the entire page the page position in the current page turning operation is.

As described above, the display contents during the continuous page feed operation are changed stepwise according to the continuous operation time of the page feed button of the user, so that even when the continuous page feed is performed at a high speed, the visual It is possible to easily check the contents, and it is possible to efficiently reach desired data, thereby enabling a comfortable search operation.

The present invention is not limited to the embodiment described above, but can be variously modified without departing from the gist of the present invention. For example, in the above-described embodiment, the first
The example in which the continuous page feed operation by the display of the third stage is performed has been described, but this is not limited to three stages, and the number of stages can be arbitrarily increased or decreased.

Also, the contents of the display at each stage are merely examples of the above-described embodiment, and the present invention is not limited to this. In short, it is sufficient that the contents of each page or the position of a page during continuous page feeding can be easily visually confirmed even when high-speed page turning is performed. Also,
For example, even when the contents of the first to third stages in the above-described embodiment are used, the order can be changed. For example, in the second stage, it is possible to perform page turning with the above-described third display content (page indicator display) and in the third stage, with the second display content (page number display). . The display contents at each stage can be set to contents suitable for the system to which the present invention is applied.

The processing program for performing the information search processing of the present invention described above can be recorded on a recording medium such as a floppy disk, an optical disk, or a hard disk. The present invention also includes the recording medium. Further, the processing program may be obtained from a network.

[0065]

As described above, the present invention monitors whether or not a page feed is a continuous feed operation, and if the page feed is a continuous feed operation, sets a plurality of continuous feed operation states. The display is divided into stages, and the display contents during the continuous feeding operation are changed and displayed for each stage. In this way, by changing the display method during the continuous page feed operation according to the degree of the continuous page feed,
For example, it is possible to perform continuous page feed by display with display contents suitable for a case where the degree of continuous feed is small and a case where the degree is large.

As a result, even if high-speed continuous page feeding is performed, continuous page feeding can be performed in a state where contents can be easily visually confirmed, so that desired information retrieval can be performed comfortably and efficiently. A digital camera with excellent usability can be obtained.

The degree of continuous page feed is determined by measuring the time during which continuous page feed is performed (specifically, the time during which the user continuously presses the page feed button). Because the stage is determined, it is possible to accurately reflect the continuous page feed state, and since it can be realized by providing simple components such as a counter, the configuration and processing can be simplified. can do.
