[Analog clock imaging processing]
FIG. 2 shows an analog clock including a minute hand, hour hand, and dial, which is executed by the digital camera 10 in a shooting mode, as a subject, and the captured clock image is converted into an image including the minute hand and hour hand and an image including a dial. It is a flowchart which shows the analog timepiece imaging | photography process divided | stored and memorize | stored. FIG. 3 is a diagram illustrating a state before detection of the minute hand and hour hand of the analog timepiece in the analog timepiece imaging process. FIG. 4 is a diagram illustrating a state in which the minute hand and hour hand of the analog clock are being detected in the analog clock imaging process performed in the shooting mode.

  When the photographing unit is selected by operating the input unit 50 and an analog clock imaging process is instructed, the CPU 20 reads a program for executing the process of the flowchart shown in FIG. The CPU 20 executes various processes in the flowchart shown in FIG. 2 according to this program.

  First, with reference to FIG. 2, the imaging process executed in the imaging mode controlled by the CPU 20 will be described.

  First, the CPU 20 performs an analog clock imaging process (step S11). In the analog clock imaging process, an analog clock placed in front of the image sensor 30 is imaged, and an image including the minute hand 3, hour hand 4 and dial 5 constituting the analog clock is acquired. Here, the dial 5 may include a case part of the analog timepiece or a metallic decorative member such as a bezel attached to the outside of the case part.

  In this case, the analog clock that is the subject of the subject need not necessarily be a real analog clock that is moving, and may be a clock that has a minute hand, an hour hand, and a dial. That is, it may be a photo or catalog of an analog clock or a toy clock. The image acquired in the analog clock image processing is stored in the image RAM 40.

In the analog clock imaging process, it is preferable to acquire images including the minute hand 3, hour hand 4, and dial 5 constituting the analog clock at least twice, preferably a plurality of times at different times. In other words, the presence of the minute hand 3 and the hour hand 4 may obscure several characters 8 for displaying the time described on the dial 5 behind it and the pattern of the dial 5, so the minute hand 3 and the hour hand At the time when the position of the dial 5 to be hidden differs from that at 4, the image is taken at least twice by the analog clock imaging process, and at least two images thus taken are stored in the image RAM 40.
In addition, when the analog clock imaging process is required at least twice, a message that the second analog clock imaging process needs to be performed again at a different time after the first analog clock imaging process is sent to the user. You may make it alert | report by a sound, a liquid crystal display, or an email.

  Further, even when two analog clock photographing processes are required, it can be ended only by one analog clock photographing process by the user's selection. In this case, the user may select and use a favorite dial from a plurality of dials prepared in advance.

  Next, the image acquisition unit 70 generates an image obtained by dividing the portion of the dial 5 of the analog timepiece and the hands composed of the minute hand 3 and the hour hand 4 from the image captured by the instruction of the CPU 20 ( Step S12). In the present embodiment, the image acquisition unit 70 includes an image stored in the image RAM 40, an image of a hand portion constituted by the minute hand 3 and the hour hand 4 of the analog clock, and a minute hand 3 and the hour hand 4. The image is divided into the image of the portion of the dial 5 from which the image of the needle portion is removed.

  Further, the CPU 20 may determine whether or not all the images of the minute hand 3 and the hour hand 4 have been extracted by collating with the hour / minute hand detection data stored in the image RAM 40. Here, if it is determined in step S11 that any one of the minute hand 3, hour hand 4, and dial 5 has been captured, a message indicating that it is necessary to perform analog clock imaging processing again at a different time. May be notified to the user by sound, liquid crystal display or e-mail. And when the user did not follow this notification and did not perform the analog clock photographing process again, the user selected and acquired the favorite minute hand and hour hand from the plurality of minute hands and hour hands prepared in advance. It can also be used as a minute or hour hand.

  At this time, in the first analog clock imaging process, if the CPU 20 determines that the color of the dial 5 is a single color or a single pattern, it may not be performed a plurality of times. Even if the minute hand 3 and hour hand 4 have been removed, for example, by filling the color and pattern of the dial 5 behind the minute hand 3 and hour hand 4 by performing complementary processing based on the surrounding color and pattern, Images of the hand 3, hour hand 4, and dial 5 may be generated.

  In addition, although the analog timepiece to be imaged is described as a timepiece having a minute hand, an hour hand, and a dial, it is not limited to this. That is, it may be a clock having only the minute hand, only the hour hand, or only the dial, or other catalog images. In addition, when there is no image of the minute hand, hour hand or dial in the acquired image, the user selects a desired image from the image of the minute hand, hour hand or dial prepared in advance as an alternative image, An image of an hour hand or a dial may be used.

  Next, the CPU 20 stores the dial face image and the hand image thus extracted in association with each other in the divided image RAM 80 (step S13). The dial image is an image including the dial of an analog clock among the divided images, and the hand image is an image including the minute hand and the hour hand of the analog clock among the divided images. When this process ends, the imaging process ends.

In this imaging process, display examples displayed on the liquid crystal display unit 100 are shown in FIGS.
When the analog clock imaging process in the imaging process is started in step S11, the CPU 20 causes the liquid crystal display unit 100 to display the subject of the imaging process, that is, the center of the target analog clock 1 as shown in FIG. The photographing screen frame 2 for adjusting the size is displayed.
In this state, when the analog timepiece 1 is placed in the photographing screen frame 2, as shown in FIG. 4, the minute hand detection frame 6 for detecting the minute hand 3 of the analog timepiece 1 and the hour hand detection frame for detecting the hour hand 4. 7 is displayed. In step S12, the CPU 20 compares the hour hand / minute hand detection data stored in the image RAM 40 with the clock / minute hand detector 60, and the minute hand 3 and hour hand stored in the minute hand detection frame 6 and hour hand detection frame 7. 4 is detected.

  Here, the CPU 20 may detect the minute hand 3 and the hour hand 4 by, for example, image recognition processing. For example, the CPU 20 calculates the feature data of the photographed subject (recognition of the contour and feature points of the subject and their positional relationship etc., and numerical values obtained by digitizing them) based on the captured image data. Then, by comparing with the characteristic data of each type of hour hand / minute hand registered in advance in the hour / minute hand detection data, the hour / minute hand portion is specified from the image data of the imaged subject. At this time, from the captured image data, the portion with the highest degree of coincidence is detected as the image data of the hour hand / minute hand with respect to the characteristic data of each type of hour hand / minute hand registered in the hour / minute hand detection data. It may be. Alternatively, the same analog clock may be photographed a plurality of times at different times, the images may be compared and collated, and the hour / minute hands may be detected from an area where the change is large.

[Time display processing]
FIG. 5 is a flowchart showing time display processing executed by the digital camera 10 in the time display mode. FIG. 6 is a diagram illustrating a display example of an image synthesized by the time display process.

  When the user operates the input unit 50 to select the time display mode, the CPU 20 reads a program for executing the processing of the flowchart shown in FIG. The CPU 20 executes various processes in the flowchart shown in FIG. 5 according to this program.

  First, with reference to FIG. 5, the time display process performed in the time display mode by control of CPU20 is demonstrated.

First, the CPU 20 selects a clock image (original image) according to a user instruction (step S21). In this process, the CPU 20 displays one or a plurality of divided dial images and needle images stored in association with the divided image RAM 80 on the liquid crystal display unit 100, and the dial image and the needle image designated by the user. Select.
Note that the dial image and the hand image may be selected from images extracted from the same analog clock image stored in the divided image RAM 80, but the present invention is not limited to this. For example, the dial image and the hand image may be selected from images of different analog clocks.

Next, the CPU 20 acquires the time measured by the time measuring unit 85 as the current time (step S22).
Next, the image synthesizing unit 90 creates a synthesized image by synthesizing the corresponding dial face image and the hand image so as to become an image of the analog clock indicating the acquired current time in accordance with an instruction of the CPU 20 (step S23). . In this process, the image of the minute hand selected in step S21 and the image of the hour hand are superimposed on the dial image selected in step S21 so that the current time measured by the CPU 20 is indicated. At this time, the hour hand and the minute hand are synthesized so as to rotate according to the actual time around the center of the screen, that is, the center of the analog clock taken.

  Next, the CPU 20 displays the composite image thus created on the liquid crystal display unit 100 (step S24).

Next, the CPU 20 determines whether or not there is a display end instruction (step S25). That is, in this process, it is determined whether or not a time display end instruction has been issued by the user operating the input unit 50 to select a mode other than the time display mode such as the shooting mode. When it is determined that there is no display end instruction, the CPU 20 returns to the process of step S22, whereas when it is determined that there is a display end instruction, the time display process is ended.
Therefore, while the time display mode is selected by the user, the processes in steps S22 to S24 are sequentially repeated, and the liquid crystal display unit 100 acquires the current time so as to display the current time. Then, a process of synthesizing images to create a composite image and a process of displaying the composite image are sequentially repeated. The program stored in the program ROM is rotated in accordance with the actual time around the center of the screen, that is, the center of the imaged analog clock, with the hour hand and minute hand detected at the time of photographing in steps S23 and S24. Make a program like this. As a result, it is possible to reproduce a picture of a clock whose hands move according to time.

In this time display process, FIG. 6 shows a display example displayed on the liquid crystal display unit 100 when the current time is 11:30.
As shown in FIG. 6, when the composite image is displayed in the time display process, the liquid crystal display unit 100 displays an image of the synthesized dial 5a constituting the analog clock 1a and an image of the dial 5a. The selected minute hand 3a and hour hand 4a are displayed.
On the dial 5a, several characters 8a for displaying the current time are displayed. This number character 8a is not displayed in principle when the original analog timepiece 1 does not have the number character 8a. However, in the case of a dial having no number character 8a, the number character 8a prepared in advance is not displayed. The user may select several desired characters 8a and synthesize them on the image of the dial 5a.
While the time display mode is selected by the user, the minute hand 3a and the hour hand 4a are displayed on the liquid crystal display unit 100 so as to display the current time.

As described above, in the embodiment of the present invention, an image including the minute hand 3, the hour hand 4 and the dial 5 is acquired, and the acquired image is an image of a hand portion including the minute hand 3 and the hour hand 4. The image of the dial 5 is divided into the image of the dial 5 from which the image of the hand portion has been removed, and the minute hand 3 and the hour hand 4 divided by the image acquisition unit 70 to indicate the current time on the image of the divided dial 5. The images are combined to create a combined image, and this combined image is displayed on the liquid crystal display unit 100.
For this reason, the minute hand and hour hand can be displayed on the acquired analog clock face image to indicate the current time, so the user can capture and acquire an image of their favorite analog clock with a digital camera. You can display the analog clock as if it were actually moving.
Therefore, even if you are interested in an analog watch that you are not interested in because of its high price, the current time is displayed by effectively using images such as the hour hand, minute hand, and dial of the analog watch. This can enhance the interest of the user.

Further, the images of the minute hand, the hour hand, and the dial face to be acquired may be not only a real analog clock that is actually moving, but also a photograph of an analog clock listed in a catalog or a toy clock.
As a result, for example, even an antique clock that is no longer moving, or a photo or picture of it, it can be displayed as if it is actually moving by utilizing the minute hand, hour hand and dial. it can.
Therefore, in the past, instead of a digital display such as that displayed on a 7-segment display, or an analog-like display clock formed simply by a simple pattern or pattern created by a program, an actual minute hand, hour hand Alternatively, the user's interest can be enhanced by using the dial to display the current time.

Further, in the present embodiment, while the input unit 50 is operated and the time display mode is selected, the time measurement process by the CPU 20, the composition process by the image composition unit 90, and the liquid crystal display unit 100 by the CPU 20. The display process is sequentially performed.
Therefore, the current time is continuously displayed on the liquid crystal display unit 100 unless the time display mode is ended by the user operating the input unit 50. Therefore, the user can select the time display mode and use it as an analog clock that keeps displaying the current time every moment, like an actual analog clock.

  In the present embodiment, a plurality of images including the minute hand 3, the hour hand 4, and the dial 5 are acquired at different times, and the acquired plurality of images are images of a hand portion including the minute hand 3 and the hour hand 4. And the image of the dial 5 from which the image of the hand portion has been removed, respectively, and one dial is generated from the dial images divided at different times, and the generated dial An image of the minute hand 3 and the hour hand 4 divided by the image acquisition unit 70 so as to indicate the current time is synthesized on the image of, to create a synthesized image, and this synthesized image is displayed on the liquid crystal display unit 100.

  For this reason, even when the pattern of the dial 5 behind it is hidden by the presence of the minute hand 3 and the hour hand 4 at the time of acquiring the first image, at the time of acquiring the second and subsequent images. The pattern of the dial 5 can be acquired. As a result, by synthesizing the dial images acquired at the first time and the second and subsequent times, the parts where the dial pattern is hidden are complemented to each other, and one complete pattern dial image is obtained. Can be generated. For this reason, the user can display the minute hand and the hour hand so as to indicate the current time on the dial having the same pattern or pattern as the original analog timepiece. Therefore, it is possible to enhance the interest of the user by restoring the original analog clock pattern almost completely and displaying the current time.

  In the above, the time display apparatus of various embodiment was demonstrated.
