In addition, the photographing control unit 24, the image processing unit 25, and the input / output control unit 26 incorporate a computer and a program, and the program causes the computer to execute functions described in a flowchart described later.

Next, an operation at the time of photographing using the image photographing device 1 of the present embodiment will be described.
FIG. 4 shows the operation of the image photographing apparatus 1 during the best angle processing for searching for the best angle. In the figure, processing is performed in the following order (1) to (5).

In the following description, the case of setting the “person / animal mode” is described as an example. However, regarding operations in modes other than the “person / animal” mode, such as “building” and “thing” mode, Although the detailed operation is not shown here, the operation in the other mode is different only in the method of determining the imaging target, and the other basic parts are the same as those in the “person / animal” mode. There are various ways of determining the target in each mode. For example, using an image processing technique, a building, a person / animal, and an object are distinguished from the area occupied on the display screen and from the occupation ratio. Also, those with movement are distinguished from people and animals. In the case of a building, a plurality of shooting targets are not used.
(1) Searching for a shooting target within the display range The mode setting button 11 is operated to set the “person / animal” mode, the mode on / off button 12 is pressed, and the display screen that can be seen from the viewfinder when the best angle processing is turned on or A display screen displayed on the liquid crystal display unit is shown in 40-1. In this example, since the “human / animal” mode is set, the image capturing apparatus 1 uses the image processing technique to search for a person or an animal from those displayed in the display screen 40-1, and captures the image. Three photographing targets 41a, 41b, and 41c are searched as target photographing targets. Since the three shooting targets 41a, 41b, and 41c are searched, the number of shooting targets is set to three.

The display screen 40 that displays the best angle range may be a display screen that can be viewed from the finder or a display screen that is displayed on the liquid crystal display unit 15. It becomes a structure provided with the display part by.
(2) Determination of Range of Shooting Targets For each of the three shooting targets 41a, 41b, and 41c, minimum values x1, y1, and maximum values x2 in the X direction (vertical direction) and Y direction (horizontal direction) of each shooting target. , Y2 is obtained, and the upper right, lower right, upper left and lower left coordinates of each imaging target are obtained from this value to determine the range in which the imaging target falls. A range surrounded by dotted line frames 42a, 42b, and 42c in the display screen 40-1 is a range of each imaging target 41a, 41b, and 41c. The dotted frame 42 is not displayed on the display screen 40 trillion.
(3) Processing in the case of overlapping ranges It is checked whether there is a portion that overlaps the shooting target ranges 42a, 42b, and 42c determined in (2). In the example of FIG. 4, the ranges 42a and 42b of the imaging targets 41a and 41b overlap. When there is an overlap in the range, the one including both of these two targets is added as a new shooting target, and the entire range including the overlapping range is set as a new shooting target range 42d. This process is performed in order to process a plurality of shooting targets as a new shooting target, such as when a person is in contact with the person.

In the case of the ranges 42a and 42b, a range 42d including both the two ranges 42a and 42b is a new shooting target range, and this range 42d is additionally displayed on the display screen 40-3. In addition, since one shooting target is added, the number of shooting target objects is four.
(4) Display of the best angle range of the target shooting target If there are multiple shooting targets, target one of them, and the best range based on the range of the shooting target (best angle range) ) And display on the screen. The best angle range 43 is set so as to be within the shooting range of the photograph with the shooting target range 42 as the center.

The display screen 40-4 displays a best angle range 43a centered on the imaging target 41a. At this time, if there are a plurality of shooting targets, a mark 44 is displayed at the lower left of the screen to notify the user.
(5) Change of Target Shooting Target When the mark 44 is displayed on the display screen, there are a plurality of shooting targets, and when the user presses the target change button 13 in this state, the target shooting is performed. The target is changed, and the best angle range 43 can be changed.

  On the display screen 40-5, by pressing the target change button 13, the display is changed from the display of the best angle range 43a by the shooting target 41a to the best angle range 43b for the shooting target 41b. By operating the target change button 13, the user can change to the best angle range for the shooting target he / she wants to shoot. When the target change button 13 is further pressed in the state of the display screen 40-5, the best angle range 43 for the shooting target 41c is displayed. When the target change button 13 is further pressed, the range 42d added in (3) is displayed. The best angle range 43 centered on (the shooting target is both 41a and 41b) is displayed. Hereinafter, every time the target change button 13 is pressed, the best angle range 43 that is changed by circulating the target shooting target is displayed on the display screen 40, and the user makes one of them displayed. 1 is matched with the shooting range 5 shown in FIG. 1, for example, and then the shutter button 14 is pressed to take a picture.

FIG. 5 is a flowchart showing the entire operation processing of the image capturing apparatus 1 of the present embodiment.
In the process shown in FIG. 1, first, in step S1, the image capturing apparatus 1 sets the mode to the mode designated by the user by operating the mode setting button 11. If the user presses the mode on / off button 12, the best angle mode is turned on to start the process, and the process proceeds to step S2.

Details regarding the processing in step S1 will be described later with reference to FIG.
Step S2 realizes the best angle processing shown in FIG. 4, and searches for a shooting target, determines the best angle range for each shooting target, and displays it.

The outline of the process in step S2 is as follows.
Search for each shooting target by image processing on the displayed image (step S2a)
-Acquisition of position information of each imaging target and determination of its range (step S2b)
Determination of the best angle range for each shooting target (step S2c)
Details regarding the processing in step S2 will be described later with reference to FIG.

  The subsequent step S3 is processing when the user operates the target change button 13 to change the shooting target object when there are a plurality of shooting target objects in step S2. Thereby, the target shooting target is switched, and the best angle range displayed on the finder or the liquid crystal display unit is changed.

Details regarding the processing in step S3 will be described later with reference to FIG.
In step S4, a photographing process for pressing the shutter button 14 is performed. In this photographing process, a photographed image is captured and stored in an image memory.

Details regarding the processing in step S4 will be described later with reference to FIG.
FIG. 6 is a flowchart showing the operation in the best angle mode setting process corresponding to step S11 of FIG. The processing shown in FIG. 6 is realized by the input / output control unit 16 executing a program stored in its own internal memory.

  When the processing shown in FIG. 6 is started, what is set as the imaging target is set as the best angle mode setting in step S11. This setting is performed by the user operating the mode setting button 11, and the input / output control unit 26 sets the mode based on the setting instruction from the mode setting button 11 in the image photographing apparatus 1, and the photographing is performed. Determine the target. In this example, the modes that can be set are “person / animal”, “building”, “object”,... (Steps S2 to S5 in the figure), and the user selects these modes according to the object to be photographed. Then, the mode setting button 11 is used to instruct the setting, and the image capturing apparatus 1 performs the “person / animal” mode (step S12), the “building” mode (step S13), the “thing” mode (step S14),. An instruction setting based on the mode (step S15) and the mode instructed as the mode setting is performed on the image processing unit 25 that is in charge of the search for the shooting target.

  After performing the mode setting in steps S12 to S15, if it is detected in step S16 that the user has pressed the mode on / off button 12, the input / output control unit 26 moves the process to step S2 in FIG. To start. If it is not detected in step S16 that the mode on / off button 12 has been pressed, the process does not proceed to step S2, and the normal shooting is not performed without performing the best angle process. In this state, the shutter button 14 is pressed. Then, photographing similar to that of a normal image photographing device is performed without performing the best angle processing. Further, after the transition to the best angle mode, when the pressing of the mode on / off button 12 is detected, the best angle mode is exited and normal photographing is performed.

  In order to reset the best angle range, the mode on / off button 12 is pressed to exit the best angle mode, and then the mode on / off button 12 is pressed again to start the processing again from the search for the shooting target. The Thereby, after the best angle range is displayed, it is possible to cope with a situation in which the shooting state is changed and an appropriate screen display is not performed.

  FIG. 7 is a flowchart of processing for searching for a shooting target and displaying the best angle range, corresponding to step S2 of FIG. Note that the processing shown in the figure is realized by the input / output control unit 16 executing a program stored in its own internal memory using the internal memory as a work memory.

  When the process shown in FIG. 6 is started, first, in step S21, the input / output control unit 26 displays a person / animal or the like in the display screen displayed from the viewfinder or the liquid crystal display unit with respect to the image processing unit 25. The image processing is performed on the image data for the display image in the image processing memory 29 to search whether there is a shooting target.

  In step S22, the input / output control unit 26 counts the number of imaging targets searched by the image processing unit 25, and stores the number in a variable (CNT) 71 in its own internal memory. In this process, it is assumed that the number of shooting targets is 1 or more. If the number of shooting targets is 0, this process ends.

  In step S23, the input / output control unit 26 initializes the variable (n) used for loop processing by setting 1 to it. In step S24, it is checked whether the variable (n) is within the number of imaging targets (n <= CNT) in the variable (CNT) 71. If the number is within the number of imaging targets (CNT) (step S24, YES), In step S25, the upper, lower, right and left coordinates of the nth imaging target are acquired, and a range surrounded by the acquired coordinates is stored in the internal memory as coordinate information 72. In step S26, 1 is added to the variable (n), and then the process returns to step S24.

Thereafter, the processing of steps S24 to S26 is repeated until the variable (n) exceeds the number of shooting targets, and the range of each shooting target is obtained.
If the variable (n) exceeds the number of imaging targets (CNT) in step S24 (step S24, NO), the coordinate information 72 of each imaging target obtained in the process of step S25 is checked as step S27. Check if the shooting target ranges overlap.

  As a result, when there is an overlap in the range of each imaging target (step S28, YES), the entire range including the overlapped range is obtained as step S29, and the coordinate information 72 is added to the memory as the new imaging target range. . If there are a plurality of overlaps, the process in step S29 is performed for all the overlaps. In step S30, the number newly set as the imaging target in step S29 is added to the variable (CNT). In step S28, if there is no overlap (NO in step S28), the processing in steps S31 and after is performed by skipping the processing in steps S29 and S30.

  In step S31, the input / output control unit 26 acquires the coordinate information 72 of the first imaging target from the coordinate information 72 obtained in the processing so far and stored in the internal memory, and the imaging range centered on that range. A coordinate range (best angle range) 73 having the same size as is determined and stored in the internal memory. This best angle range is the angle that seems to be the best around the shooting target.

  In step S32, the input / output control unit 26 stores the shooting target process number currently being processed in a variable (T_NO) 74 in the internal memory. Here, 1 is stored. This value represents the number of the shooting target that is the current target when there are a plurality of shooting targets, and is used during the shooting target changing process described later.

In step S33, the determined best angle range is displayed on the display screen. The display of the best angle range is made distinguishable using lines, colors, etc. different from the shooting range.
Finally, in step S34, the image data of the image in the best angle range is stored in the best angle memory 31, and the present process is terminated.

In this way, by performing the processing as shown in FIG. 7, it is possible to search for a shooting target, determine the best angle range of the shooting target, and display it.
FIG. 8 is a flowchart corresponding to step S3 of FIG. 5 and showing a process of changing the target shooting target displaying the best angle range, which is performed when the user presses the target change button 13. is there. This process is effective when there are a plurality of imaging targets.

The processing shown in FIG. 8 is also realized by the input / output control unit 16 executing a program stored in its own internal memory using the internal memory as a work memory.
In this process, first, in step S41, the target number (T_NO) 74 of the imaging target currently being displayed is acquired from the internal memory. When this processing is performed, this value is 1.

  Next, as step S42, it is checked whether the acquired target number (T_NO) of the shooting target is smaller than the number of shooting targets (CNT) ((T_NO) + 1 ≦ (CNT)). Since there is a next shooting target object, the shooting target processing number (T_NO) is incremented by one in step S43. If the target number (variable (T_NO) +1) acquired in step S42 is not less than the number of target targets (CNT) and there is no target target (NO in step S42), the target is set as step S44. The object number (T_NO) is returned to the top number, that is, the initial value of 1.

  In step S45, the input / output control unit 26 acquires, from the internal memory, the coordinate information 72 of the shooting target indicated by the shooting target target number (T_NO) determined in the preprocessing. In step S46, the best angle range is determined based on the coordinate information 72 acquired in step S45, and the determined best angle range information 73 is stored in the internal memory, as in step S31 of FIG.

  In step S47, the determined best angle range is displayed on the display screen. In step S48, the image data of the image in the best angle range is stored in the best angle memory 31, and the process is terminated.

  In this way, by performing the processing shown in FIG. 8, every time the user presses the target change button 13, the target shooting target is changed, and the best angle range of the shooting target is displayed on the display screen. I can do it.

  FIG. 9 is a flowchart showing processing at the time of photographing corresponding to step S4 of FIG. The process shown in FIG. 6 is also realized by the input / output control unit 16 executing a program stored in its own internal memory.

  In this process, the input / output control unit 26 captures the portion of the imaging range of the image data of the image displayed on the display screen stored in the image processing memory in step S51, and the best angle memory 31 in steps S34 and S48. The image data in the best angle range stored inside is compared. As a result, if the two are almost the same (step S52, YES), the color of the frame for displaying the best angle range is changed or blinked or the user is informed by voice or the voice is notified as a step S53. (Step S52, NO), the process of step S53 is skipped.

  In this state, if the input / output control unit 26 does not detect that the user has pressed the shutter button 14 (step S54, NO), the process returns to step S51. If it is detected in step S54 that the shutter button 14 has been pressed (YES in step S54), in step S55, the input / output control unit 26 instructs the imaging control unit 24 to perform shooting, and the imaging control unit 24 The processing unit 25 corrects the output data from the A / D converter 23 with parameters set such as white balance, and then performs compression to generate image data, which is stored in the image processing memory 29.

By performing the processing shown in FIG. 9, it is possible to perform photographing at an angle considered to be the best.
In addition to the above configuration example, the state (color, shape, etc.) of the shooting target is stored in the memory, and if it is determined from the information that the shooting target has disappeared from within the display range, the shooting state has changed. The reprocessing may be performed again from the search of the shooting target. As a result, after the best angle range is displayed on the display screen, the best angle range can be selected, for example, when the shooting target moves and the range changes, or when the shooting state changes due to a new person entering the display range. If the situation changes after being derived, it can be dealt with.

  In the present embodiment, the search of the shooting target is performed by image processing. However, another method, for example, a configuration in which a sensor is provided in the image shooting apparatus and the shooting target is searched based on information from the sensor.

  Furthermore, the best angle range of the target shooting target may be automatically displayed at the center on the display screen. Further, enlargement display and enlargement photographing may be performed around the photographing target so that the range of the photographing target is displayed at the maximum on the display screen.
