Description

The present invention relates to a photographing device, a display control method in the photographing device, and a computer program used to control the photographing device.

In order to assist the user in shooting using the photographing device, a photographing device that displays information (state information) regarding the state of the photographing device on the display screen of the photographing device has been proposed. The state of the photographing device is, for example, an exposure condition such as an inclination (horizontality, elevation / depression angle) of the photographing device, a shutter speed, an aperture value, and the like in an imaging process using the photographing device. The user can easily capture a desired subject image by operating the photographing device while checking the state information displayed on the display screen. As such a photographing device, Patent Document 1 discloses a photographing device that displays tilt information of the photographing device.

In the photographing apparatus described in Patent Document 1, an inclination guide corresponding to the inclination of the photographing apparatus is displayed on the display screen. The user can shoot a subject image with an unintended tilt suppressed by operating the shooting device while checking the tilt guide.

Japanese Unexamined Patent Publication No. 2008-011240

By the way, some photographing devices have a function of automatically adjusting the focal length and the exposure condition. When the shutter button is pressed halfway, this type of imaging device changes from the imaging standby state to the recording ready state, and automatically adjusts the focal length and exposure conditions. The user confirms the adjustment result of the focal length and the exposure condition on the display screen, and further presses the shutter button to execute the recording process of the subject image under the adjusted focal length and the exposure condition. Therefore, when the photographing device is in the recording ready state, it is desirable that the subject image or the subject in the focused state among the subject images is displayed on the display screen so as to be easily visible.

However, in the photographing apparatus described in Patent Document 1, once the tilt guide is displayed, the tilt guide continues to be displayed until the shutter button is pressed and the subject image is recorded. Therefore, when the photographing device is in the recording ready state, there is a problem that it is difficult for the user to visually recognize the subject in the focused state on the display screen.

The present invention has been made in view of the above circumstances, and an object of the present invention is to allow a user, for example, a subject image or a subject in focus, when the photographing device switches from a shooting standby state to a recording ready state. It is an object of the present invention to provide a photographing device capable of continuously confirming the state information of the photographing device, a display control method in the photographing device, and a computer program used for controlling the photographing device without making it difficult to visually recognize the main information.

It is provided with a preparatory operation member for receiving. The state information display means controls the display form of the state information displayed on the display unit in response to the reception of the preparation operation by the preparation operation member.

According to the present embodiment, the display form of the state information displayed on the display unit is changed between before the photographing apparatus is in the recording ready state (shooting standby state) and when the photographing apparatus is in the recording ready state. As a result, the state information is displayed in a form suitable for each state, so that it becomes difficult for the user to see the main information (for example, the subject in the focused state) when the photographing device is in the recording ready state. It is possible to check the status information of the photographing device while preventing it from being stored.

The recording preparation includes the focus adjustment of the lens, and the focus mark display means for displaying the focus mark on the display unit by superimposing the focus mark on the subject detected as being in focus as a result of the focus adjustment. May be further provided. In this case, the state information display means controls the display form of the state information so as to prevent the focusing mark and the state information from being superimposed.

The state detection unit may include a tilt detection unit that detects the tilt of the photographing device. In this case, the state information display means superimposes the tilt information detected by the tilt detection unit on the subject image and displays it on the display unit.

The photographing device captures a recording operation member that receives a recording operation instructing the recording unit to record the subject image, and a subject image based on the inclination detected by the inclination detection unit in response to the reception of the recording operation by the recording operation member. Further, a horizontal correction means for correcting so as to be horizontal may be provided. In this case, the state information display means adjusts the tilt information displayed on the display unit to the tilt that can be corrected by the horizontal correction means from the tilt detected by the tilt detection unit in response to the reception of the preparation operation by the preparation operation member. The display form of the state information is controlled by displaying the tilt information based on the deducted value on the display unit.

The state detection unit may further include a brightness detection unit that detects the brightness of the subject image, and further includes an exposure determination unit that determines exposure information based on the brightness detected by the brightness detection unit. In this case, the state information display means displays the exposure information as state information on the display unit.

The state information display means may change any one of the display positions, shapes, and colors of the state information to be displayed on the display unit, or a combination thereof, in response to the reception of the preparation operation by the preparation operation member.

(First Embodiment)
Hereinafter, the photographing apparatus according to the first embodiment of the present invention will be described with reference to the drawings. Hereinafter, a digital single-lens reflex camera will be described as an embodiment of the present invention. The photographing device is not limited to a digital single-lens reflex camera, for example, a mirrorless single-lens camera, a compact digital camera, a video camera, a camcorder, a tablet terminal, a PHS (Personal Handy phone System), a smartphone, a feature phone, a portable game machine, etc. , It may be replaced with another form of device having a photographing function.

FIG. 1 is a block diagram showing the configuration of the photographing apparatus 1 of the present embodiment. As shown in FIG. 1, the image sensor 1 includes a CPU (Central Processing Unit) 100, an operation unit 102, a lens drive circuit 103, an aperture / shutter drive circuit 104, an image sensor 106, an aperture 108, a shutter 110, and a tilt detection unit. It includes 111, a solid-state image sensor 112, a signal processing circuit 114, an image processing engine 116, a buffer memory 118, a card interface 120, an LCD (Liquid Crystal Display) control circuit 122, an LCD 124, and a ROM (Read Only Memory) 126.

The operation unit 102 includes various switches necessary for the user to operate the photographing device 1, such as a power switch, a shutter button, and a photographing mode switch. When the power switch is pressed by the user, power is supplied from the battery (not shown) to various circuits of the photographing device 1 through the power line. After supplying power, the CPU 100 accesses the ROM 126, reads a control program, loads it into a work area (not shown), and executes the loaded control program to control the entire photographing apparatus 1.

The luminous flux from the subject passes through the photographing lens 106, the aperture 108, and the shutter 110, and is received by the light receiving surface of the solid-state image sensor 112. The solid-state image sensor 112 is a single-plate color CCD (Charge Coupled Device) image sensor having a Bayer-type pixel arrangement. The solid-state image sensor 112 accumulates the optical image formed by each pixel on the light receiving surface as an electric charge according to the amount of light, and generates R (Red), G (Green), and B (Blue) image signals. Output. The solid-state image sensor 112 is not limited to the CCD image sensor, and may be replaced with a CMOS (Complementary Metal Oxide Semiconductor) image sensor or other types of image sensors. The solid-state image sensor 112 may also be equipped with a complementary color filter.

The signal processing circuit 114 performs predetermined signal processing such as clamping and demosaicing on the image signal input from the solid-state image sensor 112, and outputs the image signal to the image processing engine 116. The image processing engine 116 performs predetermined signal processing such as matrix calculation, Y / C separation, and white balance on the image signal input from the signal processing circuit 114 to generate a luminance signal Y, a color difference signal Cb, and Cr. .. Further, the image processing engine 116 buffers the generated luminance signals Y, color difference signals Cb, and Cr in a frame memory (not shown) in frame units. The image processing engine 116 sweeps out the buffered signal from each frame memory at a predetermined timing, converts it into a video signal in a predetermined format, and outputs the buffered signal to the LCD control circuit 122. The buffer memory 118 is used as a temporary storage location for processing data when the processing by the image processing engine 116 is executed. The LCD control circuit 122 modulates and controls the LCD 124 based on the image signal input from the image processing engine 116. As a result, the image of the subject (subject image) is displayed on the LCD 124. The user can visually recognize a real-time through image (live view) of the subject through the LCD 124.

When the shutter button is half-pressed while the through image is displayed on the LCD 124 (shooting standby state), the shooting device 1 changes from the shooting standby state to the recording ready state. When the exposure condition of the photographing device 1 is set to be automatically adjusted, the CPU 100 performs AE (Automatic Exposure) control in the recording preparation state. In AE control, exposure conditions (shutter speed, aperture value, ISO (International Organization for Standardization) sensitivity) during recording processing, which will be described later, are determined so that proper exposure can be obtained based on the image signal input from the solid-state image sensor 112. Will be done. The exposure condition is determined based on the AE function specified by the shooting mode switch, such as program AE, shutter speed priority AE, and aperture priority AE. Since the configuration and control of this type of AE are well known, detailed description thereof will be omitted here.

Further, when the focus of the photographing apparatus 1 is set to be automatically adjusted, the CPU 100 performs AF (Autofocus) control in the recording preparation state. In the AF control, the lens 106 is driven and controlled via the lens drive circuit 103 so that the entire or part of the subject image is in focus. An active method, a phase difference detection method, a contrast detection method, and the like are applied to the AF control. Further, the AF mode includes a central one-point distance measurement mode using a central one-point distance measurement area, a multi-point distance measurement mode using a plurality of distance measurement areas, and the like. When the AF control is performed, on the LCD 124, an in-focus area (in focus) or an in-focus mark indicating the subject is displayed superimposed on the subject image. Since the configuration and control of this type of AF are well known, detailed description thereof will be omitted here.

When the shutter button is further pressed from the half-pressed state and then fully pressed, the CPU 100 executes the recording process of the subject image. In the recording process, the subject image is captured at the exposure condition (or manually set exposure condition) determined by the AE control and the position of the lens 106 adjusted by the AF control, and the captured image data is stored in the image processing engine 116. Will be generated. The generated photographed image data is compressed in a predetermined format such as JPEG (Joint Photographic Experts Group), and is stored in a memory card 200 (or an internal memory (not shown) provided in the photographing apparatus 1 via the card interface 120). Recorded. Further, the storage format of the captured image data is not limited to the JPEG format, and may be, for example, the RAW format.

When the user performs a reproduction operation of the captured image data on the operation unit 102, the image processing engine 116 reads the captured image data specified by the operation from the memory card 200 or the built-in memory and converts the captured image data into an image signal in a predetermined format. It is converted and output to the LCD control circuit 122. The LCD control circuit 122 modulates and controls the LCD 124 based on the image signal input from the image processing engine 116, so that the captured image of the subject is displayed on the LCD 124.

The tilt detection unit 111 has a three-axis acceleration sensor and is mounted in the photographing device 1. The CPU 100 calculates the acceleration of the photographing device 1 and the direction of the acceleration based on the acceleration detected and output by the tilt detecting unit 111. Based on the acceleration and the direction of the acceleration, the inclination (posture (roll) and elevation / depression angle (pitch or tilt) around the optical axis) of the photographing device 1 is calculated. The posture of the photographing device 1 represents an inclination (horizontal degree) of the photographing device 1 with respect to the horizontal direction. The calculated tilt is transmitted to the image processing engine 116. The image processing engine 116 generates a guide signal based on the received tilt. The guide signal is transmitted to the LCD 124 via the LCD control circuit 122 and displayed on the LCD 124 as a tilt guide. The tilt guide displayed on the LCD 124 includes a horizontal guide based on horizontality and an elevation / depression guide based on the elevation / depression angle.

Next, control of the display form of the tilt guide displayed on the LCD 124 will be described with reference to a flowchart. FIG. 2 is a flowchart relating to control of the display form of the tilt guide among the processes executed by the photographing apparatus 1. The flowchart shown in FIG. 2 may be executed as a subroutine that operates in parallel with the main flow of the photographing device 1.

In the process step S1, it is determined by the CPU 100 whether or not the operation unit 102 has been operated to end the display of the through image. When an operation for instructing the operation unit 102 to call the menu display or execute the recording process is input and a process for displaying a screen other than the through image is performed on the LCD 124, an operation for ending the display of the through image is performed. It is determined that the device has been damaged (S1: YES), and the control flow of the display form of the tilt guide ends. On the other hand, when it is determined that the operation for ending the display of the through image has not been performed (S1: NO), the process proceeds to the process step S2.

In the process step S2, it is determined by the CPU 100 whether or not the photographing device 1 is set to display the tilt guide while the through image is displayed on the LCD 124 (shooting standby state). Whether or not the photographing device 1 is set to display the tilt guide may be set as a default setting when the power of the photographing device 1 is turned on, and it depends on the operation of the operation unit 102 by the user. It may be switchable. If it is determined in the process step S2 that the tilt guide is not displayed (S2: NO), a through image is displayed on the LCD 124 with the tilt guide hidden (S3), the process returns to the process step S1.

If it is determined in the process step S2 that the tilt guide is set to be displayed (S2: YES), the process proceeds to the next process step S4. In the process step S4, the tilt guide is superimposed on the through image of the subject image and displayed on the LCD 124. Whether to display both the horizontal guide and the elevation / depression guide as the tilt guide, to display one of them, or to hide both of them can be changed according to the user operation to the operation unit 102. Hereinafter, a case will be described in which the photographing device 1 is set so that only the horizontal guide is displayed as the tilt guide and the elevation / depression guide is hidden. Further, in the present specification, when the term "horizontal guide" is used without any particular reference numeral, the horizontal guides of various forms are comprehensively indicated, and when the display form and the display position are separately described, the horizontal guides are shown horizontally. It shall be indicated by adding a reference such as a guide 20a (see FIG. 3).

FIG. 3 is a diagram showing an example of displaying a horizontal guide on the LCD 124. In the following description, it is assumed that the horizontal guide displayed in the processing step S4 has the form shown in FIG. As shown in FIG. 3, the through image 10 of the subject image is displayed on the LCD 124, and the horizontal guide 20a indicating the horizontality of the photographing device 1 is superimposed and displayed on the through image 10.

As shown in FIG. 3, the horizontal guide 20a has a circular shape, and the reference lines Ha and Va of the cross are displayed in the circle. Further, on the horizontal guide 20a, a tilt line La representing the horizontal direction (direction orthogonal to the gravity direction) is displayed tilted with respect to the reference line Ha in the horizontal direction based on the horizontality calculated by the CPU 100. Therefore, for example, when the photographing device 1 rolls counterclockwise by a predetermined angle while the user is looking straight ahead at the LCD 124 (when the LCD 124 goes down to the left and goes up to the right), the tilt line La is horizontal. It is displayed in a state of being rotated clockwise by a predetermined angle with respect to the reference line Ha of the direction. By visually recognizing the angle of the tilt line La with respect to the reference line Ha, the user can recognize in which direction and how much the photographing device 1 is tilted (how much it rolls around the optical axis). .. It is not necessary that the inclination of the inclination line La on the LCD 124 and the inclination of the actual photographing device 1 match. For example, in order to make it easier for the user to recognize the inclination of the photographing device 1, the inclination line La may be displayed with an inclination larger than the actual inclination of the photographing device 1.

When the photographing device 1 is in the photographing standby state, it is desirable that the horizontal guide 20a is displayed near the center of the LCD 124. When the user is operating the photographing device 1 while looking at the LCD 124, it is considered that the user feels that the center (optical axis) of the lens 106 is substantially aligned with the center of the LCD 124. Therefore, by arranging the horizontal guide 20a near the center of the LCD 124, it becomes easy to realize that the movement of the tilt line La of the horizontal guide 20a is the actual tilt of the photographing device 1. This makes it easier for the user to adjust the horizontality of the photographing device 1 while looking at the horizontal guide 20a.

In the process step S5, the CPU 100 determines whether or not the shutter button is half-pressed and the photographing device 1 is in the recording ready state. When it is determined that the photographing device 1 is not in the recording preparation state (in the shooting standby state) (S5: NO), the process returns to the processing step S1. When it is determined that the photographing device 1 is in the recording ready state (S5: YES), the process proceeds to the process step S6, and the CPU 100 executes the process of changing the display form of the tilt guide (horizontal guide).

The flowchart shown in FIG. 4 represents a process of changing the display form of the tilt guide in the process step S6. As described above, when the shutter button is half-pressed and the photographing apparatus 1 is in the recording ready state, the AF process is executed and the focusing mark is displayed on the LCD 124. In the process step S11, before the focusing mark is displayed on the LCD 124, the position where the horizontal guide 20a is displayed and the position where the focusing mark is displayed when the photographing device 1 is in the photographing standby state by the CPU 100 It is determined whether or not overlaps with.

When it is determined that the position where the horizontal guide 20a is displayed and the position where the focus mark is displayed overlap (S11: YES), the horizontal guide is shown in FIG. 3 so as not to overlap with the focus mark. The display form is changed and displayed from the horizontal guide 20a during the shooting standby (S12). The horizontal guide 20b shown in FIG. 5 is an example of displaying the horizontal guide whose display form has been changed in the processing step S12 on the LCD 124. As shown in FIG. 5, on the through image 10, the focusing mark 30 is displayed so as to be superimposed on the position (subject) of the subject image that is in the focusing state by the AF control. The horizontal guide 20b has a rectangular shape and is displayed below the LCD 124 so as not to overlap with the focusing mark 30. The horizontal guide 20b whose display form has been changed has a rectangular shape, and a reference line Vb is displayed in the center. Further, on the horizontal guide 20b, a bar Bb is displayed so as to extend in the left-right direction from the central reference line Vb according to the horizontality calculated by the CPU 100.

The position and number of the subjects in the focused state in the subject image change depending on the shooting conditions such as the state of the lens 106 of the shooting device 1 and the positional relationship between the shooting device 1 and the subject. Further, the number of the focusing marks 30 displayed varies depending on the specifications and settings of the photographing device 1. Therefore, depending on the shooting conditions and the setting of the shooting device 1, the focusing mark 30 may be displayed at the position where the horizontal guide 20a was displayed during the shooting standby. In this case, the focusing mark 30 and the horizontal guide are overlapped with each other, and there arises a problem that either or both of the focusing mark 30 and the horizontal guide are difficult to see. Therefore, in the present embodiment, when it is determined that the position where the horizontal guide 20a is displayed and the position where the focusing mark is displayed overlap, the display form of the horizontal guide is changed to that of the horizontal guide 20a during shooting standby. By changing from the display form, it is possible to prevent the horizontal guide and the focusing mark 30 from becoming difficult to see.

On the other hand, in the processing step S11, when it is determined that the position where the horizontal guide 20a is displayed and the position where the focusing mark is displayed do not overlap (S11: NO), the horizontal guide is displayed in the display form from the time of standby for shooting. Is displayed unchanged. FIG. 6 is a display example of the LCD 124 when the image pickup device 1 is in the recording ready state and the display form of the horizontal guide is displayed without being changed. As shown in FIG. 6, when the position where the focusing mark 30 is displayed does not overlap with the position where the horizontal guide 20a is displayed, the horizontal guide and the alignment can be performed without changing the display form of the horizontal guide. The focus mark 30 is not difficult to see.

When the process of changing the display form of the tilt guide is completed, the process proceeds to the process step S7, and the CPU 100 determines whether or not the half-pressed state of the shutter button is released and the photographing device 1 is in the photographing standby state. When the recording preparation state of the photographing apparatus 1 continues (S7: NO), the tilt guide repeats the processing step S7 while maintaining the display form determined in the processing step S6. When it is determined that the photographing device 1 is in the photographing standby state (S7: YES), the display form of the tilt guide is returned to the display form shown in FIG. 3 (S8), and the process returns to the processing step S1.

In the flowchart shown in FIG. 2, each time the photographing apparatus 1 is in the recording ready state (S5), the position where the horizontal guide 20a is displayed and the position where the focusing mark is displayed are superimposed in the processing step S11. Whether or not to do so is determined once, but the present embodiment is not limited to this. For example, if the photographing device 1 or the subject moves while the photographing device 1 is in the recording ready state, the position of the subject in the focused state on the LCD 124 also changes. In this case, the focusing mark 30 may move following the subject in the focusing state. When the position of the focusing mark 30 moves, it may occur that the focusing mark 30 moves from a position where it does not overlap with the horizontal guide to a position where it overlaps. Alternatively, even if the horizontal guide is returned from the display form (horizontal guide 20b) shown in FIG. 5 to the display form (horizontal guide 20a) shown in FIG. 3 with the movement of the focusing mark 30, the focusing mark 30 is displayed. It is possible that the horizontal guides will not overlap. Therefore, the position of the focusing mark 30 is continuously monitored while the shutter button is pressed halfway, and a horizontal guide is provided according to the position of the monitoring focusing mark 30 so as not to overlap with the focusing mark 30. The display form of may be changed.

Further, when it is determined in the processing step S11 of FIG. 4 that the position where the horizontal guide 20a is displayed and the position where the focus mark is displayed do not overlap (S11: NO), the display form of the horizontal guide 20a is changed. It is not changed, but the present embodiment is not limited to this. For example, regardless of whether or not the position where the horizontal guide 20a is displayed and the position where the focus mark is displayed overlap, the horizontal guide is displayed as shown in FIG. 5 when the photographing device 1 is in the recording ready state. It may be changed to the form (horizontal guide 20b). While the photographing device 1 is in the recording ready state, the information (main information) that the user wants to confirm most on the LCD 124 is considered to be the through image 10 of the subject. Therefore, when the photographing device 1 is in the recording ready state, displaying the horizontal guide 20b below the inside of the LCD 124 makes it easier for the user to confirm the through image 10 of the subject.

(Second Embodiment)
Next, the photographing apparatus 1 of the second embodiment of the present invention will be described. The second embodiment of the present invention is the same as the photographing apparatus 1 of the first embodiment except that the process of changing the display form of the tilt guide (processing step S6 in FIG. 2) is different. Therefore, the process of changing the display form of the tilt guide according to the second embodiment will be described below.

FIG. 7 is a flowchart showing a process of changing the display form of the tilt guide according to the second embodiment of the present invention. In the second embodiment, the horizontal guide is photographed as shown in FIG. 3 without performing the determination process of whether or not the position where the horizontal guide 20a is displayed and the position where the focus mark is displayed overlap. The display form is changed from the horizontal guide 20a during standby and displayed (S21). The position where the focusing mark 30 is displayed changes according to the position of the subject in the focused state on the LCD 124. However, according to the specifications of the photographing device 1, the position where the focusing mark 30 is displayed is limited to a specific area of the LCD 124. Therefore, when the photographing device 1 is in the recording ready state, the horizontal guide and the focusing mark 30 are superposed and difficult to see by moving the horizontal guide to a position where the focusing mark 30 is not displayed. It can be prevented from becoming.

FIG. 8 is a display example of the LCD 124 when the photographing device 1 is in the recording ready state in the second embodiment. Of the display areas of the LCD 124, the area 124A surrounded by the dotted line is the area where the focusing mark 30 can be displayed. The dotted line indicating this area 124A is described for convenience of explanation and is not actually displayed on the LCD 124. Since the focusing mark 30 is displayed only in the area 124A, the horizontal guide 20b and the focusing mark 30 are overlapped by displaying the horizontal guide 20b on the outside of the area 124A (lower side in FIG. 8). Can be prevented. Further, in the second embodiment, since the determination process of whether or not the position where the horizontal guide 20a is displayed and the position where the focusing mark is displayed overlap is not performed, the load on the CPU 100 can be reduced. it can.

(Third Embodiment)
Next, the photographing apparatus 1 according to the third embodiment of the present invention will be described. The third embodiment of the present invention is the same as the photographing apparatus 1 of the first embodiment except that the process of changing the display form of the tilt guide (processing step S6 in FIG. 2) is different. Therefore, the process of changing the display form of the tilt guide according to the third embodiment will be described below. In the third embodiment of the present invention, when the photographing device 1 is in the photographing standby state, a horizontal guide corresponding to the levelness of the photographing device 1 is displayed on the LCD 124, and when the photographing device 1 is in the recording ready state. , The horizontal guide corresponding to the levelness including the correction value by the horizontal correction function of the photographing device 1 is displayed on the LCD 124.

FIG. 9 is a flowchart showing a process of changing the display form of the tilt guide in the third embodiment. In the process step S31, before the focusing mark is displayed on the LCD 124, the CPU 100 determines whether or not the position where the horizontal guide 20a is displayed and the position where the focusing mark is displayed overlap. If it is determined in the process step S31 that the position where the horizontal guide 20a is displayed and the position where the focus mark is displayed do not overlap (S31: NO), the process proceeds to the process step S32.

In the process step S32, the CPU 100 determines whether or not the horizontal correction function of the photographing device 1 is enabled. When it is determined in the processing step S32 that the horizontal correction function of the photographing device 1 is disabled (S32: NO), the LCD 124 displays the horizontal guide 20a together with the focusing mark 30 from the time of standby for photographing. Displayed unchanged. On the other hand, when it is determined in the processing step S32 that the horizontal correction function of the photographing device 1 is enabled (S32: YES), the correction amount by the horizontal correction function is added to the LCD 124 together with the focusing mark 30. A horizontal guide is displayed according to the levelness.

The horizontal correction function of the photographing device 1 corrects the horizontality of the photographing device 1 by rotating the solid-state image sensor 112 around the optical axis. For example, when the solid-state image sensor 112 can rotate around the optical axis within a range of ± 2 degrees, if the tilt (roll) of the photographing device 1 is within 2 degrees, the direction in which the photographing device 1 is tilted By rotating the solid-state image sensor 112 in the opposite direction, it is possible to capture a subject image without tilt. Therefore, when the horizontal correction function is effective, if the tilt of the photographing device 1 is within ± 2 degrees, the horizontal guide displays that the tilt of the photographing device 1 is zero. If the tilt of the photographing device 1 is larger than ± 2 degrees, a horizontal guide based on the tilt beyond the range of ± 2 degrees is displayed.

10 (a) and 10 (b) show the case where it is determined in the processing step S31 that the position where the horizontal guide 20a is displayed and the position where the focus mark is displayed do not overlap (S31: NO). The display example of the LCD 124 is shown. FIG. 10A is a display example of the LCD 124 when the horizontal correction function of the photographing device 1 is disabled (S32: NO), and FIG. 10B is a display example in which the horizontal correction function of the photographing device 1 is enabled. This is a display example of the LCD 124 in the case of (S32: YES). The display example of the LCD 124 shown in FIG. 10A is the same as the display example of the LCD 124 shown in FIG. 6, and the display form of the horizontal guide 20a is not changed from the display form in the shooting standby. In the display example of the LCD 124 shown in FIG. 10B, the size and display position of the horizontal guide 20a1 have not been changed since the shooting standby. However, the inclination line La1 is displayed with an inclination in which the correction amount by the horizontal correction function of the photographing device 1 is added.

If it is determined in the processing step S31 that the position where the horizontal guide 20a is displayed and the position where the focusing mark is displayed overlap (S31: YES), the process proceeds to the processing step S34. In the process step S34, the CPU 100 determines whether or not the horizontal correction function of the photographing device 1 is enabled. When it is determined in the processing step S34 that the horizontal correction function of the photographing device 1 is disabled (S34: NO), the horizontal guide 20b (see FIG. 11A) is prevented from overlapping with the focusing mark 30. The display form is changed to and displayed (S35). On the other hand, when it is determined in the processing step S34 that the horizontal correction function of the photographing device 1 is enabled (S34: YES), the horizontality to which the correction amount by the horizontal correction function is added is the horizontal guide 20b1 (FIG. 11). (See (b))) (S36). Further, the display form of the horizontal guides 20b and 20b1 displayed at this time is changed so as not to overlap with the focusing mark 30.

11 (a) and 11 (b) show the case where it is determined in the process step S31 that the position where the horizontal guide 20a is displayed and the position where the focus mark is displayed overlap each other (S31: YES). , Display example of LCD124 is shown. FIG. 11A is a display example of the LCD 124 when the horizontal correction function of the photographing device 1 is disabled (S32: NO), and FIG. 11B is a display example in which the horizontal correction function of the photographing device 1 is enabled. This is a display example of the LCD 124 in the case of (S32: YES). The display example of the LCD 124 shown in FIG. 11A is the same as the display example of the LCD 124 shown in FIG. 5, and the horizontal guide 20b is in the shooting standby shown in FIG. 3 so as not to overlap with the focusing mark 30. The display form has been changed from the horizontal guide 20a at the time. In the display example of the LCD 124 shown in FIG. 11B, the size and display position of the horizontal guide 20b1 are the same as when the horizontal correction function is disabled (FIG. 11A). However, the length of the bar Bb1 representing the horizontality is displayed as a length in which the correction amount by the horizontal correction function of the photographing device 1 is added.

When it is determined in the processing steps S32 and S34 of FIG. 9 that the horizontal correction function of the photographing device 1 is enabled (S32: YES, S34: YES), the correction amount by the horizontal correction function is added. The levelness is displayed on the horizontal guides (20a1, 20b1), but the present embodiment is not limited to this. Specifically, when it is determined that the horizontal correction function of the photographing device 1 is enabled, the horizontal guides (20a1, 20b1) display the horizontality of the photographing device 1 to which the correction amount is not added. You may. In this case, the range that can be corrected by the horizontal correction function is superimposed and displayed on the horizontal guide. As a result, when the photographing device 1 is tilted (rolled), the user can confirm whether or not the tilt can be corrected by looking at the horizontal guide. A display example of the horizontal guide in this case is shown in FIG. Specifically, FIG. 12A is a display example of the horizontal guide 20a2 in the processing step S33, and FIG. 12B is a display example of the horizontal guide 20b2 in the processing step S36. Both the auxiliary line S1 in FIG. 12A and the auxiliary line S2 in FIG. 12B represent a range that can be corrected by the horizontal correction function.

(Fourth Embodiment)
Next, the photographing apparatus 1 according to the fourth embodiment of the present invention will be described. The fourth embodiment of the present invention is the same as the photographing apparatus 1 of the first embodiment except that the process of changing the display form of the tilt guide (processing step S6 in FIG. 2) is different. Therefore, the process of changing the display form of the tilt guide according to the fourth embodiment will be described below. In the fourth embodiment of the present invention, when the photographing apparatus 1 is in the recording ready state, the horizontal guide, the focusing mark, and the exposure condition are displayed on the LCD 124. The exposure conditions displayed on the LCD 124 include an automatically or manually set shutter speed, aperture value, ISO sensitivity, exposure compensation value, and the like.

FIG. 13 is a flowchart showing a process of changing the display form of the tilt guide according to the fourth embodiment of the present invention. In the process step S41, before the focusing mark and the exposure condition are displayed on the LCD 124, the CPU 100 displays the position where the horizontal guide 20a is displayed and the focusing mark when the photographing device 1 is in the photographing standby state. It is determined whether or not the position to be displayed and the position where the exposure condition is displayed overlap.

If it is determined in the process step S41 that the position where the horizontal guide 20a is displayed, the position where the focus mark is displayed, or the position where the exposure condition is displayed overlaps (S41: YES), the process proceeds to the process step S42. In the process step S42, the focusing mark 30 and the exposure condition 40 are superimposed and displayed on the LCD 124, and the display form of the horizontal guide is changed so as not to be superimposed on the focusing mark 30 and the exposure condition 40. (See FIG. 14 (a)). On the other hand, in the processing step S41, when it is determined that the position where the horizontal guide 20a is displayed, the position where the focusing mark is displayed, or the position where the exposure condition is displayed does not overlap (S41: NO), the focusing mark 30 and the exposure condition 40 are superimposed on the through image 10 and displayed, and the horizontal guide is displayed without changing the display form from the time of standby for shooting.

FIG. 14 is a display example of the LCD 124 when the photographing device 1 is in the recording ready state in the fourth embodiment. Specifically, FIG. 14A shows a case where it is determined in the processing step S41 that the position where the horizontal guide 20a is displayed, the position where the focusing mark is displayed, or the position where the exposure condition is displayed overlap. (S41: YES) is a display example, and FIG. 14 (b) is a display example when it is determined in the processing step S14 that the layers are not superimposed (S41: NO). In the example shown in FIG. 14A, the focusing mark 30 is displayed at the position where the horizontal guide 20a was displayed during the shooting standby. Therefore, the display form of the horizontal guide is changed from the circular horizontal guide 20a in the standby state shown in FIG. 3 to a rectangular shape, and the display position is changed (horizontal guide 20b3). However, since the exposure condition 40 is displayed below the LCD 124, the horizontal guide 20b is displayed above the LCD 124 so as not to overlap with the exposure condition 40. On the other hand, in the display example shown in FIG. 14B, since the horizontal guide does not overlap with the focusing mark 30 and the exposure condition 40, the display form is displayed without being changed from the shooting standby state.

In the display example shown in FIG. 14A, the display form is changed so that the horizontal guide does not overlap with the focusing mark 30 and the exposure condition 40, but the present embodiment is not limited to this. When it is determined in the process step S41 that the position where the horizontal guide 20a is displayed, the position where the focusing mark is displayed, or the position where the exposure condition is displayed overlap, the display form of the horizontal guide is changed and the display form of the horizontal guide is changed. The display form of the exposure condition 40 may be changed from the display form shown in FIG. 14A.

In the present embodiment, the exposure condition 40 is displayed when the photographing device 1 is in the recording ready state, but the present embodiment is not limited to this. The exposure condition 40 may be displayed regardless of whether the photographing device 1 is in the photographing standby state or the recording ready state.

(Fifth Embodiment)
Next, the photographing apparatus 1 according to the fifth embodiment of the present invention will be described. A fifth embodiment of the present invention is the same as the photographing device 1 of the first embodiment except that both the horizontal guide and the elevation / depression guide are displayed on the LCD 124 as tilt guides.

FIG. 15 is a display example of the LCD 124 in the fifth embodiment of the present invention when the photographing device 1 is in the photographing standby state. As shown in FIG. 15, the horizontal guide 20a and the elevation / depression guide 50 are superimposed and displayed on the through image 10. The elevation / depression guide 50 has a rectangular shape, and a reference line Hv is displayed in the center thereof. Further, on the elevation / depression guide 50, a bar Bv is displayed so as to extend in the vertical direction from the central reference line Hv according to the elevation / depression angle calculated by the CPU 100. By visually recognizing the direction in which the bar Bv extends and the length of the bar Bv, the user can recognize how much the photographing device 1 is tilted in the vertical direction (how much it is tilted). Further, the elevation / depression guide 50 may be displayed even when the photographing device 1 is in the recording ready state. Further, the display form of the elevation / depression guide 50 is changed so that when the photographing device changes from the photographing standby state to the recording ready state, it does not overlap with the focusing mark 30 and other state information (horizontal guide, exposure condition). May be good.

(Sixth Embodiment)
Next, the photographing apparatus 1 of the sixth embodiment of the present invention will be described. The sixth embodiment of the present invention is the same as the photographing apparatus 1 of the first embodiment except that the focusing mark is not displayed on the LCD 124. Whether or not to display the focusing mark when the photographing device 1 is in the recording ready state may be changed according to the user operation to the operation unit 102.

16 (a) and 16 (b) are display examples when the horizontal guide is displayed on the LCD 124 in the sixth embodiment. 16 (a) and 16 (b) show display examples of the LCD 124 when the photographing device 1 is in the photographing standby state and the recording ready state, respectively. In the shooting standby state, the horizontal guide 20a is displayed large near the center of the LCD 124, as shown in FIG. 16A. When the photographing device 1 is in the recording ready state, as shown in FIG. 16B, the display form of the horizontal guide is changed from the photographing standby state, and the horizontal guide is displayed small below the LCD 124 (horizontal guide 20b).

In this way, when the photographing device 1 is in the photographing standby state, it is possible to easily confirm the state of the photographing device 1 by displaying the state information (tilt guide) of the photographing device 1 in a large size. When the photographing device 1 is in the recording ready state, the state information (tilt guide) of the photographing device 1 is displayed small or displayed at the end (for example, downward) in the LCD 124 to display a through image (that is, an image). The main subject placed in the center of the image) can be easily confirmed.

(7th Embodiment)
Next, the photographing apparatus 1 according to the seventh embodiment of the present invention will be described. In the seventh embodiment of the present invention, the focusing mark is not displayed on the LCD 124, and the display position and display mode of the exposure condition are controlled instead of the horizontal guide. Other than these points, it is the same as the photographing apparatus 1 of the first embodiment.

17 (a) and 17 (b) are display examples when the exposure condition is displayed on the LCD 124 in the seventh embodiment. 17 (a) and 17 (b) show display examples of the LCD 124 when the photographing device 1 is in the photographing standby state and the recording ready state, respectively. In the shooting standby state, as shown in FIG. 17A, the exposure condition 40a is largely displayed near the center of the LCD 124. When the photographing device 1 changes to the recording ready state, as shown in FIG. 17B, the display form of the exposure condition is changed from the shooting standby state, and the exposure condition is displayed small below the LCD 124 (exposure condition 40b). ..

In this way, when the photographing device 1 is in the photographing standby state, the state of the photographing device 1 can be easily confirmed by displaying the state information (exposure condition) of the photographing device 1 in a large size. When the photographing device 1 is in the recording ready state, the state information (tilt guide, exposure condition) of the photographing device 1 is displayed in a small size or displayed at the edge (for example, downward) in the LCD 124 to obtain a through image (for example, downward). That is, it is possible to easily confirm the main subject (the main subject arranged in the center of the image). In the seventh embodiment, the focusing mark may be displayed when the photographing apparatus 1 is in the recording ready state, and the position and form of the exposure condition may be controlled so as not to be superimposed on the focusing mark.

(Modification example)
In the first embodiment of the present invention, when the photographing device 1 is in the photographing standby state, a circular horizontal guide is displayed near the center of the LCD 124, but the present embodiment is not limited to this. 18 (a) to 18 (d) show other display examples of the horizontal guide when the photographing device 1 is in the photographing standby state, respectively. It should be noted that which display form of the horizontal guide is to be displayed may be changed according to the operation of the operation unit 102 by the user.

In the display example shown in FIG. 18A, the horizontal guide 20c is a reference line Hc extending in the left-right direction of the LCD 124 near the center of the LCD 124 and a tilt line Lc representing the horizontal direction (direction orthogonal to the gravity direction). Is displayed. In the display example shown in FIG. 18B, the horizontal guide 20d has a rectangular shape, and the reference line Vd is displayed in the center. Further, on the horizontal guide 20d, a bar Bd is displayed so as to extend in the left-right direction from the central reference line Vd according to the horizontality calculated by the CPU 100. In the display example shown in FIG. 18C, the horizontal guide 20e has a rectangular shape, and the reference line Ve is displayed in the center. Further, the horizontal guide 20e displays a mark Me that moves in the left-right direction from the central reference line Ve according to the horizontality calculated by the CPU 100. In the display example shown in FIG. 18D, the horizontal guide 20f is represented by an icon If indicating whether the photographing device 1 is rolling in a clockwise direction or a counterclockwise direction and a numerical value Nf indicating the size of the roll. Is displayed.

Further, in the first embodiment of the present invention, in the processing step 12, the display mode is changed so that the horizontal guide is displayed below the LCD 124, but the present embodiment is not limited to this. 19 (a) to 19 (d) show other display examples of the horizontal guide whose display form is changed in the processing step 12, respectively. It should be noted that which display form of the horizontal guide is to be displayed may be changed according to the operation of the operation unit 102 by the user.

In the display example shown in FIG. 19A, the horizontal guide is displayed with the display position changed from the case where the photographing device 1 is in the photographing standby state so as not to overlap with the focusing mark 30 (horizontal guide 20a3). ). In the display example shown in FIG. 19B, the horizontal guide is displayed in a reduced size from the case where the photographing device 1 is in the photographing standby state so as not to overlap with the focusing mark 30 (horizontal guide 20a4). ). In the display example shown in FIG. 19C, the horizontal guide is displayed in a reduced size as the display position is changed from the case where the photographing device 1 is in the photographing standby state so as not to overlap with the focusing mark 30. (Horizontal guide 20a5). In the display example shown in FIG. 19D, the display position and size of the horizontal guide have not been changed since the photographing device 1 was in the photographing standby state. However, the horizontal guide 20a6 is set to have a lower priority than the focusing mark 30, and the focusing mark 30 and the through image 10 are displayed in the area where the horizontal guide 20a6 and the focusing mark 30 overlap, and the horizontal guide 20a6 is not displayed. ..

In the display example shown in FIG. 19D, it is possible to easily confirm the subject in the focused state without changing the display position and size of the horizontal guide. Further, in this case, in the process of changing the shooting device 1 from the state in which the shutter button is not operated (shooting standby state) to the state in which the shutter button is half-pressed (recording preparation state), the display position and size of the horizontal guide are changed. Since it does not change, it is possible to easily confirm the change in the horizontality of the photographing device 1 by operating the shutter button. In the display example shown in FIG. 19D, the through image 10 or the horizontal guide 20a6 may be difficult to see depending on the position where the focusing mark 30 is displayed. Therefore, as shown in FIG. 19 (d), it is horizontal only when it is determined that the area where the horizontal guide is displayed and the position where the focus mark is displayed overlap is equal to or less than a predetermined value. Guides 20a6 may be displayed. In this case, if the area where the horizontal guide is displayed and the position where the focus mark is displayed overlap is larger than a predetermined value, the horizontal guide is displayed so that it does not overlap with the focus mark 30. Be changed.
