The sub CPU 112 is a CPU having a ROM / RAM built into one chip, and outputs output signals of the above-mentioned operation key units (SW1 to SW15) to the above-mentioned CPU block 1043 as user operation information. The built-in memory 107 is a memory for storing captured image data.
The acceleration sensor 111 as the tilt detecting means is mounted on the printed circuit board (PCB) constituting each part described above, and detects the two-axis X, Y data (X, Y) and the temperature T data to be a processor. It is sent to the I2C block 10411 of 104. Processor 104 is I2
Based on the data given from the acceleration sensor 111 via the C block 10411, the tilt information such as the roll angle to be displayed is calculated by, for example, the CPU block 1043 (tilt calculation means), and the size of the display scale of this roll angle is large. The display image corresponding to the above is selected (display processing means), and the image obtained by synthesizing the image of the marker M as a mark at the position indicating the roll angle on the display image is displayed on the LCD monitor 5 or the like (image display). Display on the device).

When X0 and Y0 are the output data of the data (X, Y) of the two axes X and Y at zero gravity, the roll angle θ with respect to the horizontal of the acceleration sensor 111 is expressed by the following equation (1).
θ [deg] = 180 / π * arctan {(Y-Y0) / (X-X0)} ... (1)
Similarly, another accelerometer 111 installed so as to detect the inclination of the image pickup device in the pitching direction detects the pitch angle to be displayed and sends the data to the processor 104. Based on the data transmitted from the acceleration sensor 111, the processor 104 calculates the tilt (pitch angle) of the image pickup device to be displayed by, for example, the CPU block 1043 (tilt angle calculation means), and photographs the image on a part of the LCD monitor 5. It can be displayed superimposed on the image (however, this function is optional and can be omitted, but if this function is provided, only the roll angle or only the pitch angle, or both the roll angle and the pitch angle , It is preferable to provide a selection button for instructing the user to select the display.)
The processor 104 determines the calculated roll angle and / or pitch angle magnitude when displaying the roll angle and / or pitch angle on the LCD monitor 5, and displays this angle according to the magnitude of this angle. Change the range of the display scale. This display scale has
A display of a marker M, which is a pseudo bubble image like a bubble in a level using a liquid, a so-called level, is added, and the angle is recognized by looking at the scale of the scale on which the marker M is located. do. Therefore, the processor 104 synthesizes an image of the marker M indicating the angle on the display scale in which the range is selected and displays it on the LCD monitor 5. Further, the angle shall be recorded in the built-in memory 107 or the like.

In the processor 104, the roll angle (which does not directly indicate the inclination of the image pickup device) obtained by the equation (1) is in a state as shown in FIG. 3 (a) of the image pickup device, that is, the image pickup device is horizontal. On the other hand, when the range is 0 degrees ± 5 degrees to ± 60 degrees, the display scale B1 indicating the roll angle is displayed.
Sideways with respect to the display screen of the LCD monitor 5 (direction along the longitudinal direction of the display screen of the imaging device)
It can be configured to be displayed on the screen in the state. On the other hand, when the roll angle of the image pickup device in the left-right direction with respect to the horizontal is within a predetermined small range, for example, 0 degrees ± 5 degrees, which is close to the horizontal, the roll angle can be accurately measured in FIG. 3 (b). ), Display scale B2
Automatically expands the range of. Further, the roll angle is ± 6 as shown in FIG. 4 (b).
When it exceeds 0 degrees, the screen display can be configured to switch to the portrait orientation (vertical position).
Further, the image pickup apparatus enlarges the display scale B2 to improve the accuracy when the roll angle reaches the region of 90 degrees ± 5 degrees (near the vertical). In general, the user can recognize that the image pickup apparatus is tilted with little visual inspection when the image pickup apparatus is tilted significantly from the horizontal to the left and right. However, when the image pickup device is in a horizontal state considered to be a shooting posture, it is desired to strictly confirm whether or not the image pickup device is correctly horizontal. Therefore, the image pickup device according to this embodiment. Then, as described above, when the roll angle is near the horizontal (0 degree ± 5 degree), the range of the display scale B2 can be expanded, so that the position of the marker M can be read accurately. It is possible to accurately respond to such user requests.

The vertical neighborhood is not necessarily limited to 0 degrees ± 5 degrees, and is, for example, 0 degrees ±.
It may be 4 to 7 degrees.
Further, as shown in FIG. 6, the processor 104 is configured to always display only one display scale, and the scale intervals (scales) of the display scale B3 are displayed at equal intervals, that is, linearly. If the roll angle is close to horizontal (center when marker M is near the center), the part is displayed in a fine range, and if the roll angle is not close to horizontal, for example, 0 degrees ± 5
In the case of 60 degrees ± 5 degrees from the degree, the part where the marker M is located is displayed in a coarse range.
It can also be configured to provide a non-linear display.
As a result, the roll angle can be displayed with high accuracy at the timing when only one display scale is used and accuracy is required without switching the display scale B3 itself. For example, the scale interval of the display scale can be arbitrarily changed non-linearly by displaying a logarithmic display or a power display when the roll angle is ± 1 degree or later.

Further, the display processing means included in a part of the processor 104 is a state in which the roll angle is close to horizontal (0 degree ± 5 degrees) and a normal state in which the roll angle is not close to horizontal (0 degree ± 5 degrees) in the above-described roll angle display method. The number of samples and the number of average processes of the acceleration sensor 111 can be changed depending on the case (0 degree ± 5 degrees to 0 degree ± 60 degrees). That is, in the normal state where the image pickup device is not close to horizontal, the number of sampled roll angles and the number of average processes of the roll angle in the acceleration sensor 111 are controlled to be small so that the approximate inclination of the image pickup apparatus can be displayed instantly. It is possible to cope with a sudden change in the tilt of the image pickup device. On the other hand, when it is close to the horizontal state (0 degree ± 5 degrees), the display processing means controls so that the number of samples and the average number of processes of the roll angle acceleration sensor 111 in the acceleration sensor 111 are increased, so that the inclination is increased. The value can be configured to be displayed with high accuracy. Also, in the normal state and the horizontal state,
It can be configured to change the moving speed of the marker M that moves along the display scale. That is, in the normal state, it is possible to give priority to speeding up the response by increasing the response speed, and in the horizontal state, it is possible to give priority to slowing down the response speed to make it easier for the user to align the image pickup device horizontally.

Further, when the pitch angle (so-called tilt angle in the front-rear direction) falls within the range of 0 degree ± 5 degrees to 0 degree ± 60 degrees, the processor 104 has a pitch angle having a wide range as shown in FIG. The display scale B4 can be configured to be displayed on the screen in a portrait orientation with respect to the display screen of the LCD monitor 5.
Further, in the range of this display scale B4, when the pitch angle approaches 0 degrees (0 degrees ± 5 degrees) and the vertical vicinity (90 degrees ± 5 degrees), the inclination of the image pickup apparatus can be accurately measured. That is, as shown in the display scale B5 shown in FIG. 7, the range can be automatically expanded so that high-precision reading can be performed.
Further, in the above-described pitch angle display method, the processor 104 (display processing means) has a state in which the pitch angle is close to vertical (90 degrees ± 5 degrees) and a normal state in which the pitch angle is not close to vertical (0 degrees ± 5). The number of samples and the number of average processes of the acceleration sensor 111 can be changed depending on whether the degree is 0 degrees ± 30 degrees). That is, the normal state (0 degree ± 5) that is not close to vertical
In the case of 0 degree ± 30 degrees from degrees), the number of samplings and average processing of the pitch angle in the accelerometer 111 is controlled to be small so that the approximate inclination of the imaging device can be displayed instantly. It is possible to cope with a sudden change in the tilt of the image pickup device.

On the other hand, in the case of being close to vertical (near vertical) (90 degrees ± 5 degrees), the processor 104 controls so that the number of samples and the average number of processes of the acceleration sensor 111 of the pitch angle in the acceleration sensor 111 are increased. It can be configured to display the tilt value with high accuracy. Further, it can be configured to change the moving speed of the marker M that moves along the display scale between a normal state (a state deviating from the horizontal vicinity) and a state close to horizontal. That is, in the normal state, it is possible to give priority to speeding up the response by increasing the response speed, and in the horizontal state, it is possible to give priority to slowing down the response speed to make it easier for the user to align the image pickup device horizontally.
Hereinafter, the processing of the processor 104 that functions as the display processing means when displaying both the roll angle and the pitch angle in combination will be described.
When the roll angle is 0 degrees ± 60 degrees or less, the processor 104 sets the roll angle to LC.
The display scale B1 and the marker M in the landscape orientation are displayed on the display screen of the D monitor 5, and the pitch angle is displayed by the display scale B5 and the marker M in the portrait orientation as shown in FIG. Can be configured. Also, when the roll angle exceeds 0 degrees ± 60 degrees (not shown)
Can be configured to switch the roll angle display to the portrait display scale and the pitch angle display to the landscape display scale.

Further, the processor 104 can be configured so that the display scale for displaying the width of the display range is wide and the display scale for displaying the width of the display range is different in coloring. For example, from a state where the roll angle and / or pitch angle is 0 degrees ± 5 degrees to 0 degrees ± 6
When the inclination becomes large to the state of 0 degrees, the coloring of the display scale is changed. Further, the display scale is colored even when the inclination increases from the state where the roll angle and / or the pitch angle is 90 degrees ± 5 degrees to the state where the roll angle and / or the pitch angle is 90 degrees ± 30 degrees. As a change form of this coloring, for example, switching from a black display scale to a red display scale can be considered.
Further, a selection button (not shown) is provided on the operation surface of the image pickup apparatus to instruct the user to select and display only the roll angle, only the pitch angle, or both the roll angle and the pitch angle as a tilt guide display. It can be configured.
3 to 10 are explanatory views showing a display method for displaying an inclination in the image pickup apparatus according to the embodiment of the present invention.
Hereinafter, a specific display method for displaying the inclination of the image pickup apparatus according to the first to eighth embodiments will be described with reference to FIGS. 3 to 9.

As shown in FIG. 3A, the display scale B1 indicating the roll angle is displayed, and the display scale B1 indicating the roll angle is displayed. It is configured to be displayed near the bottom edge of the screen. The range of this display scale B1 is automatically expanded so that the roll angle can be accurately measured when the roll angle reaches a region approaching horizontal with 0 degrees ± 5 degrees, that is, a region near the horizontal. Let me. (The scale is enlarged and the accuracy is higher in the range of the display scale B2 shown in FIG. 3B than in the range of the display scale B1 shown in FIG. 3A). Further, as shown in FIG. 4 (b), when the roll angle exceeds ± 60 degrees (
The vertical direction of the screen is generally considered to be a vertical position in the vertical direction), and the display is automatically switched to the vertical position as in the display scale B1. Further, as shown in FIG. 5A,
When the roll angle falls within the range of 90 degrees ± 5 degrees to 90 degrees ± 30 degrees, the display scale B1 in the reduced range is displayed, and as shown in FIG. 5 (b), the roll angle is vertical. In the case of close 90 degrees ± 5 degrees, the range is expanded and the angle can be calculated with high accuracy. Display scale B2

In addition, the scale of the area where the roll angle is close to horizontal is displayed in a fine range, and the scale scale of the area where the roll angle is not close to horizontal (roll angle is 0 degrees ± 30 degrees) is displayed in a coarse range. It is configured. With this configuration, the roll angle can be reasonably displayed without switching the display scale itself. As a display method, for example
The scale interval of the display scale B3 can be arbitrarily changed by displaying a logarithmic display or a power display when the roll angle is ± 1 degree or later.

[Third Embodiment]
In the third embodiment, the display method of the roll angle or the pitch angle is the same as the display method shown in the first and second embodiments, but the processor 104 has a horizontal roll angle or pitch angle. The number of samples and the average number of processes of the accelerometer 111 are changed depending on whether the state is close to (0 degrees ± 5 degrees) or not horizontal (0 degrees ± 5 degrees to 0 degrees ± 60 degrees). It is configured as follows. That is, in the case of a non-horizontal normal state, the number of samples and the number of average processes of the roll angle or pitch angle in the acceleration sensor 111 are reduced so that the approximate inclination of the image pickup apparatus can be displayed instantly. On the other hand, when the roll angle or the pitch angle is close to the horizontal state, the processor 104 is configured to increase the number of samples and the average number of processes of the roll angle acceleration sensor 111 in the acceleration sensor 111 to increase the inclination value.

Further, the range of the display scale B4 is the display scale shown in FIGS. 7 and 8 so that the inclination of the image pickup apparatus can be accurately measured as the pitch angle approaches horizontal with 0 degrees ± 5 degrees. Like B5, the range is automatically enlarged and displayed.

[Fifth Embodiment]
In the fifth embodiment, the pitch angle display method is the same as the display method shown in the fourth embodiment, but the processor 104 is in a state where the pitch angle is close to a right angle (90 degrees ± 5 degrees). ) And the non-vertical state (90 degrees ± 5 degrees to 90 degrees ± 60 degrees), the difference is that the number of samples and the average number of processes of the acceleration sensor 111 are changed. That is, in the normal state, the number of samples and the number of average processes of the pitch angle in the acceleration sensor 111 are reduced so that the approximate inclination of the image pickup apparatus can be displayed instantly, while the pitch angle is horizontal. When close to the state, the processor 104 is the accelerometer 11.
It is configured so that the number of samplings and the average number of processes of 1 are increased so that the inclination value can be displayed with high accuracy. Further, in this embodiment, the moving speed of the marker M for moving the display scales (B1, B2) is changed between the normal state and the horizontal state. With this configuration, the response speed is increased in the normal state to enable quick response, and the response speed is slower in the horizontal state, making it easier for the user to align the image pickup device horizontally.

[Sixth Embodiment]
Hereinafter, a sixth embodiment in which the roll angle and the pitch angle are combined will be described with reference to FIG.
In the sixth embodiment, as shown in FIG. 10, when the roll angle is 0 degrees ± 5 degrees or less, the roll angle is displayed on the display scale B2 in a horizontal state with respect to the display screen of the LCD monitor 5. However, the pitch angle is displayed on the display scale B5 in the vertical orientation state. Also, the roll angle is 0.
When the degree exceeds ± 60 degrees, the roll angle display is switched to the vertical display scale and the pitch angle display is switched to the horizontal display scale, although not shown.

[7th Embodiment]
In the seventh embodiment, the coloring is different between the display scale that displays the width of the display range wide and the display scale that displays the width of the display range narrowly. For example, when the roll angle and / or pitch angle is 0 degrees ± 5 degrees, what was displayed in black is changed to 0.
When the inclination becomes large to the state of degrees ± 60 degrees, the color of the display scale is changed to red. Also, from the state where the roll angle and / or pitch angle is 90 degrees ± 5 degrees, 90 degrees ± 30

A combination such as yellow may be used.

[Eighth Embodiment]

For the user, it is possible to perform accurate shooting by appropriately operating the selection button according to the shooting target, which improves convenience.

[9th Embodiment]
Next, in the above-mentioned imaging device, a ninth embodiment of the present invention is based on the premise that both the roll angle and the pitch angle of the imaging device are displayed by using an orthogonal three-axis acceleration sensor as the acceleration sensor 111. Will be described.
If an acceleration sensor 111 having outputs of three axes orthogonal to each other is used and the direction in which the acceleration sensor 111 is incorporated in the imaging device is known, the magnitude of the acceleration applied to each axis is the gravitational acceleration in the axial direction. Since it is disassembled into two parts, it is possible to accurately know the tilt of the image pickup device in all directions.
In this case, as shown in FIG. 10, when the image pickup device is held in the horizontal position, the rotation around the Z axis is in the roll direction, the rotation around the X axis is in the pitch direction, and the rotation around the Y axis is in the yaw direction. It becomes. When the image pickup device is held horizontally, the acceleration detected by the Y-axis is substantially equal to the gravitational acceleration, and the values detected by the X-axis and the Z-axis are almost zero. In this way, the approximate orientation of the image pickup apparatus can be known by detecting which axis mainly detects the gravitational acceleration.
The tilt data detected by the acceleration sensor 111 is CP via the I2C block 10411.
Received by the U block 1043, the main detection axis of the gravitational acceleration and the magnitude of the inclination are calculated by software or hardware, and the result is displayed on the display device.

At this time, as shown in FIG. 11, the roll angle and the pitch angle, which are inclinations in the roll direction and the pitch direction, are displayed on the LCD monitor 5 of the image pickup apparatus.
In the case of FIG. 11, the display modes of the tilt guide display G1 indicating the roll angle and the tilt guide display G2 indicating the pitch angle are almost the same, but the gauge of the tilt guide display G1 along the longitudinal direction of the display screen is tilted in the roll direction. , And the gauge of the tilt guide display G2 along the lateral direction of the display screen indicates the tilt in the pitch direction. In each gauge, it means that when the position of the square mark is in the center as shown, the tilt angle, that is, the roll angle and pitch angle is zero, and the tilt angle, that is, the roll angle and pitch angle, increases as the distance from the center increases. ..
FIG. 12 shows a display example when the image pickup apparatus is held in the vertical position. In this case, the display form of the tilt guide display in the roll direction and the pitch direction is apparently almost the same as that in FIG. 11, but the difference from FIG. 11 is that the display device has a gauge in the lateral direction. The tilt guide display G3 shows the roll angle which is the tilt in the roll direction, and the tilt guide display G4 having a gauge in the longitudinal direction shows the pitch angle which is the tilt in the pitch direction.

However, when the tilt guide display in the roll direction and the pitch direction is switched when the holding direction is changed in this way, it becomes difficult to distinguish between the two. In order to deal with this, in this embodiment, as shown in FIG. 13, the display colors of the tilt guide display in the roll direction and the pitch direction are different, and the display color of the marker of the tilt guide display Gr1 in the roll direction is changed. For example, red is used, and the display color of the marker of the tilt guide display Gp1 in the pitch direction is, for example, blue. In this case, for example, even when the orientation of the image pickup apparatus is changed from the horizontal position to the vertical position in FIG. 13, the red color is the tilt guide display Gr1 in the roll direction, and the blue color is the tilt guide display Gp1 in the pitch direction. By making the display colors different in this way, the relationship between the gauge of each tilt guide display and the roll angle and pitch angle can be intuitively understood even when the vertical and horizontal directions are switched.

[10th Embodiment]
In the tenth embodiment, for the same purpose, as shown in FIG. 14, the display form of the tilt guide display in the roll direction and the pitch direction is different, for example, the tilt guide display G in the roll direction.
The gauge of r2 has the lowest height in the center and is narrow, and the height gradually increases and becomes wider toward both ends, and the gauge of the tilt guide display Gp2 in the pitch direction has a rectangular shape with a normal width. And. In this case as well, for example, even when the orientation of the image pickup apparatus is changed from the horizontal position to the vertical position in FIG. 14, the wider both ends are the tilt guide display Gr2 in the roll direction, and the uniform width is the tilt in the pitch direction. The guide display is Gp2. By changing the display form in this way, the relationship between the gauge of each tilt guide display and the roll angle and pitch angle can be intuitively understood even when the vertical and horizontal directions are switched.
In the ninth and tenth embodiments, when the display of the tilt guide display in the pitch direction is not always required, a means for hiding the tilt guide display in the pitch direction is provided by setting the program. Is also feasible in the configurations shown in FIGS. 1 and 2. That is, the screen for setting the display presence / absence of each gauge is displayed on the display means such as the LCD monitor 5, and the result of the setting using the operation buttons (not shown) is stored in the EEPROM or the main memory and displayed. It may be displayed according to the setting contents called at times.

[11th Embodiment]
Next, in the above-mentioned imaging device, it is premised that an orthogonal two-axis acceleration sensor is used as the acceleration sensor 111, and the tilt guide display of the roll angle is displayed only when the pitch angle of the imaging device is within a predetermined range. The eleventh embodiment of the present invention will be described.
The acceleration sensor 111 is mounted perpendicularly to the imaging device on the main PCB (printed circuit board) on which the processor 104 or the like is mounted, that is, on the main board, and outputs data on two orthogonal axes X and Y and temperature T. do. The tilt of the imaging device is calculated from the data, and the corresponding tilt guide display is displayed on the LCD monitor 5 or the like.
The roll angle θ of the acceleration sensor 111 with respect to the horizontal is expressed by the above-mentioned equation (1).
The pitch angle φ is expressed by the following equation (2).
φ [deg] = 180 / π * arctan (Gz / Gxy)
Gz = sqrt (Gxyz ^2- Gxy ² )
Gxy = sqrt {(X-X0) ² + (Y-Y0) ² } ... (2)
Here, Gxyz is an output value at 1 G, and X0 and Y0 are outputs at zero gravity, respectively.

Then, the acceleration sensor 111 is mounted perpendicularly to the image pickup apparatus. More specifically, for example, the acceleration sensor 111 is mounted vertically on the main board in a portion closer to the right end and closer to the lower end when viewed from the back side of the image pickup apparatus, but is not necessarily limited to this position. is not it. If the pitch angle is increased in this state, the output values of the X-axis and the Y-axis output from the acceleration sensor 111 gradually become smaller, and are easily affected by noise and offset deviation. That is, the more the pitch angle is added, the lower the display accuracy of the roll angle is. Therefore, when the pitch angle becomes a certain angle as shown in FIGS. 15 to 17 and 18 to 20, for example, the display is blinked, the marker indicating the angle displayed on the bar is turned off, and a warning sound is emitted. Warn by ringing. 15 to 17 show a case of a horizontal position, where (a) is a perspective view and (b) is a side view. FIG. 15 shows a state in which the image pickup apparatus is almost vertical, FIG. 16 shows a state in which a pitch angle is slightly added, and FIG. 17 shows a state in which a large pitch angle is added, and the roll is used for warning. The tilt guide display G of the corner is blinking. 18 to 20 show the case of the vertical position, where (a) is a perspective view and (b) is a side view. FIG. 18 shows a state in which the image pickup apparatus is substantially vertical in the vertical position, FIG. 19 shows a state in which a pitch angle is slightly added, and FIG. 20 shows a warning when a large pitch angle is added. Therefore, the tilt guide display G of the roll angle is blinking.

[Twelfth Embodiment]
Next, a twelfth embodiment of the present invention will be described on the premise that the tilt guide display of the roll angle is displayed only when the temperature of the image pickup device is within a predetermined range in the above-mentioned image pickup device.
When the temperature is changed, the output values of the X-axis and the Y-axis of the acceleration sensor 111 change accordingly. For example, if the output values of the X-axis and the Y-axis are reduced by raising the temperature, in such a case, it is easily affected by noise and offset deviation. Therefore, when the output T of the acceleration sensor 111 reaches an output value that is outside the standard range, the pitch angle or roll angle display that has been displayed up to that point is blinked, and the angle displayed on the bar. A warning is given by turning off the marker M indicating the above, sounding a warning sound, or the like.
Also in this case, the display form is substantially the same as in the cases of, for example, FIGS. 17 and 20.

[13th Embodiment]
Next, a thirteenth embodiment according to the image pickup apparatus of the present invention will be described.
In the above-mentioned imaging device, when the pitch angle is increased and the imaging device is placed in a flat state, both X and Y become 0G, and the roll angle cannot be calculated. Since the output values of X and Y decrease even in the vicinity of 0G, the accuracy deteriorates. Therefore, assuming that the position of the display bar of the tilt guide display G is changed depending on the angle of the imaging device as shown in FIG. 21, the display bar of the tilt guide display G is displayed when X and Y are near 0 G (for example, the threshold value is 0.1 G or less). It is possible to determine whether the position of is to be arranged along the longitudinal direction as shown in FIG. 21 (a) or along the lateral direction as shown in FIG. 21 (b). Can not. The display method in such a case is shown in the flowchart of FIG.
It is determined whether or not the output values Xt = n and Yt = n when t = n are 0.1 G or less (step S11), and when both are not 0.1 G or less, the output value Xt = as it is. Calculate θ using n and Yt = n (step S12) and display it on the monitor (step S1).
3).

However, when the output values of Xt = n and Yt = n are both 0.1 G or less, X and Y
It is determined whether or not the output values of both are 0.1 G or less before m seconds (step S14).
), The angle θ is determined from the output values Xt = n−m and Yt = n−m m seconds before both are not 0.1 G or less, the position of the display bar is determined (step S15), and the process proceeds to step S13. And display it on the monitor. At that time, the position of the bar of the tilt guide display is fixed until either output value becomes 0.1 G or more to prevent the bar position from being unnecessarily changed and becoming difficult to see. This is the same during playback, and when the display orientation is rotated depending on the angle of the image pickup device, it is not possible to determine in which direction the image should be rotated if the image pickup device is placed flat, but this is also the monitoring display bar. Change the display orientation by the same process as. In addition, no matter how many values of m are, m
When both Xt = n−m and Yt = n−m in the state before seconds are 0.1 G or less, a warning is displayed in substantially the same manner as in the eleventh embodiment (step S16).

[14th Embodiment]
Next, a fourteenth embodiment according to the image pickup apparatus of the present invention will be described.
If the pitch angle is set and both X and Y are output values below the threshold value and the warning display is displayed as described above, it is not necessary to obtain high accuracy, so the number of samplings is reduced. Therefore, it is possible to prevent the processing system such as the processor 104 from being overloaded and reduce the power consumption.
