  Since the function and operation of each member of the camera 10 are known, the description thereof will be omitted, and the system configuration inside the camera will be described with reference to FIG.

  The lens barrel unit 14 includes an objective lens 141, a zoom lens 142, a shutter combined diaphragm 143, a focus lens 144, a low-pass filter (LPF) 145, an image sensor 146, and the like.

The formed light beam is received and converted into an analog image signal, and the analog image signal is output toward the A / D converter 21 at the subsequent stage.

  The A / D converter 21 converts the analog image signal input from the image sensor 146 into a digital image signal, and the digital image signal forms part of a processing circuit that performs image processing on the image signal from the imaging optical unit. Input to the image processing unit 22.

  The image processing unit 22 performs image compression and other processes to generate image data, and the image data processed by the image processing unit 22 based on the overall control of the system controller 20 includes a memory card, a flash memory, a RAM, and the like. Stored in the memory group 23.

  In addition to these controls, the system controller 20 drives and controls the monitor unit 17, the strobe light emitting unit 12, and the strobe control unit 12a. Various commands are input to the system controller 20 by operation keys 19.

  The camera 10 includes an inclination sensor 25 that is used as a level for detecting the inclination angle of the imaging apparatus main body. Here, an acceleration sensor that measures acceleration is used as the tilt sensor 25. By using this acceleration sensor, the inclination of the main body case 11 with respect to the direction of gravity can be measured.

  The system controller 20 determines the tilt angle of the main body case 11 based on the output signal from the tilt sensor 25. That is, the system controller 20 detects the inclination angle of the main body case 11 with respect to the gravity direction around the optical axis direction (Z direction) of the lens barrel unit 14 (hereinafter also referred to as the roll direction).

  The subject image P is displayed while being tilted with respect to the monitor screen 17a of the monitor unit 17 in accordance with the tilt angle of the main body case 11 under the control of the system controller 20, as shown in FIG.

  In this embodiment, the tilt control of the camera body of the system controller 20 is performed by checking the display items displayed on the monitor screen 17a based on the command of the operation key 19 or by inputting numerical values into the display items. Is called.

  When the camera 10 is turned on, an initial screen FG is displayed on the monitor screen 17a as shown in FIG. On this initial screen FG, menu screen settings and other various items are displayed. When the menu screen setting item is selected with the operation key 19 on the initial screen FG, the monitor screen 17a shifts to the menu screen MEG shown in FIG.

  In this menu screen MEG, it is assumed that an item for setting whether to turn on or off the tilt sensor 25 and a shooting mode are set. An item for setting whether to perform shooting (monochrome shooting or sepia shooting), whether horizontal shooting with the bottom surface 11d parallel to the horizontal line is set as an initial reference angle, or vertical shooting with the bottom surface 11d perpendicular to the horizontal. An initial setting reference angle item for setting whether to set an initial setting reference angle, an inclination angle setting item for setting an inclination angle of the main body case 11 with respect to the initial setting reference angle as a setting reference angle, and a main body case 11 set by the inclination angle setting item An allowable angle range setting item for setting an allowable angle range of the inclination of the main body case 11 with respect to the set reference angle is displayed.

  In this camera 10, when the power is turned on, an initial value is determined so that color shooting can be performed in the color shooting mode. In the camera 10, when the power is turned on, the initial value is determined so that the horizontal shooting is set as the initial reference angle. In the camera 10, the initial value is determined so that the allowable angle range of the inclination of the main body case 11 with respect to the initial set reference angle is a range of plus or minus 5 degrees with the set reference angle as the center.

  In this embodiment, the system controller 20 determines, based on the detection output of the tilt sensor 25, when the tilt angle of the main body case 11 is within the allowable angle range with respect to the set reference angle and when the tilt angle of the main body case 11 is outside the allowable angle range. There is a function of executing processing for changing the color of the subject image P displayed on the monitor screen 17a depending on when there is.

  That is, in principle, the system controller 20 displays the subject image P in color on the monitor screen 17a based on the detection output of the tilt sensor 25 when the tilt angle of the main body case 11 is within the allowable angle range with respect to the set reference angle. In addition, when the tilt angle of the main body case 11 is outside the allowable angle range with respect to the set reference angle, there is a function of executing processing for displaying the subject image P on the monitor screen 17a in a single color.

  In addition, the system controller 20 displays the subject on the monitor screen 17a when the tilt angle of the main body case 11 is within the allowable angle range with respect to the set reference angle based on the detection output of the tilt sensor 25 under predetermined conditions. When the image P is displayed in a single color and the tilt angle of the main body case 11 is out of the allowable angle range with respect to the set reference angle, there is also a function of executing processing for displaying the subject image P in color on the monitor screen 17a.

  Here, monochrome or sepia is used for single color display. The following arithmetic processing is used for the color display processing.

  For example, the system controller 20 executes the following calculation when converting each image data (R, G, B) stored in the memory group 23 into YUV data.

The system controller 20 uses color calculation processing to
“Y (U, V) = aR + bG + cB + d
However, a, b, and c are coefficients to be applied to each data, and d is a constant. ”Is executed.

The system controller 20 uses black and white arithmetic processing.
“Y = aR + bG + cB + d
U (or V) = xR + yG + zB + t
However, x, y, z are coefficients to be applied to each data, t is a constant, and each coefficient x, y, z, constant t is “0”. Here, setting each coefficient x, y, z, and constant t to “0” means removing a component related to the color. ”Is executed.

The system controller 20 uses
“Y = aR + bG + cB + d
U (or V) = xR + yG + zB + t
However, each coefficient x, y, z is “0”, and the constant t is a characteristic value (offset value) other than “0”. Sepia is expressed by setting the constant t to a predetermined value. ”Is executed.

  The system controller 20 also has a function as a brightness detection unit that detects the brightness of the subject image P based on the brightness data obtained in the color calculation.

  When the brightness of the subject image P is greater than or equal to the first threshold, the system controller 20 reduces the display brightness of the monitor screen 17a when the tilt angle of the main body case 11 is outside the allowable angle range with respect to the set reference angle. When the tilt angle of the main body case 11 is within the allowable angle range with respect to the set reference angle, the display brightness of the monitor screen 17a is set to be high.

  Further, when the brightness of the subject image P is less than the second threshold, the system controller 20 displays an indicator described later on the monitor screen 17a when the tilt angle of the main body case 11 is outside the allowable angle range with respect to the set reference angle. I (refer to FIG. 10) or a function of displaying a sign representing an angle. Note that the first threshold value is larger than the second threshold value.

  Details of the processing of the system controller 20 will be described below with reference to the flowchart shown in FIG.

  When the photographing mode is set, the system controller 20 determines whether the tilt sensor 25 is turned on or off (S.1). When the tilt sensor 25 is off, the system controller 20 performs S.P. Move to 2. The system controller 20 is S.I. In No. 2, processing related to inclination detection described later is not performed. Accordingly, only the subject image P is displayed on the monitor screen 17a, and no information regarding the tilt of the main body case 11 is presented.

  Here, description will be made assuming that the inclination sensor 25 is on. When the tilt sensor 25 is on, the system controller 20 performs S.P. Then, the process proceeds to step 3, and it is determined whether or not the horizontal shooting is set to the initial reference angle.

  When the system controller 20 determines that the horizontal shooting is the initial setting reference angle, the index bar constituting the indicator I described later when the tilt sensor 25 outputs a signal corresponding to the angle “0 degrees” with respect to the horizontal. Can be executed so as to be arranged in a straight line with an interval in the extending direction of the bottom surface 11d (S.4).

  Next, when the system controller 20 determines that the vertical shooting is the initial reference angle, the system controller 20 configures an indicator I described later when the tilt sensor 25 outputs a signal corresponding to the angle “90 degrees” with respect to the horizontal. It is possible to execute a process of arranging the index bars so as to form a straight line with an interval in the extending direction of the side surface 11e (S.5). In either case, an indicator I, which will be described later, is displayed on the lower part of the monitor screen 17a.

  Next, the system controller 20 performs S.I. 6 to determine whether the tilt angle of the main body case 11 with respect to the set reference angle is within the allowable angle range. The setting reference angle here refers to the inclination angle of the main body case 11 set by the user when the inclination angle of the main body case 11 with respect to the initial setting reference angle is set as the setting reference angle by the user. Including.

  When the tilt angle of the main body case 11 is outside the allowable angle range, the system controller 20 determines whether the brightness of the subject image P is equal to or greater than the first threshold (S.7). If the brightness of the subject image P is greater than or equal to the first threshold value, after the process of setting the display brightness of the monitor screen 17a to be low (S.8), the S.P. 11

  The system controller 20 is S.I. 7, when the brightness of the subject image P is less than the first threshold, S.I. Move to 9. The system controller 20 is S.I. 9, it is determined whether or not the brightness of the subject image P is equal to or less than the second threshold value. When the brightness of the subject image P is less than or equal to the second threshold, the system controller 20 executes an indicator I display process (S.10) described later, 11 The system controller 20 is S.I. 9, when the brightness of the subject image P exceeds the second threshold, S.I. 11

  The system controller 20 is S.I. 11, it is determined whether a mode for photographing with 16 or more colors is selected or a single color photographing mode for photographing with a single color is selected. When the color shooting mode is selected, the system controller 20 executes a calculation for displaying the subject image P in a single color on the monitor screen 17a (S.12). By this processing, the subject image P is displayed on the monitor screen 17a as a monochrome image or a sepia image (S.13). Whether the subject image P is displayed as a monochrome image or a sepia image depends on the user's setting.

  When the single color shooting mode is selected, the system controller 20 executes a calculation for displaying the subject image P on the monitor screen 17a in 16 or more color colors (S.14). By this processing, the subject image P is displayed as a color image of 16 colors or more on the monitor screen 17a (S.13).

  The system controller 20 is S.I. 6, when the tilt angle of the main body case 11 with respect to the set reference angle is within the allowable angle range, it is determined whether or not the brightness of the subject image P is equal to or less than the second threshold (S.15). The system controller 20 is S.I. 15, when the brightness of the subject image P is less than or equal to the second threshold value, an indicator I display process (S.16), which will be described later, is executed. 17 The system controller 20 is S.I. 15, when the brightness of the subject image P exceeds the second threshold, S.I. 17

  The system controller 20 is S.I. In step 17, it is determined whether the color photographing mode is selected or the single color photographing mode is selected. When the color photographing mode is selected, the system controller 20 performs a calculation for displaying the subject image P as a color image of 16 colors or more on the monitor screen 17a (S.18). By this processing, the subject image P is displayed as a color image of 16 colors or more on the monitor screen 17a (S.13).

    The system controller 20 is S.I. If the single color shooting mode is selected in step 17, it is determined whether the subject image P is displayed as a monochrome image or a sepia image (S.19). The system controller 20 is S.I. If it is determined in 19 that the subject image P is set to be displayed as a black and white image, an operation for displaying the subject image P as a black and white image on the monitor screen 17a is executed (S.20). The system controller 20 is S.I. If it is determined in 19 that the subject image P is set to be displayed as a black and white image, an operation for displaying the subject image P as a sepia image on the monitor screen 17a is executed (S.21). By this processing, the subject image P is displayed on the monitor screen 17a as a monochrome image or a sepia image (S.13).

Therefore, in this embodiment, the following effects are achieved.
a: When the color shooting mode is set Regardless of whether horizontal shooting or vertical shooting is performed, the brightness of the subject image P is equal to or higher than the first threshold, and the tilt angle of the case body 11 is within the allowable angle range. When outside, the brightness of the monitor screen 17a shown in FIG. 5 is set low, and the subject image P is displayed on the monitor screen 17a as a monochrome image or a sepia image. Further, when the tilt angle of the case body 11 is within the allowable angle range, the brightness of the monitor screen 17a remains the original brightness and the subject image P is a color image of 16 colors or more on the monitor screen 17a as shown in FIG. It is displayed as shown in. When shooting is performed in the state shown in FIG. 9, the subject image P is recorded and stored in the memory group 23 as a color captured image of 16 or more colors.

In this way, it is determined whether or not the inclination angle of the case body 11 is within the allowable angle range due to the color change of the subject image P without the indicator I being superimposed on the subject image P of the monitor screen 17a. Therefore, the entire subject image P can be easily recognized during monitoring, and the tilt of the case body 11 can be easily grasped intuitively.
b: When the monochromatic shooting mode is set When the brightness of the subject image P is equal to or higher than the first threshold value regardless of whether horizontal shooting or vertical shooting is performed, and the inclination angle of the case body 11 is within the allowable angle range. When outside, the brightness of the monitor screen 17a is set low, and the subject image P is displayed on the monitor screen 17a as a color image of 16 colors or more. When the tilt angle of the case body 11 is within the allowable angle range, the brightness of the monitor screen 17a remains the original brightness, and the subject image P is displayed on the monitor screen 17a as a monochrome image or a sepia image. . If shooting is performed in this state, the subject image P is recorded and stored in the memory group 23 as a black and white shot image or a sepia shot image.

  Also in this case, whether or not the inclination angle of the main body case 11 is within the allowable angle range due to a change in the color of the subject image P without displaying the indicator I superimposed on the subject image P on the monitor screen 17a. Since the determination can be made, it is possible to easily recognize the entire subject image P during monitoring and to easily grasp the inclination of the main body case 11 intuitively.

  The system controller 20 is S.I. 10, S.M. In the 16 indicator processing, the following processing is executed.

  FIG. 10 shows the indicator I displayed so as to be superimposed on the subject image P on the monitor screen 17a. The indicator I is composed of an array in which a plurality of bar-shaped display frames 30 as the same index bar are spaced apart in the horizontal direction.

  Each bar-shaped display frame 30 is used to display the inclination angle of the case body 11 with respect to the set reference angle. Here, description will be made on the assumption that the setting reference angle of the case body 11 is horizontal shooting reference and is horizontal.

  In FIG. 10, reference numeral 31 denotes a central indicator bar, and the central indicator bar 31 is provided with an instruction frame 33 indicating that it is the center so as to surround the central indicator bar 31 from above and below. Yes.

  In this central index bar 31, here, when the inclination of the case body 11 is centered on 0 degree (horizontal) and is within the allowable angle range, for example, a rectangular area surrounded by the contour line 30a is displayed in green. The Further, when the inclination of the case body 11 is within the allowable angle range, the outline 34 surrounding the rectangular area of the entire array is displayed in green, whereby the inclination of the case body 11 is within the allowable angle range. Is emphasized.

  The rectangular area surrounded by the outline 30a of each of the left and right index bars 30 of the central index bar 31 has an inclination angle of the case body 11 when the tilt angle of the case body 11 is outside the allowable angle range. Correspondingly, it is displayed in orange. For example, when the case body 11 is tilted to the left by a predetermined angle, the right indicator bar 31 'is displayed in orange as shown in FIG.

  According to the indicator I display processing, when the brightness (luminance) of the subject image P is equal to or smaller than the second threshold value, the indicator I is displayed together with the subject image P on the monitor screen 17a. Even when shooting is performed, the inclination of the main body case 11 can be reliably recognized.

  It should be noted that the system controller 20 has the S.P. 3, when vertical shooting is set, when the brightness of the subject image P is greater than or equal to the second threshold and the tilt angle of the case body 11 is within the allowable angle range, as shown in FIG. In addition, the subject image P is displayed without the indicator I being displayed on the monitor screen 17a.
