SW1 is a half-push switch that is linked to the first stroke of the release button, and SW2 is a full-push switch that is linked to the second stroke of the release button.

As shown by the coordinate axes in FIG. 1, the tilt sensor 36 sets the rotation angle of the camera body 100a for a predetermined time (for example, 10 ms) as a positive direction when the clockwise position is rotated about the XYZ axes with the positive position as a reference. θx, θy, and θz are detected. The tilt sensor 36 outputs the measured rotation angle value to the MCU 101. The MCU 101 calculates the combined tilt angle θ of the camera 100. Here, since the angle in the Z-axis direction does not directly contribute to the movement of the subject image in the viewfinder, the combined tilt angle θ is calculated as follows using rotation angles θx and θy of two axes other than the Z-axis. Calculated.

θ = √ {(θx) ² + (θy) ² } (1)

  In this embodiment, the camera 100 has 51 ranging areas. FIG. 4 is a diagram showing 51 total distance measuring area displays 200 in the finder visual field 57a. In FIG. 4, all 51 ranging area displays 200 are shown. However, all the ranging area displays 200 are not actually lit in the finder field 57a, and the selected ranging areas are displayed. Only the selected ranging area display 200a is lit as shown in FIG. The selected ranging area display 200a does not light for a moment when a release button (not shown) is pressed, but once selected, it continues to light at that position until changed. In addition, the selected distance measuring area display 200a automatically tracks and moves the subject captured by the photographer when the subject deviates from the selected distance measuring area display 200a. This amount of movement is output to the MCU 101.

Returning to FIG. 2, the superimpose display control circuit 111 is a circuit that performs control when the selected ranging area display 200 a is displayed superimposed on the subject image (superimpose) in the finder visual field 57 a. The superimpose display control circuit 111 controls the transmissive liquid crystal 72 that displays the selected ranging area display 200a in the finder visual field 57a to move the selected ranging area display 200a, and also moves the camera 100 described above. Based on the angular velocity ω _cam , the moving angular velocity ω _VR of the photographic lens 10, and the amount of movement of the selected distance measuring area display 200 a, the brightness of the LED 74 is changed, and the EV value of the selected distance measuring area display 200 a is changed to the duty of the current flowing through the LED 74. Correction is made by adjusting the ratio.

The control of the EV value of the selected ranging area display 200a by the superimpose display control circuit 111 will be described in more detail. First, the superimpose display control circuit 111 uses the initial value of the EV value of the selected distance measuring area display 200a as the luminance information of the subject image in the area overlapping the selected distance measuring area display 200a measured by the photometric sensor 62. Is set to EV ₀ which is the optimum EV value calculated in (1).

表１において、Ｔｈ_θはカメラ１００の合成傾斜角度θの閾値、Ｔｈ_ｃａｍはω_ｃａｍの閾値、Ｔｈ_ＶＲはω_ＶＲの閾値である。また、ＥＶ_ｃｏｒは補正後の選択測距エリア表示２００ａのＥＶ値、ＥＶ_０は補正前の選択測距エリア表示２００ａのＥＶ値、ΔＥＶは選択測距エリア表示２００ａの補正量であり、ΔＥＶ_ｐｕｒ＞ΔＥＶ_ｍｏｖｅである。 Next, as shown in Table 1 below, the EV value of the selected distance measuring area display 200a is based on the moving angular speed ω _cam of the camera 100, the moving angular speed ω _VR of the photographing lens 10, and the amount of movement of the selected distance measuring area display 200a. to correct.

In Table 1, Th _θ is a threshold value of the combined tilt angle θ of the camera 100, Th _cam is a threshold value of ω _cam , and Th _VR is a threshold value of ω _VR . EV _cor is the EV value of the selected ranging area display 200a after correction, EV ₀ is the EV value of the selected ranging area display 200a before correction, ΔEV is the correction amount of the selected ranging area display 200a, and ΔEV _pur > ΔEV _move .

FIG. 5 is a flowchart showing correction amount determination processing in the superimpose display control circuit 111 for achieving the correction of Table 1.
As described above, the selected ranging area display 200a automatically moves by tracking the subject captured by the photographer when the subject is removed, and the movement is output to the MCU 101. First, the superimpose display control circuit 111 determines whether or not the selected ranging area display 200a has moved within the finder based on a signal from the MCU 101 (S201).
If the selected ranging area display 200a is moving (S201, Yes), it is determined whether or not the combined tilt angle θ of the camera 100 calculated by Expression (1) is _{equal to} or greater than a predetermined threshold Th _θ (S202).
When the combined tilt angle θ of the camera 100 is greater than or equal to the predetermined threshold Th _θ (S202, Yes), it is determined whether or not ω _cam calculated by Equation (2) is greater than or equal to the threshold Th _cam (S203).
When ω _cam is equal to or greater than the threshold Th _cam (S203, Yes), correction is performed to make the EV value of the selected ranging area display 200a brighter than EV ₀ (S204). The correction value at this time is ΔEV _pur . By this correction, the selected ranging area display 200a becomes brighter than the normal case where the subject is not moving, and the selected ranging area display 200a is not easily lost even if the subject is moving.

In S203, when ω _cam is smaller than the threshold Th _cam (S203, No), it is determined whether or not ω _VR calculated by Expression (3) is equal to or greater than the threshold Th _VR (S205).
When ω _VR is equal to or greater than the threshold Th _VR (S205, Yes), correction is performed by ΔEV _pur (S204). Also in this case, the selected ranging area display 200a is brighter than the normal case where the subject is not moving, and the selected ranging area display 200a is not easily lost even if the subject is moving.

When the combined tilt angle θ of the camera 100 is smaller than the predetermined threshold Th _θ (S202, No), correction is performed by ΔEV _move (S206).
In S202, when the combined tilt angle θ of the camera 100 is smaller than the predetermined threshold Th _θ (S202, No), correction is performed by ΔEV _move (S206).
Further, even in the case where ω _VR is smaller than the threshold Th _{VR in} S205 (S205, No), correction is performed by ΔEV _move (S206).
Also in these cases, the selected ranging area display 200a is brighter than the normal case where the subject is not moving, and the selected ranging area display 200a is less likely to be lost even if the subject is moving. Here, ΔEV _move is a value smaller than ΔEV _pur . This is because, in this case, since the camera 100 is moving, but the combined tilt angle θ, which is the amount of movement, is smaller than a predetermined threshold Th _θ , the correction amount is smaller than ΔEV _pur when θ is equal to or larger than the threshold Th _{θ. This} is because it is considered that the selected ranging area display 200a is not lost even if it is moved. By brightening only the necessary amount in this way, it is possible to reduce discomfort caused by the selected ranging area display 200a being too bright, and to reduce power consumption.

If the selected ranging area display 200a has not moved in S201 (S201, No), it is determined whether the combined tilt angle θ of the camera 100 is _{equal to} or greater than a predetermined threshold Th _θ (S207).
If the combined tilt angle θ of the camera 100 is greater than or equal to the predetermined threshold Th _θ (S207, Yes), it is determined whether ω _cam is greater than or equal to the threshold Th _cam (S208).
If ω _cam is greater than or equal to the threshold Th _cam (S208, Yes), correction is performed (S206). The correction value at this time is ΔEV _move . Also in this case, the selected ranging area display 200a is brighter than the normal case where the subject is not moving, and the selected ranging area display 200a is not easily lost even if the subject is moving.

If ω _cam is smaller than the threshold Th _{cam in} S208 (S208, No), it is determined whether ω _VR is greater than or equal to the threshold Th _VR (S209).
When ω _VR is equal to or greater than the threshold Th _VR (S209, Yes), correction is performed by ΔEV _move (S206). Thereby, the selected ranging area display 200a becomes brighter than the normal case where the subject is not moving, and it is difficult to lose sight of the selected ranging area display 200a even if the subject is moving.

When the combined tilt angle θ of the camera 100 is smaller than the predetermined threshold Th _θ (S207, No) or when ω _VR is smaller than the thresholds Th _cam and Th _VR (S209, No), the amount of movement of the subject is the selected ranging area. Since it is considered that the display 200a is not lost, correction is not performed (S210).

As described above, this embodiment has the following effects.
(1) When the camera 100 or the photographing lens 10 is moved by moving the subject, the selected distance measuring area display 200a is harder to see than when the subject is stationary. However, according to the present embodiment, when the camera 100 or the photographing lens 10 is moving, the selected distance measuring area display 200a is displayed brightly. Therefore, it is difficult to lose sight of the selected ranging area display 200a.
(2) In addition to the movement of the camera 100 and the photographing lens 10, when the selected distance measuring area display 200a is moved within the viewfinder visual field 57a, the selected distance measuring area display 200a is more difficult to see. However, according to the present embodiment, it is determined whether or not the selected ranging area display 200a is moving, and when it is moving, the correction amount is made larger overall than when it is not moving. For this reason, when the selected ranging area display 200a is moving, it is difficult to lose sight of the selected ranging area display 200a.
(3) The possibility of losing sight of the selected ranging area display 200a differs depending not only on the speed but also on the moving amount θ of the camera. For this reason, first, θ is classified according to the threshold Th _θ , and when θ is large, the correction amount is increased, so that the selected ranging area display 200a is less likely to be lost.
(4) By providing threshold values for the moving speed ω _{cam of the} camera and the moving speed ω _VR of the lens barrel, and increasing the correction amount when the threshold value is exceeded, the selected distance measuring area display 200a is less likely to be lost. .

Only the presence / absence of movement of the selected ranging area display 200a in the finder visual field 57a may be detected, and whether to perform correction may be determined based on the result. Alternatively, only the presence or absence of movement of the camera 100 may be detected, and it may be determined whether to perform correction based on the result.

For example, a separate acceleration sensor or the like may be provided in the camera 100. Further, for example, the movement of a focusing area provided in 3D tracking, dynamic AF, a face recognition sensor, or the like may be detected. Further, correction may be made when a mode that keeps focusing while the subject is chased is selected instead of the mode in which the focus is fixed by the release.

  (3) In this embodiment, the correction amount is determined based on the EV value. However, if it is clear that the processing results are the same, another value (for example, BV value) may be used. .

(4) In the present embodiment, the correction amount is set in three stages of ΔEV _pur , ΔEV _move , and 0 according to the movement of the ranging area on the screen and the movement amount of the camera or the lens barrel, but is not limited to this. However, it may be more than this, and it may be a two-stage of correcting or not.
