A shutter button 11 is provided on the upper surface of the digital camera 2.
[0009]
As shown in FIG. 2, the rear surface of the digital camera 2 includes an eyepiece finder window 12, an LCD 13, a mode selection button 14, and an operation button 15 that constitute the finder 7. The operation mode selected by the mode selection button 14 includes a shooting mode for shooting a still image, a playback mode for playing back a shot image, a moving image mode for shooting a moving image, and the like.
[0010]
As shown in FIG. 3A, the digital camera 2 includes a mercury switch 16 that detects that the optical axis L of the photographing lens 5 is tilted upward with respect to the horizontal direction. Although not shown in detail, the mercury switch 16 encloses mercury 18 in a tubular glass container 17 and further passes two lead wires 19a and 19b. The mercury 18 is connected to both ends of the lead wires 19a and 19b. It is moved between the contact position and the position away from these positions. When the lead terminals 19a and 19b come into contact with the mercury 18, a detection signal is sent out. Since the glass container 17 has an elliptical shape, the inclination angle until the mercury switch 16 is inclined and the lead wires 19a and 19b come into contact with each other is large.
[0011]
The mercury switch 16 is fixed to the lens barrel 6 in the digital camera 2 and is arranged so that the central axis 20 of the glass container 17 is parallel to the optical axis L. One end of the glass container 17 provided with the lead wires 19 a and 19 b is disposed on the back side of the digital camera 2. As shown in FIG. 3B, when the optical axis direction is tilted upward by a predetermined angle with respect to the horizontal direction, the mercury 18 comes into contact with the lead terminals 19a and 19b and sends out a detection signal. The mercury 18 is in contact with the lead wires 19a and 19b while the optical axis L is included in a predetermined direction range in which the optical axis L is set, and sends a detection signal. The predetermined direction range is, for example, arranged so that a detection signal is transmitted from the mercury switch 16 when the optical axis L is inclined 30 ° to 150 ° upward with respect to the horizontal direction. Is not limited to this.
[0012]
FIG. 4 shows an outline of the electrical configuration of the digital camera 2. The system controller 21 controls each part of the digital camera 2 according to a control program stored in the ROM 22. The photographing unit 24 includes a CCD image sensor, a CDS (correlated double sampling circuit), an amplifier, an A / D converter, and the like. The subject light from the photographing lens 5 is photoelectrically converted by a CCD image sensor to be converted into an analog photographing signal. The analog photographing signal is converted into digital data by an A / D converter and then sent to the image processing circuit 25. The image processing circuit 25 performs various signal corrections such as gamma correction, sharpness correction, and contrast correction on the image data sent from the photographing unit 24. The image data subjected to these various signal corrections is recorded in the memory card 26.
[0013]
When the shutter button 11 is pressed, the mercury switch 16 detects whether the optical axis L is tilted upward by a predetermined angle with respect to the horizontal direction. When the photographing lens 5 is tilted upward by a predetermined angle or more, a detection signal from the mercury switch 16 is sent to the determination unit 30 of the system controller 21 via the data bus 28. The determination unit 30 determines whether or not the optical axis L is included in the predetermined direction range. When the determination unit 30 receives the detection signal from the mercury switch 16, it determines that the optical axis L is included in the predetermined direction range, issues a warning from the buzzer 32, and sends a signal to the photographing unit 24 to prohibit photographing. When the shutter button 11 is pressed and no detection signal is sent from the mercury switch 16 to the determination unit 30, normal shooting is performed.
[0014]
The operation of the above embodiment will be described with reference to FIG. When the photographer shoots a still image with the digital camera 2, when the shutter button 11 is pressed, the mercury switch 16 detects whether the optical axis L is inclined upward by a predetermined angle with respect to the horizontal direction. To do. When it is detected that the optical axis L is tilted by a predetermined angle or more, the determination unit 30 determines whether or not the optical axis L is included in the predetermined direction range. If the optical axis L is included in the predetermined direction range, it is determined that the photographing lens 5 is facing upward so that voyeurism is possible, and an alarm sound is emitted from the buzzer 32 to prohibit photographing. If it is determined that the optical axis L is not included in the predetermined direction range, the photographing lens 5 does not face upward, and normal photographing is performed.
[0015]
Even when moving image shooting is performed in the moving image mode of the digital camera 2, as shown in FIG. 6, when moving image shooting is started by pressing the shutter button 11, the mercury switch 16 causes the optical axis L to be in the horizontal direction. Whether it is tilted upward by a predetermined angle or more is detected. If the determination unit 30 determines that the optical axis L is included in the predetermined direction range, the buzzer 32 issues an alarm and prohibits photographing. Note that the detection of the optical axis direction and the determination of whether or not it is included in the predetermined direction range are always performed during moving image shooting.
[0016]
In the above embodiment, when it is detected that the optical axis L is included in the predetermined direction range, the buzzer 32 warns and prohibits photographing. However, as shown in FIG. By providing an eyepiece detection sensor 34 for detecting use in the finder 7 of the digital camera 36, the prohibition of alarm or the prohibition of photographing may be canceled. The eyepiece detection sensor 34 detects whether or not the photographer is using the finder 7 to visually recognize the subject. As the eyepiece detection sensor 34 , for example, a gaze detection sensor that detects the gaze of the photographer, a lens detection sensor that detects a crystalline lens, an iris sensor, or the like is used. When the shutter button 11 is pressed, the optical axis L is detected by the mercury switch 16, and it is determined that the optical axis L is included in the predetermined direction range, whether the photographer uses the finder 7 by the eyepiece detection sensor 34. Whether or not is detected. When it is detected that the subject is visually recognized using the finder 7, a signal is sent to the determination unit 30 to prohibit the alarm and cancel the photographing prohibition. Note that the eyepiece detection sensor 34 is not limited to the above-described sensor, and may be any sensor that can detect that the photographer is surely photographing using the finder 7. Further, the eyepiece detection sensor 34 is not limited to the inside of the finder 7 and may be provided in the vicinity of the finder 7.
[0017]
The operation of the above embodiment will be described with reference to FIG. When the mercury switch 16 detects that the optical axis L is tilted upward by a predetermined angle or more with respect to the horizontal direction and the determination unit 30 determines that the optical axis L is included in the predetermined direction range, the eyepiece detection sensor 34 detects the photographer. Whether or not the finder 7 is being used is detected. When it is detected that the finder 7 is being used, normal shooting is performed. If it is not detected that the finder 7 is being used, it is determined that the taking lens 5 is facing upward so as to enable voyeurism, and an alarm is issued from the buzzer 32 to prohibit photographing.
[0018]
Also, as shown in FIG. 9, when the digital camera 36 takes a moving picture, the direction in which the optical axis L is tilted is detected by the mercury switch 16 as in the case of the still picture shooting shown in FIG. If it is determined at 30 that the image is included in the predetermined direction range, the eyepiece detection sensor 34 detects whether or not the finder 7 is being used. When it is detected that the finder 7 is being used, moving image shooting is performed. When the finder 7 is not being used, an alarm is issued from the buzzer 32 and shooting is prohibited. It should be noted that detection by the mercury switch 16 and the eyepiece detection sensor 34 and determination of whether or not included in the predetermined direction range are always performed during photographing. If it is detected that the optical axis L is included in the predetermined direction range, and the use of the finder 7 is not detected in the middle, an alarm is issued at that time and the moving image shooting is stopped. .
[0019]
In the above-described embodiment, the eyepiece detection sensor 34 is provided and the prohibition of alarm or the prohibition of photographing is performed. However, as shown in FIG. 10, the ground on which the digital camera 2 is held instead of the eyepiece detection sensor 34 is provided. Alternatively, a distance measuring sensor 37 that detects the height from the floor may be provided on the back surface of the digital camera 2. The distance measuring sensor 37 is provided on the back surface of the digital camera 38, and when the determination unit 30 detects that the direction of the optical axis L is included in the predetermined direction range, the ground on which the digital camera 38 is held. Alternatively, the height from the floor surface is detected. If the detected height is equal to or higher than a predetermined height set in advance, it is determined that the photographing is not upward from a low angle where voyeurism is possible, and the prohibition of alarm and the prohibition of photographing are performed. Note that the distance measuring sensor 37 measures the distance by radiating ultrasonic waves, microwaves, millimeter waves, light, and receives the reflected wave, and measures the distance, or uses the principle of triangulation. Used. Further, although the distance measuring sensor 37 is provided on the back surface of the digital camera 2, it may be a place where the height from the ground surface or the floor surface can be reliably detected when the optical axis L is directed in the predetermined direction range.
[0020]
The operation of the above embodiment will be described with reference to FIG. When the mercury switch 16 and the determination unit 30 determine that the direction of the optical axis L is included in the predetermined direction range, the distance sensor 37 detects the height from the ground or floor on which the digital camera 38 is held. The When the detected height is equal to or higher than a predetermined height (for example, 1 m) set in advance, normal shooting is performed. If it is lower than the predetermined height, it is determined that the photographic lens 5 is directed upward from a low angle at which voyeurism is possible, an alarm is issued from the buzzer 32 , and photographing is prohibited.
[0021]
Further, even when the moving image of the digital camera 38 as shown in FIG. 12, similarly to the still image shooting shown in FIG. 11, the direction of the optical axis L is determined to be included in a predetermined direction range, measuring The distance sensor 37 detects the height from the ground or floor on which the digital camera 38 is held. If the optical axis direction is included in the predetermined direction range and the detected height is greater than or equal to the predetermined height, video shooting is performed, and if the detected height is lower than the predetermined height, an alarm is issued. Shooting is canceled.
[0022]
Although the mercury switch 16 is used to detect the optical axis direction, the optical axis direction may be detected using an inclination sensor, an acceleration sensor, or the like. Further, in the digital cameras 2, 36, and 38 of the above embodiment, the alarm and the photographing prohibition are performed together, but only one of the alarm and the photographing prohibition may be performed. Further, although the eyepiece detection sensor 34 and the distance measuring sensor 37 are provided separately, they may be provided together. Moreover, since the direction of the optical axis of the photographing lens 5 is detected to prevent voyeurism, voyeurism can be prevented even in a portable device that can shoot only by rotating the camera unit from the portable device body.
[0023]
In the embodiment of the present invention, the digital camera has been described. However, the present invention is not necessarily limited to the digital camera, and may be used for a silver salt camera, a video camera, a camera-equipped mobile phone, and the like.
