  The diaphragm / shutter 4 includes a drive circuit (not shown), and operates according to a control signal sent from the CPU 13 by the drive circuit. The diaphragm / shutter 4 controls the amount of light entering from the imaging lens 2. The CCD (imaging device) 5 converts the light of the subject projected through the imaging lens 2 and the aperture / shutter 4 into an electrical signal and outputs the electrical signal to the unit circuit 7. The CCD 5 is driven in accordance with a predetermined frequency timing signal generated by the TG 6.

  The unit circuit 7 includes a CDS (Correlated Double Sampling) circuit that holds the imaging signal output from the CCD 5 by correlated double sampling, an AGC (Automatic Gain Control) circuit that performs automatic gain adjustment of the imaging signal after the sampling, It is composed of an A / D converter that converts an analog imaging signal after automatic gain adjustment into a digital signal. The unit circuit 7 is driven in accordance with a timing signal having a predetermined frequency generated by the TG 6. The imaging signal of the CCD 5 is sent to the image processing unit 8 as a digital signal through the unit circuit 7.

  The image processing unit 8 performs image processing (pixel interpolation processing, γ correction, luminance color difference signal generation, white balance processing, exposure correction processing, etc.) of image data sent from the unit circuit 7, and compression / decompression of image data ( For example, JPEG format, Motion-JPEG format, or MPEG format compression / decompression processing, processing for combining a plurality of captured images, and the like are performed. The image processing unit 8 is driven according to a timing signal having a predetermined frequency generated by the TG 6.

  The CPU 13 is a one-chip microcomputer that controls each part of the head-mounted imaging device 1. In particular, in the present embodiment, the CPU 13 performs still image shooting with the CCD 5, start / stop of video recording, still image shooting in response to an operation on a touch key 18 described later provided in a part of a casing described later. Switch movie shooting, enter / exit sleep mode, etc.

  The DRAM 14 is used as a buffer memory for temporarily storing image data sent to the CPU 13 after being imaged by the CCD 5 and also as a working memory for the CPU 13. The memory 15 stores a program necessary for controlling each part of the digital camera 1 by the CPU 13, data necessary for controlling each part, voice data for voice guidance for notifying the user of a shooting state, and the like. The CPU 13 performs processing according to this program. The flash memory 16 is a recording medium that stores image data captured by the CCD 5.

  The display unit 17 includes a color LCD and its driving circuit, and displays the subject imaged by the CCD 5 as a through image when in the imaging standby state, and from the flash memory 16 or the memory card 20 when reproducing the recorded image. The read and expanded recorded image is displayed. The touch key 18 outputs an operation signal corresponding to the user's touch operation to the CPU 13. The external I / F 19 transmits / receives data to / from an external device such as a personal computer, for example, by transferring captured still images and moving images by wire / wireless.

  The earphone 21 outputs voice guidance (sound data stored in the memory 15) of the shooting situation in accordance with a touch operation on the touch switch under the control of the CPU 13. The microphone 22 collects an external voice at the time of motion shooting and collects a user's voice to control the operation by voice recognition. The LED 23 is turned on as illumination for making up for the shortage of light amount during shooting.

  The angle detection unit 24 includes a mechanical, optical, or electromagnetic sensor, and detects the angle of the case unit in which the lens mechanism in the main body having the rotation mechanism is accommodated. The details of the structure of the head-mounted imaging device 1 will be described later. The acceleration sensor 25 detects the movement of the head-mounted imaging device 1. The CPU 13 automatically switches to a shooting mode in which shooting blur is unlikely to occur in accordance with a detection output (signal corresponding to movement) from the acceleration sensor 25. For example, when the user starts running during shooting, the acceleration sensor 25 detects the movement, so that it may be automatically switched to a high-speed shooting mode in which shooting blurring is difficult. Shooting is possible even when the user is moving around the body, such as sports.

  Although not shown in the drawings, the head-mounted imaging device includes a rechargeable battery, and driving power is supplied to each unit by the battery.

  2 (a), 2 (b), and 3 (a) to 3 (d) are schematic views showing the structure of the head-mounted imaging device according to the present embodiment, and FIG. 4 shows the head according to the present embodiment. It is a schematic diagram which shows the mounting state of a part mounting type imaging device. In addition, the same code | symbol is attached | subjected to the part corresponding to FIG. 2 (a) and 2 (b), the main body is connected to a headband-shaped band portion 30 having a length adjusting function and a rotating hinge 31 positioned at one end of the band portion 30. It consists of a case part 33 in which the mechanism 32 is accommodated. Photographing is performed with the band unit 30 fixed to the head. The band portion 30 is made of an elastic member, and can be attached in conformity to various head shapes, so that anyone can easily attach it. When used, it can be used with glasses.

  At the time of shooting, as shown in FIGS. 3A, 3B, and 4, the case portion 32 in which the lens mechanism 33 is accommodated is rotated 90 degrees forward about the rotary hinge 31 so that the lens faces the face. Protrude forward. The case part 32 can be rotated 90 degrees left and right with respect to the band part 30 and can be photographed (attached) even if the earphone 21 is brought to either the left or right ear, and is right-handed. The touch key 18 can be operated regardless of left-handed.

  In this state, as shown in FIG. 4, the lens mechanism 33 is laid out so as to be close to the eye level. It is also possible to adjust the horizontal angle of view of the lens using a sensor. As shown in FIGS. 3C and 3D, the case unit 32 is provided with the lens mechanism 33, the microphone 22, and the LED 23 described above. Further, since the band portion 30 has a headband shape, the hair is bundled and the lens mechanism 33 protrudes forward so that the lens itself is less likely to be covered with hair. The case part 32 can be raised and stored in the band part 30 when not in use, thereby preventing the lens from being stained or damaged.

  The operation can be selected from a touch operation of the touch key 18 arranged on the side surface of the case portion 32, a voice recognition operation for recognizing voice, and a wireless key operation by a remote controller (not shown). For the operation, the shooting situation is guided in real time by voice from the earphone 21 laid out inside the band unit 30.

B. Operation of Embodiment Next, the operation of the above-described embodiment will be described.
FIG. 5 is a flowchart for explaining the operation of the head-mounted imaging device according to the present embodiment. First, when the user wears the band unit 30 of the head-mounted image pickup device 1 on the head and rotates the case unit 32 by 90 degrees so that the lens protrudes in front of the face, the power of the main body is turned on. Thus, the flowchart shown in FIG.

  First, when the power is turned on, the CPU 13 sets shooting parameters, a shooting mode (still image shooting mode or moving image shooting mode), and the like (step S10). Next, it is determined whether or not a touch operation has been performed on the touch key 18 (step S12). If the touch operation is not detected (NO in step S12), whether or not a state in which the touch operation is not detected has elapsed for a predetermined time or more. It is determined whether or not (step S14). If the state in which the touch operation is not detected is less than the predetermined time (NO in step S14), the process returns to step S12.

  On the other hand, when the state in which the touch operation is not detected has passed for a predetermined time or longer, only the power supply to the mechanism necessary for the touch detection operation is left, and the sleep mode is entered to cut off the power supply to the other (step S16). The fact that the mode has been shifted to the three mode is output from the earphone 21 by voice guidance (step S18). After the transition to the sleep mode, it is determined whether or not there has been a touch operation on the touch key 18 (step S20). If there is no touch operation on the touch key 18 (NO in step S20), the sleep mode is continued. On the other hand, if there is a touch operation on the touch key 18 (YES in step S20), the sleep mode is canceled (step S22), and the fact that the three mode is canceled is output from the earphone 21 by voice guidance (step S24). Return to S12.

  On the other hand, if a touch operation on the touch key 18 is detected in step S12 (YES in step S12), it is determined whether or not the touch operation is a long press (for a predetermined time or more, for example, about 2 seconds). Judgment is made (step S26). If it is a long press (YES in step S26), switching between the still image shooting mode and the moving image shooting mode is executed (step S28), and the fact that the shooting mode has been switched is output from the earphone 21 by voice guidance. (Step S30), the process returns to Step S12.

  On the other hand, when the touch operation on the touch key 18 is a light touch (short-time touch) (NO in step S26), if the still image shooting mode is selected, a still image is shot. If so, start recording, stop if recording is in progress (step S32), output the operation from the earphone 21 by voice guidance (step S34), and return to step S12.

  Since the band part 30 and the case part 32 are connected, the angle of view of the lens follows the movement of the head, and the entire field of view can be photographed and recorded with the wide-angle lens without looking at the liquid crystal finder. During shooting, the image is recorded with a wide angle and high image quality, and the image data is trimmed (enlarged / reduced) after shooting to obtain an image with a desired angle of view.

  Further, since it is possible to shoot with the head set, it is not necessary to hold a camera, and it is possible to shoot with both hands free. For example, it is possible to take a picture while the vehicle is being operated or when the photographer's hands are covered with luggage or tools. It is also possible to take a picture even when the photographer moves his body throughout the body, such as sports.

  According to the above-described embodiment, the case unit 32 in which the lens mechanism 33 is accommodated is rotated by 90 degrees with respect to the band unit 30, and the power is turned on only by protruding the lens to the front of the face. The power can be turned off simply by storing it, and even a beginner can easily operate it.

  In addition, since a shooting mode is switched and shooting start / stop is instructed in response to a touch operation of a touch key disposed on the case unit 32 in which the lens mechanism 33 is housed, it is easy even for beginners. Can be operated.

  In addition, since operation is performed from the earphone 21 laid out on the inner side of the band unit 30 and the shooting situation is guided in real time by voice, even a beginner can easily perform the operation.

  In the embodiment described above, the shooting mode is switched by long-pressing the touch key 18. However, the present invention is not limited to this. For example, in addition to the switching of the shooting mode in the setting mode, the shooting image quality is switched to the setting mode. You may make it switch to a transfer mode to a mobile liquid crystal device such as a personal computer or a mobile phone.

  Further, regarding detailed settings and management editing of captured images, the main body may be connected to a personal computer via an external I / F (USB or wireless) 19 and may be performed using a dedicated application. Further, it is possible to exchange images and moving images between the head-mounted imaging devices without using a personal computer or the like. The charging of the main body may be performed via the external I / F (USB) 19 or may be performed by connecting to a dedicated cradle having various external terminals.
