Abstract: An intraoral camera system includes an imaging unit that includes a handle, a head including an image sensor for generating image data, and a neck connecting the handle and the head and generates the image data, a position sensor that detects the orientation of the imaging unit; a signal processor that performs signal processing using the orientation of the imaging unit detected by the position sensor, and a display that displays the image data. The signal processor obtains the initial orientation of the imaging unit which is a predetermined orientation of the imaging unit, and performs the signal processing by treating a first direction from the handle toward the head in the initial orientation as a second direction that is a vertically upward direction parallel to a vertical axis.

Abstract: Imaging apparatus (100) includes selectors (115, 120) that select sound signals having a set number of channels, and a control unit. When a number of channels is set to two at time of recording sound signals, the control unit, according to a first format, records sound data generated based on selected sound signals for two channels, on one sound track included in a video file. When the number of channels is set to four, the control unit, does not record two pieces of sound data respectively on two sound tracks included in one video file in accordance with the first format.

Abstract: An imaging device includes an image pickup element that captures an object image to generate image data, a sensor holder that holds the image pickup element, a sensor driver that moves the sensor holder in a plane orthogonal to an optical axis, a fixing mechanism that mechanically fixes the sensor holder at a predetermined position, and a controller that controls the fixing mechanism based on a signal indicating a degree of displacement of the image pickup element due to an external force.

Abstract: An image processing method includes: obtaining a first RGB image generated by capturing an image of a tooth and dental plaque that are fluorescing in response to exposure to light including a blue-light wavelength range; and generating a second RGB image by performing, for the first RGB image, image processing including first image processing. In the first image processing, the gains of at least two color components among the red component, the green component, and the blue component of an RGB image to be processed are adjusted so as to equalize the first red pixel average value of red pixel values, the first green pixel average value of green pixel values, and the first blue pixel average value of blue pixel values, the red pixel values, the green pixel values, and the blue pixel values being the pixel values of first pixels corresponding to the tooth.

Abstract: A digital camera includes common terminal 12, mode dial 10, and function setting unit 140. Mode dial 10 is capable of setting a certain photography mode from among a plurality of photography modes including a moving image photography mode and a still image photography mode. Function setting unit 140 performs a setting so as to, when mode dial 10 sets the certain photography mode to the moving image photography mode, achieve a first function using common terminal 12, and, when mode dial 10 sets the certain photography mode to the still image photography mode, achieve a second function using common terminal 12. Function setting unit 140 does not achieve the second function in the moving image photography mode, and does not achieve the first function in the still image photography mode.

Abstract: An intraoral camera includes an imaging unit, an illuminator, and an illumination controller. The imaging unit generates image data by capturing an image of a tooth inside the mouth of a user. The illuminator illuminates the tooth. The illumination controller controls at least one of the illumination intensity or the color temperature of the illuminator to bring the color temperature of reflected light from the tooth that is based on the image data, closer to a target color temperature based on the second color temperature of the illuminator.

Abstract: An intraoral camera system includes an imaging unit and an image determination unit. The imaging unit generates an image data item showing a target tooth for image capturing inside a mouth. The image determination unit defines two-dimensional plane coordinates for the image data item generated by the imaging unit and extracts the position coordinates of the outline of the target tooth from the entire imaging area of the imaging unit. When a part of the outline of the target tooth is outside an effective area set inside the entire imaging area of the imaging unit, the image determination unit determines that the target tooth extends beyond the effective area.

Abstract: An intraoral camera system includes an imaging unit and an image processor. If a first angle formed by an imaging plane perpendicular to the optical axis of the imaging unit and a first direction that is the vertically upward direction along a vertical axis is less than a predetermined second angle, the image processor rotates image data to cause the vertically upward direction along the vertical axis to coincide with an upward direction of an image by rotating the image data by a third angle formed by the first direction and a second direction from a handle toward a head.
