Abstract
An intra-oral imaging device includes: an imager that detects radiation transmitted through an object while being placed in an oral cavity; and a controller that controls the imager while being placed outside the oral cavity. The imager includes an image sensor including a plurality of pixels for acquiring an image of the object. While power is being supplied to the controller, the controller supplies power to the image sensor in an imaging period during which the image sensor performs imaging and stops supplying the power to the image sensor in a standby period during which the image sensor is on standby.
Claims6
An intra-oral imaging device, comprising:
- an imager that detects radiation transmitted through an object while being placed in an oral cavity;
- and
- a controller that controls the imager while being placed outside the oral cavity,
- wherein the imager includes:
- (i) an image sensor including a plurality of imaging pixels for acquiring an image of the object and a monitoring pixel for monitoring a dose of the radiation;
- or
- (ii) an image sensor including a plurality of imaging pixels for acquiring an image of the object and a light receiving element including a monitoring pixel for monitoring a dose of the radiation, and
- while power is being supplied to the controller, the controller supplies power to the image sensor in an imaging period during which the image sensor performs imaging and while power is being supplied to the controller, the controller stops supplying the power to the image sensor in a standby period during which the image sensor is on standby.
