1. An intraoral camera system comprising:
an imaging unit that includes a handle, a head, and a neck and captures an image of a tooth inside a mouth to generate image data, the head including an image sensor that generates the image data, and the neck connecting the handle to the head;
a sensor that detects an orientation of the imaging unit;
an image processor that performs image processing for the image data according to the orientation of the imaging unit detected by the sensor; and
a display that displays the image data that has undergone the image processing,
wherein if a first angle formed by an imaging plane perpendicular to an optical axis of the imaging unit and a first direction that is a vertically upward direction along a vertical axis is less than a predetermined second angle,
the image processor rotates the 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 the handle toward the head.
