    Abstract: A projection apparatus includes a light source, a light modulation portion, a first mirror, a second mirror, a third mirror, a fourth mirror, and a projection optical system. The light source performs irradiation with light. The light modulation portion modulates the light from the light source. The first mirror, the second mirror, the third mirror, and the fourth mirror reflect an optical image modulated by the light modulation portion. The projection optical system projects the optical image reflected by the first mirror, the second mirror, the third mirror, and the fourth mirror to a projection surface of a projection target object. The first mirror, the second mirror, the third mirror, and the fourth mirror are arranged between the light modulation portion and the projection optical system.

    Abstract: Provided are an imaging apparatus, an imaging method, and a program capable of accurately and simply controlling a movement sensitivity of an index displayed on a finder monitor to a sensitivity desired by a user by using a touch panel installed on a rear monitor. The imaging apparatus (10) has a finder that includes the finder monitor (13), the touch panel (31) that receives a swipe operation for moving the index, and an image processing unit (24). The image processing unit (24) includes a sensitivity setting unit that sets a first sensitivity for coarsely moving the index by the swipe operation or a second sensitivity for finely moving the index by detecting a contact operation to the touch panel in the swipe operation, and a movement control unit that moves the index on the basis of the swipe operation on the touch panel and the sensitivity set by the sensitivity setting unit.
