Abstract: A projection apparatus capable of appropriately performing shift control of a projection image when a posture or a projection direction of a projection lens is changed by rotating the projection lens is provided.

Abstract: An object of the present invention is to provide a projection apparatus capable of appropriately performing control relating to rotation of a projection lens. A projection apparatus according to a first aspect of the present invention includes a housing; a power supply; a control unit; and a projection lens attached to the housing, the projection lens having a holder, a detection unit that detects a rotation state of the holder, and a locking mechanism unit that brings rotation of the holder into a locked state or an unlocked state. The locking mechanism unit does not bring rotation of the holder into the locked state when a rotation state of the holder is other than a specific state. The specific state is a rotation state in which the locking mechanism unit is capable of bringing rotation of the holder into the locked state. When rotation of the holder is not brought into the locked state, the control unit disables an operation relating to the locked state or an operation of turning off the power supply.

Abstract: An object of the present invention is to provide a projection apparatus capable of appropriately performing control relating to a rotation state and/or a movement state of a projection lens. A projection apparatus according to an aspect of the present invention includes a housing; a light source; a control unit; and a projection lens attached to the housing, the projection lens having a holder, a detection unit that detects a rotation state of the holder, an emission optical system, and a locking mechanism unit that brings rotation of the holder into a locked state or an unlocked state. The projection lens is displaceable between a first position at which a rotation state of the holder is a housed state in which the emission optical system faces the housing and a second position at which the emission optical system does not face the housing by rotating the holder. The second position includes an upper position at which the emission optical system faces an upper side in a vertical direction.

Abstract: An object of the present invention is to provide a projection apparatus capable of appropriately performing control relating to rotation of the projection lens. A projection apparatus according to a first aspect of the present invention includes a housing; a power supply; and a projection lens attached to the housing, the projection lens having a holder and a locking mechanism unit that brings rotation of the holder into a locked state or an unlocked state. Rotation of the holder is in the locked state when the power supply has been turned on. With the first aspect, since the power is turned on in a state in which the projection lens is not rotatable, the locked state can be safely unlocked by user's intention and the holder can be rotated.

Abstract: A projection apparatus capable of, when an image input from an external device and an OSD image are rotated by rotation of a projection lens, performing rotation correction suitable for the respective images is provided. A projection apparatus (1) includes a housing; a projection lens (3) that has a holder and that is rotatably attached to the housing; a first rotation position detection unit (70A) and a second rotation position detection unit (70B) that detect rotation states of the holder; a DMD (22B) that outputs, to the projection lens (3), a composite image of a projection image output from an external device and an OSD image including a character output from an internal memory; and a control unit that performs rotation correction on the OSD image and that does not perform rotation correction on the projection image based on detection results of the first rotation position detection unit (70A) and the second rotation position detection unit (70B) when the holder of the projection lens (3) rotates.

Abstract: First and second reception units receive a setting instruction for a first correspondence relationship which is a correspondence relationship between a direction of a first operation performed on a touch-type operation unit and a movement direction in which a list image moves with respect to a screen in response to the first operation, and a second correspondence relationship which is a correspondence relationship between a direction of a second operation performed on a direction instruction key and a movement direction in which the list image moves with respect to the screen in response to the second operation. An information management unit sets the first correspondence relationship and the second correspondence relationship. A command output unit decides the movement direction of the list image with respect to the screen based on the first correspondence relationship or the second correspondence relationship in a case where the first operation or the second operation is performed.

Abstract: A display control unit displays an enlarged image and a guide frame on a screen. First and second reception units (reception unit) receive a setting instruction for a correspondence relationship between an operation direction of a gesture operation and a movement direction of an enlargement display region. An information management unit (setting unit) sets the correspondence relationship in response to the setting instruction. A command output unit (deciding unit) decides a movement direction in a region of a captured image based on the correspondence relationship in a case where the gesture operation is performed. The display control unit moves the enlargement display region in the decided movement direction.
