Abstract
A projector includes a lens adjustment mechanism that performs a predetermined adjustment operation for a projection lens, an input selection unit that selects one input terminal from plurality of input terminals provided in the input terminal unit according to a predetermined operation, an adjustment value storage unit that stores lens adjustment values by linking to the type of the input terminal, an adjustment value acquisition unit that acquires, from the adjustment value storage unit, the lens adjustment values corresponding to the type of the selected input terminal when the predetermined operation is received, and an adjustment control unit that causes the lens adjustment mechanism to perform a lens adjustment operation based on the acquired lens adjustment values.
Claims16
A projector comprising:
- a light source;
- a light modulation device that modulates light emitted from the light source into image light according to an image signal;
- a projection lens that projects the image light modulated by the light modulation device;
- a lens adjustment mechanism that performs a predetermined adjustment operation for the projection lens;
- an input terminal unit that includes a plurality of input terminals into which the image signal is input;
- an operation reception unit that receives a predetermined operation;
- an input selection unit that selects one input terminal from the plurality of input terminals provided in the input terminal unit according to the predetermined operation that the operation reception unit receives;
- an adjustment value storage unit that stores lens adjustment values for adjusting the lens adjustment mechanism by linking to the types of the input terminals;
- an adjustment value acquisition unit that acquires, from the adjustment value storage unit, the lens adjustment values corresponding to the type of the input terminal selected by the input selection unit when the operation reception unit receives the predetermined operation;
- and
- an adjustment control unit that causes the lens adjustment mechanism to perform a lens adjustment operation based on the lens adjustment values acquired by the adjustment value acquisition unit.
A control method of a projector that includes a light source, a light modulation device that modulates light emitted from the light source into image light according to an image signal, a projection lens that projects the image light modulated by the light modulation device, a lens adjustment mechanism that performs a predetermined adjustment operation for the projection lens, an input terminal unit that includes a plurality of input terminals into which the image signal is input, an input selection unit that selects one input terminal from the plurality of input terminals provided in the input terminal unit, and an adjustment value storage unit that stores lens adjustment values for adjusting the lens adjustment mechanism by linking to the types of the input terminals, the method comprising:
- receiving a predetermined operation;
- causing the input selection unit to select one input terminal from the plurality of input terminals provided in the input terminal unit according to the predetermined operation received in the receiving;
- acquiring, from the adjustment value storage unit, the lens adjustment values corresponding to the type of the input terminal selected by the input selection unit when the predetermined operation is received in the receiving;
- and
- controlling adjustment by causing the lens adjustment mechanism to perform a lens adjustment operation based on the lens adjustment values acquired in the acquiring.
