Projector, projection method and storage medium in which projection method is stored
A projection system is provided which includes a projection lens and a spatial optical modulation device (SOM) for projecting an image in response to an inputted picture signal. A control unit enables the selection, via an image adjustment menu, of at least one of a rotational deformation adjustment in which a projected image is rotated and a keystone deformation adjustment in which the projected image is deformed into a rectangle, and the control unit applies a rotational deformation adjustment and a keystone deformation adjustment to the projected image based on an item selected in the image adjustment menu in response to a deformation indication inputted from a keys/indicators unit, so as to deform the projected image.
1. A projector comprising:
a projection unit which projects an image in response to an inputted image signal;
a detection unit which detects an inclined angle of the projector;
a calculation unit which calculates a rotational adjustment amount for the projected image based on the detected inclined angle;
a rotational deformation unit which rotationally deforms the projected image in accordance with the calculated rotational adjustment amount; and
a movement detector which detects vibrations generated when a setting position of the protector is changed;
wherein the rotational adjustment amount is calculated by the calculation unit and the projected image is rotationally deformed by the rotational deformation unit when power is supplied to the projector and vibrations are detected by the movement detector.
2. A projector as set forth in claim 1 , further comprising a keystone deformation unit which deforms the projected image that has been rotationally deformed by the rotational deformation unit into a rectangle.
3. A projector as set forth in claim 1 , further comprising a deformation setting unit which sets whether or not to execute the rotational deformation on the projected image by the rotational deformation unit, wherein the rotational deformation unit executes the rotational deformation when the execution of the rotational deformation is set by the deformation setting unit.
4. A projection method for projecting an image using a projector comprising:
projecting the image in response to an inputted image signal;
detecting an inclined angle of the projector;
calculating a rotational adjustment amount for the projected image based on the detected inclined angle;
rotationally deforming the projected image in accordance with the calculated rotational adjustment amount; and
detecting vibrations generated when a setting position of the projector is changed;
wherein, when power is supplied to the projector and vibrations are detected, the rotational adjustment amount is calculated and the projected image is rotationally deformed.
5. A computer-readable recording medium having a program stored thereon that is executable by a control unit of a projector for projecting an image, to cause the control unit to control the projector to perform functions comprising:
projecting the image in response to an inputted image signal;
detecting an inclined angle of the projector;
calculating a rotational adjustment amount for the projected image based on the detected inclined angle;
rotationally deforming the projected image in accordance with the calculated rotational adjustment amount; and
detecting vibrations generated when a setting position of the projector is changed;
wherein, when power is supplied to the projector and vibrations are detected, the rotational adjustment amount is calculated and the projected image is rotationally deformed.
