Abstract
A projector includes a moving unit adapted to move positions of at least six correction points, which are included in a correcting image, a reception unit adapted to receive a designation on a value of a parameter representing linearity, a derivation unit adapted to derive a correspondence relationship of the coordinates between and input image and the correcting image using coordinates of the at least six correction points moved by the moving unit, and the parameter having the value designation of which is received by the reception unit, and a processing unit adapted to perform a correction process on the input image based on the correspondence relationship derived by the derivation unit.
Claims15
A projector comprising:
- a moving unit adapted to move positions of at least six correction points, which are included in a correcting image;
- a reception unit adapted to receive a designation on a value of a parameter representing linearity;
- a derivation unit adapted to derive a correspondence relationship of the coordinates between an input image and the correcting image using coordinates of the at least six correction points moved by the moving unit, and the parameter having the value designation of which is received by the reception unit;
- and
- a processing unit adapted to perform a correction process on the input image based on the correspondence relationship derived by the derivation unit.
An image correction method comprising:
- moving positions of at least six correction points, which are included in a correcting image;
- receiving a designation on a value of a parameter representing linearity;
- deriving a correspondence relationship of the coordinates between an input image and the correcting image using coordinates of the at least six correction points moved, and the parameter having the value designation of which is received;
- and
- performing a correction process on the input image based on the correspondence relationship derived.
A computer-readable recording medium having a program recorded,
- the program making the computer perform a process comprising:
- moving positions of at least six correction points, which are included in a correcting image;
- receiving a designation on a value of a parameter representing linearity;
- deriving a correspondence relationship of the coordinates between an input image and the correcting image using coordinates of the at least six correction points moved, and the parameter having the value designation of which is received;
- and
- performing a correction process on the input image based on the correspondence relationship derived.
