ABSTRACT:
A calligraphy/drawing camera image-captures a document and sends a resultant captured image to a personal computer (S101). The personal computer applies various image processes such as correction of various deformations including a trapezoidal deformation based on image information obtained from the captured image, a rotation process, a cut out process, etc. to the captured image (S102to S104). The personal computer sends the processed image to a projector (S105). The projector projects the processed image on a screen (S106). Since the captured image is corrected based on the image information obtained from the captured image, not only correction of a trapezoidal deformation but also various other corrections can be done on the captured image.
