摘要： In a system according to the invention, fine image data 2 created and output by a personal computer 1 is input to an image processing/dividing section 4. The image processing/dividing section 4 determines, on the basis of parameters stored in a projector arrangement storage 5, which portion of the fine image data 2 is output to which projector, thereby performing a predetermined processing. Digital signals from the image processing/dividing section 4 are input to a plurality of D/A converters 6, respectively, where the signals are converted to analog signals. Images in the form of the analog signals are projected onto a screen 8 from projectors 7a-7d. Thus, the image projected on the screen 8 is constituted of accurately positioned images, and hence is a very fine image.

摘要： An image processing apparatus has a distortion correction processing unit. The image processing apparatus has a distortion correcting range calculating unit that calculates an input image range necessary for distortion correction processing of the distortion correction processing unit. Thus, the corrected image (output image) obtained by the distortion correction processing can be outputted without overs and shorts for the image output range. The distortion is corrected by effectively using input (picked-up) image data, serving as the original data. Further, the distortion including the pincushion distortion, the barrel distortion, and the curvilinear distortion is effectively corrected.
