摘要： In an image calibration device 10, a calibration pattern is projected onto a screen 4 from each projector 3 under control of a personal computer or other calibration device 10a, pictures are taken by a digital camera or other image pick-up device 11, and the results are supplied to the calibration device 10a. The calibration device 10a uses the supplied picture data to calculate parameters in order to perform picture positioning, color adjustment, brightness adjustment and other adjustments and corrections, and based on the calculation results transforms the original picture data, generates and supplies signals indicating projection conditions to each of the projectors 3, and performs image calibration control of the pictures projected by each projector 3. Here at the time of taking pictures, by installing on the image pick-up device 11 a shielding member 12 formed into a tetragonal pyramid shape, the light-receiving part of the image pick-up device 11 and the screen are completely shielded from ambient external light. By this means, the measurement precision of the image pick-up device 11 is improved, and accurate and reliable image calibration is performed.

摘要： The present invention provides a multi-display device that has a plurality of projectors and constructs one image as a whole. Partial images projected on a screen from the projectors overlap to have the edges thereof superposed on edges of adjoining partial images in shared fields on the screen. A sheet interceptor intercepts part of light to be projected on a shared field so that the luminance level in the shared field will agree with the luminance levels in the other fields except the shared fields. An interceptor portion of the sheet interceptor, which intercepts light from the right-hand side of a range on the screen within which a partial image is projected, can be displaced horizontally relative to an interceptor portion thereof that intercepts light from the left-hand side thereof. Likewise, an interceptor portion of the sheet interceptor that intercepts light from the upper side of the projected range can be displaced vertically relative to an interceptor portion thereof that intercepts light from the lower side thereof.

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.
