Abstract: A printer apparatus comprises a head having k (number) printing elements for printing an image data. A printing element selecting section selects a printing element driven at the time of printing among the k printing elements of the head. An image correcting section is a section for correcting the image data previous to the printing of the image data using the head, and comprises a correction data memorizing section for memorizing a correction data for a certain single tone among n (number) tones that the image data has for each of the printing elements, a tone detecting section for detecting the tone of the image data corresponding to each of the selected printing elements of the head, and a correction data generating section for generating a correction data for each of the selected printing elements, corresponding to the tone detected by the tone detecting section, by using the correction data memorized in the correction data memorizing section.

Abstract: 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.
