摘要： A projector, a method for controlling the same, and a projection system which can improve the resolution more efficiently by pixel shifting are disclosed. The projector controls the degree of modulation in a plurality of optical modulation devices and generates a plurality of optical images. To the plurality of optical images, the projector applies first pixel shifting according to the period and second pixel shifting regardless of the period, and projects a resulting image. The first pixel shifting and the second pixel shifting are different from each other, either in the amount of pixel shifting or the direction of pixel shifting.

摘要： A control apparatus capable of setting a suitable correction parameter while reducing user's troublesome. The control apparatus including a database that holds correction parameters for correcting pickup images to reduce color difference between pickup images of image pickup apparatuses in association with combinations of standard image pickup apparatus information and image pickup conditions of image pickup apparatuses, a memory device that stores instructions, and a processor that executes the instructions to obtain first information showing a standard image pickup apparatus at a present time and second information showing a target image pickup apparatus that picks up an image as a correction target at the present time, obtain the image pickup conditions of the image pickup apparatuses, determine a setting correction parameter that is set to the target image pickup apparatus from the database based on the first information and the image pickup conditions apparatuses, and output the setting correction parameter.
