Abstract:
1. A projection system comprising: an image processor processing image data; a projector modulating a light beam emitted from a light source device on the basis of the image data processed by the image processor; and an information transmitting unit connecting the image processor and the projector to each other so as to transmit and receive information therebetween, wherein the image processor includes: a predicting unit predicting a subsequent image in a presentation sequence that is temporarily subsequent to an image currently displayed by the projector, wherein the presentation sequence is a previously set sequence; a transmitting unit transmitting subsequent image data which corresponds to the subsequent image predicted by the predicting unit; an operation signal detecting unit detecting an operation signal, which indicates that the currently displayed image is updated into a predetermined image, after the transmitting unit transmitted the subsequent image data; an update image judging unit comparing the predetermined image with the predicted subsequent image other than the currently displayed image; an update information generating unit capable of generating update information indicating that the currently displayed image is updated into either one of the predicted subsequent image other than the currently displayed image and an image other than the predicted subsequent image on the basis of the comparison result of the update image judging unit; an update information transmitting unit transmitting the update information; and wherein the projector includes: a projector reception unit receiving the subsequent image data and the update information; a storage unit capable of storing a plurality of the subsequent image data; a display control unit displaying an image based on the image data; and an image update unit updating the currently displayed image into the predicted subsequent image on the basis of the subsequent image data when the update information received by the projector reception unit indicates that the currently displayed image is updated into the predicted subsequent image.
