Abstract:
1. A projection system comprising: an information processing apparatus that carries out image processing on an image of an image source in which color tone of each pixel is represented with a predetermined amount of information, the image source including a plurality of image data, including latest image data and preceding image data; and a projector that projects an image based on an image data signal outputted from the information processing apparatus; and a signal transmission unit that carries signals between the information processing apparatus and the projector, wherein: the information processing apparatus includes: the projector includes a current-image frame generation unit that generates a new current-image frame based on the modified-image data from the information processing apparatus, the modified-part detection unit detects the modified part with an accuracy of not more than the amount of information indicating the color tone of each pixel of the image source, the modified-part detection unit compares image data with each other that are color-tone-corrected by the color-tone correction unit, and detects the modified part with an accuracy of not more than the amount of information indicating the color tone after color-tone correction.
