摘要：
A projection system includes: an information processing apparatus that carries out image processing on an image of an image source; 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. The information processing apparatus compares latest image data with preceding image data, and detects, as a modified part, part of the latest image data that is modified from the preceding image data and generates modified-image data of the modified part by adding color-tone data to each pixel in the modified part. The projector generates a new current-image frame based on the modified-image data from the information processing apparatus. The modified part is detected with an accuracy of not more than the amount of information indicating the color tone of each pixel of the image source.
