A projection system is provided which includes: 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; 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 protector, where the information processing apparatus includes: a modified-part detection unit that 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 a modified-image data generation unit that generates modified-image data of the modified part by adding color-tone data to each pixel in the modified part detected by the modified-part detection unit, where 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, and where 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.
