ABSTRACT:
A projection system includes an image processing apparatus, a projector having an optical modulation element and a projection optical apparatus, and a digital communication unit. The image processing apparatus performs a projector correction process to generate first correction processed image data and an original display correction process to generate a second correction processed image data and generates difference data for a difference between the first correction processed image data and the second correction processed image data, and transmits the difference data to the projector through the digital communication unit. The projector performs the projector correction process on the image data to generate the first correction processed image data and a correction process based on the difference data on the first correction processed image data to generate the second correction processed image data, and controls the optical modulation element based on the second correction processed image data.
