Abstract

A projection display apparatus which display a projected image and may be free from connection with a computer. The projection display apparatus carries out processing with information stored in a portable memory and includes a memory controller that reads out the information stored in the portable memory; an image processing section that prepares display image data. The display image data represents an image to be displayed from the image data stored in the portable memory according to an instruction of a processing program that is read from the portable memory and represents a series of processing steps to be executed by the projection display apparatus. An electro-optic device then forms image light in response to the display image data, and an optical system projects the image light to display the image.
