Abstract:
1. An automatic image adjusting method for use in a projector, the projector co-operating with a server, the automatic image adjusting method comprising the following steps: (a) enabling the projector to receive an initial image signal from the server, and to project an initial image at a first orientation according to the initial image signal; (b) enabling the projector to sense an angle difference value generated while the first orientation of the projector is changed to a second orientation; (c) enabling the projector to generate an angle signal according to the angle difference value, and to transmit the angle signal to the server so that the server generates a rotated image signal according to the angle signal and the initial image signal; and (d) enabling the projector to receive the rotated image signal from the server, and to project a rotated image at the second orientation according to both of the rotated image signal and the initial image signal, wherein the rotated image and the initial image have the same image aspect, and the rotated image signal includes difference content between an image signal after rotation and the initial image signal.
