The invention discloses a screen size adjustment method for LCD projectors, comprising a design of UI interface based on LCD display, a setting of zoom ratio threshold and a realization of UI zoom ratio function. The LCD projector screen size adjustment needs to be designed based on application scenarios and LCD display resolution (W.sub.Panel×H.sub.Panel) of the projector. A reasonable zoom ratio threshold is set based on the application scenario and product definition. After the zoom ratio threshold is determined, the system interface needs to be designed. When designing the system interface, the system interface resolution (W.sub.UI×H.sub.UI) should be determined according to the product of the screen resolution and the minimum value of the zoom ratio (Z.sub.min), and the number of width and height pixels used in the final design of the system interface should not be higher than the value calculated above.

A control method for a projector includes, executing a first mode to generate a projection image projected onto a display surface by modifying a shape of an input image, accepting a change operation to the input image for changing a size of a display image displayed as the projection image is projected on the display surface or a position of the display image on the display surface, during the execution of the first mode, and shifting from the first mode to a second mode to control a change to the input image based on the change operation, when the change operation is accepted.

An apparatus and method for optically remapping projected pixels to maximize the utilization and to optimize the distribution of remapped projection pixels to achieve optimal visual performance (generally uniform resolution and luminance). A device interposed between a projector and an imaging surface for optically remapping projected pixel locations with minimal aberration. When this device is interposed between a projector and an imaging surface, it changes the terminal location of each focused pixel such that it maximally coincides with the imaging surface, which is often a surface of complex curvature and very different from the native focal surface of the projector. One implementation of the technology includes a device that uses multiple optical surfaces.

The scale calculation section calculates a scale correction value for a display mode of the locus of the input position in reference to distance information regarding the distance between the display apparatus and the input position. The input display generation section generates an input image depicting the locus of the input position through the use of the transformation matrix and the scale correction value.
