An audio compensation method is applied to a playback device which includes a first distance detector, a second distance detector, an audio output module and an operation processor. The operation processor executes the audio compensation method to acquire a projection distance and a relative angle of the playback device relative to a projection screen via the first distance detector and the second distance detector, to acquire an installation parameter of the playback device, to search at least one audio output setting from an audio setting table in accordance with the projection distance and the relative angle and the installation parameter, and utilize the audio output setting to drive the audio output module.

A method for controlling projectors includes identifying a first projector and a second projector by using a database, acquiring a first control code of the first projector and a second control code of the second projector after the first projector and the second projector are identified, and generating at least one control signal to the first projector and the second projector for controlling operational actions of the first projector and the second projector according to the first control code and the second control code.

Method and control system for controlling projectors of different models by using control codes

An image adjusting method includes steps of displaying an image, wherein the image includes M*N original pixels and M and N are positive integers larger than 2; simplifying the M*N original pixels to be P*Q simplified pixels, wherein P is a positive integer smaller than M and larger than 1, and Q is a positive integer smaller than N and larger than 1; setting an initial pixel and a target pixel within the P*Q simplified pixels; finding a plurality of intermediate pixels between the initial pixel and the target pixel; and adjusting the initial pixel, the intermediate pixels and the target pixel pixel by pixel.

Image adjusting method

A projector display module and its power saving method are provided. The projector display module includes a signal source, an analog-to-digital converter, a display control unit, a ballast, and a light source. The display control unit retrieves signal from the signal source and outputs a control signal to the ballast to adjust the power of light source. The display control unit includes a comparison module and a control signal generation module. The power saving method includes the following steps: retrieving the first pixel data of a preset position of the first frame and the second pixel data of the preset position of the second frame from the signal source. The display control unit compares the first pixel data and the second data to produce a comparison result. According to the comparison result, the display control unit produces a control signal to adjust the power of light source.
