Abstract: A ceiling fan including a fan device and a remote control is provided. The fan device includes a motor and a control unit. The remote control includes a gesture sensing unit and a processing unit. The gesture sensing unit includes a sensing module that is configured to obtain a sense image of an object, and includes a storage medium that stores a plurality of data sets and different reference tracks that respectively correspond to the data sets. The processing unit is configured to: obtain a movement track of the object; obtain a corresponding one of the data sets when the movement track conforms with one of the reference tracks; and output a command that is related to said corresponding one of the data sets to the control unit. In response to receipt of the command, the control unit adjusts rotational speed of the motor according to the command.

Abstract: An image edge enhancement apparatus and a method thereof used for adjusting the brightness of a pixel are provided. The image edge enhancement apparatus comprises a first edge judgment circuit, a second edge judgment circuit and a process circuit. The first edge judgment circuit retrieves the edge data of the pixel in a first direction to output a first edge value. The second edge judgment circuit retrieves the edge data of the pixel in a second direction to output a second edge value. The process circuit determines an operation mode according to the brightness of a plurality of adjacent pixels around the pixel, the first edge value and the second edge value to output an adjusted brightness of the pixel according to operation mode. The adjusting method effectively avoids the noise in an image being amplified, and avoids the same edge being repetitively enhanced by different edge judgment circuits.

Abstract: A display controller capable of reducing cache memory and a frame adjusting method thereof are provided. The display controller comprises a memory controller, a first memory, a second memory and a frame control circuit. The memory controller is for reading part of the image data from a source layer to obtain a first image data, and reading part of the image data from the target layer to obtain a second image data. The first memory is for storing the first image data. The second memory is for storing the second image data. The frame control circuit is for processing the first image data to generate a first processed image data overlaid with the second image data to obtain a second processed image data. If the second processed image data needs further processing, then the display controller loads the second processed image data to an external memory.
