摘要： A display stand device is adapted for a display and includes a base, a first rotation member, a telescopic assembly, a track, and a motion assembly. The first rotation member is rotatably disposed on the base along a first axial direction. The telescopic assembly is telescopically disposed on the first rotation member along a second axial direction. The second axial direction is perpendicular to the first axial direction. The track is fixably disposed on the telescopic assembly along the first axial direction. The motion assembly is movably disposed on the track along the first axial direction and is adapted to be attached to the back of the display, so that the display linearly moves and rotates along the first axial direction relative to the base and rotates along a third axial direction. The third axial direction is perpendicular to the first axial direction and the second axial direction.

摘要： A wireless communication device and a moving method thereof are provided. The moving method is adapted for the wireless communication device moving in a zone. While moving in the zone, a wireless signal status of a signal source device is measured. The zone is divided into multiple sub-blocks, and a spatial weight parameter corresponding to each of the sub-blocks is determined according to the wireless signal state of the signal source device. In response to a user equipment being connected to the wireless communication device, a preferred sub-block is selected from the sub-blocks according to user context information of the user equipment and the spatial weight parameter corresponding to each of the sub-blocks. The wireless communication device moves into the preferred sub-block to perform wireless communication with the signal source device and the user equipment within the preferred sub-block.

摘要： A transmitter device adapted to be coupled to an image providing device and a receiver device includes first and second conversion units, a wireless module, and a processing unit. The first conversion unit and the second conversion unit are configured to be coupled to the image providing device through an HDMI transmission cable and a Type-C transmission cable, respectively, so as to respectively receive a first video and audio stream and a second video and audio stream provided by the image providing device. The wireless module is connected to the receiver device through wireless communication. The processing unit preferentially selects the first conversion unit to receive a first video and audio signal output by converting the first video and audio stream by the first conversion unit and transmits the first video and audio signal to the receiver device through the wireless module.

摘要： A conference system with low standby power consumption includes a transmitter, an image data source, a receiver, and a display device. The transmitter includes a battery for providing power, at least one link port for accessing data, and a processor coupled to the battery and the at least one link port. The image data source is used for transmitting the image data to the transmitter. The receiver is linked to the transmitter for receiving the image data. The display device is linked to the receiver for displaying the image data. When the transmitter and the image data source are electrically coupled, the processor ceases to use the battery of the transmitter and controls the image data source for providing power to the transmitter. When the transmitter and the image data source are separated, the processor uses the battery of the transmitter for driving firmware of the transmitter.

摘要： A cursor controlling method includes: A starting position on which a touch signal triggered by an object on the touch panel is detected, and a starting coordinate of the starting position is calculated; a cursor is display at a first coordinate on a display screen corresponding to the starting coordinate. A first vector of the object moving from the starting position to a first steering position on the touch panel is detected. The cursor is moved along a first moving vector corresponding to the first vector, with a first speed on the display screen, until the object is stopped on a first steering position of the touch panel, to make the cursor ended up at a first virtual position having a first virtual coordinate. The cursor is shifted from the first virtual coordinate to a second coordinate on the display screen and corresponding to the first steering position.

摘要： A projection device, a projection system and a method for calibrating projected image are provided. The projection device and an external projection device the same image source and respectively project an image and another image corresponding to the image source. The same portion of the image source where the two images overlap each other forms an overlapping area. The projection device includes a lens, a light shielding member and a processor. The light shielding member is disposed on the lens. The processor controls the light shielding member to selectively shade a partial area of the lens according to the brightness of the image source, wherein the partial area corresponds to the overlapping area.

摘要： An image adjusting method including the following steps is provided. Firstly, the original image is divided into a plurality of image areas by a plurality of mutually intersecting virtual lines, wherein the image areas include a plurality of edge areas, each being defined by at least one original image edge of the original image and at least two of the virtual lines. Then, the coordinate of at least one intersection of at least one of the virtual lines and the original image edge are changed to obtain a deformed image edge. Subsequently, at least one original pixel located in one of the edge regions in the original image is repositioned according to the at least two of the virtual lines and the deformed image edge.
