Abstract: A display method and a display device using the same are provided. The display method includes following steps. Firstly, an initial color temperature of a display is set. Then, the display displays a display image at an initial color temperature. Then, a time period at which the display image is continuously displayed at the initial color temperature is detected. Then, when the time period has reached a predetermined time, the display displays the display image at a first color temperature different from the initial color temperature.

Abstract: An input device, a mouse using the same and a method using the same are provided. The input device capable of avoiding error action of a switch includes a first g diode, a second diode and a switch. The second diode is electrically connected to the first diode. The switch is electrically connected to between the first diode and the second diode.

Abstract: A projector and a projecting method using the same are provided. The projector includes a first light source, a color wheel and a second light source. The first light source is configured to emit a first color light. The second light source is configured to emit a second color light. The first color light passing through a transparent region of the color wheel becomes a third color light. The second color light and the third color light are mixed as a first projecting light. The first color light reflected by a phosphor reflection region of the color wheel becomes a fourth color light. The fourth color light is guided toward a projecting direction to become a second projecting light. The first projecting light and the second projecting light do not overlap in timing.

Abstract: After capturing a barcode image, generate at least one sample line accordingly, acquire sample data of the at least one sample line, generate a first and a second reference lines, generate an upper bound and a lower bound according to the first and the second reference lines, generate a first curve by interpolating all sample points, generate a plurality of effective sample shapes of the first curve according to the upper bound and the lower bound, identify an internal point of each effective sample shape, generate a second curve by interpolating all internal points, and digitize the barcode image to binary data by comparing sample data with the second curve.

Abstract: A sliding module includes a first element, a second element, and a third element disposed between the first and second elements and rotated between a first reference position and a second reference position. When the third element is located at the first reference position, the second element is positioned at a first predetermined position. When the third element is positioned at the second reference position, the second element is positioned at a second predetermined position. When the second element is moved from the first predetermined position toward a first direction, the second element pushes the third element to move from the first reference position toward the second reference position. When the second element is moved from the second predetermined position toward a second direction, the second element pushes the third element to move from the second reference position toward the first reference position.
