Abstract: A method for fingerprint recognition and a fingerprint recognition device are provided. The method includes the following steps. A touch position of a touch panel is obtained as a fingerprint position. A fingerprint recognition operation is performed according to the fingerprint position. Whether the fingerprint recognition operation is successful is determined. In response to determining that the fingerprint recognition operation is not successful, at least one first position of the touch panel as an updated fingerprint position is generated according to the touch position of the touch panel, and the fingerprint recognition operation is performed according to the updated fingerprint position.

Abstract: An LED controller is used with a video source and at least one LED unit, and includes a control signal generator and a driver. The control signal generator performs pulse width modulation based on a first clock signal, a second clock signal and a data signal, which is generated by the video source, to generate at least one control signal. The first and second clock signals are independent of a vertical synchronization signal that is generated by the video source. The driver generates, based on the at least one control signal, at least one drive signal that is related to light emission of the at least one LED unit.

Abstract: A video encoder, a video decoder and a video system are provided. The video encoder performs a video encoding operation on a first video frame stream to generate an encoded stream to the video decoder, wherein the encoded stream contains deblocking filtering information. The video decoder performs a video decoding operation on the encoded stream to generate a second video frame stream. The video decoder determines whether to forcibly perform a deblocking filtering operation on a current block of a current frame of the second video frame stream according to the deblocking filtering information.
