Abstract: The present invention provides a resonant switched capacitor voltage converter (RSCC), which is coupled to and operates synchronously with another RSCC. The RSCC includes: plural switches, a resonant inductor, a resonant capacitor, and a control circuit. The control circuit controls the switches, so that the resonant capacitor and the resonant inductor are connected in series to each other, to perform resonant operation in a switching period, thus converting an input voltage to an output voltage. The control circuit generates a zero current signal and a first synchronization signal when a resonant inductor current flowing through the resonant inductor is zero. The control circuit turns off at least one corresponding switch according to the zero current signal. The control circuit turns on at least one corresponding switch according to the zero-current signal and a second synchronization signal, so that the RSCC operates in synchronization with at least another RSCC.

Abstract: An image device and an image processing integrated circuit (IC) of the image device are provided. The image device includes a camera module, a display panel, a central processing IC, and an image processing IC. Based on a control of the central processing IC, the image processing IC decides whether to pre-process an output of the camera module and provide a pre-processed result to the central processing IC, or provide the output of the camera module directly to the central processing IC. Based on the control of the central processing IC, the image processing IC decides whether to post-process an output of the central processing IC and provide a post-processed result to the display panel, or provide the output of the central processing IC directly to the display panel.

Abstract: A multimedia apparatus has a function of detecting video signal connection. The multimedia apparatus includes plural video output terminals. The user may selectively connect one of the video output terminals with a TV set. The analog video signal outputted from the video output terminal is detected by a detector. In a case that the connection between the first video output terminal and the TV set is interrupted but the second video output terminal is connected with the TV set, the detector issues control signal. According to the control signal, a first digital-to-analog converter is disabled to stop outputting a first analog video signal through the first video output terminal, and a second digital-to-analog converter is enabled to output a second analog video signal through the second video output terminal.

Abstract: The mechanism of a sub-picture processing method for displaying multiple subtitles in a video/audio playing apparatus is provided. The purpose for displaying multiple subtitles in different languages simultaneously can be achieved under a user's control. Due to the unique control procedures and the concept of time division multiplexing, the present invention only employs a single sub-picture decoding unit and a single image mixer to display multiple subtitles in different languages at any preferred positions of the main picture.

Abstract: A data communication circuit of a SDRAM for data communication comprises a plurality of data lines coupled to a plurality of data pins. The number of the data lines, according to an embodiment of the present invention, is less than the number of the data pins. When the data communication circuit receives/outputs data, one of the LDQM pin and the UDQM pin are enabled to receive/output a first part of the data. The other LDQM pin and the UDQM pin are enabled. Accordingly, the data communication circuit of the SDRAM, according to an embodiment of the present invention, is capable of transmitting more data using a bus with a narrow width.
