A receiver circuit includes a first amplifier circuit, a second amplifier circuit, and a selector circuit. The first amplifier circuit is configured to receive a pair of receiving signals. The second amplifier circuit is configured to receive the pair of receiving signals. Based on a selection signal, the first amplifier circuit generates a pair of first amplifying signals according to the pair of receiving signals or the second amplifier circuit generates a pair of second amplifying signals according to the pair of receiving signals. The selector circuit is configured to output the pair of first amplifying signals or the pair of second amplifying signals according to the selection signal.

Receiver circuit and operation method

A signal receiver includes a current source providing a current having a current value, a pair of active input devices, and a pair of resistors. Each active input device includes a control node, a first conduction node, and a second conduction node. One of the control nodes receives an input signal. The first conduction nodes are connected to each other and receive the current. One of the second conduction nodes serves as an output node. The active input devices output an output signal to a core circuit according to the current and the input signal. Each resistor has a resistance value. A target voltage value is determined according to the resistance value and the current value, such that a voltage swing of the output signal is limited within the target voltage value, and an operating voltage of the core circuit is substantially equal to the target voltage value.

Signal receiver

A method for detecting left-eye/right-eye images is capable of effectively and accurately detecting a sequence or positions of left-eye/right-eye image frames of a stereo image signal. The method includes performing block matching on a target block corresponding to two consecutive image frames of an image signal to determine a motion vector; and performing left-eye/right-eye image determination on a current image frame from the two consecutive image frames according to the motion vector.

Image detecting apparatus and method thereof

A low-power display control method and associated display controller is provided. The low-power display control method detects a sensing signal to generate a sensing result. A control signal is generated according to the sensing result to control a power conversion controller to operate in a low-power power saving mode. In response to a wake-up event, the control signal is deasserted and an associated auxiliary circuit is also turned off, and then the display controller is woken up to restore to a normal operating mode.

Low-power display control method and associated display controller

Disclosed is an image correction method of correcting an image including a number of horizontal image scan lines each corresponding to a number of pieces of image data. The method includes the following steps: segmenting each of the horizontal image scan lines into a plurality of segments according to a plurality of nodes, each of the segments having an original segment length; looking up a table to generate at least one correction parameter according to a selection signal; generating a gain value according to a control signal; correcting the original segment length to generate an adjusted segment length according to the gain value and the correction parameter; and altering positions of the plurality of nodes to correct the image according to the adjusted segment length.
