摘要： Disclosed are a calibration method and a calibration circuit. The calibration method and the calibration circuit effectively calibrate the mismatches between the first signal path and the second signal path of a receiver by calibrating a plurality of tap coefficients of a finite impulse response filter configured in the second signal path and optimizing the tap coefficients. The calibration and optimization for the tap coefficients of the finite impulse response filter is according to differences between the electrical characteristics the analog-to-digital convertor and the LPF in the first signal path and differences between the analog-to-digital convertor and the LPF in the second signal path. These differences are obtained when the data reception has not yet started by the receiver (that is, when the receiver is working in a training mode).

A first image is obtained. A first line-taking position parameter is determined according to a ratio of a first target edge length to a second target edge length. At least one line of input pixels disposed in a first direction is retrieved from the first image according to the first line-taking position parameter. A first scaling process related to the first direction is performed according to at least one line of input pixels of the first image, such that a line of output pixels of a second image disposed in the first direction is generated. The projection device projects the second image onto a projection screen to display a rectangular projected image.

摘要： A voltage regulating device and a mode switching detecting circuit are provided. The mode switching detecting circuit is configured to reset a soft start circuit of the voltage regulating device. The mode switching detecting circuit includes a mode switching signal detector, a reset signal generator, and a reset status detector. The mode switching signal detector receives a mode switching signal and generates a setting signal according to a transition edge of the mode switching signal. The reset signal generator is coupled to the mode switching signal detector and generates a reset activating signal according to the setting signal. The reset activating signal drives the soft start circuit to perform a reset operation. The reset status detector compares an output voltage of the soft start circuit and a reference voltage to generate a clear signal. The reset signal generator clears the reset activating signal according to the clear signal.
