A control method for an optical fingerprint sensor and a touch controller is provided, for canceling or reducing capacitive loading. The optical fingerprint sensor includes a plurality of pixels, and each of the pixels has a first control signal line and a second control signal line. Each of the pixels is further coupled to a first voltage source line, a second voltage source line and a sensing line. The control method includes the step of configuring at least one of the first control signal line, the second control signal line, the first voltage source line, the second voltage source line and the sensing line to be floating when the touch controller is in a touch operation period.

A method for generating masking image using general polygonal mask includes receiving a pixel of a raw image and a polygon vertices array corresponding to a polygonal mask, determining whether the pixel is inside the polygonal mask, labeling the pixel to be a masked pixel if the pixel is inside the polygonal mask, or labeling the pixel to be a visible pixel if the pixel is outside the polygonal mask, and outputting the masked pixel or the visible pixel to generate the masking image.

A real time clock integrated circuit (RTC IC) and an electronic apparatus thereof are provided. In the RTC IC, only a low-power oscillator is used for generating a standard clock for a real time counter, and the standard clock with a frequency drift of the low-power oscillator is compensated through table lookup. Accordingly, the power consumption, fabrication cost and design complexity of the RTC IC are reduced and the counting operation duration of the RTC IC is prolonged.
