Abstract: 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.

Abstract: A control method for an optical fingerprint sensor and a touch controller are 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 applying an anti-loading driving (ALD) signal on 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 when the touch controller is in a touch operation period.

Abstract: A control method for a first device of an inter-integrated circuit (I2C) system including a microcontroller unit (MCU), includes receiving a first indication from the MCU of the I2C system, wherein the first indication configures the first device from a slave mode to a master mode; polling the first device itself for status information of the first device when the first device is in the master mode; determining whether the status information of the first device matches a target status after polling; and determining to perform a parameter adjustment on a second device of the I2C system when determining that the status information of the first device matches the target status.
