  • Patent number: 10176129
    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.

  • Patent number: 9530231
    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.

  • Publication number: 20160240575
    Abstract: The invention provides an optical device. The optical device includes an image capture unit, at least one light emitting device, and a light conductor. The light conductor defines a space above a substrate on which the image capture unit is disposed. The light conductor includes a central portion and a surrounding portion. The central portion is disposed above the space and has a first surface relatively far from the image capture unit and a second surface opposite to the first surface and relatively close to the image capture unit. The surrounding portion is connected to the central portion and surrounding the space. The surrounding portion includes a reflection surface connected to the first surface and tilted at an angle toward the image capture unit with respect to a plane of the first surface. The reflection surface is adapted to perform total reflection.

  • Patent number: 7667718
    Abstract: An image scaling circuit and a method for scaling an image into images with different ratios are provided. The image scaling circuit includes a line buffer memory apparatus, a line buffer control apparatus, a first and a second scaling circuit. The first scaling circuit is coupled to the line buffer memory apparatus, and performs a first image scaling interpolation operation on the data output by the line buffer memory apparatus. The second scaling circuit is coupled to the line buffer memory apparatus, and performs a second image scaling interpolation operation on the data output by the line buffer memory apparatus. The line buffer control apparatus is coupled to the line buffer memory apparatus, the first scaling circuit and the second scaling circuit, for controlling the line buffer memory apparatus to receive or output a scan line data according to the operation status of the first and second scaling circuits.
