Abstract:
A method for detecting sub-pixel motion for an optical navigation device is disclosed. The method calculates the displacement of the sub-pixel motion according to brightness curve equations of captured images, which is represented by positional coordinates x and y. The detection method includes capturing a first image frame and a second image frame at different times, selecting plural pixels from the first image frame as calculation reference pixels, generating brightness curve equations of the reference pixels, calculating partial-derivatives of the reference pixel to generate a plurality of two-dimensional first-order equations, and calculating the sub-pixel motion according to the plurality of the two-dimensional first-order equations. The method can reduce the pixel noise by choosing reliable pixels as the reference pixels. The method also reduce the noise by classifying the reference pixels.

Methods for repairing patterned structure of electronic devices. A first substrate with a patterned structure thereon is provided, wherein the patterned structure includes at least one defect. The defect corresponds to a defect region while the patterned structure corresponds to a main region. A first surface treatment is performed on the defect region such that the surface characteristics on the defect region are different from those on the main region. The defect region is repaired by inkjet printing. A second surface treatment is performed on the defect region such that the surface characteristics on the defect region are the same as those on the main region.
Abstract:
A white balance method is disclosed for image processing. Characteristic information of a portion of pixels in a first frame is detected. First pixels are selected when the characteristic information of the first pixels in the first frame meets an optical requirement. An average hue of the selected first pixels is obtained. A hue range the average hue belongs to is determined. Characteristic information of a portion of the pixels in a second frame is detected. Second pixels are selected when the characteristic information of the second pixels in the second frame meets the optical requirement and a pixel hue of the second pixels is within the hue range. A first average red-channel value, a first average green-channel value, and a first average blue-channel value of the selected second pixels are obtained for acquiring a gain of each color component of an image. The gain of each color component of the image is adjusted according to the hue range.

A coding method and system with an adaptive bitplane coding mode is provided to code multiple bitplanes of a frame consisting of multiple macroblocks. Each bitplane consists of macroblock modes used by the macroblocks of the frame. The method includes the steps of: (A) initializing a bitplane coding mode of the frame as a compress mode; (B) coding the frame and the bitplanes to thereby obtain coded bitplanes, and calculating the bit number of coded bitplanes; (C) calculating the bit number of uncoded bitplanes; (D) executing step (A) when the bit number of coded bitplanes is smaller than the bit number of uncoded bitplanes; (E) initializing the bitplane coding mode of the frame as a raw mode when the bit number of coded bitplanes is not smaller than the bit number of uncoded bitplanes.
Abstract:
A bicycle tube connector is a hollow body formed by the coupling of a left shell and a right shell. The tube connector further comprises a transverse rotational shaft connected with two branches of a chain stay, a down tube hole for retaining an obliquely downward down tube. When the bicycle tubes are connected within the tube connector, the left and the right shells are soldered together along the engaged border therebetween. Therefore, the various tubes of the bicycle are more firmly secured and the outlook of the bicycle frame is slick.
