Abstract: Image processing method and device are disclosed. The image processing method is inclusive of a step of obtaining a target image; a step of performing motion estimation on the target image so as to attain motion paths; a step of determining, on the basis of the motion paths, whether there exists a fluctuation meeting a predetermined requirement in the target image; and a step of taking, if there exists a fluctuation meeting the predetermined requirement in the target image, the target image as a reference image. The reference image is utilized to carry out inter frame motion estimation with respect to the respective images acquired.

Abstract: Apparatus and associated methods relate to configuring a circuit to sense current in a low-cost non-precision resistance, calibrating the circuit to correct inaccuracy measured in the sensed current, and measuring with the corrected circuit the precise current sensed in the low-cost non-precision resistance. In an illustrative example, the low-cost non-precision resistance may be a metal trace on a printed circuit board. The circuit may be calibrated, for example, over a range of currents or temperatures, permitting automatic adjustment to a wide range of non-precision resistance parameter values and environmental conditions. In some examples, correcting coefficients may be adapted to compensate for resistance non-linearities, which may include skin effect or self-heating. Some embodiments may verify the calibrated correction over a range of current and temperature.

Abstract: The present invention discloses a crystal coating optical low pass filter, which includes a UV-IR cut-off film, a crystal plate, an ink layer, and an AR film. The UV-IR cut-off film can be replaced with an IR film. By coating the crystal plate with ink having infrared absorbing effect to form an ink layer, the present invention possesses both the birefringence characteristic of the crystal and the effect similar to infrared absorbing glass. Compared with the traditional OLPF using infrared absorbing glass, the thickness of the product is reduced and the situation that the infrared absorb glass is fragile and has a poor resistance to drop is significantly improved. The present invention can be used in smartphones, digital cameras, in-vehicle cameras, security cameras and has a large space of marketing.

Abstract: The present invention discloses a coated narrow-band filter having an absorbent material. Two sides of the substrate are respectively an A-side and a B-side, a cut-off layer is coated or screen printed on the A-side, wherein lights having a wavelength within a first band are allowed to pass through the cut-off layer. The substrate is an absorbent layer, or an absorbent layer is provided on the B-side of the substrate. The absorbent layer is made of an absorbent material, lights having a wavelength within a second band are allowed to pass through the absorbent layer. The first band partially overlaps with the second band.

Abstract: A Li-ion power cell includes at least two winding cores produced by a winding process. Each of the winding cores has an anode tab and a cathode tab. The anode tabs and the cathode tabs of the respective winding cores are connected in parallel, respectively. The winding core is of cylindrical or diamond shape. The Li-ion power cell further includes a housing, an anode pole and a cathode pole which are disposed on the housing. The anode tabs of the respective winding cores are connected in parallel and then electrically connected to the anode pole, and the cathode tabs of the respective winding cores are connected in parallel and then electrically connected to the cathode pole.

Abstract: An adaptive intra-field algorithm to de-interlace video data uses two line memories to implement a median filter that can use multiple data points on adjacent lines of display. In a median-mode, the filter outputs the median of the input data to create the value for a location on the intermediate line and can decrease image blurring. But if examination of the two adjacent pixels on two adjacent scan lines is small, as in the case of a vertical image line, the filter operates as a line average filter, to avoid creating image artifacts.
