Patent number: 8810677Abstract: An image processing apparatus and a processing method thereof are provided. The image processing apparatus includes an image capturing module, an image separation module, an image stabilization module, a temporal noise reduction module, and a spatial noise reduction module. The image capturing module captures a plurality of Bayer pattern images. The image separation module decreases the Bayer pattern images in size and transforms them into a plurality of YCbCr format images. The image stabilization module receives Y channel images of the YCbCr format images and the Bayer pattern images to perform motion estimation, to produce a plurality of global motion vectors (GMVs). The temporal noise reduction module performs temporal blending process on the Bayer pattern images according to the GMVs, to produce first noise reduction images. The spatial noise reduction module performs 2-dimensional spatial noise reduction on the first noise reduction images to produce second noise reduction images.Type: GrantFiled: December 23, 2011Date of Patent: August 19, 2014Assignee: Altek CorporationInventors: Chi-Tung Hsu, Shih-Fang Chuang

Patent number: 7292625Abstract: A downstream power calibration method comprises the following procedures. First, select base sampling frequencies and sampling power levels, thereby generating base sampling signals. Next, input base sampling signals into a modem such that obtaining each sum of the feedback signals responding to the tuner and the IF amplifier of the modem by the modem chip corresponding each said base sampling signal, thereby setting up a sampling data table. Third, repeat the procedure mention above for a plurality of modems to get a plurality of sampling data tables respectively, and then obtain a mean data table. Fourth, select spot frequencies and spot power levels from the base sampling frequencies and the base sampling power levels to generate spot sampling signals. Thereafter, input the spot sampling signals into a cable modem and set up a skeleton data table.Type: GrantFiled: January 17, 2002Date of Patent: November 6, 2007Assignee: Askey Computer Corp.Inventor: Chi-Tung Hsu
