| 20090153732 | METHOD AND APPARATUS FOR ADAPTIVE SELECTION OF YC SEPARATION - A method for adaptive selection of YC separation is provided. While a video decoder is re-sampling, a frequency of a re-sampling signal and a pixel rate of an output signal have a fixed relation, which is used to determine if a sampling frequency of the signal is deviated. And, accordingly, an appropriate Y/C separation is selected and then performed to obtain a better image quality. | 06-18-2009 |

| 20150138439 | REAL-TIME FALSE COLOR REDUCTION SYSTEM AND METHOD FOR COLOR INTERPOLATION - A false color reduction system and method for color interpolation is disclosed in the present invention. The false color reduction system includes a red/blue color interpolation signal reference level estimator, a red/blue color interpolation signal noise analyzer and a red/blue color interpolation signal noise regulator. The red/blue color interpolation signal reference level estimator receives a RGB image array and a red/blue color interpolation signal of the RGB image array, and calculates a difference value between a green target pixel or a green interpolation pixel corresponding to a red/blue target pixel of the RGB image array and an average value of a plurality of green pixels nearby the green target pixel or the green interpolation pixel to generate a green difference signal. The red/blue color interpolation signal reference level estimator further calculates an average signal of the red/blue color interpolation signal and a plurality of the same color pixels around the red/blue color interpolation signal, and generates a red/blue reference level according to the green difference signal and the average signal. The red/blue color interpolation signal noise analyzer is coupled to the red/blue color interpolation signal reference level estimator and receives the red/blue reference level. The red/blue color interpolation signal noise analyzer determines if a value of the red/blue color interpolation signal is larger than a sum of the red/blue reference level and a correlation value, and determines the value of the red/blue color interpolation signal is smaller than a difference between the red/blue reference level and a correlation value so as to generate a analysis result. The red/blue color interpolation signal noise regulator is coupled to the red/blue color interpolation signal noise analyzer and receives the analysis result to correct the red/blue color interpolation signal. | 05-21-2015 |

| 20090073312 | METHOD FOR VIDEO CONVERSION OF VIDEO STREAM AND APPARATUS THEREOF - A method for video conversion of a video stream includes: interpolating a first interpolated frame according a first frame and a second frame of the video stream; and interpolating a second interpolated frame according to the first frame and the first interpolated frame. In addition, the method further includes interpolating a third interpolated frame according to the second frame and the first interpolated frame. | 03-19-2009 |
| 20090086093 | SINGLE-PASS MOTION ADAPTIVE DEINTERLACER AND METHOD THEREFORE - A frame construction engine constructs a first frame of deinterlaced video and a second frame of deinterlaced video based on a first field of interlaced video and based on a second field of interlaced video, independent of any other fields of interlaced video. The frame construction engine constructs the first frame of deinterlaced video by assigning pixel values from the first field of interlaced video to corresponding pixel locations in the first frame. The frame construction engine constructs the second frame of deinterlaced video by assigning pixel values from the second field of interlaced video to corresponding pixel locations in the second frame. Missing pixel locations in each of the frames are selected from a corresponding field of spatially interpolated pixel values or from an opposite field of deinterlaced video. | 04-02-2009 |
| 20090102967 | Image Processing - The present invention relates to methods and apparatus for interpolation of images, and in a particular example to de-interlacing of video signals using spatial interpolation. The present invention discloses a method for measuring the slope of a picture portion in which picture gradients are calculated from said selected pixel values and the slope measurement being derived from said gradient values. The invention also discloses a method of spatial interpolation of an array of pixel values, in which interpolated values are dependent upon the measurement of the slope associated with said array. Non-integer slopes can easily be accommodated with the method of the invention. | 04-23-2009 |
| 20090147132 | IMAGE INTERPOLATION APPARATUS - A first feature value calculator calculates a feature value of an entire screen, and a second feature value calculator calculates a feature value of only an image area designated by designation data stored in a designation data storage. An interpolation determiner outputs a control signal indicative of interpolation-ON if the two feature values are matched or outputs a control signal indicative of interpolation-OFF if not. A center area interpolator uses a motion vector output from a motion estimator to generate an interpolated image within an image area. Side area interpolator performs process of interpolating a side area of the screen on interpolation-ON and stops the process of interpolating a side area of the screen on interpolation-OFF. Therefore, on interpolation-ON, an interpolated frame interpolating the entire screen is output. On interpolation-OFF, an interpolated frame interpolating only the designated image area is output. | 06-11-2009 |
| 20090174814 | Image Processing Circuit and Method Thereof - An image processing circuit generating a frame according to a plurality of fields including at least first, second and third fields, comprises a memory unit and a de-interlacing unit. The memory unit stores the first and second fields. The de-interlacing unit receives the third field, and reads the first and second fields from the memory to generate a de-interlaced frame accordingly. | 07-09-2009 |
| 20100177241 | APPARATUS AND METHOD FOR MOTION ADAPTIVE DE-INTERLACING WITH CHROMA UP-SAMPLING ERROR REMOVER - An apparatus and a method for motion adaptive de-interlacing with chroma up-sampling error remover are provided. Wherein, a motion detector determines moving pixels and static pixels in a target scan line. A first CUE remover and a second CUE remover remove the CUE of the target scan line in the previous field and the CUE of the adjacent scan lines in the current field, respectively. A de-interlace unit de-interlaces the adjacent scan lines to obtain a de-interlaced second scan line. A selector selects output data of the first CUE remover or the de-interlace unit as data of the target scan line according to a result of motion detection of the motion detector. A merging unit merges the adjacent scan line output by the second CUE remover and the target scan line output by the selector to output two scan lines of an output field. | 07-15-2010 |
