Abstract:
1. A method for converting an image in interlaced format to progressive scan format, comprising: determining a target pixel of pixels of the image; calculating a first value based on pixel values of a first set of pixels, wherein the first set of pixels do not include pixels in a column of the target pixel, the first set of pixels including a first subset of pixels and a second subset of pixels in a row above the target pixel and a third subset of pixels and a fourth subset of pixels in a row below the target pixel, wherein the first and the third subset of pixels are situated in columns left of the target pixel and the second and the fourth subset of pixels are situated in columns right of the target pixel; determining a second value based on pixel values of a second set of pixels, wherein the second set of pixels are located in the column of the target pixel, and wherein the step of calculating the first value includes: determining a pixel value of the target pixel based on adding the first and second values.
