Abstract:
1. An image data processing method, comprising: inputting a plurality of original pixel values of an image; determining an interpolation position of a target pixel in the image; determining whether the interpolation position of the target pixel is in a central region or a marginal region of an object and generating a determination result with respect to the target pixel; and selecting a pixel value interpolation mode according to the determination result to perform a pixel value interpolation, wherein the step of determining whether the interpolation position of the target pixel is in the central region or the marginal region of the object comprises: obtaining a first number of the original pixel values in a first direction and a second number of the original pixel values in a second direction with the interpolation position as a center and using the obtained original pixel values as a plurality of analysis samples; calculating a first uniformity of the first number of original pixel values, and calculating a second uniformity of the second number of original pixel values; calculating an absolute difference between the first uniformity and the second uniformity; and determining the interpolation position of the target pixel is in the central region of the object when the absolute difference is smaller than a first threshold and at least one of the first uniformity and the second uniformity is greater than a second threshold, and otherwise, determining the interpolation position of the target pixel is in the marginal region of the object.
