1. An image processing method, comprising:
adjusting a size of an input kernel;
setting an offset window for an offset pattern of a kernel offset and an offset parameter for an application intensity of the kernel offset;
determining an output kernel by applying the kernel offset to the input kernel based on the offset window and the offset parameter; and
adjusting contrast of a degraded image using the output kernel,
wherein the setting of the offset window and the offset parameter comprises setting a size of the offset window and the offset parameter based on the adjusted size of the input kernel.
