Claim 7:
8. A scaling method of a real-time image, incorporated with a scaling device, and the scaling method comprising:
a) obtaining the real-time image through an image outputting device;
b) filtering out one or more lookup tables that the scaling device does not afford from a storage unit based on a current hardware resource of the scaling device, and deciding the lookup table and a lookup parameter by a determining unit of the scaling device in accordance with a content of the real-time image and a scaling ratio with respect to the image outputting device, wherein the scaling ratio is generated whenever an input or an output of the scaling device is rotated, the scaling ratio is manually set by a user, or a size of an output image is adjusted manually by the user through a touch screen, wherein the storing unit is configured to store multiple of the lookup tables and multiple of the lookup parameters, each of the lookup tables respectively corresponds to one of multiple scaling algorithms, and each of the lookup parameters respectively records a relationship between each pixel point in the real-time image and a weighting value of each field in a corresponding one of the multiple lookup tables, wherein each of the lookup tables respectively corresponding to the one of the multiple scaling algorithms is established in accordance with multiple computation weighting values, each of the multiple computation weighting values is retrieved from multiple computation formulas used in each of the multiple scaling algorithms;
c) performing a scaling process on the real-time image by a computing unit of the scaling device in accordance with the lookup table and the lookup parameter decided in the step b) to generate a processed image; and
d) outputting the processed image by an outputting unit of the scaling device.
