Spacial Interpolation is the technology enlarging the small image to a large-size image with better visual quality.
|
|
|
Spacial Interpolation technology has the following merits:
- It enables the enlargement of QVGA size image to VGA size
- It minimizes the data size, for example, when enlarged to 200%, the data size decreases to 1/4.
- Spacial Interpolation with integral numbers, such as 2 x 2 or 3 x 3 can be applicable for video images due to the small CPU calculation complexity.
