What is Interpolation?
| Interpolation |
|
A process that occurs automatically when an image's dimensions or resolution are changed which results in re-coloring the pixels. Interpolation may cause an image to look blurry when it's printed. You can choose an interpolation method in PhotoShop from slower, but better, to faster but lower quality. A method of increasing image resolution artificially. A digital camera relies on its internal hardware components to capture images. The hardware typically has a maximum image resolution for instance, 1,280 x 1,024 pixels-that it can achieve. That resolution is known as the camera's optical resolution. Some cameras, however, use built-in software coding to capture images with resolution than exceeds the camera's hardware limitations. That resolution is known as the camera's interpolated resolution. Interpolation creates new pixels from those that exist and inserts them in-between the existing pixels to increase the image's overall resolution. Though interpolation can improve picture quality, interpolated images tend to look fuzzy when enlarged. |
