Digital camera interpolation explained
By Jakob Jelling
Snapjunky.com
In a device such as a digital camera it is very important to
understand the very basic aspects of the device so as to
properly operate it and give it the due respect it deserves.
Such a topic is interpolation! These are accessories that help
the digital camera to perform the technologically advanced
features that it is capable of. In extreme explanatory and
simple terms it can be summed up as that interpolation refers to
software programs that can effectively enlarge image resolution
beyond the actual resolution by adding extra pixels using
complex mathematic calculations. Now, this is a feature that can
be absolutely useful in providing a good success to a user.
Looking into the technical aspects it can be stated that
interpolation is a technique where the spatial resolution of an
image is increased from its original size to a higher or larger
resolution. The spatial resolution of an image is simply its
horizontal x vertical pixel count. For example 1600 x 1200.
Again getting into further intricate details it can be stated
that there are two techniques of interpolation commonly used,
they are software and hardware. Again software interpolation can
be performed on a digital image using a one of a number of image
editing programs such as PhotoShop. This is often termed as
resizing and is done with a computer, performed on an image file
from a digital camera that already exists in a
file format such as JPG.
Hardware interpolation involves the resizing of an image, but it
differs from software interpolation in that the image is resized
algorithmically inside the camera during the image processing
sequence and before the image has been saved as a JPG image
file.
Also, it can be noted here that JPG is a compressed image
file format. Whenever a file is saved as a JPG file, image data
is lost in the compression process. Image data is thrown away in
exchange for file-size efficiency. Software interpolation is a
process performed after the JPG losses have been applied.
Hardware interpolation occurs inside the camera prior to JPG
compression and before JPG losses have been applied. The
resulting hardware interpolated images are of superior quality
to a comparable image interpolated in software.
These are basically the important points as discussed in the
above lines regarding the digital camera interpolation. The
explanation is worth for every user who can be a novice as well
as an expert and thus uncovers another great feature of a
digital camera, the process of interpolation.
