The Camera captures photos and videos. Phones have varying qualities
of built-in cameras, often including features and functions. However, the
higher the camera's megapixel count, the higher-resolution and better quality
of the captured photo.
Megapixel - In digital imaging, a pixel is the smallest item of
information in an image. A megapixel is 1 million pixels, and expresses
the number of image sensor elements of a digital camera -- and hence the
captured image size. For example, a camera with an array of 2048 x 1536
sensor elements is commonly said to have "3.1-megapixels" (2048 x 1536 =
3,145,728 pixels).
Generally, cameras will include common functions and features to alter
or aid the photo taking. These include:
Flash - The Flash illuminates the scene in dim lighting. Most
cameras used a photo "light," however few high-quality camera phones have
integrated Xenon flashes for more intense lightening. Lower quality camera
phones use "Night Mode" to increase the brightness through post-production,
rather than illuminating the scene, often having more grainy photos.
Zoom - To get closer, users can zoom in. Most camera phones use
"digital zoom" where the image is merely enlarged, similar to "cropping."
The quality of the image suffers. Few cameras include "optical zoom," where
the lens actually focuses on distant scenes. In optical zoom, no quality
is lost.
Auto-Focus - Locks onto the image for sharp photos without manual
focusing.
Macro - Takes close-up photos where normal modes would not be
able to capture detail.
White Balance - Adjusts the overall mixture of colors in an image
used for color correction for more accurate photos.
Color Effects - Adjusts the overall mixture of colors in an image
used for a desired effect such as black and white, tinting, or saturation.
Self-Timer - Takes photos after a set time period when users need
to be in the shot.
Multi-Shot - Takes multiple photos with one press, useful in capturing
scenes with rapid movement, such as sports.
Geotagging - Using GPS coordinates the camera can automatically
"tag" photos with its geographical location so when users flip back through
photos, they will be able to retrace steps to that exact location.
Panorama - Stitches together continuous shots for one large panoramic
image, useful in scenic photography.
Landscape - The camera takes photos in a horizontal orientation
for a real camera feel.
Video Calling - Two-way live calling with video with other users
with Video Calling capable phones.
