a Digital Camera
With most phone digital cameras, taking pictures
is just point the camera, look at the screen and push the shutter button. The phone's LCD
screens let you see the image before you shoot and allow you
to delete pictures you don’t want, saving you time,
effort, and camera memory. Digital camera memory limits vary and may be
supplemented with memory cards or specialty storage disks.
All cameras have some kind of delete
feature, which may allow you to delete selected images, or
may require that the entire memory must be deleted. Some
cameras allow images from the computer screen to saved as
digital photos for use in print or video applications.
Phone based digital cameras allow you to actually
view the pictures taken with built in LCD screens, without
having to connect to an outside viewing medium. Digital
cameras then can be connected and the picture files downloaded to a computer. The phone usually connects the camera to the
computer using a USB ports, although you can also send images using wifi or other wireless options. , and some connect directly into a
computer slot. New cameras store directly on floppy disks or
cards that use floppy disk adapters.
Certain mobile device digital cameras have video output
that allow the camera to send out an NTSC or PAL video signal
directly through a standard RGB cable to a television,
projector or VCR.
digital cameras save pictures in a digital file format, which
may be camera specific or standardized, such as PNG or
JPEG. The format that pictures are saved in will determine
the amount of disk space needed to save a picture. Picture

Almost any printer can
print images, but for the best quality, use a high resolution
ink jet or laser printer. Currently there are printers and/or
printing accessories specifically designed for printing
pictures. To print high quality "photo style"
images you should use a printer that can take a photo quality
ink cartridge and print onto glossy or semi-gloss paper.
Most mobile device cameras include their own cables
to connect to either a PC or Mac computer, and some include the cables for direct video output. It is possible
that you will need to purchase cables, but it is also
possible to build your own, with a little work.
Most mobile device cameras include some kind of basic image handling
software. Depending on the software, capabilities
may be as simple as view and save or may have numerous
picture editing capabilities. Pictures can always be used
with the popular graphics and imaging software programs, such
as PhotoShop, Picasa or GIMP.
High resolution images are often large files and saving
them can take up a lot of your disk space. It is possible to
save the images in compressed formats like JPEG or GIF, and
save disk room. If you plan to save lots of images, an
external drive is recommended.
