A digital camera is a camera that encodes digital images and videos digitally and stores them for later reproduction. Most cameras sold today are digital, and digital cameras are incorporated into many devices for example mobile phones amd vehicles.
Digital and film cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving video with sound. Some digital cameras can crop and stitch pictures and performs other elementary image editing.
Limitations
How you use a digital
camera to manipulate a digital graphic? – A
digital camera is plugged into the computer using a USB adapter and from there
any pictures that have been taken using the camera and are saved on the device
can be uploaded to the computer and saved in a folder and from there you are
able to make changes to any pictures e.g. Changing the colour, shape and fixing
red eye etc.
Mouse
A computer mouse is an input device that is used both with laptops and computers. Moving a mouse along a table or a mouse mat can move the on-screen marker to different items on the screen. Items can be moved or selected by clicking the mouse buttons.
It is called a computer mouse
because of the wire that connects the mouse to the computer. Today, many
computer mice use wireless technology and have no wire.The mouse is commonly known to take a big part in the manipulating of digital graphic as it gives you the ability to edit and change the graphic for example cropping the picture by moving the mouse to the amount of picture that you want.
How a mouse is used to manipulate a digital graphic? – The mouse can change any aspect of any image simply by the user clicking on either the right or left button and clicking on a colour or an icon in which to change an image’s size or shape etc.
