2 Types of hardware used for manipulating digital images

Digital Camera


A digital camera is a hand held device that is used for capturing images and uploading them to a desktop computer or a laptop via a USB cord.  It can also be used to capture videos.  With a digital camera you are able to view the images that have been captured with a built in screen on the back of the camera itself, this allows you to be able to view the images taken and if you don't like them or if you feel they need to be taken again you are able to delete the images from you're camera giving you extra room to take more pictures.  The majority of cameras now a days have been modified to be able to record videos of anything including sound as well as capture still digital pictures. 






Digital cameras tend to run out of battery life quicker than any mobile device, so you always have to carry around extra batteries, but this is different if the camera has a built in battery pack and needs electricity to charge because if you are out and about and the battery runs low there is no were to be able to charge it.

Another limitation for the digital camera is that the majority of them only support a certain brand or model of memory cards and that generally tends to be the SanDisk SD card or it could be other models as long as the model is SD or micro SD.  This can sometimes be a problem because the memory cards used in digital cameras tend to be slightly overpriced.





iPhone (model 3-6)


The iPhone is a hand held mobile phone device that is used to make phone calls, text message, upload music files to a computer and also take digital pictures and upload them through a USB cord.  The first iPhone was only able to take still digital pictures as they were, they were not able to zoom in or out of a picture to capture the right size.  Over the years there have been newer and newer versions of the iPhone being released, the newer versions however are not different from the others apart from the camera the camera has been modified were it is able to zoom in and out of pictures and is also now able to record videos and save them onto the phone as well as still being able to upload onto a computer.


 





Difference between a Digital Camera and a iPhone

The difference between a Digital Camera and any of the iPhone models is that the digital camera is able to capture images and edit them on the camera i.e. fix red eye and they are also able to focus themselves in to capture a picture without it being fuzzy whereas the iPhone is unable to do this, it is only able to zoom in and out of pictures and is not able to focus in on an images.  When taking an images with the iPhone you have to have a steady hand if you take a picture with the iPhone and it turns out fuzzy you have to delete that image and do it again whereas the digital camera you don't.  This can mean that the software built into the iPhone is limited compared to a hand held Digital Camera.

The iphone is set up in a way that any user is unable to set there own ringtone as what they want it to be as whereas most phones do.  It started off that the apple iphone was unable to record videos on it and also was unable to zoom in and out with the camera and this tended to be a big problem for people because when they took a picture it showed the outside surrounding as well and this was wither or not you wanted it to do it.  Also when you moved in with the phone to sort of zoom in with the camera itself zooming in it tended to make the picture slightly blurring at times.
