... map is converted back to an image, the pixel goes to its position and colour in relation to the other pixels making up the image and the co-ordinates given to it. From the A-D converter, algorithms are then applied to the data converting it into a digital image. Sometimes, the size of the data generated by an image sensor can be very large. The larger the number of pixels making up the picture, the higher the resolution of the image and the larger the size of the data of the image. To deal with these large files, most digital cameras compress the data, as to make the size of the data of the image smaller. The way the data representing an image is electronically written is called an 'image file format'. There are many different image file formats. Several of them use compression techniques to reduce the storage space required ...
