The decision to purchase a Canon Digital camera can sometimes be overwhelming when it is difficult to understand terms which are technical in nature. However if you wish to make the right choice in your purchase, you will have to know the meaning of these terms. This guide is written to help explain the meaning of what a pixel is and how its usage is related too to digital imaging.
The word pixel actually stands for the term PICTURE ELEMENT. All digital pictures taken by the Canon Digital camera are composed of pixels. They are, in reality, tiny squares with different colors mosaic together like a giant jigsaw puzzle to form a digital image. Although at a glance, this is not evident until you enlarge the digital image significantly. Only then will you be able to see the little squares of different colors and hues. The colors and hue of each pixel is represented by 3 numbers, one number for the red, green and blue color channel. These numbers each, ranges from 0 to 255. Taken all together, there are 16 million possible color combinations that can be represented by these 3 numbers.
Beside from using pixel counts for the display of digital images, nowadays, Digital Camera manufacturers also uses pixel counts to grade the capabilities of their digital cameras. Canon has digital cameras which range from 5 to 10 million pixels. They are normally classified as megapixels cameras because one mega pixels is equivalent to one million pixels. When we say a camera can take 5 megapixels pictures, this mean the digital image which the camera takes have 5 million pixels in it. The numbers of pixel a digital camera has is not important when the image is used displayed on a monitor. However when you need to print these images, the pixels do matter as the higher the picture count, the sharper and crisper the prints will be.
When taking into account pixel counts, it is also important to differentiate between "Total Pixels" or "Effective Pixels". Total Pixels takes in consideration every pixel in an image. However, normally in the final image, the edge pixels are not used at all. Thus Effective Pixels refers to the numbers of pixels used after the edge pixels of the image are discarded.
If you use a Canon 5 megapixels camera, the quality of its 5" by 7" is of excellent quality. Printing larger pictures like 8" by 10" will result in lesser quality but is still of decent quality. Nevertheless, if you are printing 8" by 10" pictures as a norm, then it is better if you buy a 8 to 10 megapixels Canon Digital Camera. - 16039
