Image Resolution - Designed for Digital Images!

Image resolution is the term that explains the detail an image holds. It is generally implemented to digital images and other types of images. Image resolution can be precise in several ways. Resolution unit can be meant for physical sizes, overall size of a picture and to angular subtenant. The term resolution is always used for a pixel in digital imaging. Megapixel can be calculated by multiplying pixel columns by pixel rows and dividing by one million. Other convectional method of describing pixels per length unit is such as: pixel per inch and pixel per square inch. None of these pixel resolutions are true resolution. However, they are serving as upper bound on image resolution. As we know digital camera includes unused or light shielded pixels around the edges. Unluckily, the count of pixel is not the real measurement of the resolution of digital camera. Digital images genuinely needed a red, green and a blue value for each pixel to be printed.

Term resolution is used often for the pixel count in the digital imaging, although Japanese, American, as well as international standards specify it must not be very much used, in a digital camera field. The image of the N pixels higher by the M pixels wide will have any of the resolution less N lines every picture height, and N TV lines. However, while pixel counts are been referred as the resolution, convention is describing pixel resolution with a set of 2 positive integer numbers, and where first number is a number of the pixel columns and second is a number of the pixel rows, for instance as 640by480. One more famous convention is cite resolution as a total number of the pixels in an image, generally given as the number of megapixels that are calculated just by multiplying the pixel columns by the pixel rows & dividing by a million.
