Picture Resolution 

Picture resolution can be used when you are taking a picture with a camera and trying to convert it into your game. For example if you want to make a photo realism game you would have to have quite a high end camera too be able to take a picture suitable for that purpose.

• How many pixels are shown within our image from top to bottom
• File size of the image
• You find out the number of pixels by multiplying the width and height of the image. 

Image resolution (Quality)

Image resolution could be when you have drawn a picture with a pen or pencil and trying to put it onto your computer without trying to lose any of the quality of the original drawing. You would have to use a scanner and make sure you have quite a lot of dots per inch so that you have the best quality possible with the drawing.

This means the quality of an image

As the resolution increases the image will slowly become clearer

An example of image resolution would be the difference between a very low quality picture such as a 240p image and a 1080p image.

Pixel Values

Describes what the colour will appear as or how bright it is.

to show colour values you must seperate the red, green and blue parts for each individual pixel. 

one bit number showing the background or the foreground.

The most common pixel format used is the byte image where the number would be stored as an 8bit image giving it a huge range value from 0 - 255. Usually 0 is black and 255 is white. The numbers in between the two are what makes up the different shades of grey.
