TV pixel and Brain

TV is a load of small images put together

British TV plays 25 images (frames) per second. You need this many to make the movement look smooth.

Pixels are the amount of dots in an image the more pixels the better the image

Resolution is how clear the image is. This depends on the amount of pixels

Still frame is each of the pictures to make a moving image

TV screen is made up of 100 tiny scan lines. This is transmitted to your television. The UK rule is 625 lines. Different countries use slightly different ‘standards’ or systems- with different numbers of lines per screen and different numbers of frames per second.
