Pixels storyboard
Text z Príbehu
- 2. Well, funny you say that, I can teach you a little bit about pixels and how they make colours on digital screens!
- 1. Wow, look at all the rainbow colours in the movie, I wonder how the computer makes them all.
-
- 3. Images on screens are made of tiny dots called pixels. The better quality the device produces depends on the amount of pixels in the screen, this is called the resolution.
- 4. The pixels must be very, very small, I can barely see them on the computer.
-
- 6. Oh, this is interesting. The pixels are made of three tiny lights each. The lights are red, green and blue.
- 5. But how does the computer know what colours to show on the screen?
-
- 7. The three lights can vary in value from 0 to 255. 0 being the darkest and 255 being the lightest. These are the components to create a colour on a single pixel.
- 8. The lights must be even smaller than the pixels!But how do three colours make all the colours of the rainbow?
-
- 9. Well, the computer uses something called binary to tell the computer what amount of each colour to produce for each pixel. The number in code telling the computer what amount of each colour to produce is call an RGB triplet. An RGB triplet contains 3 numbers, 1 for each of the 3 colours. This is how the 3 colours can produce different colours with a mix of each.
- 10. I never realised computers and pixels were so complicated and detailed.
-
- 13. You're very welcome!
- 11. It definitely is a lot of information for the computer to process, especially in videos and clips where each second of film includes 30 different, separate images!
- 12.Thankyou for teaching me about pixels and how they produce colours.
