Binary Images: Pixels and Patterns

Learning Objectives Define a pixel as a tiny square of light on a screen. Explain that binary means using only two options, like 0 and 1, or on and off. Represent the color black with the number 1 and the color white with the number 0. Create a simple black and white picture on a grid using only 0s and 1s. Decode a grid of 0s and 1s to reveal a hidden picture. Describe how a computer uses a pattern of 0s and 1s to show a simple image. Have you ever wondered how a computer draws a smiley face? 🤔 It's like a secret code made of only two numbers! Today, we're going to become code detectives! We'll learn how computers use tiny dots called pixels and a special code called binary (just 0s and 1s) to create all the pictures we see on screens. It's the first st...

TermDefinitionExample PixelA single tiny dot or square of light on a screen. Millions of pixels work together to make a full picture.Look very close at your computer screen. You might see the tiny squares that make up a letter or picture. Each one is a pixel! BinaryA way of representing information using only two options. For us, we will use the numbers 0 and 1.A light switch is binary. It can only be 'on' or 'off'. Binary ImageA picture made up of only two colors, like black and white. Each pixel is either one color or the other.A simple smiley face drawn with a black marker on white paper is like a binary image. GridA pattern of straight lines that cross each other to form a series of squares. We use grids to organize our pixels.A checkerboard is a grid. We can put a...

The Pixel Color Rule 0 = White (Off), 1 = Black (On) When we make a binary image, we use this rule for every square in our grid. If the square has a 0, we leave it white. If it has a 1, we color it black. The Grid Reading Rule Read the grid from left to right, top to bottom. Just like reading a book, we start at the top-left square, go across the row, and then move down to the next row to understand the picture's code.
