In this lesson, you will learn about "image encoding," one of the most important topics in data representation. Rather than memorizing words alone, aim to explain the mechanisms and reasons in your own words.
Key Point
Images are represented numerically by the colors of individual pixels, and the amount of data generally increases as resolution and the number of colors increase.

Important Point
- Check the reasons, not just the conclusion
- Distinguish similar terms and exceptions
- Try applying the same way of thinking to other examples
Practice
- Explain the key point in two sentences.
- Give one common misconception and explain how it differs.
- Check it by applying it to a familiar or concrete example.
