This document explores the fundamentals of digital image encoding and storage. It includes exercises that discuss the differences between analog and digital signals, with a focus on binary coding and bit-based representations of grayscale or color images. The document uses the example of the Game Boy's 160x144-pixel display, explaining how pixel grids and bit encoding translate to image resolution and storage requirements. Additionally, it extends to explain RGB coding for colors and how newer Game Boy models improve image quality by increasing resolution.
