Digital images are arrays of discrete samples (pixels), each representing intensity or color. Grayscale images store a single intensity value per pixel, while color images typically use multiple channels (e.g., RGB). Key representation considerations include spatial resolution (number of pixels), intensity resolution (number of gray levels or bits per pixel), and image formats (raw, TIFF, JPEG, PNG). Sampling and quantization convert continuous scenes into digital form; improper sampling causes aliasing, while coarse quantization produces contouring and loss of detail.
