Let’s start with your customers, who fall into different market segments. Some customers want proven products, while others are biased towards miniaturization or high speed. Segments are named for their customers' top concern and are called:

• TRADITIONAL
• LOW END
• HIGH END
• PERFORMANCE
• SIZE

These segments can be visualized using a perceptual map, which plots two design attributes, the sensor’s size and its performance. The circles represent groups of customers. They cluster near the design attributes they want. These clusters are called Market Segments.
