Psych221 Camera Design

Imagine that you work for a cell phone company and you have been assigned the task of selecting the components for a camera that will be built into the phone. Because you work for a large vendor, you have parts suppliers calling you every day encouraging you to purchase their devices. Typically, these suppliers offer one component and it is your job to assemble a large variety of components into a working system.

In this project you will be asked to develop a method to make these purchasing decisions. Specifically, you will have to decide on which lens, anti-aliasing and IR filter, sensor, and color filter array you would like to use for your system.

Test Scenes and Images

The test images should include

• Macbeth (Gretag) Color Checker
• Slanted Bar target
• Uniform field
• A high dynamic range multispectral image.

Each of the scenes can be generated using the ISET function sceneCreate.

Evaluation Methods

The way you decide to evaluate the assembled components is crucial. We will ask you to explain your choice. In choosing the methodology, you must include assessments of

• Color accuracy
• Signal-to-noise
• Dynamic range
• Spatial resolution (blur)
