Bandwidth
Bandwidth = # pixels per frame (resolution) x frames per second (frame rate) x # color bits per pixel (color depth)
For example, Bandwidth required by 1080p video = 2.07 megapixels x 30 frames per second x 24-bit color = 1.5 Gbps

Compression
Reduces the Bandwidth requirement of an image using a mathematical algorithm
Modifies pixels, irreversibly degrading image quality
Requires a Compression engine, usually implemented with an FPGA or ASIC plus DRAM
CSI-2 (Camera Serial Interface v2.0)
A specification that defines the standard data transmission and control interfaces between an image sensor and an image processor
Includes a unidirectional serial interface for data and clock signals, and a bidirectional I 2C interface for control signals
Image Signal Processing (ISP)
Operations that turn raw data produced by an image sensor into digital images
Mobile Industry Processor Interface (MIPI) Alliance
An open-membership organization that develops interface specifications for the mobile handset industry

Design Problems Engineers Face
1. HD video requires 1.5-Gbps Bandwidth
USB 2.0 Bandwidth is only 480 Mbps
USB 2.0 thus requires Compression, which degrades image quality
2. Conventional USB camera solutions are not programmable
Fixed-function USB camera chips support UVC only
Advanced camera features (e.g., pan, tilt, zoom control) or customizations (e.g., USB3 Vision) are difficult to implement
3. High-resolution image sensors are going serial
Image sensors greater than 3 MP use CSI-2 instead of a parallel interface
Many use up to four CSI-2 lanes to support higher image resolution
Cypress’s CX3 solves these problems by:
Delivering uncompressed HD video at the required Bandwidth
Providing an ARM9 CPU and SDK to support camera customization
Providing four CSI-2 lanes to interface with any image sensor
Cypress’s CX3 enables you to design advanced features into any USB 3.0 video camera
