Developing intelligent, high-performance vision systems is complex and typically takes about half a year. Accelerating the time to market for such vision systems and optimizing engineering resources are critical to the success of complex vision designs. To better support camera development, ON Semiconductor has created a reference module ecosystem for image sensors called the Premier Reference Image Sensor Module (PRISM). This article will take you through the PRISM ecosystem, including its benefits and usage guidelines.

PRISM and its advantages

PRISM is a pre-optimized subsystem solution developed using ON Semiconductor's industrial and consumer image sensors. In addition, every new sensor launched by ON Semiconductor will support PRISM as standard. These modules, combined with hardware adapters and ecosystem partner development kits, can be used to build prototypes, shorten the prototyping process, and thus speed up the time to market.

A typical vision system consists of many elements, including optical components (lenses), image sensors, sensor interfaces, image signal processors, and application software or artificial intelligence (AI). The lens and sensor must be highly matched within the appropriate size range to ensure the quality of the input image. Any slight matching error may cause artifacts and affect the overall system performance.

In addition to the module, ON Semiconductor also provides supporting documentation that details how to further develop PRISM to meet the requirements of mass production. After signing a non-disclosure agreement (NDA), we can provide a verification report of the sensor performance benchmark data. We also provide a standardized interface for the PRISM adapter to connect PRISM to major AP/SoC platforms.

Figure 2 below briefly shows the various stages of PRISM ecosystem design.

Premier Reference Image Sensor Module

The following is an introduction to all ON Semiconductor image sensor modules supported by the PRISM ecosystem.

PRISM1M-AR2020CSSC130110-GEVB: This high-resolution 20MP module is designed, built, and validated for applications such as video conferencing endpoints, AR/VR headsets, etc. Its innovative SmartROI feature enables 20MP without increasing bandwidth requirements. We provide sensor drivers and basic tuning for mainstream SoC platforms.
PRISM1M-AR0830CSSC130110-GEVB: This 8-megapixel sensor is designed, built, and validated to provide lower power consumption, better imaging performance, and lower system cost for applications such as video doorbells and smart access control. It also features a wake-on-motion feature, so it consumes less power than similar sensors in the industry.
PRISM1M-ARX383CSSM130110-GEVB: This tiny 0.3-megapixel global shutter module featuring the ARX383 image sensor is designed, built and validated to deliver excellent benchmark performance for size-constrained applications including handheld QR code scanners, autonomous driving, and more.
PRISM1M-AR0145CSSM130110-GEVB: This 1-megapixel global shutter module is designed, built, and validated to provide excellent benchmark performance for applications such as barcode readers and autonomous mobile robots.
PRISM1M-AR0235CSSM130110-GEVB: This 2-megapixel global shutter module based on the AR0235 image sensor is designed, built, and validated to provide excellent benchmark performance for applications such as barcode readers and autonomous mobile robots.
PRISM1M-AR0822NPSC130110-GEVB: This 8MP module is designed, built and validated with excellent baseline performance for applications that require built-in high dynamic range sensors, especially multi-camera systems. Such multi-camera systems typically consume data transmission bandwidth between the sensor and the ISP/SoC. Whether single or multi-camera design, the AR0822 can help optimize HDR with its built-in eHDR and significantly reduce bandwidth requirements.
