ams: embedded vision comes to space-constrained consumer and industrial systems

ams announced the pre-release of the NanEyeM, a miniature integrated Micro Camera Module assembly with a tiny footprint at the image sensor end of just 1mm2 . With its compact design and convenient interface, the NanEyeM is easy to integrate into space-constrained industrial and consumer designs, providing new embedded vision capabilities in products such as smart toys and home appliances.

The NanEyeM offers a high-resolution 100kpixel, 10-bit digital readout, and features a Single-Ended Interface Mode. Like a standard Serial Peripheral Interface, the SEIM channel is easy to implement in any host processor and provides a cost-optimized solution without the need for LVDS deserialization. The maximum frame rate over the SEIM interface is 58 frames/s at a clock rate of 75MHz.

The NanEyeM features a custom multi-element lens which greatly improves the effective resolution of the sensor and reduces distortion compared to competing sensors that have a single-element lens. The MTF (Modulation Transfer Function) is >50% in the corners, distortion is <15% and color aberration is <1Px. The slave configuration in SEIM enables control of the frame rate via the host application processor, down to rates of a single frame per second or even slower. Synchronization of two or more cameras – a useful capability in applications such as eye tracking or stereo vision – can easily be performed by providing a centralized clock from the application processor.

The NanEyeM also offers an Idle mode which reduces power consumption in applications, such as presence detection, that require only a small number of frames per minute. ams will offer a reference implementation of image acquisition and processing functions on a standard Arm core-based processor to reduce the customer’s development effort and accelerate time to market.
