Infineon Technologies has released a family of 3D image sensor chips for touchless gesture recognition. Developed in cooperation with pmdtechnologies, the new chips are the first to combine a 3D image sensing pixel array with the digital conversion and control functions needed to develop very compact and accurate systems for gesture recognition applications in computers and consumer electronics devices.
The chips include a photosensitive pixel array, sophisticated control logic, digital interfaces with A/D converters and digital outputs. The IRS1010C has a resolution of 160x120 pixels, while the IRS1020C has a resolution of 352x288 pixels. Both are dynamically configurable via an I²C interface, allowing real time adaptation to changing lighting conditions or operating situations. The chips are supplied as bare dies for integration with a camera lens and infra-red illumination source in a camera module.
