System-on-chip for Machine Vision Applications
CSEM has developed a unique System-on-Chip (SoC) tailored for machine vision applications in uncontrolled environments. Its 320 x 240 (QVGA) pixel array incorporating a time-domain logarithmic pixel design provides an extremely high intra-scene dynamic range (132 dB), allowing vision sensing even in rapidly changing illumination conditions. Builtin computation of contrast magnitude and direction in the readout path facilitates visual scene analysis, while the on-chip 32-bit 50 MHz icyflex DSP/MCU processor benefits from a dedicated graphical processing unit to discharge the processor from repetitive tasks (i.e. difference between two images). Named “icycam”, the SoC is optimized to facilitate image analysis and decision making.
