“Each pixel individually controls its sampling – with no clock involved – by reacting to light, or changes in the amount of incident light it receives,” explained Posch, Chronocam’s CTO.
“Frame-based video acquisition is fundamentally flawed,” Chronocam CTO Posch decreed.
Chronocam has applied and tested its sensor’s principles in restoring people’s vision at Pixium Vision, a retina prosthetic company founded by Chronocam’s co-founders.
Chronocam has raised 1.5 million euro so far. Among investors are CEA Investment and Robert Bosch VC.
Chronocam’s CCMA ATIS 1.1 sensor, whose supply voltage is 3.3V (analog), 1.8V(digital), comes in a 9.9 x 8.2mm2 chip size, featuring 2/3-inch optical format. Its array size is 304 x 240 QVGA, with a pixel size of 30μm × 30μm. The power consumption is less than 10mW.
Asked about the company’s next steps, Verre, the CEO, said, “We aim at decreasing pixel pitch and increasing resolution. Our next steps are the VGA tape out and the migration to a CIS process.”
Chronocam is open to licensing its technology to others."
