A group of engineers from Omnivision has founded Cista System Corp., based in San Jose, CA. The founding group is Zheng (Wilson) Du (former Module Development Manager at Omnivision), Jiangtao Pang (former director of Product Design at Omnivision), Guangbin Zhang (former Analog Design Manager at Omnivision). The new company has raised $5M in round A at the end of 2013 and joined MIPI Alliance with the adopter status.
It's not clear what the new company is working on, but Guangbin Zhang's LinkedIn page says that he has "invented new sensor readout structure with 5 pending patents. More fundamental innovations are on the way."
