It looks like OmniVision Technologies
I've been busy explaining how the company's back-side illumination (BSI) camera chips are the key to OmniVision's future, and how none of the usual suspects are even close to challenging OmniVision's first-mover advantage. But Sony
The available sources don't specifically say that Sony is investing in BSI chips, but the chip volumes they're talking about point to products that Sony isn't making a whole lot of today. Bog-standard camera chips are a dime a dozen these days, and Sony has already made noise about increasing its market share of mobile image processors from 10% to 30%. Given these facts, I think it's safe to assume that Sony is going after OmniVision's bread and butter.
Before you panic and hit the "sell" button on OmniVision, consider that Sony, Panasonic
Whether Sony eventually closes the gap or just ends up throwing good money after bad, OmniVision holds a winning hand just as the smartphone phenomenon hits the tipping point, and is the camera chip supplier for trendsetter Apple
Fellow Fool Tim Beyers likes OmniVision so much, he added the stock to his CAPS portfolio. I'm doing the same right now, because the market is overreacting to the Sony attack and giving me a nice entry point. This should bolster my All-Star CAPS status a bit, and you're welcome to join me right now.
