Sure, it was once a popular resolution for existing optics and relatively large available pixels, then went out of fashion when people figured out how to make smaller pixels.<br /><br />The real story here is the short optical stack. Probably to make a camera module that is 2.2 mm thick and that meets routine field-of-view requirements, you need to have a very small focal plane area, and VGA resolution is maybe a best result you can get using 1.75 um pixels. (My guess is that the company picked VGA as a well-known, easily-marketed resolution and then determined the module height accordingly.)<br /><br />So, this VGA chip is likely a high-cost, high-margin product, not one that will be competing with low-cost, low-margin, physically-larger VGA chips.<br /><br />As an afterthought, I don't have and never have had stock or another financial interest in OmniVision or any of its competitors.CDMhttps://www.blogger.com/profile/16405088162729045793noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-76742813107290260752010-08-18T20:18:29.815+03:002010-08-18T20:18:29.815+03:00Wild guess : What is the buyer of OV7727?
