Even the technically challenged among us know that digital cameras use no film. Instead, such devices record pictures on solid-state silicon chips called image sensors. One of the best known manufacturers of such chips is headquartered in Sunnyvale, California.

These capture and convert images for such consumer instruments as cameras, surveillance systems, games, videophones and medical imaging units.

The company pleased investors last week, when it reported Q1 EPS of 23 cents and revenues of $173.1 million. Analysts had been looking for 8 cents and $160.2 million.
