This article reports on the development of image sensors for mobile devices in 2005. The insatiable demand for Web cameras, digital cameras, and mobile phones is powering a quiet revolution in the design and development of image sensors for mobile devices, according to Vivek Sharma, director of the India Design Center of STMicroelectronics. The main challenge is to control the power consumption of the image-signal processor, because battery power is at a premium in mobile-system applications, he says. Meanwhile, Insilica Semiconductors, says processing moving images and video at higher frame rates and sizes, implementing nonmechanical optical-zoom functions, increasing pixel count, and keeping costs reasonable are the main objectives.
