STMicroelectronics has developed a new chip to boost light output from LED-based flashes available in smartphone cameras. Professional cameras use a xenon strobe light to produce a brief burst -- or flash -- of light, but the lighting on smartphone cameras is typically provided by an LED. The light output of a battery-powered LED is continuous, and much lower in intensity than a flash, leading to longer exposure times and darker, blurrier pictures. But ST hopes to change that with its new STCF04 multifunction chip, which it says can control flash power up to 40W, ...
