STM's Image Processor Measures The Distance Between Display And Viewer

STIMicroelectronics (STM) has come up with an image processor that can determine the distance between a display and a viewer and it’s currently being demonstrated at the FPD International 2010/Green Device 2010. The processor is targeted at TVs, PCs and similar devices with the company expecting it to be used to estimate the distance between a screen and viewer by using images taken by a camera embedded in the device. A TV or PC with this chip would be able to adjust the volume of the speakers and 3D effects accordingly and when a user moves parallel to the screen, the volumes of the left and right speakers can be controlled separately too. Another use of this image processor is to adjust the brightness of an LED backlight of an LCD panel, depending on how close the user is. STM will be supplying the image processor, though it will not include the camera module and it aims to commercialize the processor within 2011.
