Cell phones with higher resolution cameras are on their way, thanks to innovations from Mitsubishi
. They will begin sample production next month of a digital camera module for cell phones that has a resolution of 4 megapixels, which will open the way for cell phones with digital cameras capable of higher resolutions than the 3-megapixel class models that are currently the norm. According to Mitsubishi, each module contains a CCD (charge-coupled device) sensor and is capable of producing images of a maximum resolution of 2304 pixels by 1728 pixels. It is also possible to use the module to generate 30 frame-per-second video at VGA resolution. Mass production should begin next year.
