An Australian Koala can be seen on a Sony Corp tablet screen while sitting atop a branch eating eucalyptus leaves in its enclosure at Wild Life Sydney Zoo April 3, 2014. Images from the camera, which are triggered by the koala's movements, are displayed on a nearby small screen which the zoo is promoting as a koala "selfie". Sony Corp is counting on the boom in smartphones and the market's voracious appetite for megapixels - vital to better quality video calls and "selfies" - to sustain the double-digit revenue growth in its image sensor business.
