If you thought Apple making an was wild, wait until you hear this.
Similar to Apple's claim that taking out the headphone jack allows for bigger batteries and other parts to be put in, Hitachi says cameras that use this lensless tech will be considerably slimmer and lighter.
Lensless cameras are possible thanks to a pattern development technique called "Moiré fringes" -- you can find the company's explanation, rife with technical mumbo jumbo, here. Hitachi is planning on making cameras that use this technology by 2018.
The company also hopes to utilise lensless photography in automated driving, vehicles and robotics. With surveillance tech such as CCTV, faces of people are often blurred due to low focal ranges. With Hitachi's lensless camera tech, for instance, still images could theoretically be adjusted on the fly from a range of depths to identify people more clearly.
