Sony subsidiary Softkinetic presents a BSI ToF sensor with a 10µm pixel pitch, which the company calls "the industry's smallest". As as side note, Microsoft Kinect 2 camera has 10um ToF pixel too, available on the mass market since 2013. The Softkinetic's proprietary Current Assisted Photonic Demodulator ("CAPD") pixel architecture is capable of 100MHz high-speed modulation using drift current in the pixel, allowing for 1.5x longer distance. The new pixel light collection efficiency is equivalent to that of a 15µm pixel pitch FSI sensor, but using a BSI with a 10µm pixel pitch.
Why the detail of the object can not bee seen clearly even if the depth accuracy is so fine?
ReplyDeleteThe depth range is too large
DeleteThere's only a little depth range from green to red in the map image. Nothing "too large" shown.
DeleteSeems like an issue with the colormaps used for the demonstration.
ReplyDeleteThe comparison is a mix of pixel scaling effects and different technologies. A comparison between conventional 10um pixel with microlense and BSI 10um would be appropriate to indicate the gain from BSI.
