Sony has introduced a new image sensor for smartphone cameras which could bring some of the features found in high-end, mirrorless cameras to smartphones.
The Sony Exmor RS IMX230 image sensor should be available starting in April, 2015.
The sensor supports 21 megapixel images, but it takes more than megapixels to make a good photo. The IMX230 uses a stacked CMOS sensor with mirrorless-camera style image plane phase detection for auto-focus, built-in support for HDR (high dynamic range), and 4K video recording, among other things.
In plain English, that means the IMX230 should enable high-speed autofocus detection so you can track and shoot moving targets quickly. The HDR imaging function lets you capture still pictures or videos with a wide range of colors including shadows and other gradients in a backlit environment.
Sony also plans to launch a 16MP version of its Exmor RS image sensor.
I wonder how they solved the noise problem when you pack that many megapixels into such a small package.
BSI-sensors is flip chip which are stacked in some chip layers.
BSI cam sensors are like todays Nand Flash memories stacked on top of each other.
BSI-sensors have conductors on the backside of the BSI-sensor and usually is the A/D-converter on the next chip under BSI-sensor chip.
Search on google maps about BSI-sensor architecture!
When will they begin putting Four Thirds sensors in phones?
never because there is not enough space for the needed lenses…
