Sony reveals 21MP 4 Thirds stacked CMOS sensor able to 120 fps full-width readout: Digital Pictures Overview


Sony Semiconductor Options has printed a product data sheet detailing the specs for the IMX472-AAJK, a 21.46MP 4 Thirds stacked CMOS picture sensor. Because it stands, that is the primary identified occasion of a stacked CMOS sensor for 4 Thirds-sized cameras and the accompanying readout speeds makes for some spectacular imaging capabilities.

Nevertheless, regardless of velocity that might underpin spectacular video (and AF) capabilities, the pixel rely seems to be too low to ship the ‘5.7K’ output promised of the forthcoming Panasonic GH6.

The IMX472-AAJK measures 21.77mm diagonally and contains a whole of twenty-two.93M pixels, with 21.46M efficient pixels and 20.89M lively pixels. The sensor contains a 27dB Programmable Acquire Amplifier (PGA) circuit and 12-bit A/D converter with a 14 lane (8 lane + 6 lane) Scalable Low-Voltage Signaling with Embedded Clock (SLVS-EC) interface. This all provides as much as the sensor with the ability to readout 12-bit photographs as much as 20.89M pixels at simply over 120 frames per second (fps) and 10-bit photographs at simply over 158 fps.

A full breakdown of the readout speeds at varied resolutions and bit-depths.

What this implies is the sensor ought to be capable to provide full-width oversampled 4K video at as much as 120 fps with full dynamic vary. It additionally means it may enhance Panasonic’s Depth From Defocus (DFD) autofocus efficiency, ought to this sensor be utilized by Panasonic in a future GH-series digital camera system.

This particular model of this sensor additionally seems to have readout modes particularly designed for phase-detection autofocus programs. That does not essentially imply we’ll see that in any forthcoming Panasonic cameras, however OM Digital Options, however, may have one thing up their proverbial sleeves.

The product data sheet reveals the ‘AAJK’ variant is a Quad Bayer sensor, however it’s not out of the realm of potentialities for a standard Bayer model to be obtainable for digital camera producers as effectively. As an illustration, the specs of the Quad Bayer IMX299CJK line up extraordinarily effectively with these of the traditional Bayer sensor utilized in Panasonic’s GH5S.

Sony Semiconductor Options doesn’t specify when this specific sensor can be obtainable to digital camera producers within the product data sheet, however traditionally talking, if it’s on the Sony Semiconductor Options web site, it’s possible already obtainable to prospects.
