New Sony sensor for smartphones supports 192 off points, HDR and 4k video




Sony comes next year with a new BSI-CMOS processor with capacity of 21 megapixels and 192 integrated autofocus points. The 1 / 2.4-inch IMX230 sensor is designed for smartphones and is suitable for 4k video and create HDR photos and videos.

According to Sony itself is the new Exmor RS sensor, the first stacked CMOS sensor with 192 integrated phase-detection autofocus points distributed over the surface. The sensor would therefore be very suitable for tracking moving subjects such as children or athletes. The phase detector diodes can calculate the distance to the subject and the focus can be set faster than just contrast detection. This technique is widely used in recent system cameras. Instead of a traditional design, the BSI CMOS Exmor RS uses a chip made up of signal processing circuits, with on top a layer having rearwardly-exposed pixels.

The sensor is also able to generate images with high dynamic range, hdr. This is achieved by using two different illumination conditions and to align the signal processing on the current conditions. This ensures that highlights and shadows in high-contrast situations are recorded by more visible detail, or a higher dynamic range. This HDR function can be used for photos and videos. The video resolution is 4096×2160 pixels at 30fps, or 4k. 1080p can be recorded up to 60 frames per second and 720p is that with 120fps.

Exmor RS IMX230 BSI CMOS sensor comes in April 2015 on the market for manufacturers for a price of 2,100 yen, converted 14.46 euros. Later it would also follow a 16-megapixel version with similar specifications.
