Sony Unveils IMX318 22.5 Megapixel Exmor RS Mobile Camera
Sony today announced a new Exmor R sensor for mobile devices.The sensor will be called the IMX318 and it is the first stacked CMOS sensor with integrated hybrid autofocus and 3-axis electronic image stabilization. The IMX318 is a 1/2.6 type sensor with an effective resolution of 22.5 megapixels. It has a pixel pitch of 1.0 micrometre.
A statement from Sony talking about this launch read,
“The IMX318 boasts a stacked structure and the industry’s smallest unit pixels, which measure 1.0 micrometre in size. With this, the image sensor achieves a compact, type 1/2.6 size suitable for inclusion into smartphones, while still realizing a high resolution of 22.5 effective megapixels, among the top in the industry.”
The sensor is expected to be used in the upcoming Sony Z6, and what’s so exciting about this that it has built in hybrid AF. Sony IMX318 is the first to incorporate this within the sensor’s internal signal processor. The company claims this will result in a focusing time of 0.03 seconds for stills and as fast as 0.017 seconds during 60fps video.
The other major talking point about this sensor is the inclusion of the integrated 3-axis image stabilization. The sensor can correct for pitch, roll, and yaw by taking the input from an external gyro sensor and processing it within its own internal signal processor. This will be more energy efficient as compared to software processing.
