Today Sony announced a new generation of Stacked sensor, the newly announced Exmor RS™ IMX230 sensor is small in size (1/2.4″), pixel size is 1.12μm, and features 21 MP effective megapixels, the sensor is fabricated with 192 AF points and the earlier features 179 active phase AF points, the major area of implementation of this sensor is smartphones and compact cameras…we do hope that Sony will use its new IMX230 sensor in Sony Xperia Z4 smartphone,
 The Sony will start shipping the sensor to its partners in April 2015 with a price of $18 (CNY 2,100).
Take a look at the press release
Tokyo, Japan – November 17, 2014 – Sony Corporation (hereafter “Sony”) today announces the commercialization of the Exmor RS™ IMX230 for smartphone cameras and other devices requiring increasingly sophisticated image-capture functionality. With 21 effective megapixels, this stacked CMOS imaging sensor features compact size, higher image quality, and improved functionality. This is the industry’s first CMOS image sensor for smartphones to be equipped with an onboard image plane phase detection AF signal processing function to achieve excellent focus tracking of fast-moving subjects. The High Dynamic Range (HDR) function, which captures both backgrounds and subjects clearly and vividly even in high-contrast scenes such as backlit locations, now supports high-resolution still images and 4K video recording. This new CMOS image sensor will ship in April 2015.

*2: Based on the method for specifying effective pixels in image sensors
Rather than the traditional back-illuminated CMOS image sensor’s support substrate, the Exmor RS™ uses a chip consisting of signal processing circuits, on top of which is stacked a pixel section consisting of back-illuminated pixels for an original stacked construction. This kind of stacked CMOS imaging sensor, which delivers superior image quality and high functionality in a compact size, was first commercialized by Sony in 2012.
The new IMX230 is a type 1/2.4 stacked CMOS image sensor with a significantly improved 21 effective megapixels, and it is also equipped with a newly developed signal processing function. These features fulfill the growing needs in smartphone photography for high-speed autofocus (image plane phase detection AF) and clear, high-quality capture of bright and dark areas even in backlit scenes (HDR imaging). Image plane phase detection AF is a technology used in mirrorless interchangeable-lens cameras, and HDR imaging now supports not only 4K (4096 x 2160) high-resolution videos but also still images. Sony also plans to extend the lineup by adding a 16 effective megapixels stacked CMOS image sensor equipped with image plane phase detection AF and HDR imaging functions by the end of the next fiscal year.
IMX230 Main Features
Image plane phase detection AF This function enables the camera to capture quick-moving subjects and makes accurate, high-speed autofocus tracking possible when shooting still images and videos, such as kids and animals constantly on the move and other fast subjects including athletes at sporting events. Dedicated image plane phase detection AF pixels are discretely incorporated into the screen of the image sensor, and the distance to the subject (range) and lens position for focusing are calculated based on the information obtained from these dedicated pixels. Up to 192 AF points can be used. All of this is instantaneously carried out by the stacked CMOS image sensor’s internal image processing circuits, making it easy to enjoy shooting photos and videos of fast-moving subjects on a smartphone or other device.
High Dynamic Range (HDR) imaging
This function enables the camera to record still images and videos that reproduce details and rich gradations in the highlights and shadows of high-contrast scenes, such as those found in backlit environments. This is made possible by setting two different exposure conditions and applying the appropriate signal processing to the image information obtained from each condition. Through improved pixel placement and signal processing, this new HDR imaging function is now compatible with both video recording and, by popular demand, still image capture, the latter a feature that was not available previously*3. The enhanced resolution and generation of images with a wide dynamic range enable a high level of visibility and the production of images with vivid backgrounds and subjects, even in backlit conditions. This function is also compatible with 4K (4096 x 2160) high-resolution video recording.
*3 The HDR movie function announced on January 23, 2012 supported video recording only.

Sony A5100 Press Release
Sony Debuts Ultra-Compact α5100 Interchangeable Lens Camera with Impressive Autofocus
New Mirrorless Camera Features Remarkable AF speed and tracking, 24 MP APS-C Size Sensor, BIONZ X™ Processor and more
SAN DIEGO, Aug. 17, 2014 – Sony Electronics has today introduced the stylish new α5100 camera, a new model packing pro-quality AF performance and image quality into a portable, lightweight package.
The speedy new camera (model ILCE-5100) features the same Fast Hybrid AF system as the acclaimed α6000 model, which allows it to acquire focus in as little as 0.07 seconds1. It also shares the α6000’s image sensor – a 24.3 MP APS-C Exmor™ CMOS sensor – and powerful BIONZ X processor. This impressive combination of hardware ensures that the camera can capture still images and full HD videos in sharp focus with incredible detail.
Unique to the new α5100 is its extremely compact design, placing it among the smallest and lightest interchangeable lens cameras in market today.
“Sony continues to innovate in the mirrorless camera space, offering products that are not only smaller and lighter than competitive DSLRs, but that consistently outperform them,” said Neal Manowitz, director of the interchangeable lens camera business at Sony. “The new α5100 is a primary example, offering world-class AF speed and performance in a palm-sized body at a great price. It’s powerful enough to satisfy the most experienced DSLR shooters, yet not too intimidating for the casual weekend photographer.”
Fast Hybrid AF system
Borrowing from the award-winning α6000, the compelling Fast Hybrid AF system on the new α5100 camera features focal plane phase-detection AF points with an extremely wide autofocus coverage area (179 focal points) that is teamed with high-precision contrast-detection AF. This potent combination allows the camera to accurately track and respond to a subject moving through nearly the entire frame, whether shooting still images or full HD videos.
Additionally, the α5100 camera has an extremely responsive touch screen which works with the AF system to enable Touch Focus, allowing shooters to focus by simply touching the intended subject on any area of the LCD screen – even if it’s at the far edges.
The new α5100 model also comes equipped with Eye AF and Lock-on AF functions that debuted in the α7/ α7R, a Flexible Spot AF area function, and AF-A mode (automatic switching between AF-C and AF-S) that is also offered in the α6000.
HD Video Performance
The versatile α5100 supports full HD video shooting in AVCHD as well as the XAVC S2 codec, which records video at a high data rate of 50 Mbps with advanced compression for impressive video quality. XAVC S paired with the advanced focusing system of the α5100 makes for a compelling HD video shooting solution that only a select number of cameras in market today – mirrorless or DSLR – can offer.
Additionally, with the power of the BIONZ X processor, the camera is able to read, process and output data from all of the sensor’s pixels during video recording, ensuring that it produces the highest quality video possible by eliminating aliasing, moiré and false color artifacts.
The new camera also features dual video recording, allowing it to simultaneously record two files – one in Full HD (AVCHD or XAVC S) and the other in lower resolution MP4 format – to a single installed SD card2. This gives videographers a high-quality file for viewing on large screens or working on in post-processing, as well as a smaller, lower data-rate version that is ideal for uploading and sharing.
Design, Controls, Wi-Fi® and New Accessories
The compact new mirrorless camera features a high resolution 921k dot WhiteMagic™ LCD screen that can tilt a full 180 degrees upright, ideal for self-portraits. On top of the camera body, there’s a zoom lever for convenient one-handed camera operation and a handy pop-up flash for tough lighting conditions.
The α5100 camera has built-in Wi-Fi, giving consumers one-touch connection with Xperia® or NFC-compatible Android™ smartphones or tablets for instant image transfer and sharing. A single touch also activates Smart Remote Control, giving users a live image preview through their compatible smartphone or tablet, and allowing them to use the smart device to release the camera’s shutter.
For devices without NFC one-touch capabilities, users can wirelessly transfer images and videos and activate Smart Remote Control through Sony’s free PlayMemories Mobile™ application, available for the iOS and Android platforms.
The camera is also compatible with downloadable Sony PlayMemories Camera Apps, adding a range of exciting and creative capabilities. Currently there are a total of 10 different applications available with several others to be released this spring. Learn more at www.sony.net/pmca .
New accessories that are compatible with the α5100 camera include the style-matching LCS-EBD body case – available in three color variations – as well as the compact, easy-to-carry RM-SPR1 remote.

In general as we know that the sensor phase AF pixels doesn’t capture image, they create a dead pixel and later on it covered by certain type of image processing algorithms implemented by camera manufactures.
But Fujifilm latest patent shows a Hybrid AF pixel that minimizes the image quality degradation and manages to capture light as well as it can be used for AF purpose.
Patent Details translated by google
Explanation and self-interpretation of the patent literature
- Patent Publication No. 2014-135451,2014-135451
- Published Date 2014.7.24
- Filing date 2013.1.11
- Fujifilm patents
- Image plane phase difference AF
- Dimming element
- The amount of transmitted light is changed according to the voltage applied
- Electrochromic devices were laminated in this order the transparent electrode, the oxidation coloring layer, an ion conductive layer, the reduction coloring layer, a second transparent electrode of the first
- Opaque, to function as a transparent at the time of imaging the image plane when the phase difference AF
Canon is the first Camera manufacture to implement Hybrid AF Pxiels technology
Canon is first camera manufacture to use Hybrid / Dual-AF pixel technology, the Canon Dual-Pixel AF technology features two separate photodiodes for each pixel. One half of the total photodiodes track image coming from one side and other half tracks the image from the other half and finally the amount of lens drive is calculated from the amount of signal difference. When the signals of two photodiode are in agreement the Focus is achieved.

Canon 1DX Mark II and Canon 5D Mark IV is rumored to announced Q4 of 2014 or Q1 of 2015, both camera will carry a newly designed sensor and improved core specification.
The rumor look bit true to me since all the Fullframe DSLRs of canon (6D, 5D Mk III and 1DX) is using old type CMOS sensor that doesn’t support Hybrid AF system, on the other recently announced DSLRs (including 100D) features advance sensor design that supports Hybrid AF, for example Canon 700D / T5i and 100D / SL1 is using HYBRID CMOS AF sensor and recently announced Canon 70D features Dual Pixel CMOS AF Sensor. So Canon will sure upgrade its High-End fullframe DSLRs to implement the new sensor technology.
