Fuji and Panasonic announce new partnership and new organic sensor technology!


This is a hell of a news! First Fuji and Panasonic announced a new partnership. And the second big news is that they have already developed the first organic sensor! Here is the press release that explains all the advantages of the new sensor tech:


Here is the Press release (via Fujifilm):


FUJIFILM Corporation (President: Shigehiro Nakajima) and Panasonic Corporation (President: Kazuhiro Tsuga) have developed organic CMOS image sensor technology that uses an organic photoelectric conversion layer with a photoelectric conversion property at the light receiving section of an image sensor to achieve performance beyond that of conventional image sensors**. Applying this technology to the image sensors of digital cameras and other imaging devices expands its dynamic range*** and enhances sensitivity*4 further to prevent highlight clipping in bright scenes and capture a dark subject with vivid colors and rich textures.

The industry has put into continuous efforts to explore image sensor technologies for increasing their number of pixels. This has dramatically improved sensor resolutions, but, in order to further boost image quality, it is necessary to expand the dynamic range, enhance sensitivity and prevent cross-talk or color mixing between pixels. Panasonic took advantage of its semiconductor device technology to boost image quality for its high-performance image sensors. Fujifilm, on the other hand, has developed highly-reliable organic photoelectric conversion layer with high absorption coefficient to be used on a sensor’s light receiving section instead of silicon photodiode*5 in its effort to build a new image sensor technology.
In the latest collaboration, Fujifilm and Panasonic have combined Fujifilm’s organic photoelectric conversion layer technology with Panasonic’s semiconductor device technology to jointly develop an organic CMOS image sensor that outperforms conventional image sensors. The new organic CMOS image sensor offers the industry’s highest dynamic range of 88dB, advanced sensitivity 1.2 times more sensitive than conventional sensors** and broader range of incident angle*6 to enable the production of more sensitive and compact cameras with better image quality.
The two companies will promote the application of this organic CMOS image sensor technology to a wide range of products including security cameras, in-vehicle cameras, mobile device and digital cameras.

Fujifilm and Panasonic will present the research results at the 2013 Symposium on VLSI Technology (VLSI2013) to be held in Kyoto on June 11, and the 2013 International Image Sensor Workshop to be held in Utah, U.S.A. on June 15.

  • *Performance of the light receiving section of image sensors, as of June 11, 2013 according to Panasonic data.
  • **Estimation from Panasonic image sensors
  • ***Range of light that can be recorded (ratio between the brightest and darkest areas recorded)
  • *4The sensitivity of image sensors refers to the conversion ratio of light into electric signals. The greater the sensitivity is, the clearer you can capture low-light scenes.
  • *5A type of photo detector that senses incident light, installed for each image sensor pixel to convert light into electric signals
  • *6Range of incident light angles for efficient conversion into electric signals

Overview of the newly-developed organic CMOS image sensor technology

A conventional image sensor consists of a silicon photodiode for capturing light, metal interconnect, color filter and on-chip micro-lens. The newly-developed organic CMOS image sensor technology uses organic photoelectric conversion layer with high absorption coefficient instead of the silicon photodiode, reducing the thickness of the light receiving section down to 0.5 microns, i.e. one severalth of the thickness of a silicon photodiode. This structure provides the following benefits:

  1. (1)Industry’s highest dynamic range of 88dB to prevent highlight clipping and produce a vivid and texture-rich image even in low light
Panasonic’s semiconductor device technology has improved the signal saturation value*7 by four folds compared to that of conventional image sensors. Coupled with the newly-developed noise-cancelling circuit, the sensor technology provides the industry’s highest dynamic range of 88dB, preventing highlight clipping in bright scenes and capturing a vivid and texture-rich image in low light.
  • *7The maximum amount of electric signals that can be handled. Receiving a signal greater than this value leads to highlight clipping.
  1. (2)1.2 times higher sensitivity than conventional sensors to capture clear images even in low light
The transistors and metal interconnects in each pixel, fabricated using Panasonic’s semiconductor device technology, are coated with photoelectric conversion layer, developed using Fujifilm’s organic material technology. The area of the light receiving section becomes limited in conventional image sensors because of the existence of metal interconnects and the need to form light shield film to prevent light incidence into areas other than the photodiode in each pixel. However, the organic CMOS image sensor technology coats the sensor with organic film, which can harvest all the light received on the sensor. This boosts sensor sensitivity by 1.2 times compared to conventional sensors to deliver clear images even in low light.
  1. (3)Range of incident angle expanded to 60 degrees for faithful color reproduction (See the image sensor illustrations above)
The thickness of the organic film with high absorption coefficient, developed by Fujifilm, has been reduced to just 0.5 microns, or one severalth of the thickness of silicon photodiode in the light receiving section. Since the conventional silicon photodiode measures at least 3 microns in depth, the range of incident angles was limited to around 30 – 40 degrees. The thin film, achieved with the organic CMOS image sensor technology, has enabled the expansion of this range to 60 degrees, efficiently utilizing light entering at an angle for faithful color reproduction with no color mixing. It also gives greater flexibility in lens designs, facilitating the reduction of overall camera size.
  1. (4)Offering high reliability for broader applications
Fujifilm has developed a process technology to produce inorganic films for protecting the organic film. It prevents the entry of moisture and oxygen into the organic film to safeguard it against performance degradation. The sensor technology has cleared reliability tests involving the application of stress such as temperature, humidity, electrical voltage and light, paving the way for the use of the organic CMOS image sensor in a wide range of applications.

    Good, Panasonic can give Fuji a clue on how to implement video modes.

    GF1 is 4 years old and blow every Fuji camera out of the water on video.

    Such an achievable and valuable addition for many many buyers.

  • Jason

    please combine this with on sensor phase detection and put that in XPRO2!

    • I guess they will start with smaller sensors until the production is reliable enough to produce large sensors with a low error rate.

      • Renato S.

        And they said it would take 1~2 years to enter production

    > Range of incident angle expanded to 60 degrees for faithful color reproduction (See the image sensor illustrations above)

    This is the biggest win for me. It will mean that rangefinder lens won’t have shitty performance on Fuji cameras any more.

    • MJr

      This! But how long will we have to wait? Highly doubt it’s ready for X-E2 / X-Pro2. :/

  • Anton

    I’m not sure that panasonic can produce good sensors, 1.2 extended sensitivity compared to other panasonic sensors means that sensitivity will be worse than sony’s sensors have(

    • JOE

      panasonic will plan use outsource manufacturing,
      it will be next section,in news this prototype develop by panasonic semiconductor factory.

  • MJr

    Damn. Apart from dynamic range. The big news is how this enables the light sensitive layer to be shifted way up. Thickness is what can completely ruin or maximize lens performance. Should avoid scattering of light onto the ‘wrong’ pixel.

    Too bad it’s probably not tested well enough for any apsc size sensor this year. Wonder if there’s any difficulty to combine this with x-trans at all.

    • peter

      X-Trans is just a high-level layout of color filter array. It doesn’t depend on type of sensor and can be used with just about any sensor technology.

      • MJr

        Probably. But things are not always what they seem. :P

  • Mike

    …old story…this organic sensor…old patent (2011 but never made by fuji)

    Fujifilm patents hybrid organic/CMOS sensor – Dec 21, >>>2011<<<< at 19:16:13 GMT


  • Markdphotoguy

    Great news! This technology is probably why Fuji stated that there will be no X-Pro2/X-E2 until 2014 (late) worth waiting for in my opinion. 88dB is a lot of DR.

    • MJr

      Wait, when did they state that ?

  • Guess we gonna see an X-Trans filter array on organic backlit sensor with built-in PDAF in a 3rd generation of X-cams. Good.

    DSLR is dead, now Leica is dead, too (with their incidence angles and uber expensive ways to solve that). Bring it on! :)

    • tikox

      Hmm, I would like to see micro splitters too ;) combination would be overkill.


      • All right, now let’s repeat it again, all together…
        Dear FujiPanaSanta!… :)

    • Mike

      DSLR Dead? I love fuji products but it’s to early to speak about DSLR future.

      Canon and Nikon can invest a lot of money in a new sensor project, if they want.

      Canon has already announced a new sensor generation project

      I think we will not see this “new organic-sensor” until the x-pro 3 model …late 2015

      Now I want 23 1.4 and 10-24…no sciencefiction organic-borg-sensor

  • xpro

    The wider angle of incidence is big news. This could help Fuji cost effectively put a full frame sized sensor into a rangefinder-type body less expensively than how leica dealt with that issue.

    For a much-needed reality check, have a look at Thom Hogan’s site. No need for Nikon D800 owners to trash their cameras.
