Canon shows off its latest CMOS sensor tech in new promo video

Canon isn’t only in the business of making DSLR, mirrorless and point-and-shoot cameras. It’s also in the business of making the CMOS sensors inside those cameras—arguably the most important component. And in order to showcase what its achieved with its latest lineup of CMOS sensors, Canon USA has created a little promotional video.

The video showcases a variety of sensors seen across Canon’s product line, from the extreme low-light full-frame sensor it showed off earlier this year, to more industrialized CMOS sensors made for surveillance and security purposes.

The video description from Canon USA:

This video showcases Canon variety of sensors. For several decades Canon has been developing and manufacturing advanced CMOS sensors with state-of-the-art technologies for exclusive use in Canon products. These sensors are a critical driving force behind many of our successful product lines, ranging from consumer products all the way up to high-end business and industrial solutions.

The video does seem a touch overly dramatic for what it is, and may even come across as a bit cheesy at times (why are they showing new sensor tech inside a Canon EOS 1D that came out in 2001?). Nonetheless, it’s an interesting watch that gives a good overview of the work Canon has been putting into its CMOS sensors in recent years—technology that will hopefully impact the Canon DSLRs and mirrorless cameras of the future.

You can own the world’s first single shot 8×10 digital camera for $106,000

If you’re shooting digital, the largest image sensor you will find at your local camera store is the 53.4mm x 40.1mm medium format sensors inside something like the Phase One IQ3. But if that is just not enough for you… there is one, much larger option. Meet the $106,000 LargeSense LS911: a large format digital camera and purportedly the “world’s first 8×10 digital single shot camera for sale.”

The LS911 is the passion project of Bill Charbonnet, who left his desk job in 2014 to start LargeSense LLC and built these large-format digital cameras. Four years later, the LS911 is his first shipping product.

According to the press materials, LS911 features a 12-megapixel 9×11-inch monochrome CMOS sensor (that translates into massive 75 micron pixels), ISO that can be set at either 2100 or 6400, 900GB of internal storage, and the ability to output files to DNG, 16-bit TIFF, 32-bit TIFF, RAW and JPEG formats. There is no CFA, but the monochrome sensor can be used to produce color images (of non-moving subjects) using an in-built 3-shot system and color filters.

Oh, and the thing can also apparently shoot 4K, 3840 × 2160 video at 26fps using its electronic shutter.

Here is a video of the LS911 in action:

And here is how the size of the LargeSense LS911 sensor compares to some of the other image sensors out there:

Note: the LargeSense LS45 is a 4×5-inch digital back Charbonnet is working on, but has yet to release.

If the LS911 seems a bit bonkers, honestly, that’s because it is. We’ve been discussing it in the office for the past couple of days, trying to figure out how to put this camera in context for our readers, and here’s our take: it’s cool, but → continue…

Tech Insights teardown confirms Galaxy S9 uses Samsung and Sony image sensors

The analysts at Tech Insights have torn down the Samsung Galaxy S9 in order to analyze the device’s camera sensors and, as usual, the summary of their findings makes interesting reading for anyone who has an interest in image sensor technology. The main takeaway from Tech Insight’s report is that Samsung is once again using different image sensors by region.

Depending on where you buy the Galaxy S9, your device will either come with a Samsung S5K2L3 or Sony IMX345 chip.

Both imagers use a 3-layer stacked structure, comprising a CMOS image sensor, image signal processor (ISP) and DRAM. The Sony IMX345 is very similar in structure to the IMX400, the world’s first 3-layer stacked imager that was introduced on the Sony Xperia XZ flagship a year ago.

The Samsung S5K2L3 ISOCELL Fast sensor is the Korean manufacturer’s first 3-layer stacked model. In contrast to Sony’s custom solution with the DRAM in the middle, Samsung has opted for connecting the DRAM chip face-to-back on the ISP. The assembly also includes a dummy silicon structure filling the unoccupied space next to the DRAM chip.

This definitely won’t translate into noticeable performance or image quality differences between Galaxy S9 smartphones, but it does seem to show that Samsung is far from its goal of dethroning Sony to become #1 in the global image sensor market—it’s hard to dethrone the competition when you’re still using their sensors.

    Samsung explains the sensor tech behind the Galaxy S9’s super-slow-motion mode

    Samsung published a couple of technical blog posts today, providing some detail on the stacked sensor technology used in the new Galaxy S9 and S9 Plus smartphones, and specifically how this tech is used to power the devices’ super-slow-motion mode.

    This mode can record 960 frames per second at HD resolution for a duration of 0.2 seconds, which translates into 6 seconds playback time at 30 fps—32 times slower than standard video. The resulting videos can be reversed, exported as GIFs and edited in other ways.

    To achieve the blistering fast frame rates, Samsung has adopted similar imaging technology to what we’ve previously seen on some Sony devices. The S9 sensor offers faster sensor readout-times, bandwidth and video processing of the application sensor than on previous Galaxy generations by using a three-layer stacked sensor design that consists of the CMOS image sensor itself, a 4x faster readout circuit, and a dedicated DRAM memory chip for buffering:

    In addition to slow-motion, the stacked sensor helps reduce rolling shutter effects in video mode, and counter camera shake through frame-stacking methodologies.

    “We were able to achieve a readout speed that is four times faster than conventional cameras thanks to a three-layer stacked image sensor that includes the CMOS image sensor itself, a fast readout circuit, and a dedicated dynamic random-access (DRAM) memory chip, which previously was not added to image sensors,” explained Dongsoo Kim. “Integrating DRAM allowed us to overcome obstacles such as speed limits between the sensor and application processor (AP) in a high-speed camera with 960fps features.”

    Canon shows off full-frame sensor that shoots 100fps Full HD in ‘exceptionally low-light’

    At CES 2018, Canon unveiled three specialized CMOS sensors: an ultra-high resolution 120MP APS-H sensor, a 5MP Global Shutter sensor, and a 19μm Full HD sensor capable of shooting 100fps Full HD in extremely low light. Each does something special—offering high resolution, global shutter, and high-sensitivity, respectively—and now, a few months later, Canon is showing off these sensors in a series of demo videos.

    The first video featured the 120MXS sensor, which can shoot a mind-boggling 9.4fps at 120MP resolution. Now Canon USA has released the second video in the series, demoing its full-frame 19μm Full HD sensor made for shooting slow motion in extremely low light:

    The 35MMFHDXS CMOS sensor, capable of shooting 100fps Full HD in ‘exceptionally low-light environments.’

    The sensor is called the 35MMFHDXS, and in many ways it’s the polar opposite of the 120MXS. It only contains 2.2 effective megapixels, but each of those pixels is a whopping 19μm x 19μm in size, allowing them to capture a lot of light. This, combined with new pixel and readout circuitry that helps reduce noise, is what allows this full-frame sensor to capture Full HD at 100fps even when shooting in very little light.

    You can see what this means in the video up top, or read Canon’s own description of the 19μm Full HD sensor below:

    The 35MMFHDXS CMOS sensor delivers high-sensitivity, low-noise imaging performance, enabling the capture of Full HD video even in exceptionally low-light environments. The sensor’s pixels and readout circuitry employ new technologies that reduce noise, which tends to increase as pixel size increases. High sensitivity and increased well depth have been achieved through a larger pixel size of 19μm x 19μm (square) with proprietary device design technologies. The 35MMFHDXS CMOS sensor is available in RGB, → continue…
