This Image Sensor Makes It Virtually Impossible To Blow Highlights

Image Sensor

Researchers at the German Institut für Mikroelektronik Stuttgart have developed an image sensor that makes it almost impossible to blow highlights with.

What this image sensor does, is using “self resetting pixels“, i.e. pixels that don’t clip when they get saturated but instead starts over and counts the times it has started over. From the research paper’s abstract:

Conventional CMOS image sensors with a linear transfer characteristic only have a limited dynamic range (DR) of about 60–70 dB. To extend the dynamic range considerably, the already successfully demonstrated concept of a linear self-reset pixel was employed in this work. With the self-reset concept the limit of the maximum analyzable photo generated charge (Qmax) during the exposure time is extended to a multiple of the saturation charge of the photo diode (Qsat) by asynchronous self-resets of the photo diode. Additionally, the remaining charge at the end of the exposure time is evaluated to increase the resolution of the opto-electronic conversion. Thus we achieved pixels with a DR of more than 120 dB combined with an improved low light sensitivity using a pinned photodiode.

In other words: you don’t have to worry about your exposure in order to save highlights in your image. Instead, you can set the best exposure for your subject and safely snap knowing that no highlights will be blown out.

This image sensor is a prototype and likely far from going into production. Never the less, it’s a technological innovation that sooner or later will be featured on image sensors.

The full paper “Realization and opto-electronic Characterization of linear Self-Reset Pixel Cells for a high dynamic CMOS Image Sensor” by Stefan Hirsch, Markus Strobel, Wolfram Klingler, Jan Dirk Schulze Spüntrup, Zili Yu, and Joachim N. Burghartz, is available here.

Let’s hope it’s something Canon will research too.

Future Canon Cameras Might Have An Even Better Sensor Dust Removal Feature

Sensor Dust

Canon patent application EP3522515A1 discusses method and technology for an image sensor dust removal system. Canon already has one of the best dust removal systems in the industry, so it can only get better.

Excerpts from the patent literature:

An imaging device such as a digital camera for picking up and recording an image by converting an image signal into an electric signal receives an imaging light flux by means of the image pick up device, which may typically be a CCD (charge coupled device) or a CMOS (complementary metal oxide semiconductor) it comprises. Then, the photoelectric conversion signal output from the image pickup device is converted into image data, which image data is then recorded in a recording medium such as a memory card. In such an imaging device, a cover glass, an optical low pass filter, an infrared absorption filter and other parts are arranged in front (on the subject side) of the image pickup device to form an image pickup unit there.

In an imaging device of the above-described type, when foreign objects such as dusts adhere to any of the surfaces of the cover glass and the filters of the image pickup unit, those foreign objects block the incident light flux and are picked up as black spots in the recorded image. Particularly, in the case of a digital single-lens reflex camera, the dusts that are produced when the shutter, the quick return mirror and/or some other part arranged near the image pickup unit is mechanically driven to operate can adhere, if partly, to any of the surfaces of the cover glass and the filters. Additionally, when the lens is being replaced, foreign objects such as dusts can get into the inside of the camera main body by way of the opening of the lens mount and adhere to any of the surfaces of the cover glass and the filters. However, when each of the cover glass and the filters is equipped with a piezoelectric element and the piezoelectric element is made to operate as a vibrating plate that give rise to elastic vibrations (to be referred to as flexural vibrations hereinafter) in the thickness direction, it can be made to operate as a dust removal device for removing the dusts adhering to the surfaces thereof.

[…] in an aspect of the present invention, there is provided a vibration device comprising a vibrating member having at least n (n≥2) piezoelectric elements arranged on a vibrating plate, each of the piezoelectric elements being formed by using a lead-free piezoelectric material and electrodes, wherein, if the temperature that maximizes the piezoelectric constant of the piezoelectric material of each of the n piezoelectric elements is expressed as Tm (m being a natural number from 1 to n), at least two of T1 through Tn differ from each other.

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:

Canon Might Have a 63MP Full Frame Image Sensor On Their Agenda, Leaked Document Suggests

An apparently legit Canon document describing a full frame image sensor with a resolution of 63MP leaked over the web.

The 35MM63MXSCD named CMOS sensor has Dual Pixel AF, shoots around 5fps, and is made with a 300nm manufacturing process.

We expect Canon to announce a high resolution EOS R camera in Q4 2019. Could this be the sensor Canon will feature in their upcoming high resolution EOS R camera? Hard to say. It might be but it might also well be one of Canon’s super-specialised image sensors, maybe even a prototype that never went into production.

The sensor in the leaked document seems at first glance to be the sensor rumored for the high res EOS R model, although the latest rumor we got was talking about a 75MP sensor. We tend to believe this sensor has nothing to do with the upcoming high resolution EOS R camera.

More about Canon’s special purpose sensors can be learned here.
