Canon introduces global shutter CMOS sensor with improved dynamic range

by on Aug.31, 2016, under Reviews

Canon has announced a global shutter CMOS sensor with a re-designed pixel structure aimed at boosting dynamic range. Using global shutter presents a clear benefit for the sensor’s videography applications, as it doesn’t suffer from the distortion effects that a standard ‘progressive scan’ sensor does when capturing fast-moving subjects.

However, global shutter designs have tended to offer less dynamic range than their conventional counterparts. Canon says that the sensor’s drive system (the way it’s read out) increases the amount of light the sensor can capture before overexposing. This is combined with a more efficient pixel structure and ‘optimized internal configuration’ to reduce noise and increase sensitivity. The result should be improved dynamic range, though it’s not clear how this improved performance will compare with traditional chips of the kind that exhibit rolling shutter.

Canon says it will explore use of the chip in measurement and industrial applications, and consider applications in video production. No details of the sensor’s size or resolution were given.

Press release:

Canon develops global shutter-equipped CMOS sensor that achieves expanded dynamic range through new drive method

TOKYO, August 31, 2016—Canon Inc. today announced that it has developed a new CMOS sensor equipped with a global shutter function that, because it exposes all of the sensor’s pixels at the same time, enables the capture of distortion-free images even when shooting fast-moving objects. Employing a new signal-readout drive system and new pixel structure that significantly expands the full well capacity and reduces noise, the sensor contributes to high-image-quality video capture by making possible the realization of a wide dynamic range.

Distortion-free image capture when shooting fast-moving objects

Standard CMOS sensors make use of the rolling shutter method, which sequentially exposes the pixels one row at a time. Because rolling shutters can create slight discrepancies in signal-readout timing depending on the location of the pixel, images of fast-moving objects may appear distorted and flash photography may result in the occurrence of the flash band phenomenon, in which the upper and lower portions of images display different levels of brightness. Because Canon’s newly developed CMOS sensor employs a global shutter, when shooting such fast-moving objects as a rotating propeller or a speeding train, subjects are able to retain their proper form to create distortion-free images. Enabling the confirmation of object shapes with a high degree of accuracy, the sensor offers potential benefits in industrial applications, including as a sensor for use in inspection cameras.

Wide dynamic range realized through new proprietary drive method and pixel structure

When the newly developed CMOS sensor converts light into electrical signals and stores the signal charge in memory, the new drive system achieves a significant expansion in full well capacity. Also, because it employs a structure that efficiently captures light and each pixel incorporates an optimized internal configuration, the sensor makes possible increased sensitivity with reduced noise. The expanded full well capacity, realized through the sensor’s new drive system, and substantial reduction in noise, enabled by the new pixel structure, combine to deliver a wide dynamic range, facilitating the capture of high-image-quality, high-definition footage even when shooting scenes containing large variances in brightness.

Canon will explore various industrial and measurement applications for the newly developed CMOS sensor and consider deploying it in the field of video production for cinema production applications, TV dramas, commercials and more.

Peak Design adds Range Pouch to Everyday lineup

by on Aug.31, 2016, under Reviews

Peak Design has added the Range Pouch to its lineup of versatile Everyday camera bags. The pouch is designed to carry a lens on a belt, in a bag or on a strap, and is available in three sizes. The smallest is designed for kit and prime lenses, and the large will fit up to a 70-200mm. The pouches pack down flat when not carrying a lens, and the larger models can be configured to fit a couple of smaller lenses stacked on top of each other.

Right now the Range Pouch is available as an add-on when you back Peak Design’s current Kickstarter campaign. The small Range Pouch can be added for $29, the medium for $34 and the large for $39. Following the campaign, the small will cost $35, the medium $40 and the large $45.

Garmin VIRB Ultra 30 4K action cam unveiled with voice control

by on Aug.31, 2016, under Reviews

Garmin has introduced the VIRB Ultra 30, a rugged action camera capable of recording 4K/30fps footage. Despite its small size, Garmin packs a bunch of sensors and features into the camera, including GPS, voice control to start recording, a touchscreen display and a high-sensitivity microphone. The VIRB offers what Garmin calls 3-axis image stabilization, but it’s available up to 1440/60p, which leads us to believe it’s digital.

In addition to 4K footage, the new VIRB action camera can record 720p/240fps slow motion video and can capture 12 megapixel still images. Content is stored on a microSD card. The touchscreen display works when the camera is enclosed in its waterproof case, as does the microphone, according to Garmin. That waterproof case includes an anti-glare coated and water-repellant lens.

In addition to changing settings via the touchscreen display, the VIRB Ultra 30 supports Sensory TrulyHandsfree voice control. Commands like ‘OK Garmin, remember that’ for tagging moments and ‘OK Garmin, start recording’ are supported. Additionally, the camera can be controlled remotely using the VIRB app on a tablet or smartphone. The VIRB app is complemented by the Garmin VIRB Edit desktop software for post-processing.

The Garmin VIRB Ultra 30 is available in the U.S. now for $499, and will be available in the UK for £449 in Q3 2016.
