Future broadcast cameras could see less distortion with 8K global shutter tech

As camera sensors gain more detail, the high resolution they deliver makes another issue a bit more obvious. The high resolution reveals that traditional rolling shutters create distortion in the fastest subjects. But a new sensor developed by Cmosis, the same company powering the Lecia M, could solve that issue with a new 48-megapixel sensor with a global shutter.

Designed for professional broadcast camcorders, the CMV50000 shoots in 8K (7,920 x 6,004) at 30fps, yet also uses a global shutter design. The company says the sensor is an industry first, with twice the resolution of previous global shutter options.

Traditional camera shutters scan across the image, which means the top of the frame isn’t exposed at the exact same time as the bottom of the frame. Since each image isn’t exposed at the same time, footage of objects moving faster than that rolling shutter tends to appear distorted.

Global shutters, on the other hand, expose the entire sensor all at once, eliminating that distortion since the top of the image is recorded at the exact same time as the bottom of the image.

The sensor measures just larger than a full frame sensor, though smaller than the medium format options, at 36.43 x 27.62mm. While the camera is capable of 8K resolution, users can also bump up the speed and shoot at 4K at 60fps. The sensor also includes an high dynamic range mode.

The sensor is being first released in monochrome, with a color option expected before the end of the year. Designed for high-end cameras, the sensor alone will cost camera manufacturers about $3,800 to include inside their tech. The company says the primary use for the sensor is broadcast and video cameras, though the sensor could also power machine vision in manufacturing as well as security and 3D imaging applications.

Cmosis, now nearly 10 years old, specializes in CMOS sensors for photography and for industrial, medical and scientific applications.

Canon EOS R5 will be a video beast, with 8K RAW, 4K at 120 fps
canon eos r5 video details 8k raw 4k 120p april 2020 update 2

Canon has released yet another tease of its upcoming EOS R5, revealing new details about the mirrorless camera's video specifications. The new information largely confirms rumors that have been circulating for weeks and proves that the R5, the presumed new flagship of Canon's mirrorless line, will be a formidable force for filmmaking.

While 8K had previously been announced, resolution alone is rarely the determinant of image quality, especially as we push beyond 4K. We now know more specifics about exactly how the camera will process video, and it isn't just for those 33 million or so pixels that R5 will excel. It shoots 8K at 30 frames per second in either RAW or 10-bit 4:2:2 in the H.265 format with either Canon Log or HDR PQ color profiles. It does this internally, without requiring an external SSD or HDMI recorder, and without cropping the sensor.
