Canon developing 8K DSLR, pro 8K display, more

Canon is working on a Cinema EOS System 8K camera and 8K reference display that will support the production of next-gen 8K video content, along with a still-image single-lens reflex camera equipped with a CMOS sensor featuring approximately 120 million effective pixels.

In addition, Canon has developed an APS-H-size (approx. 29.2×20.2 mm) CMOS sensor incorporating approximately 250 million pixels (19,580 x 12,600 pixels).

The Cinema EOS System 8K camera, which is being developed, will be equipped with a Canon Super 35 mm-equivalent CMOS sensor that makes high-resolution 8,192×4,320 pixel (approximately 35.39 million effective pixels) imaging performance, at a frame rate up to 60fps with 13 stops of dynamic range and a wide color gamut. The camera features a compact body and an EF mount that offers compatibility with most of Canon’s interchangeable EF lens lineup.

Incorporating Canon image-processing technology, the ultra-high-resolution 8K reference display aims to achieve high brightness, high contrast (high dynamic range) and a wide color gamut. Additionally, with a pixel density exceeding 300 pixels per inch — a level approaching the limit of human — the display intends to make possible ultra-realistic imaging that can enable the reproduction of even subtle changes in light.

When installed in one of Canon’s prototype cameras, the newly developed sensor was reportedly able to capture images that enable the distinguishing of lettering on the side of an airplane flying at a distance of approximately 11 miles (18 km) from the shooting location. The new CMOS sensor achieves a signal readout speed of 1.25 billion pixels per second, made possible through advancements such as circuit miniaturization and enhanced signal-processing technology. The sensor enables the capture of ultra-high-pixel-count video at a speed of up to five frames per second.

The company is also developing a still camera featuring a resolution of approximately 120 effective megapixels. The SLR camera will incorporate a Canon-developed high-pixel-density CMOS sensor within the current EOS camera series platform.  This will allow compatibility with most of the company’s interchangeable EF lens lineup. The camera will be capable of producing a three-dimensional texture, feel and presence of subjects. It will also provide resolutions more than sufficient for large-format printing and extensive cropping, while maintaining high image quality.

JVC offers new 4KCAM line of camcorders

During NAB 2015, JVC Professional introduced the new 4KCAM line of professional camcorders. The new product line contains three models — the GY-LS300 Super 35 mm camcorder, GY-HM200 streaming camcorder and GY-HM170 compact camcorder — all employing the newest advancements in 4K imaging and efficient encoding to accommodate a variety of workflows.

The JVC GY-LS300 (our main image) is designed for cinematographers, documentarians and broadcast production departments. It features JVC’s 4K Super 35 CMOS sensor and an industry-standard Micro Four Thirds (MFT) lens mount. JVC’s Variable Scan Mapping technology electronically adapts the active area of the Super 35 sensor to provide native support of PL- and EF-mount lenses, among many others. As a result, the GY-LS300 camera provides many lens options when used with third-party lens adapters.

Both the GY-LS300 and GY-HM200 include a built-in HD streaming engine with Wi-Fi and 4G LTE connectivity that allows live HD transmission directly to hardware decoders, the Wowza Streaming Engine and the ProHD Broadcaster server powered by Zixi. The camcorders support various streaming protocols in order to stream directly to websites and content delivery networks.

The GY-HM200 and the GY-LS300 also include dual XLR audio inputs that are mic/line switchable, with built-in phantom power, an integrated handle with hot shoe and dedicated microphone mount, and SDI and HDMI video outputs.

JVC’s most affordable streaming camcorder, the GY-HM200, is built for corporate video and ENG apps. It features a 1/2.3-inch BSI CMOS chip and built-in 12x zoom lens (24x dynamic zoom in HD mode) with optical image stabilizer. It delivers 4K Ultra HD, 4:2:2 full HD (50 Mbps) and SD imagery.

The GY-HM170 features a heavy-duty body with comprehensive video profile settings and controls for professional use. It records 4K Ultra HD as H.264 files and can record HD and SD footage in a variety of resolutions and frame rates. Other features include an integrated 12x optical zoom lens with two ND filters, built-in stereo microphone and 3.5 mm audio input and live 4K UHD output through a built-in HDMI connector.

4KCAM cameras feature dual SDHC/SDXC card slots for dual, back-up, and continuous recording. The camcorders also include a 3.5-inch LCD display and 1.56 megapixel color viewfinder (both with smart focus assist functions) and offer two-channel audio recording.

All three camcorders are now shipping.
