Tvtechnology: What’s New In Large Format Sensor Cameras

Hoya Announces Second Quarter Financial Results – Yahoo Finance

The Cion bucks the latest trend toward dSLR and boxy cameras by adopting a design reminiscent of an ENG camera. The Cion uses popular PL-mount lenses. Since entering the cine camera market three years ago, Canon USA has pursued the large-sensor market on two fronts. Canon EOS 300 Were obviously working with very large-frame sensors, 36x24mm sensors that we use in our DSLRs, said Canon national marketing executive Larry Thorpe. And with every generation that we come out with, and they come out with some frequency with that domain of the DSLR, were always working on noise and dynamic range. Those are the two challenges, especially when you increase the pixel count, because once your photo-site goes down in size, youre confronted with the challenges of noise and dynamic range. Then separately, since we entered the cinematography world with the Cinema EOS systems, we have major efforts going, continuing to develop sensors there, Thorpe said. Both Panasonic and Sony have made waves with low-cost 4K cameras that push the price of 4K production down to that of HD dSLR cameras. Sonys A7s uses a full-frame 35mm sensor, sells for well under $ 2,000 and accepts a variety of lenses. It requires an outboard recorder to create 4K video files, but a fully outfitted kit can be had for less than $ 5,000. If thats too rich for you, then Sony has the FDR-AX1 Handicam that makes 4K with a 1/2.3-inch 8.3-megapixel Exmor R CMOS image sensor. Another offering in Sonys line is the FDR-AX100/B, which uses a 4K 1-inch Exmor R CMOS sensor with direct pixel readout and has a cost of just $ 2,000and that includes a fixed 12x zoom lens. Panasonic GH4 camera body with micro four-thirds sensor Panasonic got a lot of attention with the release of its Lumix DMC-GH4 camera, which is equally at home shooting stills or video. For less than $ 2,500 equipped with a good lens, the GH4 can shoot 4K video using a micro-4/3s sensor and record it on an SD memory card. If you want to work at HD quality, the GH4 can record 1080p at frame rates up to 96 fps for smooth slow-motion effects. If thats too much to spend, Panasonic recently released the Lumix FZ1000 that has many of the same specs as the GH4, but with a fixed 16x zoom lens and a reduced feature set. The price is just $ 900, which puts it into risky point-of-view camera range where you might be willing to sacrifice the camera to get the shot. Grass Valley made the decision to avoid large-format single-sensor design cameras in order to concentrate on the 4K live broadcast market with three-sensor 2/3-inch cameras. Grass Valleys senior product marketing manager for cameras, Klaus Weber, pointed out its a matter of picking the right tool for the job. The Super 35 single sensor design is a compromise, but a good compromise for film-style shooting where you want a shallow depth of field. But for live action, you dont want to be limited to your in-focus subjects limited to a few centimeters, and everything in front of or behind that out of focus. Grass Valley LDX He said that in developing the design for the three 2/3-inch sensor in its LDK camera line, it was important to maintain the largest pixel size that was practical. If you look at sensors for high-def cameras, it all starts with pixel size, Weber said. They all have a pixel size or pixel pitch of 5 to 6 micrometers, and theres a good reason because its the best technology and the best compromise between sensitivity, dynamic range, and what you need for good performance in a reasonably small size. The camera provides two million pixels each for the red, green and blue CMOS chips. Another camera maker that showed a 2/3-inch 4K camera at the recent IBC was Hitachi Kokusai with its SK-UHD4000 Ultra HD. Since camera makers use the green channel to generate the sharpness and luminance of a cameras output, Hitachi added a fourth sensor to its system, allotting two of the sensors for green pixels. This boosts the amount of pixels overall. The camera comes equipped with tried-and-true functions and features specifically designed for TV program production in the studio and in the field, said company vice president for sales and chief operating officer Sean Moran in the products announcement. Like Grass Valley, Hitachi emphasized the advantages of being able to use 2/3-inch form-factor lenses including long zooms for live sports and event production. When it looked to get into the large sensor camera market, Ikegami chose to partner with a venerable company with deep roots in the film industry, ARRI, which had already developed a large-format sensor system. The result was the HDK-97ARRI Super 35mm Format Camera.

During the quarter, revenues totaled 121,242 million yen, increasing by 18.6% from the same period the previous year. Pre-tax profit for the quarter was 34,256 million yen, while profit for this quarter was 27,323 million yen, both of which marked gains of 114.5% and 113.9%, respectively. Profit attributable to owners of the company stood at 27,150 million yen, an increase of 113.3% compared to the same quarter in the previous year. During the quarter, sales of products for smartphones and tablet PCs as well as sales of glass disks for HDDs performed well in the Information Technology segment, but sales of digital camera related products continued to perform weakly. Meanwhile in the Life Care segment, we significantly increased sales in the eyeglass lens business in overseas markets and through inclusion of Seiko Optical Products, a sales company of SEIKO eye wear, as a consolidated subsidiary. The retail contact lens business in Japan experienced last-minute demand up until March and a downward reversal beginning in April due to the April 1 hike in the consumption tax rate, thus resulting a year-on-year drop in earnings. The endoscope business performed robustly primarily in Asia. For the six months ended September 30, 2014, revenues totaled 234,314 million yen, and pre-tax profit was 56,700 million yen, both of which increased 15.6% and 57.1% respectively. Profit for the term increased 80.4% to 45,285 million yen, and profit attributable to owners of the company was up 79.6% to 44,948 million yen compared to the same quarter in the previous year. “The profit for this quarter exceeded our expectation due primarily to solid result of the Information Technology segment, said Hiroshi Suzuki, chief executive officer of HOYA. We see that this trend will persist for a while. This quarter our measures of swift restructuring in the Information Technology segment bore fruit, commented Eiichiro Ikeda, chief operating officer, Information Technology. We will drive growth in areas where there are opportunities amid overall shrinking markets. HOYA also announced the interim dividends of 30 yen per share of common stock.
