Sony researchers in Tokyo reveal a digital SLR part that’s actually drool-worthy: a CMOS sensor the size of 35mm film that registers 24.81 effectual megapixels—close to 26 million totals. It’s also built for speed with an all-pixel scan time of 6 frames per second, in 12-bit color. Sony isn’t about to pop it in one of its Alpha models, at least not as far as we can tell. In fact, Nikon would be a more probable customer for this easy target when it ships this summer, the improved to vie with Canon’s $8,000 EOS-1Ds Mark III DSLR, which has its own 21.1-megapixel full-frame CMOS. (Those pro guys really like it when their sensors are the same size as the film they used to use.) Now, who ever said the megapixel race was over? Sony Develops 35mm full size CMOS Image Sensor with 24.81 Effective Mega pixel declaration and extremely high signal conversion pace for use in Digital SLR Cameras

Tokyo, Japan - Sony company today proclaim the development of a 35mm full size (diagonal:43.3mm/Type 2.7) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the rising requirement for rapid image capture and superior picture quality within digital SLR cameras.

Development background

In new years, the demand for digital SLR cameras featuring high resolution and wide graduation ranges able of capturing every detail of the subject matter has continued to increase, particularly among high-end part-time user. as well, the increasing user requirement to shoot from the same focal length and angle as 35mm film cameras using interchangeable lenses has led to significant interest in the development of 35mm, full size CMOS image sensors.

However, there are a number of technical challenges to developing full (large) size image sensors, such as the propagation delay caused by using extended power circuitry and signal lines, and the difficulty of maintaining uniform sensitivity and signal diffusion across the surface of the screen.

also, because current semiconductor exposure systems are unable to cover the entire chip surface of 35mm full size CMOS image sensors, multiple experience are required. This results in the difficulty of accurately controlling exposure variance and matching circuit patterns.

Benefits of this device

The newly developed CMOS image sensor combines unique circuit design technology with Sony’s advanced manufacture expertise, including a system of joining multiple exposed patterns together and advanced planarization for minimizing fluctuation, to realize 35mm, full size, 24.81 effective megapixel resolution. Sony’s “Column-Parallel A/D Conversion Technique” also provides each column within the sensor with its own A/D converter, minimizing image squalor caused by the noise that arises during analog meting out while at the same time delivering an enormously high signal change speed.

The enhanced image quality make by the sensor’s 24.81 effective megapixel resolution, wide range of commencement air achieved by its full size broad dynamic range, and the low noise, high resolution, ultra-responsive recital give by Sony’s Column-Parallel A/D exchange technique enable it to meet the ever-increasing requirements within high performance digital SLR cameras.

Sony will target for mass manufacture of this CMOS image sensor within this year.

Canon lunched EOS Rebel XSi digital SLR camera put back Canon’s current entry-level D-SLR, the XTi. The new camera includes many ‘pro’ features previously only obtainable in the much higher-end series. EOS Rebel XSi camera boasts an improved autofocus sensor, enhanced 14-bit A/D conversion, an higher Live View function, and the proprietary DIGIC III image processor. Rebel XSi has a larger, 3-inch LCD monitor, improved from the 2.5-inch screen on the Digital Rebel XTi model. The larger 230,000 pixel screen features a make wider color gamut, seven brilliance settings for easy viewing under a variety of shooting conditions and a wide viewing point of view in all directions.

The EOS Rebel XSi camera features a substantial yet streamlined profile, with curved edges, contoured surfaces, handily placed controls and comfortably constructed rubber grip and thumb rest that all contribute to fatigue-reducing hand fit. The camera body is constructed of a rugged yet lightweight mixture of stainless steel and polycarbonate fixed with glass fiber. The frame outside is enrobed in a durable ABS and Polycarbonate resin and offered in a choice of silver or black finishes. At the heart of the new EOS Rebel XSi is its newly designed 12.2 megapixel APS-C size Canon CMOS sensor. This new sensor employs big micro lenses over each pixel to reduce noise and improve understanding up to ISO 1600, which is ideal for high-quality images in low light.

The Canon EOS Rebel XSi DSLR also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first set up in 2007 with the EOS-1D Mark III Professional Digital SLR and now available for the first time in an entry level Canon digital SLR camera. Additionally, the new camera is ready by means of Canon’s Auto Lighting Optimizer technology, which corrects image brightness and distinction automatically. Introduced most recent year in the EOS 40D cameras, this valuable optional feature now works in all exposure modes and utilizes Face discovery technology to prevent underexposure with backlit faces. The EOS Rebel XSi is the first model in the Rebel series to incorporate DIGIC III. The DIGIC III technology ensures that the fine details and natural colors of the images are optimally recorded. The DIGIC III processor also manages the camera’s efficient energy consumption and high-speed signal processing presentation.

Introduced in 2007 on the EOS-1D Mark III DSLR, the Live View function makes its debut in an entry level Canon DSLR with the EOS Rebel XSi camera. Live View allows users to frame shots through the LCD screen rather than the viewfinder. Going beyond the manual focus and phase-detection AF capabilities of former EOS models with Live View, the EOS Rebel XSi camera adds a new “Live Mode” contrast-detection AF function that allows the camera to heart without thinking during Live View without lowering the response mirror. The EOS insurgent XSi is also the fastest firing Rebel model to date, capable of endlessly capturing 3.5 frames per second for bursts of up to 45 images in large/in good health JPEG mode and 6 frames in RAW mode.

The new Rebel XSi DSLR utilizes Canon’s EOS Integrated Cleaning system, first introduced on the EOS Rebel XTi camera. The camera’s Self-Cleaning Sensor Unit shakes dust particles off of the low-pass filter in front of the sensor. The dust is after that trapped by an glue along the base, preventing it from causing more nuisance. Cleaning is engaged each time the camera is powered up or shut down or manually through the “clean now” function.

The new EOS Rebel XSi camera utilizes SD and SDHC memory cards including those with capacities higher than 2GB, making it the perfect upgrade for users already equipped with SD cards from point-and-shoot model cameras. in addition, the EOS Rebel XSi camera utilizes Canon’s new high-capacity LP-E5 lithium ion battery pack, which provides 50% more exposures per charge than earlier models with virtually no increase in size or weight.

Expected to ship in April 2008 the Canon Rebel XSi camera is available in body-only configuration which includes a rechargeable battery pack and charger, USB and video cables, a neckstrap, an EOS Solutions Disk CD, plus a 1-year Canon U.S.A., Inc. limited warranty. The new camera will also be available in a lens kit version which take in everything in the body-only kit plus the EF-S18-55mm f/3.5-5.6 IS zoom lens. The two versions carry estimated retail prices of $799.99 and $899.99, respectively.
