CMOS rolling-shutter effects
Further, Zoran is claiming that its new digital camera SoC offers “the industry first CMOS rolling-shutter correction.”
The DSC market will become an even more cutthroat in 2011, with some camera manufacturers fighting literally for survival.
If consumer can be depended on to keep trading up for increasingly better photos, there is opportunity in high quality. Can such a trend be a good business for DSC SoC vendors like Zoran? “Yes,” said Pertsel. “It opens up a whole new [SLR] market for us.”
a U.S. chip supplier Ambarella, sucked 3D digital camera function as growth opportunities; The company released in November, a 3D video pre-processor (pre-processor) chip S3D, can be used with the camera SoC products, so that end digital camera can support specification of 3D Full HD 1080p video recording and high-resolution 3D still photography.
In 2010, the digital camera has video capabilities overwhelmingly support – or at least can provide a static screen shot and video mixing capabilities; In fact, the chip industry senior marketing director Zoran Senya Pertsel that the current market have been on offer one hundred percent digital camera video recording function, but different brands of digital cameras, video quality and performance is also very different.
1. support Full HD video capture (which is very common in 2010);
The market research firm predicts shipments of hybrid cameras to grow from “8.3 million units in 2009-representing about 7.6 percent of total camera units shipped-to 120 million units in 2014-accounting for about 89 percent of total cameras shipped. “With hybrid camera models already available from Eastman Kodak, Canon, Nikon, Samsung and Sony, etc., iSuppli said that” hybrid cameras at the $ 150 – $ 200 price point represent the next big growth opportunity in the industry. “
Five things to watch for in the new DSCs next year are:
iSuppli estimates that shipments of hybrid camera, will be 8.3 million units in 2009 (overall camera market shipments accounted for about 7.6%) in 2014 reached 120 million units (proportion of total camera shipments 89%); currently include Eastman Kodak, Canon, Nikon, Samsung Sony already has with such products. And the agency also believes that the price at between $ 150 to 200 hybrid camera market will be the new wave of growth opportunities.
4. Compact camera body with abilities to switch lenses (offering Single Lens Reflex camera-like performance)
you might just received for Christmas when the latest and most unusual of a digital camera (DSC) gift … I do not want to feel disappointed, but in the next 6 to 12 month period (a typical consumer electronics product life cycle), it is expected there will be a lot more advanced digital camera features new products to grab market cheaper prices.
3. to support a new generation of video coding specifications (stored in the memory card to make the image files smaller);
Meanwhile, Ambarella (Santa Clara, Calif.) is hanging its hat on 3-D as its growth opportunity in DSCs.
3-D cameras represent another area of ??growth for the camera sector, iSuppli agreed, but with a caveat. With 3-D games and video already being offered, “3 – D cameras will likely hit store shelves by the 2011-2012 time frame, “iSuppli said. But the firm added that” such cameras are not expected to become a mainstream technology until after the 3-D screens that are used to show 3-D pictures and video reach approximately 30 percent penetration. “
More importantly, as video shooting becomes a standard feature in point-and-shoot DSCs, digital video stabilization may be just the thing that differentiates one DSC from another.
More importantly, when the video recording feature has become a standard digital camera with a fool, it provides the stability of digital video, digital cameras has become a major key to differentiation.
Some research institutions have predicted that within a few years the digital camera market will be headed toward recession. For example, in a recent iSuppli report that, once the consumer electronics market 当红炸子鸡, but also stores the number one best-selling products fool the camera, in good condition with about three years after shipments began to decline; mainly because there are newer technologies and with camera phones are everywhere.
While Zoran SoC uses an H.264 video codec to capture images, it combines H.264 codec options, noise reduction methodologies and looks for similarities in video frames, in order to reduce the size of a video file by 40 percent , claimed Pertsel.
Zoran also think that 3D is the trend can not be stopped, the company upcoming COACH 14 digital camera with a dual-sensor SoC can support 3D moving / still image recording, and directly through the HDMI 1.4 interface to connect to 3D TV. However, Zoran intends to focus on the basic function of a digital camera, so that products can shoot better photos; Pertsel said: “a camera in a variety of harsh environmental conditions, the quality of the photo shoot, is the real skill of the to show. “
With the built-in camera phone image quality is getting better, iSuppli forecast is not surprising; while the digital camera manufacturers, the immediate priority is selecting a foothold, to find a opportunities for growth, and think of ways of expanding the definition of a new market boundaries.
Market research companies are already predicting the decline of the DSC market in just a few years. “The point-and-shoot digital still camera-once a red-hot consumer item and a best-selling retail mainstay-has about three good years left before its shipments begin to decline, supplanted by newer technologies and the omnipresent camera in cell phones, “stated iSuppli market researchers in their recent press release.
Shooting video in a dark environment is always problematic. Also, when taking a picture of a subject in shadow, for example, it no easy task to capture effectively both the shadowed elements and those in brighter light. That where “digital detection and correction” becomes critical, explained Pertsel.

digital cameras in 2011 will be actively promoted so-called Full HD video recording capabilities ; iSuppli predicted that the next hybrid camera – body in a single integrated HD video recording and still image capture function – will be more and more common, prices are approachable: “In particular, because the processor chip features more advanced, as well as flash memory prices. “
You might have just received the latest, dazzling digital camera as a holiday gift. I don want to spoil your fun, but predicting the” new, improved “- and much cheaper – version that almost certain to come down the pike in the next six to 12 months (a cycle of obsolescence that defines the consumer electronics business) is what this reporter is paid to do.
5 things to watch for in new cameras during 2011
Unlike CCD image sensors, designed to use a “global shutter” in which the entire frame is exposed for the same time window, CMOS sensors – used in most DSCs today – deploy an image acquisition method called “a rolling shutter.” A CMOS image sensor records each frame by scanning across the frame, or “rolling” through the frame, exposing different portions of the frame at different points in time. This method produces some predictable distortions, often known as “rolling-shutter effects.” They include images bending diagonally in one direction or another (skew); wobbly images (often known as the jell-o effect); and partial exposure. Clearly, serious digital processing capabilities will be needed to combat such rolling-shutter problems in CMOS image sensor-based DSCs.
Traditionally, expensive DSCs or video camcorders are equipped with gyroscopes that compensate for the human frailty of camera movement. If the camera operator is shaky, a set of motors, combined with special optics inside the camera work to stabilize wobbly video images. But in most DSCs, it too costly to integrate special optics and such a mechanical solution. Zoran is banking on its new COACH 14 SoC ability to do digital motion analysis, thus eliminating the gyroscope and special optics.

As video becomes a more prevalent feature in DSCs, the potential length of a video file in the memory card in one DSC will become an issue. “It especially true with video recording in 3-D,” noted Zoran Pertsel. This is because 3-D requires two video streams – one for the left eye and another for the right, which means twice the storage space compared to a regular video file.
iSuppli agreed that 3D photography is the market will be another opportunity for growth opportunities, but there is but the book; the agency forecast, 3D camera time should be listed in the 2011 to 2012, but this type of camera in the 3D screen market penetration to reach 30% before, it could not become mainstream.
4. digital camera body smaller, and can transform lens (like a SLR like features);
1. Full HD video capture (already common in 2010)
For example, in shooting in the dark environment, has always been a problem; there is a shadow when shooting objects, it is not easy to effectively capture the object with light in the shadow boundaries; Pertsel explained that this is the number of detected (detection ) and correction (correction) technology is the key.
2. to support 3D video (3D in the end can not succeed yet to be determined, but it should not be avoided);
I recently obtained the views of experts from the digital camera, summarized in the following five digital cameras in 2011 market is worth noting that technical points:
But Zoran plans to emphasize more the DSCs classic and fundamental ability to take better photos.
5. in all conditions (eg light, dark, CMOS rolling shutter effect and so on … …) can be sold under the smooth, stable pictures.
Ambarella goal is not to exceed $ 200 birth cheap version of 3D digital camera, so that consumers can take their own 3D movies; the company Marketing and Business Development Vice President Chris Day said: “The use of 3D TV to see really praise. “
DSCs in 2010 have overwhelmingly gone video – or with a” hybrid “of still and video. In fact, 100 percent of DSCs sold today offer video shooting capabilities, according to Senya Pertsel, senior director of marketing at Zoran Corp. mobile division. But each DSC video recording capability, in quality and performance, substantially varies.
Taking better photos in all conditions
The biggest push DSC vendors are planning in 2011 is “Full HD” video recording. Hybrid cameras – integrating HD video recording and still-camera capability into a single device – will become more popular and affordable, according to iSuppli, “especially as advancements are made in silicon processing capability and as prices for flash storage decline. “
short digital camera market in 2011 the competition will become more intense, and some vendors will even face life and death.
“How well your camera can shoot quality photos in all adverse conditions is what separates the men from the boys,” said Zoran Pertsel.
2. 3-D video (the jury is still out but it may be inevitable)
5. Delivery of smooth, steady video under all conditions (ie bad lighting, CMOS rolling shutter effects)
2010 年 12 月 31 日
With the quality of cell phone cameras growing dramatically better, iSuppli prediction is not so surprising. But for now, DSC manufacturers job is still to pick a spot, find a growth opportunity, flesh it out and define it a new fault line.
Zoran also sees 3 – D cameras as inevitable. Zoran upcoming COACH 14 digital camera SoC will enable 3-D with dual sensor support, 3-D stills and video encoding capabilities, and direct connection to 3-D TV via HDMI 1.4.
The chip vendor last month (November, 2010) announced a new 3-D video pre-processor called S3D, designed to work with Ambarella camera SoCs, by pitching that the combination will enable full HD 1080p 3-D video recording and high-resolution 3-D photography. The goal is to enable a consumer-friendly 3-D digital video camera – priced at less than $ 200 – capable of shooting 3-D video “that looks really good on 3-D TV,” said Chris Day, vice president, marketing and business development at Ambarella.
Many camera OEMs are also counting on a broader adoption of digital SLR (DSLR) cameras to keep their business going. “Among DSLR cameras-used more by professional photographers in the past-falling prices will spur increased adoption of the device by consumers now able to make the upgrade, “observed iSuppli. Zoran Pertsel has gone a step further by predicting the emergence of a new DSLR product segment, where camera OEMs will use a compact camera body (instead of bulky ones used today in DSLRs) to allow consumers to use interchangeable camera lenses.
Recent conversations with digital camera experts offers helpful insight into what OEMs and chip vendors are jockeying to establish as the battleground for the digital still camera (DSC) market in 2011.
3. A new-generation video codec (enabling a substantially smaller file size in a memory card)
