Why don't digital SLR cameras use three sensors like those 3CCD video cameras? - prism digital portable tv customer service
BACKGROUND some image sensors - http://www.cambridgeincolour.com/tutorials/camera-sensors.htm
and sensors can be only one color on each light-sensitive - and the Foveon sensor photo sites on top of each - why not 3-sensors are arranged around a glass prism, like Panasonic and Sony with a sound sensor 3-CCD video camera?
Increase the quality and megapixel digital SLR camera to a large extent ...

Your instructions do not apply to 3-CCD sensors, which require that the light is split by the prism system. Because they do not explain your question is missing some data, such as the fact that these systems with sensors, video cameras are very low.
Therefore, making a DSLR camera with such a system has increased the cost and complexity. In addition, that the argument that the quality and increased megapixels is not supported by history. Tested Minolta SLR lens, called RD-3000 and was a failure. Sensors based Bayer is better and the cameras are not as thick.
If you are seeing a 3-CCD: 1) sensors physically much smaller than an SLR and 2), cameras are often physically bigger than a SLR. Thus, a 3-CCD SLR is a camera should be on the lookout for a huge 3-CCD prism on.
Therefore, Nikon, Fujifilm, and others discuss the sensors that go on Bayer, but better than the Foveon sensor.
And then a 3-CCD is notIndeed, contrary to what you say, not really a practical way to increase the quality and megapixels for a digital SLR camera.
I can for several reasons.
1. Price. Sensors Digital aa much larger and more expensive than the sensor of the camera. The consumption on the video camera has 740x480 resolution. It is 0.3 megapixels. These sensors are relatively inexpensive to put three in a camera and still in the affordable range. Try to get a camera with sensors 3 x 12 megapixels, and probably double the price.
2. Sensitivity. Foveon or not getting to the fire to three sensors, we have divided into three parts. If you divide the first flow has been divided into two sub-streams or 3-way split - at least in its sensors (a) is of them at most 1 / 3 of the light to play. This means that 1.5 stops victims of sensitivity ... Not good.
3. Quality - The quality of modern cameras, Bayer is so good, it is difficult to imagine why someone is willing to be two questions from a sensor camera 3 above answer, and exactly how to improve the quality. I think it will not improve in proportion to rising prices and there, with lots of lighLoss of t. Vision, there are also even more, not available or too expensive and cumbersome for video. It is therefore important to view the video colors correctly received by the sensor (s) as may be subsequently revised in the world of photography!
