20 Megapixel Camera Phone Chip Rediculousness from Broadcom

broadcomBroadcom is producing a chip capable of handling a 20 megapixel camera phone, the BCM2763 VideoCore IV.  Why?  To provide their customers with the ability to one-up the 12 and 14 megapixel camera phone offerings, as if they don’t have enough pixels.   While the 20MP numbers are the “ceiling” of this signal processor’s capability, that doesn’t make the concept of a 20MP camera phone any less outrageous.  The chip does have some actually desirable characteristics though, such as 40nm CMOS technology, 1080P H.264 encoding, and minimal power usage.   Press release follows.

Why More Megapixels Isn’t Always More Better

megapixel_raceGizmodo has written an excellent article on the folly of sacrificing low light performance for unnecessary resolution.    An insightful response that follows the article:

“I was trying to decide at one point between the D40(6.1 MP) and the D60 (10.2 MP) Nikon. Every single time I would ask someone on flickr for their opinion they would say get the D60! Extra megapixels! Because of cost, and seeing as paying more for a VR lens in the D60, decided to go with the D40. And 6 MP is COMPLETELY FINE. I get the most amazing night shots and the quality is fine. Everyone seems to fall for this “Megapixel Myth” and gets the D60, but when it comes down to it, seeing the night shots of my friends D60, wouldn’t trade the D40 in for the D60 even if I could do it for free.”

David Pogue on Big Sensors in Small Cameras

Once again David Pogue crusades for truth in Image Quality, remarking on the new crop of high quality devices with big sensors:

“The best overall predictor of image quality, though, is the size of the sensor inside. Big sensors absorb more light, so you get better color and sharper low-light images. Small sensors pack too many light-absorbing pixels into too little space, so heat builds up, creating digital “noise” (random speckles) in your photos.”

The Lie of Interpolation

Look at this ebay auction. Here the seller claims a Fifteen Megapixel camera, but if you read closer, the pixels are Interpolated. This means the image is just resized to be more (blurred) pixels. A gimmick that is a waste of memory and whose only purpose is to deceive consumers into believing that they’re buying a high Megapixel device. Read on to find the camera actually only has 5.0 Megapixel!

Megapixel Myth Launches web site 6/21/07

MegapixelMyth.com launched on June 21st 2007. This web site was created to inform and educate consumers of digital cameras about all the factors that affect image quality. Educated consumers that know that there is mre to a camera than its megapixels will put forces on the manufacturers that will enable new lens, sensor, and processing technologies to succeed. This will help improve the image quality of cameras big and small.

Beyond Megapixels: Picking a Compact Digital Camera

“the megapixel arms race has now gotten severely out of hand”

“buying a camera with more pixels these days often means just paying more for a noisier image that captures less detail than a similar counterpart with fewer megapixels”
