My camera has 41 megapixel sensor and it does splendid work. In camera technology the megapixel count does not matter itself, but how large is the sensor. And indeed this 41 Mpix sensor is the largest of its class and thus the performance is best of its class. Because the individual pixels cannot get any smaller, then the actual sensor must be made larger to fit 41 Mpix. Therefore we need 100 megapixel camera sensors, because they collect light from large area and as a bonus they leave a lot of room for zooming in good lighting conditions. Perhaps you did not realize that in digital photography, the megapixel counting is not about making higher quality raw pictures but it is left there for zooming and cropping purposes and for low light performance and for noise cancellation. What if you retrospectively want to zoom into small detail of the picture, e.g. to identify what was that bird that was captured in the background? However, why we must mimic eye? Why not just increase the color channels? Birds have four color channels. Why not use six or more color channels in digital cameras? —Jouni
