The New iPhone’s Camera: Sensor Size and Pixel Count
The just announced Apple iPhone 4 has a new 5 MPix camera. Now, 5 MPix cameras are not uncommon but Apple did not do what most other manufacturers do. They did not just stuff more pixels into the same sensor size. No, Steve Jobs even took the time in his iPhone 4 presentation keynote (00:51h) to explain the fact that if there are more pixels on the same sensor size, this means a smaller sensor area per pixel, and that means each pixel can capture less light (less photons).
The website 6mpixel.org explains this phenomenon.
So Apple did not only increase the pixel count but also increased the sensor size to keep the sensor area per pixel the same. This is just one of the reasons why I love Apple products.
