Here’s a cross section view of the consumer light field camera unveiled by Lytro yesterday. Many people have been wondering about the camera’s output resolution. The official specs are enigmatic in this regard, as the resolution isn’t listed in megapixels (it boasts “11 Megarays”). If the diagram is to scale, however, we can learn a little about the sensor’s size. The camera is listed as being 41mm tall, so the sensor appears to be between 7.5×7.5mm and 10.5×10.5mm — roughly the size of a Fujifilm X10 sensor.
Update: Photographer Jim Goldstein did his own calculations can guesses that the photos are equivalent to 1-2 megapixels.
