So I was unconvinced of my mobile phone’s claims to have a proper VGA resolution camera. I suspected that the photos taken at the highest resolution were of no better quality than the ones taken at the lowest resolution, and then just scaled up using a rudimentary resize algorithm. I had to know.
I was assisted in my project by Butter Rabbit, as you will see. I started by taking photos of Butter Rabbit at the three available resolutions: 160×120, 320×240 and 640×480.
I then enlarged all these three images up to the same size, namely 1280×960. If my hypothesis was correct, these three images would be practically indistinguishable from one another.
Finally, so that I would be able to present my findings to you, I cropped these images down to the same 300×200 detail. Here they are:
LOW
MEDIUM
HIGH
As you can see, my paranoia was unfounded. Thank goodness for that.
