It's 10 megapixels, with a 5x optical zoom on probably a cut-rate lens, image stabilization (good for a small thing like that), and a wealth of "entertaining and versatile functions".
When a single lens images a distant white-light point source, such as a star, the image is slightly distorted because of dispersion in the lens; this effect is called chromatic aberration.
If you want to make unity out of the city's architecture, you must get in the car and zigzag around town, turning the windshield this way and that, as if it were a lens, piling image next to image like a David Hockney photomontage.
With high-end features like a 7X zoom lens, image stabilizer and the ability to zoom while shooting movies, you'd think that this camera would get the highest marks.
A red reflex lens image was taken when each participant was having retinal photographs.
A beam splitting mirror and a convex lens images the forward scattered light of the bead in the optical trap onto a 10×10 mm quadrant photodiode (S 5107, Hamamatsu, Herrsching am Ammersee, Germany) for the electrical position detection.
"It's got a wide-angle Leica lens, image stabilization, 720p HD video recording, and a 4x zoom.
This and other innate imperfections in a lens's image of a single object point are known as aberrations.
Imagine all the amazing medical applications and terrible art that would result from the ability to use your own skin as a lens to image what lies underneath. .
Bead displacements were detected by back focal plane interferometry: forward-scattered laser light was collected by a second identical objective lens, imaged onto a quadrant photodiode detector, and analyzed.
