How we see better by 'looking away'

When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent ...

New algorithms give digital images more realistic color

If you've ever tried to capture a sunset with your smartphone, you know that the colors don't always match what you see in real life. Researchers are coming closer to solving this problem with a new set of algorithms that ...

Can sting rays and electric rays help us map the ocean floor?

Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have completed a feasibility study indicating that electric rays and sting rays equipped with pingers will be able to map the seabed through ...

Quantum materials quest could benefit from graphene that buckles

Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum ...

New imaging system creates pictures by measuring time

A radical new method of imaging that harnesses artificial intelligence to turn time into visions of 3-D space could help cars, mobile devices and health monitors develop 360-degree awareness.

Digital camera

A digital camera (or digicam for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.

Many compact digital still cameras can record sound and moving video as well as still photographs. In the Western market, digital cameras outsell their 35 mm film counterparts.

Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space. Some can crop pictures and perform other elementary image editing.

Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical devices are essentially specialised digital cameras.
