The digital era is full of amazing developments in the camera technology. Gadgets are occasionally updated with high megapixels to give consumers clear and memorable camera experience. The most current camera research is focusing on computational processing and its fusion with camera data. Contrary to what normal cameras do, this new approach would experience a sequence of mathematical computations before giving an image. This extra computational processing may only demand light detectors to give high-quality imaging that can aid in viewing inside the human body and behind walls. Pixels are tiny light sensors fitted in cameras.

A single pixel camera operates on the principle that information can be captured from numerous light sources. The light sources are controlled, illuminated in several patterns, measured and a complete image developed. A major challenge for this method is the need to illuminate many spots to produce an image. The good thing about this method is the ability to create images from light travelling at very long wavelengths, which are invisible in the light spectrum.

Multi-sensor imaging focuses on the principle that light can be detected by several sensors and concentrated on one point. The Hubble telescope is an original example of a multisensory camera. Lytro camera is a modern version available for commercial use.

Camera researchers predict that the next generation may have a camera resembling Light L16 camera. The camera is expected to have ten sensors and produce a 50Mb professional image. The researchers are engaging in an intensive study on the use of artificial intelligence to process data and produce images.
