Mosquitoes are insects which make up the family Culicidae . They have a pair of scaled wings, a pair of halteres, a slender body, and long legs. The females of most mosquito species suck blood (hematophagy) from other animals, which has made them the most deadly disease vectors known to man, killing millions of people over thousands of years and continuing to kill millions per year by the spread of diseases.

Length varies but is rarely greater than 16 mm (0.6 inch), and weight up to 2.5 mg (0.04 grain). A mosquito can fly for 1 to 4 hours continuously at up to 1–2 km/h travelling up to 10 km in a night. Most species are nocturnal or crepuscular (dawn or evening) feeders. During the heat of the day most mosquitoes rest in a cool place and wait for the evenings. They may still bite if disturbed.

Ring ( リング , Ringu ^? ) is a 1998 Japanese horror mystery film from director Hideo Nakata, adapted from the novel of the same name by Koji Suzuki, which draws from the Japanese folk tale Banchō Sarayashiki. The film stars Nanako Matsushima, Hiroyuki Sanada, and Rikiya Otaka as members of a divorced family, each cursed by a videotape. The film was later remade in Korea as The Ring Virus (1999), and in the United States as The Ring (2002).

The film is the highest grossing horror film in Japan at 15.9 billion yen ($137.7 million) and is also considered the most frightening horror movie in Japan according to the investigation of Oricon.

Tone mapping is a technique used in image processing and computer graphics to map a set of colours to another; often to approximate the appearance of high dynamic range images in media with a more limited dynamic range. Print-outs, CRT or LCD monitors, and projectors all have a limited dynamic range which is inadequate to reproduce the full range of light intensities present in natural scenes. Essentially, tone mapping addresses the problem of strong contrast reduction from the scene values (radiance) to the displayable range while preserving the image details and color appearance important to appreciate the original scene content.
