Mobile phone camera in the context of Picture


Images, encompassing forms like photographs and paintings, can be reproduced through various mechanical processes including photography and printmaking, and are fundamentally understood as distributed amplitudes of color when analyzed through signal processing.

⭐ In the context of signal processing, a mobile phone camera capturing an image fundamentally relies on what characteristic of light and color?


⭐ Core Definition: Mobile phone camera

A camera phone is a mobile phone that is able to capture photographs and often record video using one or more built-in digital cameras. It can also send the resulting image wirelessly and conveniently. The first commercial phone with a color camera was the Kyocera Visual Phone VP-210, released in Japan in May 1999. While cameras in mobile phones used to be supplementary, they have been a major selling point of mobile phones since the 2010s.

Most camera phones are smaller and simpler than the separate digital cameras. In the smartphone era, the steady sales increase of camera phones caused point-and-shoot camera sales to peak about 2010, and decline thereafter. The concurrent improvement of smartphone camera technology and its other multifunctional benefits have led to it gradually replacing compact point-and-shoot cameras.

HINT: Signal processing defines an image as a distribution of color amplitudes, meaning a camera sensor detects and records varying intensities of different colors to create a visual representation.

Mobile phone camera in the context of Image

An image or picture is a visual representation. An image can be two-dimensional, such as a drawing, painting, or photograph, or three-dimensional, such as a carving or sculpture. Images may be displayed through other media, including a projection on a surface, activation of electronic signals, or digital displays; they can also be reproduced through mechanical means, such as photography, printmaking, or photocopying. Images can also be animated through digital or physical processes.

In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term image (or optical image) refers specifically to the reproduction of an object formed by light waves coming from the object.
