Camera phone

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. 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 coupled with repurposed processing power that enabled fast image processing and high-resolution and frame rate video recording, and its other multifunctional benefits as a portable computing device have led to it gradually replacing compact point-and-shoot cameras. Most modern smartphones only have a menu choice to start a camera application program and an on-screen button to activate the shutter. Some also have a separate camera button for quickness and convenience. A few, such as the 2009 Samsung i8000 Omnia II or S8000 Jet, have a two-level shutter button as in dedicated digital cameras. Some camera phones are designed to resemble separate low-end digital compact cameras in appearance and, to some degree, in features and picture quality, and are branded as both mobile phones and cameras—an example being the 2013 Samsung Galaxy S4 Zoom. The principal advantages of camera phones are cost and compactness; indeed, for a user who carries a mobile phone anyway, the addition is negligible. Smartphones that are camera phones may run mobile applications to add capabilities such as geotagging and image stitching. Also, modern smartphones can use their touch screens to direct their cameras to focus on a particular object in the field of view, giving even an inexperienced user a degree of focus control exceeded only by seasoned photographers using manual focus. However, the touch screen, being a general-purpose control, lacks the agility of a separate camera's dedicated buttons and dial(s). Starting in the mid-2010s, some advanced camera phones featured optical image stabilisation (OIS), larger sensors, bright lenses, 4K video, and even optical zoom, for which a few used a physical zoom lens.
