n. a lightweight photographic camera with an autofocus
Wikipedia
A point-and-shoot camera, also called a compact camera, is a still camera designed primarily for simple operation. Most use focus free lenses or autofocus for focusing, automatic systems for setting the exposure options, and have flash units built in.
Point-and-shoots are by far the best selling type of separate camera, as distinct from camera phones. They are popular with people who do not consider themselves photographers but want easy-to-use cameras for snapshots of vacations, parties, reunions and other events. Point-and-shoot camera sales declined after about 2010 as smartphones overtook them in such uses.
Many superzoom compact cameras have optical zoom up to 30x and weigh less than 300 grams, much less than bridge cameras and DSLRs. All use 1/2.3" sensors. They prioritize intelligent Auto, but some high end P&S cameras have PSAM mode dial, Raw image format, and hotshoe. None have lens threads.
The term "point-and-shoot" is also used for some camcorders, particularly inexpensive digital models based on MiniDV or DVD media, to describe fully automatic operation ( autofocus, automatic gain control and white balance, etc.) with minimal operator interaction except for zoom control and recording buttons.
