A point-and-shoot camera, also called a compact camera, is a still camera designed primarily for simple operation.〔(Brittanica Article )〕 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.〔(【引用サイトリンク】title=Sony Cyber-shot HX50 review )〕 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. == As distinct from SLR == Point-and-shoot cameras are distinguished from single-lens reflex cameras (SLRs) in several respects: point-and-shoot film cameras, and many digital ones, use a viewfinder. The image that the photographer sees is not the same image that passes through the primary lens of the camera (that is, the lens that projects the image onto the film or, in the case of digital cameras, the image sensor). Rather, the image in the viewfinder passes through a separate lens.〔http://www.wujimedia.com/2009/11/point-and-shoot-v-dslr-cameras-part-i/〕 SLRs, on the other hand, have only one lens, and a mirror diverts the image from the lens into the viewfinder; that mirror then retracts when the picture is taken so that the image can be recorded on the film or sensor. With this mechanism, pictures cannot be previewed on the LCD screens of most digital SLRs, although some manufacturers have found a way around this limitation. Digital cameras obviate the need for the SLR design to some degree, as the camera's LCD image is obtained through the lens, not a separate viewfinder. Many newer and smaller digital point-and-shoots omit the optical viewfinder. With SLR cameras, it is important that the image in the viewfinder be the same image recorded by the film or sensor, so that the effect of the add-on lenses and filters can be seen by the photographer. Point-and-shoot cameras generally don't have such add-on devices, hence there is no such need. The size limitations of compact and ultra-compact cameras, including digital ones, encourage the occurrence of photographic orbs — unexpected, typically circular artifacts that occur in flash photographs — where the short distance between the lens and the built-in flash decreases the angle of light reflection to the lens, ''directly'' illuminating the aspect of the normally sub-visible particles facing the lens and increasing the camera's ability to capture the light reflected off the particles.〔(【引用サイトリンク】 publisher = )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Point-and-shoot camera」の詳細全文を読む スポンサード リンク
