Task: Question Answering
Input (English): Context: A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers., An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished by their type as being either active, passive or hybrid variants., A rangefinder is a device that measures distance from the observer to a target, in a process called ranging., A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic medium such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating photographs is called photography. The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek  ("phos"), meaning "light", and  ("graphê"), meaning "drawing, writing", together meaning "drawing with light"., A still camera is a type of camera used to take photographs. Traditional cameras capture light into photographic film. Digital cameras use electronics, usually a charge coupled device (CCD) to store digital images in computer memory inside the camera. The digital image can be transferred to a computer for later processing., In the broadest definition, a sensor is an object whose purpose is to detect events or changes in its environment and sends the information to the computer which then tells the actuator (output devices) to provide the corresponding output. A sensor is a device that converts real world data (Analog) into data that a computer can understand using ADC (Analog to Digital converter), Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit., Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film., 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 ., A control system manages, commands, directs or regulates the behaviour of other devices or systems. It can range from a home heating controller using a thermostat controlling a domestic boiler to large Industrial control systems which are used for controlling processes or machines. , Subject: point-and-shoot camera, Relation: instance_of, Options: (A) area (B) base (C) camera (D) charge (E) computer (F) computer memory (G) data (H) definition (I) design (J) device (K) drawing (L) electronics (M) emulsion (N) environment (O) film (P) human (Q) hybrid (R) information (S) photograph (T) photography (U) point (V) process (W) range (X) role (Y) scene (Z) science ([) sensor (\) side (]) still camera (^) system (_) writing
