Parallax- Parallax is an apparent displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.
Autofocus- An autofocus (or AF) optical system uses a sensor, a control system, and a motor to focus fully automatic or on a manually selected point or area.
Pixel- In digital imaging, a pixel, or pel, (picture element) is a single point in a raster image, or the smallest addressable screen element in a display device; it is the smallest unit of a picture that can be represented or controlled.
Aperture- In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane.
Shutter- In photography, a shutter is a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture a permanent image of a scene.
Exposure- In photography, exposure is the total density of light allowed to fall on the photographic medium (photographic or image sensor) during the process of taking a photograph. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance over a specified area.
Depth of field- In optics, particularly as it relates to film and photography, depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.
F-stop- In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system expresses the diameter of the entrance pupil in terms of the focal length of the lens; in simpler terms, the f-number is the focal length divided by the "effective" aperture diameter.
Focal length- The focal length of an optical system is a measure of how strongly the system converges (focuses) or diverges (defocuses) light.
The buttons I see on this camera are the shutter button and the flash button.
Shutter button- In photography, the shutter-release button (sometimes just shutter release or shutter button) is a button found on many cameras, used to take a picture.
Flash button- A flash button is a device used in photography producing a flash of artificial light (typically 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene.
