Die Bildwiederholfrequenz (oder auch Bildrate) gibt an, wie viele Einzelbilder das Gerät pro 1 Sekunde Video aufnehmen kann bzw. wie viele Bilder pro Sekunde das Anzeigegerät anzeigen kann. Die Bildrate bei Videos wird in der Einheit fps (Bilder pro Sekunde) und bei Fotos in der Einheit fps (Bilder pro Sekunde, englisch: frames per second) angegeben. Bei Videos gilt: je höher die Bildrate, desto flüssiger das Bild. Höhere Bildwiederholfrequenzen gehen jedoch in der Regel auf Kosten der Auflösung.
Video formats mark a file format of a recorded video. The format helps you find out whether the video can be played on your TV. There are a number of both free and paid programs which convert video files to supported formats.
A compact camera where the image captured by the lens is projected electronically onto a miniature display. Its lack of an optical system means makes it significantly lighter and more portable. Another nice bonus is the ability to view the image on the display with effects already applied.
Timelapse is a technique where the frequency at which film frames are captured is set at specific intervals. The camera captures hundreds or thousands of photos in succession and then the result is played back, creating a stunning movie. One significant drawback of this type of photography is its relatively fast shutter wear compared to the lens, especially when shooting at close range. These days, however, you are far more likely to find a camera with a preview LCD display instead.
During exposure you expose the camera sensor to light emitted by the captured scene. Exposure is defined by three basic parameters, which are sensitivity (ISO), aperture (F), and exposure time. The higher the maximum ISO and the lower minimum aperture, the less time you need to capture the shot and the easier it is to avoid blurring. This comes in handy if you like to photograph sports, racing, and other objects in motion, or like shooting night-time scenery.
Resolution indicates the number of pixels that make up an image or video. A lot of modern devices are equipped with Full HD resolution (1920 x 1080), which is suitable for display on large screen TVs or monitors. Higher resolution provides smoother images with more detail.
Optical stabilization is a mechanism inside the lens that eliminates the effects of camera / lens shake on the captured image. This is done by moving the optical system inside the lens. It is often referred to as OIS (Optical Image Stabilizer). It reduces the camera shake and blur, for example at slow shutter speeds or long focal length lenses.
Micro SD cards are used for storing data on mobile phones, GPS navigation and other portable devices.
