Image stabilization is a technology used in digital cameras and lenses to reduce blur caused by camera movement. There are different types of image stabilization, including optical, electronic and image stabilization on the sensor (IBIS). Each type has its advantages and disadvantages, but all aim to improve image quality when shooting handheld or at low shutter speeds.

Sensors (chips, sensors) of digital cameras record video information when photographing an object and then send it to the processor. According to the manufacturing technology they are divided into...

The size of the sensor determines how much light falls on the chip. 

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.

Compact cameras usually have an aspect ratio of the sensor 4:3, powerful equipment can have 2:3 or 3:2. Available are also variations, such as 16:10, 16:9, 5:4, etc.  

Minimum time that the shutter is open, allowing light to strike the image sensor. Fast shutter speeds are used for taking quick action shots to capture sharp images.

The maximum time that the shutter is open, allowing light to strike the image sensor. Slow shutter speeds are used for a variety of shots with special effects or with targeted out of focus images.

ISO specification indicates the camera sensor's sensitivity to light. Higher sensitivity is primarily used in low light conditions to avoid unwanted noise and blur.

Sekvenčné snímanie predstavuje fotografický záznam deja zachytený v sérii snímok idúcich za sebou. Využitie nájde najmä pri fotografovaní rýchlej akcie a športu. Bežné digitálne fotoaparáty dokážu snímať v rýchlosti 2 – 3 snímky za sekundu, výrazne lepšie na tom budú digitálne zrkadlovky, najrýchlejšie sú všeobecne bezzrkadlovky.

Resolution refers to the number of pixels of one frame of the movie. It affects the video quality during playback or editing. 

Video sound reinforcement is the process of recording sound when making a video. The type of sound that is recorded can have a significant impact on the overall quality of the video. Different types of video sound reinforcement include mono, stereo and surround sound. These types of sound offer different levels of sound depth and spatial orientation that can enhance the video viewing experience.

Lenses for cameras vary based on several different factors, including type, construction, focal length, and maximum aperture. The two basic types of lenses are fixed focus (prime) and zoom. Fixed lenses have a single focal length and are generally considered to be able to provide sharper and clearer images than zoom lenses. Zoom lenses allow you to vary the focal length and thus adjust the level of zoom in or out.

The minimum focal length is the smallest distance at which the lens can be focused. This value is usually given in millimetres and is a determinant of how close to the subject the camera can focus. Cameras with a lower minimum focal length can focus on objects that are closer to the lens.

The maximum focal length is the greatest distance at which the lens can be focused. This value is usually given in millimetres and is a determinant of how far away from the lens the camera can focus. Cameras with a higher maximum focal length can focus on objects that are further away from the lens.

Lens speed (f), indicates how much light the lens is capable of shooting to render the subject. It is the ratio of the diameter of the aperture input and focal length.

Focal length is a fundamental specification of every Lens. It is the distance between the optical center of the lens and the plane on which the lens can focus on the subject, ie where they intersect the light that passes through the lens.

Specifies the diagonal measurement of the screen in inches. 

Type of the power supply of the camera. It can be classical battery (could be rechargeable), or a special acumulator.

The number of shots for the acquisition of which is sufficient battery/acumulator on a single charge.
