Types of digital cameras

There is a vast array of sizes, costs, and features available for digital cameras. Specialized cameras, such as astrographs and multispectral imaging equipment, are utilized for scientific, military, medical, and other unique reasons in addition to general-purpose digital cameras.

A subcompact camera with a retractable lens assembly is the DSC-W170.

small digital camera disassembled. Compact cameras are meant to be small and lightweight, making them ideal for “snapshots” on the go. Typically, point-and-shoot cameras are included in this group.

Many include an optical zoom feature that is provided via a retractable lens component. The majority of models have an auto-actuating lens cover to shield the lens from the weather. The majority of devices that are water-resistant, ruggedized, or have superzoom capabilities do not retract all the way.

The majority of compact cameras are made to be simple to operate. Nearly all have an “Auto mode” is the term for the automatic mode that sets all camera settings for the user. A few additionally feature manual controls. Small sensors found in most tiny digital cameras sacrifice image quality in favor of portability and simplicity; lossy compression is frequently the only option for storing photos (JPEG). Most have an inbuilt flash, usually with low strength that is adequate for subjects that are close by. A hotshoe for attaching an external flash is present on a few premium small digital cameras. Almost always, an integrated LCD is utilized to frame the photo using live preview. Virtually all compact cameras have the capacity to record video in addition to still images.

Zoom lenses and macro capabilities are common in compacts; nonetheless, the zoom range (up to 30x) is usually sufficient for candid photography, but not as much as the interchangeable lenses of DSLR cameras, which are available at a significantly higher cost, or the more than 60x zoom offered on bridge cameras.[43] Compact digital cameras’ autofocus systems are typically built around a contrast-detection technique that makes use of picture data from the primary imager’s live preview feed. Certain small digital cameras make use of a hybrid focusing technology, which is comparable to that found on most DSLRs.

Compact digital cameras usually include a leaf shutter built into the lens that is almost silent, but for skeuomorphic effects, they play a fake camera sound.

These cameras usually use image sensor types with a diagonal between 6 and 11 mm, equating to a crop factor between 7 and 4, due to their low cost and tiny size. This provides them with smaller components, poorer low-light performance, deeper field of view, and generally less precise focusing than cameras with larger sensors. Certain cameras employ a larger sensor than others, such as the high-end Sony Cyber-shot DSC-RX1, a costly compact camera with a full-frame sensor, although its capabilities are comparable to those of a DSLR.

A wide range of extra functions are available based on the camera model. These characteristics consist of altimeters, barometers, GPS, and compass.[44]

Some small digital cameras have been able to capture 3D still images since 2010.[45] With either one or two lenses, these 3D small stereo cameras can take 3D panoramic images that may be viewed on a 3D TV.

To be used with a smartphone or tablet, Sony produced two add-on camera models without a display in 2013. via WiFi, under the direction of a smartphone application.[46]

Rugged compact cameras are usually sealed against pressure, shock, hot and cold temperatures, and submersion. These qualities are referred to as being waterproof, freeze-proof, heat-proof, shock-proof, and crush-proof, in that order. Almost every significant camera manufacturer offers at least one item in this category. Only a handful will float, but some are waterproof down to a significant depth of up to 100 feet (30 m);[47] others are only 10 feet (3 m). While most rugged cameras are capable of recording voice and capturing video, they frequently lack some of the functionality found in regular small cameras. The majority have integrated flash and image stabilization. Underwater, GPS and touchscreen LCD are inoperable.

Action cameras

Action is available from brands like GoPro.

tough, compact cameras that are simple to fasten to bicycles, helmets, arms, and other surfaces. Most can capture still images and videos, usually with sound, and have a wide angle and fixed focus.

cameras in 360 degrees
Overview: 360-degree panoramic camera
The 360-degree camera may simultaneously shoot with two lenses pointed in different directions to capture 360-degree images or videos. Ricoh Theta S, Nikon Keymission 360, and Samsung Gear 360 are a few of the cameras. When Nico360 was introduced in 2016, it was touted as the tiniest 360-degree camera in the world, measuring 46 x 46 x 28 mm (1.8 x 1.8 x 1.1 in) and costing less than $200. Live streaming is possible thanks to Bluetooth, WiFi, and built-in stitching for virtual reality mode. Because it is also water resistant, the Nico360 can be used as action camera.[48] There are tend that action cameras have capabilities to shoot 360 degrees with at least 4K resolution.[49]
