List of digital video cameras with an image sensor larger than 2/3 inch and producing video in a horizontal resolution equal or higher than 1920 pixels.
Almost all include an automatic mode, or "auto mode", which automatically makes all camera settings for the user. Some also have manual controls. Compact digital cameras typically contain a small sensor that trades-off picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG).
Digital video is an electronic representation of moving visual images in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 25, 30, or 60 frames per second ...
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras.
Practical digital video cameras were also enabled by advances in video compression, due to the impractically high memory and bandwidth requirements of uncompressed video. [8] The most important compression algorithm in this regard is the discrete cosine transform (DCT), [ 8 ] [ 9 ] a lossy compression technique that was first proposed in 1972 ...
Some Nikon Coolpix cameras which are not advertised as supporting a RAW image format can actually produce usable raw files if switched to a maintenance mode. [26] Note that switching to this mode can invalidate a camera's guarantee. Nikon models with this capability: E700, E800, E880, E900, E950, E990, E995, E2100, E2500, E3700, E4300, E4500.
Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
Electronic by nature, most digital cameras are instant, mechanized, and automatic in some or all functions. Digital cameras may choose to emulate traditional manual controls (rings, dials, sprung levers, and buttons) or it may instead provide a touchscreen interface for all functions; most camera phones fall into the latter category.
