Hardware and software ("firmware"), built into the camera, measures luminance of the subject and automatically sets shutter speed, lens aperture or sensitivity; this also allows the camera to set the aperture for manual lenses fixed with an AE chip. [4] AE-L or AEL: Automatic exposure lock. Technology for holding an exposure setting from one ...
XQD card format was the last new form of card, targeted at high-definition camcorders and high-resolution digital photo cameras. Most modern digital cameras also use internal memory of limited capacity to hold pictures temporarily, regardless of whether or not the camera is equipped with a memory card. These pictures can then be transferred ...
Onboard (internal) flash memory — Cheap cameras and cameras secondary to the device's main use (such as a camera phone). Some have small capacities such as 100 Megabytes and less, where intended use is buffer storage for uninterrupted operation during a memory card hot swap .
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level depending on ...
A dashboard camera or simply dashcam, also known as car digital video recorder (car DVR), driving recorder, or event data recorder (EDR), is an onboard camera that continuously records the view through a vehicle's front windscreen and sometimes rear or other windows. Some dashcams include a camera to record the interior of the car in 360 ...
The card lets any digital camera with an SD slot transmit captured images over a wireless network, or store the images on the card's memory until it is in range of a wireless network. Examples include: Eye-Fi / SanDisk, Transcend Wi-Fi, Toshiba FlashAir, Trek Flucard, PQI Air Card and LZeal ez Share. [144] Some models geotag their pictures.
With use 1/2.3" small sensor as commonly is used by bridge cameras, the camcorder has 20x optical zoom in a compact body with dual XLR audio inputs, Internal ND filters and separate control rings for focus, iris and zoom. In HD capture, the camcorder enables in-camera downscaling of the 4K image to HD to reduce noise inherent in the smaller sensor.
The camera is capable of recording in both HDV and DV formats, on MiniDV, though it's unable to record 24p in the DV format. The camera uses a 1/2.7" CMOS sensor, which is shared with other consumer high definition cameras manufactured by Canon, such as the HV10, HR10 and HG10. The replacement for the HV20, the HV30, was released in March 2008 ...
