A tape video camera is a digital camera using a magnetic tape as a storage medium.
A type of camera that uses a flash memory card to store image files has the advantage of being compact and easy to carry. However, due to the limitations of the flash memory card itself, the flash memory camera has a faster reading speed and a larger capacity than a hard disk camera.
The hard disk type digital video camera uses a micro hard disk as the storage medium. Similar to a recordable optical disk, the micro hard disk can also be reused.
The amount of exposure is the most primitive key factor in the image composition. It is mainly determined by the aperture and the shutter.
The minimum illuminance is also called sensitivity, which is the sensitivity of the CCD to ambient light, or the darkest light required by the CCD for normal imaging. The smaller the value of the illuminance, the less light is required and the more sensitive the camera is.
Digital cameras rely on the optical lens structure to achieve zooming. Its optical zooming method is similar to that of traditional 35mm cameras. It uses lens movement to zoom in and out of the scene to be captured. The larger the optical zoom factor, the farther the scene can be captured.
A shutter is a device that blocks light from entering the lens. Generally speaking, the larger the shutter's time range, the better.
The CCD is made of a high-sensitivity semiconductor material that can convert light into an electric charge. The photosensitive element on it is called a "pixel". The larger the number of CCD pixels and the larger the single pixel size, the sharper the collected image will be.
