Chrominance (chroma or C for short) is the signal used in video systems to convey the color information of the picture, separately from the accompanying luma signal (or Y for short).
A digital camera or digicam is a camera that captures photographs in digital memory.
A digital single-lens reflex camera (also called digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.
Gamma correction, or often simply gamma, is a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems.
A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency.
Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise.
An image processor, image processing engine, also called media processor, is a specialized digital signal processor (DSP) used for image processing in digital cameras, or other devices.
A low-pass filter (LPF) is a filter that passes signals with a frequency lower than a certain cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency.
Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction.
is a Japanese manufacturer of optics and reprography products.
