General Description
ICM-515NB is a single-chip digital color video imaging device. It incorporates a 574x483 sensor array (584x493 in
physical layout) operating at 30 frames per second (60 fields/sec) in interlaced manner. Correlated double sampling
is performed by the internal ADC and timing circuitry. Depending on the brightness of the scene, the raw data can be
adjusted by an automatic (or manual) exposure control (AE). The raw data are further processed by a color
interpolation module so that each pixel gets a complete set of RGB values. To correct or enhance color, white
balancing and color correction are also performed automatically on chip. At the next stage, the gamma correction can
also be performed. After these digital processing steps, the signal is fed to an embedded NTSC encoder that generates
composite video output to be sent to a TV for display.
