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.

2. Functional Description
ICM-515NB is a single-chip digital color imaging device. It includes a 574x483 sensor array, 574 column-level
ADC, correlated double sampling circuitry, an automatic exposure control module, a color interpolation module,
programmable white balancing, a color correction module and a programmable gamma correction module. All the
programmable parameters are set by writing into the SIF interface which can address the register file consisting of
8-bit registers. The output format is NTSC composite video,
which includes
horizontal and vertical sync signals.

2.1 Image Array
The image array consists of 574x483 pixels. Each pixel has a light sensitive photo diode and a set of control and
transfer transistors. At the beginning of the cycle, a row of pixels is pre-charged to its maximum value. Then the
row is exposed to light for several lines worth of time and sampled by the ADC. A "Correlated Double Sampling
(CDS)" process is performed with subtracting the reset value (sampled right before sampling the signal) from the
signal value. The purpose of CDS is to eliminate the point-wise fixed pattern noise (FPN). The output of CDS is
approximately proportional to the amount of received light, ranging from 0 to 512.
