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.

Figure 1. Block diagram

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.

2.2 Color Filters and Image Signal Processing

Each pixel is covered by a color (R, G, or B) filter. Since each pixel only gets part of the spectral band, the data
need further processing (i.e., color interpolation and color correction) in order to produce the full visible spectrum
for best image quality.

ICM-515NB incorporates the following digital signal processing functions.

An automatic exposure (AE) time control to accommodate for different brightness, the AE feature will adjust the
exposure time thru various gain control mechanisms to achieve the appropriate brightness.

An anti-flickering control circuit to eliminate flickering caused by a 50Hz or 60Hz light source normally found
indoors.

A color interpolation and Automatic White Balance (AWB) module to perform color interpolation and gain on
each color pixel to obtain a set of correlated RGB value for each pixel. The result of this operation is a data stream
consisting of 24-bit RGB per pixel with balanced color components.

A color control module to adjust color contrast, hue, and saturation.

To boost darker signal to match the video monitor characteristic, gamma correction are performed:

where V

is normalized (ranged from 0 to 1) R, G, or B signal coming from the white balancing module, and V

normalized final output. The parameter

is programmable with default value of 2.2.

2.3 Output Format

The output format of ICM-515NB is analog composite video output suitable for TV display. This output is tied
through a parallel 75

ohms resistor to ground, and to a pi-network of one 1.7 µH inductor and two 560 pF

capacitors, before connecting to a 75

cable.

ICM515NB can work in three modes:

a. Normal Mode: RAW sensor data output from DOUT[9:0], TV signal output on CPOUT
b. DSP Test Mode: Test patterns including column addresses generated on-chip as input,

encoded as digital CVBS output to DOUT[9:0]

c. DAC Test Mode: external data can be applied to pins DOUT[9:0] to test DAC directly.

When captured by rising edge of PCLK, the output may have 1 clock delay if using
DAC's LOOKAHEAD structure. Normal DAC mode will not have delay.

The three modes are controlled by:
AD-INOUTSEL(0X52), AD_DSP_CTRL(0X2f), TIMING_CONTROL_LOW(0X01)
