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.

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:
Vo = Vi1 /
where Vi is normalized (ranged from 0 to 1) R, G, or B signal coming from the white balancing module, and Vo is 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 H inductor and two 560 pF capacitors, before connecting to a 75 cable.

(*) Synchronized with frame begin. (**) Need PART_CONTROL[7] to change value, which synchronizes with frame begin. (R) Read only 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)
