General Description
The OV7910P (color) and OV7410P/OV7411P (black and white) Single-chip CMOS camera devices are designed to provide a high level of functionality in a single small-footprint package. Both devices support composite video and S-Video. The OV7910P imager also provides RGB and YCrCb video signals, and each device directly interfaces with a VCR TV monitor or other 75 ohm terminated input. A minimum of external components are required to complete a fully functional camera subsystem. The OV7910P/OV7410P/OV7411P video cameras require only a single 5-volt DC supply and have been designed for very low power operation. These products are ideal for all applications requiring a small footprint, low voltage, low power and low cost color or black and white video camera.

1.1 Video Standards that the accuracy and stability of the crystal clock frequency is important to avoid unwanted color shift in TV/ video systems. Two TV standards are implemented and available as output in the OV7910P/OV7410P/OV7411P imaging devices: PAL (B). Table 2 below shows how to configure the standard of choice. Please note Table 2.

Video Formats
The OV7910P/OV7410P/OV7411P image sensors support a variety of formats including Composite (CVBS), S-Video (YO/CO), RGB components, YUV components, and B/W. Composite and S-Video signals are generated from the internal TV encoder and the RGB/YUV/BW outputs are generated from the color matrix prior to entering the encoder.
The image sensor utilizes the RG/BG Bayer pattern sending raw pixel data through the color matrix, creating RGB or YUV component signals. At the same time, YUV signals are also processed to generate both composite and S-Video signals. (Note: Color format configuration is valid only for the OV7910P image sensor) 1.2.1 Composite and S-Video
The Composite/S-Video format is the power-up default configuration for the OV7910P/OV7410P/OV7411P image sensors. Pins AMOD0/AMOD1 (pins 38 and 39) select composite and S-Video formats. In this configuration, RVCVO (pin 17) outputs CVBS, GYYO (pin 16) outputs the YO component of the S-Video signal, and BUCO (pin 15) outputs the CO component. Table 3 below summarizes the formats available and the settings required on the appropriate pins.
1.2.2
RGB Red component, GYYO outputs the Green component, and BUCO provides the Blue component.
Setting AMOD0 = 1 (w/AMOD1 = x) selects the RGB format. In this configuration, RVCVO outputs the 1.2.3 YUV
Setting AMOD0=0 and AMOD1=1 configures the OV7910P/OV7410P/OV7411P sensors to operate in YUV or B/W mode. In this configuration, GYYO outputs the Y component, RVCVO provides the Cr component,
and BUCO outputs the Cb component. On the OV7410P image sensor, only the GYYO (Y component) output is valid.

Configuring the OV7910P/OV7410P/OV7411P Image Sensors for Operation
to all
The OV7910P/OV7410P/OV7411P sensors have been designed for easy-of-use in many stand-alone applications. Most of the on-chip functions are configurable by connecting appropriate pins high (logic "1") or low (logic "0") through a 10k Ohm resistor. The image sensor reads the input the pins at power up, which enables user-defined default configurations. The OV7910P/OV7410P/OV7411P imaging devices also contain an I2C interface for programmatic access sensors will enable the I2C port for access.
register functions (For further details on I2C, see Section 2. "I2C Bus" on page 11). By default, the I2C port is disabled. To enable the I2C for controlling the sensors, a 10K Ohm pull-up resistor must be connected to FODD/I2CEN. With FODD/I2CEN pulled high at power-up, the OV7910P/OV7410P/OV7411P image AWB is enabled, the image sensors continuously perform white balancing. A fast or slow mode of white balancing may be user-selected (AWBTM, pin 30). Fast AWB updates color every 2 fields while slow
1.4
White Balance
The function of white balance in the OV7910P image sensor is to adjust and calibrate the image devices sensitivity on the primary (RGB) colors to match the color cast of the light source. The Auto White Balance (AWB) can be enabled or disabled either through an external pin (AWBEN, pin 29) or through the I2C port. If able only through the I2C port. This function enables the user to define a "cooler" or "warmer" background for image capture.
white balancing updates every 16 fields. By using the I2C port, the color temperature may be further fine tuned to the requirement of the application. Note that the "blue" (Blue and Blue bias registers) and "red" (Red and Red bias registers) bias control is availand Backlight control. HGAIN (pin 20) may be used to set the range of AGC Gain. A "0" on HGAIN sets AGC Gain range for 1X <-> 4X, while a "1" sets the range for 1X <-> 8X. G2X (pin 19) can then be used to enhance the AGC gain range.
1.5
Additional Picture Control A "0" on G2X sets AGC gain at normal. A "1" enhances the AGC gain by 2 (Refer to Table 1, "Pin Description," on page 2, pins 19 and 20 for further details). This function may be configured through the I2C port, as December 7, 1999
A number of functions/registers are available which enable the user to configure OV7910P/OV7410P/ OV7411P image capturing parameters. These functions include Automatic Gain Control (AGC), AGC Gain, Automatic Exposure Control (AEC), GAMMA, 6 Version 1.4

well. GAMMA (pin 27) can be used to set the GAMMA correction. BKLT (pin 21) controls how the OV7910P/ OV7410P/OV7411P image sensors manage backlight conditions. These functions may also be controlled through the I2C interface. At power up, AGC and AEC are enabled. AGC can be disabled at power up by configuring the AGCEN pin (pin 28) as required. AEC cannot be enabled/disabled externally and must be reprogrammed through the I2C port. 1.6 Other Image Sensor Control Functions

capability is enabled (I2CEN = 1),the OV7910P/ OV7410P/OV7411P imager operates as a slave device that supports up to 400 kbps serial transfer

that the read cycle can be terminated. Note that the restart feature is not supported here.
2.1
I2C Bus Protocol Format Within each byte, MSB is always transferred first. Read/write control bit is the LSB of the first byte. Standard I2C communications require only two pins: SCL and SDA. SDA is configured as open drain for bidirectional purpose. A HIGH to LOW transition on the SDA while SCL is HIGH indicates a START condition. A LOW to HIGH transition on the SDA while SCL is HIGH indicates a STOP condition. Only a master can generate START/STOP conditions. Except for these two special conditions, the protocol that SDA remain stable during the HIGH period of the clock, SCL. Each bit is allowed to change state only when SCL is LOW (See Figure 4. Bit Transfer on the I2C Bus and Figure 5. Data Transfer on the I2C Bus
In I2C operation, the master must perform the following operations:
n Generate the start/stop condition n Provide the serial clock on SCL n Place the 7-bit slave address, the RW bit, and the 8-bit subaddress on SDA
The receiver must pull down SDA during the acknowledge bit time. During the write cycle, the OV7910P/ OV7410P/OV7411P device returns the acknowledgment and, during read cycle, the master returns the acknowledgment except when the read data is the last byte. If the read data is the last byte, the master does not perform an acknowledge, indicating to the slave below).

The OV7910P/OV7410P/OV7411P I2C supports multibyte write and multi-byte read. The master must supply the subaddress. in the write cycle, but not in the read cycle. Therefore, the OV7910P/OV7410P/OV7411P takes the read subaddress from the previous write cycle. In multi-byte write or multi-byte read cycles, the subaddress is automatically increment after the first data byte so that continuous locations can be accessed
in one bus cycle. A multi-byte cycle overwrites its original subaddress; therefore, if a read cycle immediately follows a multi-byte cycle, you must insert a single-byte write cycle that provides a new subaddress. The OV7910P/OV7410P/OV7411P supports a single slave ID. The ID is preset to 80 write and 81 for read. In the write cycle, the second byte in I2C bus is the subaddress for selecting the individual on-chip registers, and the third byte is the data associated with this register. Writing to an undefined subaddress is ignored. In the read cycle, the second byte is the data associated with the previous stored subaddress. Reading of undefined subaddresses returns unknown data. 2.2 Register Set
