Functional Description (Note: All references to color functions apply only to OV7910P image sensor) 1.1 Video Standards 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 that the accuracy and stability of the crystal clock frequency is important to avoid unwanted color shift in TV/ video systems. Table 2. Standard Configuration Standard PAL 1.2 PAL (pin 24) 1 Clock Comments 17.734475 MHz clock in = 4 x Fsc Video Formats 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) 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. 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 1.2.2 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. 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, December 7, 1999 and BUCO outputs the Cb component. On the OV7410P image sensor, only the GYYO (Y component) output is valid. Version 1.4 5 Preliminary OMNIVISION TECHNOLOGIES, Inc.

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 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. 1.5 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 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. Additional Picture Control 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 to all 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 sensors will enable the I2C port for access. 1.4 (Pins 15 & 17 are undefined on the OV7410P sensor) Version 1.4 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 Preliminary OMNIVISION TECHNOLOGIES, Inc. OV7910P/OV7410P/OV7411P SINGLE IC CMOS COLOR & B/W PAL ANALOG CAMERAS 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 OV7410P/OV7411P image sensors include sharpness adjustment, brightness level fine tune, color saturation adjustment, mirror image control, and power down. All of these functions (except power down) can be configured either by an external pin or through the I2C interface.

Note that the restart feature is not supported here. 2.1 I2C Bus Protocol Format 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 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 below).

Data Transfer on the I2C Bus RW SDA SLAVE ID SUB ADD A SCL S 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 The table below provides a list and description of available I2C registers contained in the OV7910P/OV7410P/ OV7411P image sensor.
