SINGLE IC CMOS COLOR & B/W PAL ANALOG CAMERAS

Preliminary

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.

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 unde-

fined subaddresses returns unknown data.

GC[7] - unimplemented bit, returns ‘X’ when read.

GC[6:0] – Storage for the current AGC Gain setting.

This register is updated automatically. If AGC is enabled, the internal control stores the optimal

gain value in this register. IF AGC is not enabled, a “00” is stored in this register.

RW

Storage for the current blue channel setting for white balance control.

BLU[7] – “0” decrease gain, “1” increase gain.

BLU[6:0] – blue channel gain balance value.

Note: This function is not available on the OV7410P/OV7411P Image Sensor.

Red[7:0]

Storage for the current red channel setting for white balance control.

RED[7] – “0” decrease gain, “1” increase gain.

RED[6:0] – red channel balance value.

byte 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
