General Description
The OV7910 (color) and OV7410/OV7411 (black and white) Single-
chip CMOS camera devices are designed to provide a high level of
functionality in a single small-footprint package. All three devices
support NTSC composite video and S-Video. The OV7910 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 OV7910/OV7410/OV7411
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.

SINGLE IC CMOS COLOR & B/W NTSC ANALOG CAMERAS
1. Functional Description
(Note: All references to color functions apply only to OV7910 image sensor)
1.1 Video Standards
Two TV standards are implemented and available as
output in the OV7910/OV7410/OV7411 imaging
devices: NTSC (M). Table 2 below shows how to con-
figure the standard of choice. Please note
that the accuracy and stability of the crystal clock fre-
quency is important to avoid unwanted color shift in TV/
video systems.

1.2 Video Formats
The OV7910/OV7410/OV7411 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, cre-
ating RGB or YUV component signals. At the same time, YUV signals are also processed to generate both com-
posite and S-Video signals. (Note: Color format configuration is valid only for the OV7910 image sensor)
1.2.1 Composite and S-Video
The Composite/S-Video format is the power-up default configuration for the OV7910/OV7410/OV7411 image sen-
sors. 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) out-
puts the CO component. Table 3 below summarizes the formats available and the settings required on the appro-
priate pins.
1.2.2 RGB
Setting AMOD0 = 1 (w/AMOD1 = x) selects the RGB format. In this configuration, RVCVO outputs the Red compo-
nent, GYYO outputs the Green component, and BUCO provides the Blue component.
1.2.3 YUV
Setting AMOD0=0 and AMOD1=1 configures the OV7910/OV7410/OV7411 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 OV7410 image sensor, only the GYYO (Y component) output is
valid.
