VV5404 & VV6404
®
Mono and Colour Digital Video CMOS Image Sensors
DESCRIPTION
VV5404 and VV6404 are highly integrated CMOS VLSI
sensors which enables high standards of performance and
image quality at a very cost-effective price point. The 356 x
292 monochrome device offers one of the simplest routes
currently available to design-in of imaging applications, while
the colour device is ideal for low cost PC camera applications.
Both devices incorporate a comprehensive range of on-board
controls eliminating the need for additional support chips. On-
chip A/D conversion provides 8 bit digital output and the
device set up is fully automatic via the built-in automatic black
level calibration algorithm.
Exposure and gain settings are programmable and operation
is controlled via a serial interface.
This sensors offer variable frame rates of up to 30 frames per
second and a 4 wire digital video bus. The digital interface
also provides a tri-stateable data qualification clock and frame
synchronisation signal.
Hand-held products, in applications such as PDAs, bar code
scanning or automatic meter reading, will benefit from the low
power requirements and from the inbuilt sleep and power
down modes.
The price and performance standards introduced with the
VV5404 and VV6404 enable use of an imaging solution
where previously it may not have been practicable on cost
grounds.

Important:
1. A colour co-processor is required to convert the VV6404 sensor’s video
data stream of raw colourised pixel data into either a CIF or QCIF for-
mat RGB or YUV colour image.
2. VV5404 and VV6404 do NOT have any form of automatic exposure
control. This must be performed externally.

2. Operating Modes
2.1 Image Read-out Options
The output image format is CIF (352 x 288 pixel array). To provide the colour co-processor with the extra information
it needs for interpolation at the edges of the VV6404 pixel array, an optional border 2 pixels deep on all 4 sides of the
array can be enabled (Figure 4). The resulting image size of 356 x 292 pixels is the default power up state for this
camera module. The border option is programmable via the serial interface.

Figure 3 : Bayer Colourisation Pattern. (VV6404 only)
Image read-out is either non-interlaced raster scan, or ‘shuffled’ non-interlaced raster scan.
The shuffled raster scan order differs from a conventional raster in that the pixels of individual rows are re-ordered,
with the odd pixels within a row read-out first, followed by the even pixels.
This ‘shuffled’ read-out within a line, is useful in the VV6404 device as it groups pixels of the same colour (according
to the Bayer pattern - Figure 3) together, reducing cross talk between the colour channels.
NOTE: This option is on by default in both VV5404 and VV6404 sensors and is controllable via the serial interface.
2.2 Frame Rate Options
Two options: 30 fps or 25 fps (Assuming a 7.15909 MHz input clock and the default clock divider setting). The number
of video lines in for each frame rate is the same (304), the slower frame rate is implemented by extending the line
period from 393 pixel periods to 471 pixel periods. 30 fps is the default option, the frame rate is programmable via the
serial interface.
