OV6620/OV6120

SINGLE IC CMOS COLOR AND B/W DIGITAL CAMERAS

Advanced Information

Preliminary

Notes:

A. Y port output data sequence: G R G R G R ... or G G G G ... ; UV port output data sequence: B G B G B G ... or B R B R ... ;

Array Color Filter Patter is Bayer-Pattern

B. Output Modes

16-bit Format (HREF total 292)

Default mode:

– Every line of data is output twice.

YG mode:

– 1st HREF Y and UV output unstable data.

– Every line data output twice.

One line mode:

– UV channel tri-state.

8-bit Format (HREF total 292)

– 1st HREF Y channel output unstable data.

– 2nd HREF Y channel output B11 G21 R22 G12 ...

– 3rd HREF Y channel output B31 G21 R22 G32 ..., etc.

– PCLK timing is double and PCLK rising edge latch data bus. UV channel tri-state. Every line data output twice.

4-bit Nibble Mode Output Format

– Uses higher 4 bits of Y port (Y[7:4]) as output port.

– Supports YCrCb/RGB data, CCIR601/CCIR656 timing, Color/B&W.

– Output sequence: High order 4 bits followed by lower order 4 bits

Y0h Y0l Y1h Y1l ...

U0h U0l V0h V0l ...

For B/W or one-line RGB raw data, the output data clock speed is doubled. For color YUV, output clock is four times that of the 16-bit output

data. In color mode, sensor must be set to 8-bit mode, and the nibble timing, clock divided by 2.

– Output sequence: U0h U0l Y0h Y0l V0h V0l Y1h Y1l ...
