2.2 Image Formats

2.2.3
VGA Format
This is the default format and produces an output of 644 pixels by 484 pixels.
Sub-sampled QVGA format
In this mode the QVGA image is generated by sub-sampling the VGA image in groups of 4 to
preserve the Bayer pattern with every second group of pixels and lines skipped as illustrated in
Figure
address sequence is preserved. Due to the crude nature of the sub-sampling, the resultant output
image will be of inferior quality but contains full field of view and is intended as a preview option
before switching to view the required scene region in more detail.
Window Of Interest QVGA
In WOI mode the QVGA image is generated by cropping the VGA image. I2C registers 87, 88 and
90 allow the user to select the coordinate of the top left corner of the QVGA WOI within the VGA
picture (an offsetof (0,0) means top left of the full VGA array). The default frame rate in this modeis
twice that of the default VGA mode
row
8. Although the former would not necessarily apply to a monochrome sensor the same
