Zoom
This pull-down menu allows the user to change the resolution (in pixels) of the
video output. Zoom factors of 0.5 and 0.625 will digitally average the pixel data to
give a lower resolution image. Zoom factors of 2, 4, and 8 will interpolate the pixel
data to give a higher resolution image. The maximum output size is 2560 x 2048.
Flip
This button allows the user to flip the image along its vertical axis to make it
appear like a mirror image. This feature can be used to compensate for capturing
a reflected image.
Video Mode
This window allows the user to control the video settings for the MicroVista
®
camera. See Figure 10: Video Mode Tab.

Video Mode
This section is used to define the sensor used for video output. The MicroVista
®
operates in two modes: Rolling Shutter, and Pseudo-Snapshot.
Rolling
Shutter
In Rolling Shutter mode, the camera accepts a user requested
frame rate, and adjusts the interline delay time to achieve that
frame rate. This allows the camera AGC (auto-exposure control)
to operate regardless of the frame rate, but exaggerates the
motion artifacts associated with rolling shutter CMOS devices.
Pseudo-
Snapshot
In Pseudo-Snapshot mode, the camera accepts an exposure
time, and adjusts the inter-frame delay to achieve that exposure
time. If the exposure time is less than the frame readout time,
then the camera adjusts the intra-frame integration time.
