2.1 IMAGE RESOLUTION
The image resolution is determined by the number of pixels per line and number of lines
per frame. The image is framed by two signals LVAL, enveloping the valid pixels in a line,
and FVAL – enveloping the valid lines in a frame. The camera offers two independently
selectable LVAL and FVAL sizes. The first LVAL value envelops all visible pixels in a
line (active pixels plus buffer pixels) and the second – only the active pixels. Respectively,
the first FVAL envelops all visible lines in a frame (active lines and buffer lines), and the
second – only the active lines. The camera speed (Frames per Second) is the same for both
image size selections. Typically, the pixels outside of LVAL and FVAL (primarily dark
pixels and lines) are masked with zeros, but in BOBCAT, the user has an option to mask or
not to mask these pixels or lines. Refer to section “BOBCAT Configuration” for more
information.
Camera models B0610, B1410and B1610 are available only with a single output. Models
B0620, B1620 and B1920 are available in single or dual, and B2520 is available only with
dual output. In some camera models a high readout mode is available as described below.

Normal Mode – Single Output
When operating in the single output mode, all pixels are shifted out of the HCCD
register towards the left video amplifier – Video L (Figure 2.1). The resulting image
has a normal orientation.
