5.2.10. PIXCI® Image Viewer - Capture
The image viewer window associated with the PIXCI image board's frame buffer(s) has
Capture
which provides for capturing
images from the PIXCI imaging board and other features associated with the PIXCI imaging board. Any additional image viewer
windows created by
Launch 2nd Viewer
do not provide
Capture
, but only view, modify, examine, and/or draw the frame buffers.
The
Adjustments
allows setting common adjustments, as suitable for the model of the PIXCI imaging board in use. For example,
for PIXCI® SV2, SV3, SV4 and SV5 models, the
Adjustments
allows selecting the video input connection and adjusting the gain,
black level, hue, and saturation. Less frequently used, and more esoteric, adjustments may be found under
PIXCI® Video Setup
,
described above. A duplicate
Adjustments
is provided under
Image Viewer - View
.
The
Shortcuts
activates or deactivates the
PIXCI® Image Viewer - Capture - Shortcuts
, described below. A duplicate
Shortcuts
is
provided under
Image Viewer - View
.
The
Snap
captures and displays a single image. The
Live
continuously captures and displays images; the
UnLive
terminates the
Live
mode, displaying the last captured image.
The
First Buffer
switches to the first buffer of the frame buffer sequence, the
Last Buffer
switches to the last buffer of the frame
buffer sequence, the
Next Buffer
switches to the next buffer of the frame buffer sequence, and the.
Previous Buffer
switches to the
previous buffer of the frame buffer sequence.
The
GIO Event Capture
provides single or sequence image capture, each image triggered in conjunction with the imaging board's
general purpose (previously referred to as an external TTL) input and output signals. The XCAP-Lite version does not provide
the sequence option of the
GIO Event Capture
feature.
The
Sequence Capture
features allow capturing a timed sequence of images. The
Sequence Capture
features may be started by an
event (trigger), run continuously until stopped by an event, or each individual image captured in response to an event. Events
include mouse clicks, time of day, and the imaging board's general purpose (previously referred to as external TTL) inputs; when
used with general purpose input events the
Sequence Capture
differs from
GIO Event Capture
in that the latter provides more
options and higher accuracy and repeatability for the manipulation of the general purpose inputs and outputs in response to video
timing. former starts the entire sequence upon a single event (trigger), When recording at subvideo rates, a time stamp feature
allows recording the time that each image was captured, and either overlaying the time nondestructively or permanently marking
the image with the time.
A variety of
Sequence Capture
features provide tradeoffs between capture rate vs. convenience vs. total number of images
captured. The
Video to Frame Buffers
captures sequences directly into pre-configured frame buffer memory, and can support any
video rate or bandwidth. The
Video to Memory Buffers
captures and copies sequences into convenient dynamically allocated host
computer (virtual) memory, but may not support high video rate or bandwidth sequence capture for all cameras on all computers.
The
Video to Disk File
captures and copies sequences into a disk file in an efficient, internal format (after capture the sequence can
be saved in a standard format). The
Video to Image Files
captures and copies sequences directly into standard format image files,
but may not obtain as high video rate capture as the
Video to Disk File
feature. The XCAP-Lite version does not provide the
Video
to Image Files
or
Video to Disk File
features, or the time stamp feature, or the event (trigger) option of the
Video to Frame Buffers
or
Video to Memory Buffers
features.
The
Waterfall Display
displays a chosen line of the frame buffer, in a ''waterfall'' fashion, updating the screen once per field, or as
often as the host computer's speed allows. This feature is primarily intended for adjusting line scan type cameras. The waterfall
display is intended only for viewing; it can't be analyzed, and can be saved only as a side effect of
Screen Capture
.
The
Video to StreamStor
allows recording and playing video to and from Boulder Instruments StreamStor High-Speed Disk
Recorders, allowing recording at video rate with almost all cameras and resolutions. The
Video to StreamStor
is provided only in
the XCAP-Plus version.
The
RGB Merge
allows interpreting and viewing three monochromatic frame buffers as a single color (e.g. RGB) image, with
adjustments for registration and coloring. The XCAP-Lite version does not provide the
RGB Merge
feature.
The
Quad Pixel Merge
allows interpreting and viewing four monochromatic frame buffers, each one captured after shifting the
image sensor by ½ pixel horizontally and vertically, as a single high resolution image. The XCAP-Lite version does not provide
the
Quad Pixel Merge
feature.
The
Frame Average
allows performing recursive, continuous, averaging of live video frames (or fields) and viewing the live result.
The XCAP-Lite version does not provide the
Frame Average
feature.
The
Live Options
combines the
View - Display
options, above, with additional choices governing
Live
mode. During
Live
mode, the
PIXCI imaging board can, (a) Capture continuously into the specified frame buffer, however the image shown on the S/VGA may
contain portions from different video frames, (b) Snap, display to the S/VGA, and repeat, however the image display rate will be
slower, or (c) Alternate capturing into the specified frame buffer and the last frame buffer (dual buffering). On host computers
