8.1 VIDEO MODES
Despite being a linear camera, NECTA provides images (frames) consisting of multiple consecutive lines.
A frame is made of a programmable number of lines; both line length and line offset (the number of
pixels to skip from the rst effective pixel of the sensor) are programmable and specify the Region-Of-
Interest (ROI). Like area-scan cameras, NECTA acquires through video modes, that can be associated
with specic congurations (ROI, pixel format, line period, etc.). The desired video mode can be selected
through the VideoMode property:
Example Code 8.1 | Video mode conguration
device.VideoMode = 1; // Set Video Mode 1
Note
Video modes can be selected only when the camera is not acquiring.
8.1.1 Mode 0 (Normal)
Mode 0 is the most commonly used mode; it allows using all pixel formats (see Section 8.5) and makes
all processing chain controls available.
8.1.2 Mode 1 (RAW)
Mode 1 allows acquiring RAW data from the sensor, with no additional processing (available pixel for-
mats are RAW8 and RAW16 only). When in mode 1, the processing chain is disabled; this mode can
