AJ-GBX27
HD Gamma Corrector
Field mode corrects underexposed and low-contrast F.REC gamma
images, and outputs monitor images with full film texture that can be
used to check the lighting. There's a setting for ordinary daylight and one
for nighttime shooting.
Telecine mode is a post-processing mode that uses movie footage to
produce TV content with a film-like texture (a telecine look). This mode
preserves the high image quality by correcting intermediate gradation
while maintaining highlights and shadows.
The Video Rec and Video modes convert images with F.REC gamma
characteristics to V.REC gamma or video gamma characteristics.
CG mode is a film production mode that reverse-converts images into
F.REC images after they were previously converted to telecine mode and
CG-processed for production ease. Also provided is a user mode that lets
you install any desired conversion table from a PC.
In addition to 720p (59.94/60 Hz), the AJ-GBX27 is compatible with 1080i
(59.94/60/50 Hz) and 1080p (23.97/24/25 Hz) HD formats.* This makes it
ideal for AJ-HDC27H recording and for editing, package production, and
a host of other applications. The 12-VDC power supply (XLR 4-pin
terminal) lets you take the AJ-GBX27 into the field. One HD-SDI input,
two HD-SDI outputs, and an analogue HD (Y/Pb/Pr) output are provided
for convenient monitor connection. Make contacts let you control
conversion ON/OFF from a switcher.
*This is not a format conversion function. It allows input/output of the same format only.
