User Manual

108 Camera Controls
Sensor mode Select to set which sensor mode is active: 16:9, 4:3, 6:5, or
Open Gate.
Note: Changing the sensor mode includes a factory reset.
Sensor tempera-
ture
Select to set the sensor temperature to Standard (default)
humidity or High humidity. When shooting in tropical condi-
tions with high temperature and high humidity, the sensor
temperature can be changed from Standard to High humid-
ity to prevent condensation from forming on the sensor cov-
erglass.
Noise reduction Select to set noise reduction On or Off.
Note:When recording ARRIRAW, noise reduction is only ap-
plied to the previewing paths and not to the recorded im-
ages. Information about noise reduction is stored in metada-
ta.
Note: Using noise reduction may result in slight image ar-
tifacts when capturing fast moving objects. As always, use
tests to verify applicability.
Image transform Select to set the desired image transformation. Available val-
ues are:
•
None
•
Mirror horiz.
•
Rotate 180°
Note: Horizontal mirroring is applied on all output paths and
internally recorded material. Image rotation is only applied to
output paths; internally recorded material is not rotated, but
rotation information is written into metadata. Frame grabs of
rotated images will be displayed upside down on a comput-
er.
User Pixel Mask-
ing
Select to open the User Pixel Masking screen.
User Pixel Masking
All sensors exhibit a certain number of defect pixels, and ALEXAs have two
mechanisms to catch and correct them: one is a static pixel correction based on a
pixel mask created during manufacturing, and the other is a dynamic pixel correction
that continuously evaluates each frame and masks defect pixels that are not caught
by the static pixel mask. In very few cases we have observed some pixels that are not
corrected by either method; for those cases we have developed User Pixel Masking.
