BVM Series
Signal Analyzing Functions
Picture & Picture
The unique Picture & Picture function of the BVM-E and BVM-F Series allows simultaneous display of two input signals on the
monitor's screen. This function is extremely convenient for making instant adjustments to two input sources, because there is no
need to individually adjust the different characteristics of two monitors.
This function comes in handy for adjustments between two cameras, special-effects creation, time-lapse shooting, and
computer graphics (CG) work. The BVM-E Series offers four Picture & Picture modes and the BVM-F Series offers a side-by-side
The two picture images are downscaled using a
digital filter and displayed side-by-side. This feature is
convenient when making white balance adjustments or
determining shooting angles between two cameras.
Butterfly (BVM-E Series only)
The two inputs are displayed as line-symmetric images on the
left and right halves of the screen. By adjusting the H-position
controller, the two images can be moved inward to the
middle of the screen. An instant comparison of the moving
images can then be made easily and accurately, without the
user having to move their eyes.
Pixel Zoom
Pixel Zoom is a function for magnifying images. A selected
area of the displayed picture can be enlarged on a pixel
basis, up to eight times in size both vertically and horizontally.
Because this function does not use scaling, the desired
picture content is magnified and displayed faithfully to the
raw input signal. This function is useful when evaluating
precise picture edges, such as for chroma keying.
* This function is effective when the input signal is displayed in "Native Scan"
WIPE (BVM-E Series only)
The area of the two pictures to be displayed is selected using
a vertical WIPE pattern, which is controlled from the BKM-16R.
This function is useful when picture detail of the two images
must be examined on a pixel basis. This is normally used to
review still images.
Blending (BVM-E Series only)
The two picture images are overlapped for display, and the
mix ratio is adjustable. This function is useful to verify whether
a foreground signal is accurately keyed into the background
signal, or when combining shoots with live action and
computer-generated effects.
