Color Performance


Available for both SDI and HDMI

The waveform is a pattern to measure and display the brightness and its distribution (in false color) of every column of the input video, separates the Y, Cb, Cr, R, G, B channels, parade display or full scale display.
The waveform graticule marks the Luma value percentages. The Luma is pure black to pure white from bottom to the top, and the 100% full lines stands for the broadcast standard highest Luma value, while the real highest Luma value (pure white) is marked as 108% dash line on the top. The waveform pattern between 100% and 108% lines are considered as over exposed according to the broadcast standard.
The waveforms are real-time displayed, one-button switch on or off. There¨re totally 8 display modes of waveforms, and menu system can memorize the resent used mode to switch on, also you can change other modes easily in the waveform menu.

Vector Scope

Available for both SDI and HDMI

The vector scope pattern is to visualize the chrominance of input video signal by the distribution of color in the image on a circular scale. It represents saturation as distance from the center of the circle, and hue as the angle, in standard position around it. So you can see how saturated the image is and where the pixels in the image land on the color spectrum.
The vector scope pattern is divided into 6 districts, and stands for Red, Magenta, Blue, Cyan, Green and Yellow in different directions. The larger box stands for the color in 100% colorbar, and the smaller box stands for 75% colorbar.

R/G/B Histogram

Available for both SDI and HDMI

The histogram is a bar graph that shows the distribution of R / G / B values in the image. Similar as the Luma waveform pattern, the histogram is takes broadcast standard safety highest value as 100%, and 107% as the real highest value. The R / G / B distributions between 100% and 107% are considered as ineffective values in broadcast standard.




SDI Timecode Display

Under SDI input, the monitor can display the embedded SMPTE timecode (VITC1, VITC2 or LTC), which is used extensively for synchronization, and for logging and identifying material in recorded media.

Real Time 2-step Zoom-in

The first step zoom-in function is specially designed for Canon DSLR, to cut the black bar around the HDMI output video, and enlarge the center effective recorded video to full screen.
The second step zoom-in is to enlarge the video 4 times, to check the image details and help to focus.
The zoom-in function is real time operation, available when preview, recording or play back.

Peaking Focus Assist

The peaking focus assist function is to sketch out the sharpest edges of the image, for cameramen to check if the subjects are in focus. You can switch the outline color between blue and red according to different tone of the subjects. The peaking focus assist is also available during video zoom-in.




False Color

The false color is used to aid in the setting of camera exposure. Under false color mode, there¨s a color chart on the bottom of screen for reference. The over exposed subjects (above 101 IRE) on the monitor will display as RED, and the underexposed subjects will display as BLUE. For correct exposed subjects, it will display as green and pink.

Zebra Stripes

Like most professional cameras have, the zebra stripes are a warning to the over exposed areas of the image. When Luma value is over 90%, it is considered overexposed and displays the moving warning lines onto the over exposed areas.




Blue Only

Blue only is an assistant function to adjust camera color settings. Under the blue only mode, only the blue pixels are used to generate the image, because hue and saturation can be adjusted more quickly and accurately in this environment.

TALLY and RS485 Connection

The front TALLY light can display red, green and yellow colors, and input controlling signals via DB9 port. And TSL control signal is input via the DB9 port as well. The terminal description is as follows:


Connect R with GND: Display Red
Connect G with GND: Display Green
Connect Y with GND: Display Yellow
485A & 485B: for TSL 3.1/4.0 connection
