CINEMA EOS
|
A variety of corrections and adjustments are applied to these sampled images A and B to aid the precision of the detection depending upon lens settings. The results are sent to a microcomputer that makes the calculations for the requisite correction signal.

Displaying Onscreen Markers, Zebra Patterns and False Color with EOS C700 models
|
Using the False Color Display The false color display is an assistance display mode that turns the image from the camera to black and white and overlays on it 6 different colors to indicate important brightness ranges.

CINEMA EOS
|
The discussions in the White Paper (Deep Dive Part 1 ) centered about the all -important linear representation of the camera video. Now that video must be further “prepped” in a manner that can help ensure that the extensive dynamic range created by the imaging system will be fully protected while being recorded – and also as it is transported over industry standardized interfaces. This is the primary role of the camera’s Optoelectronic Transfer Function (OETF).

CINEMA EOS

This control is shared between an analog control (controlling the gain of the column amplifier within the CMOS image sensor [ 7 ] ) and a downstream digital control. In the case of the on -board recorded signals both controls are used. For the 4K RAW signal the analog control within the image sensor is progressively stepped up from ISO 800 to ISO 25,600 – with the separate digital settings sent as metadata that implements this control in postproduction.

Adjusting the Focus on EOS C700 models
|
Adjusting the Focus Manual focus: Turn the focus ring on the lens to adjust the focus. The camera offers several focus assistance functions to help you focus more accurately when using the manual focus.

Applying a LUT to Video Outputs
|
Applying a LUT to Video Outputs terminals or HDMI OUT terminal. When a LUTis applied, the displayed image will look as if a standard gamma curve and color space were used, making it easier to check the image on the monitoring device used. To check the image on an external monitor, you will need a monitor that is compatible with the selected color space.
