Abstract
An image data processing system can include one or more processors, a first video output port, and a second video output port. The one or more processors can: receive an encoded stream of digital motion picture image data encoded using an encoding function; generate a first monitoring data stream from the encoded stream using a first decoding function, the first monitoring data stream including first image data; and generate a second monitoring data stream from the encoded stream using a second decoding function different from the first decoding function, the second monitoring data stream including second image data having a narrower brightness range than the first image data. The first and second video output ports can output the first and second monitoring data streams for display in parallel.

An image data processing system comprising:
- a camera housing containing an image sensor configured to convert light incident on the image sensor into sensor data;
- one or more processors configured to:
- encode, using an encoding function, a stream of digital motion picture image data derived from the sensor data to obtain an encoded stream,
- generate a first monitoring data stream from the encoded stream using a first decoding function, the first monitoring data stream comprising first image data, and
- generate a second monitoring data stream from the encoded stream using a second decoding function different from the first decoding function so that second image data of the second monitoring data stream has a narrower brightness range than the first image data;
- and
- a first video output port and a second video output port in communication with the one or more processors, the first video output port and the second video output port being configured to simultaneously output the first monitoring data stream and the second monitoring data stream to a plurality of displays to permit a user to live monitor video captured using the image sensor,
- wherein the second decoding function is configured to, for tones brighter than middle grey, diminish highlights in the encoded stream more than the first decoding function.
