# Channel image output¶

## Description¶

Simulation results displaying illuminance in lux as a channel image

outputicon| The Channel image output displays a single channel as an image.

Ocean can display raw sensor values, but as the instrument characteristics are stored with the images, it can also compute radiometric or photometric quantities, depending on the instrument and sensor types. See quantities for more details. The values are then mapped to a selectable color gradient using linear or logarithmic scale, within the given range.

## Children Nodes¶

This node has a filter list. It may have a variable number of filter children. The name of each filter is user-defined and does not affect the result.
