Unity Depth Camera
You can define distance ranges by setting min and max values. Clamped distances are being mapped to the full 8-bit color range. Default depth values are flipped so that close objects are more saturated than farther-away ones.
Red channel only.
Green channel only with inverted depth values.
One color channel per distance range, increases the total depth resolution compared to using a single channel.
Blue channel limited to foreground, mixed with source image’s red and green channels.
All channels limited to foreground, inverted.
