ABSTRACT:
An image processor is disclosed which is capable of automatically generating a series of test signals, running the test signals through its image processing software and hardware, and capturing the resulting output signals to automatically generate a 3D LUT that represents most or all of the imaging processing steps being performed by the image processor. No external equipment is required to generate the 3D LUT. In other embodiments, the image processor may be connected to an external image processing device, and the image processor can then automatically generate a series of test signals, run those test signals through the external image processing device, and capture the resulting output signals to automatically generate a 3D LUT that represents most of all of the image processing steps being performed by the external image processing device.
