Final answer:
Automatic rescaling is the process that compensates for incorrect exposure settings in digital imaging, allowing the image to appear diagnostic.
Step-by-step explanation:
When the wrong technical factors are selected in digital imaging, the process that allows the image to appear diagnostic is automatic rescaling. This process adjusts the brightness and contrast of the digital image, compensating for underexposure or overexposure. Automatic rescaling ensures that the grayscale values of an image fall within a visible and appropriate range. While histogram analysis also plays a part in processing the image by determining the range of grayscale values, it does not modify the image data to ensure diagnostic quality. Edge enhancement and windowing are other post-processing techniques but they are not responsible for correcting the overall exposure level of the image.
