Claim 15:
16. Non-transitory computer-readable storage medium storing instructions that cause a computer to at least perform a method for endoscopic imaging with an endoscopic imaging system, the endoscopic imaging system comprising a video endoscope having at least one CMOS image sensor, a light source configured to generate white light and at least one special light, and a controller, the method comprising:
capturing white light images with the video endoscope under white light illumination in a white light imaging mode;
evaluating the white light images captured in the white light imaging mode in real time by the controller to detect whether at least one structure having at least one predefined characteristic is present in the white light images captured in the white light imaging mode,
when the presence of the at least one structure having the at least one predefined characteristic is detected in at least one white light image of the evaluated white light images, switching from the white light imaging mode to a special light imaging mode in which the light source generates special light illumination other than white light imaging using the at least one special light and one or more images of a video stream are captured under the special light illumination and subjected to image processing in the special light processing mode;
identifying a subregion of the at least one white light image that contains the detected at least one structure with the predefined characteristic and reading out only a corresponding subregion of the image sensor, and
processing the image data read out from the corresponding subregion as one or more special light images.
