Abstract: The present disclosure relates to an image processing apparatus and method and an image processing system that enable highly accurate observation. An intra-frame operation unit performs, as online processing, image processing of speckles generated by irradiation with laser light on a captured image in accordance with a relationship between an image output frame rate and a sampling rate. A high-precision operation unit performs, as offline processing, the image processing of speckles on the captured image in accordance with the relationship between an image output frame rate and a sampling rate. The present disclosure may be applied to an image processing system including, for example, a speckle imaging apparatus.
