A medical processing device includes: an internal module configured to process a captured image obtained by imaging a subject and generates a display image; and a processor configured to control an operation of the internal module. The internal module is configured to perform, after an abnormality occurs in the processor, processing corresponding to a display mode designated by the processor before the abnormality occurs in the processor on the captured image.

Medical processing device, medical observation system, and medical device

A memory controller, in a first observation mode, writes a first captured image into a first memory area of a memory, reads first to fourth divided images obtained by dividing the first captured image from first to fourth divided areas of the first memory area, respectively, and outputs the first to fourth divided images to image processing unitsto, respectively, and in a second observation mode, writes the first and second captured images into second and third memory areas, respectively, each having the same memory capacity as that of each of the divided areas in the memory, respectively, reads the first and second captured images from the second and third memory areas, respectively, and outputs the first and second captured images to two image processing unitsand, respectively.

Medical image processing apparatus and medical observation system

A signal processing device includes a first internal modulethat executes hardware processing, and second internal modules that execute software processing. The first internal module outputs an image signal, division position information indicating division positions, at which a frame of the image signal is divided by a predetermined amount of data, and a timing signal, to the second internal modules, and generates, based on the image signal that has been subjected to the software processing and input from the second internal modules, a video signal for display. Based on the timing signal and the division position information, the second internal modules sequentially execute image processing by the software processing on the image signal per the predetermined amount of data, and sequentially output the image signal per the predetermined amount of data that has been subjected to the image processing, to the first internal module.
