Medical image acquisition system and medical imaging device

A medical image acquisition system comprising:

• an imaging device configured to image a subject to generate an imaging signal;
• and
• an image processing device electrically and detachably connected to the imaging device and configured to process the received imaging signal from the connected imaging device to generate an image signal corresponding to the imaging signal,
• wherein the connected imaging device includes:
• an imaging sensing circuit configured to receive light and convert the light into an electric signal to generate the imaging signal;
• an optical mechanism including a focus mechanism moving one or a plurality of lenses to adjust a focal point position, and configured to form an optical image on the imaging sensing circuit;
• and
• a memory configured to store therein operating characteristic information unique to the imaging device,
• wherein the image processing device includes an auto focus evaluation circuit configured to perform focusing evaluation based on the imaging signal, and
• wherein the focus mechanism is configured to be driven based on the operating characteristic information in accordance with an evaluation result by the auto focus evaluation circuit of the connected image processing device.
