Patent ID: 8760540

Claim:
An imaging device comprising: a lens unit which is detachably joined with a device body and comprises an optical lens, an image sensor capturing an optical image of a subject having transmitted through the optical lens and outputting an output signal, and an image processing unit executing a plurality of image processings on image data generated from the output signal of the image sensor; the device body which comprises a display unit displaying the image data, a storage unit storing an image file containing the image data and an image processing unit having a substantially same image processing function as that of the lens unit and executing a plurality of image processings on the image data; an allocating unit which changeably allocates the plurality of image processings to be executed on the image data to the image processing units of the lens unit and of the device body; and an interface connecting the lens unit and the device body for bi-directional communication, wherein the image processing unit of the lens unit performs the image processings based on setup data and operation data of the device body communicated via the interface; and wherein the image processing unit of the device body performs the image processings based on the setup data and operation data of the device body; and wherein when data on an operation mode contained in the setup data of the device body indicates a live view mode, the lens unit converts the captured subject image into compressed image data and then transfers the image data to the device body with a predetermined time interval, and the device body decompresses the compressed image data from the lens unit and outputs the decompressed image data to the display unit with a predetermined time interval.
