Patent ID: 7477307

Claim:
An image conversion device configured to be connected to multiple image detection mechanisms, with each image detection mechanism generating and converting field image data to output an indication image data on one indication monitor, comprising: a plurality of input buffers corresponding to the image detection mechanisms, each of the input buffers having an input buffer input side and an input buffer output side, the input buffer input sides storing field image data from the image detection mechanism in one field units, and the input buffer output sides storing the field image data from the corresponding one of the image detection mechanisms that is moved from the input buffer input side to the input buffer output side when image storage operation on the input buffer input side has been completed; a plurality of output buffers with each of the output buffers having an output buffer input side and an output buffer output side, the output buffers storing the field image data in the input buffer output side after the field image data has undergone conversion processing, and moving the field image data to the output buffer output side after storage of the field image data on the output buffer input side has been completed; a pattern memory storing corresponding relationships of memory addresses of respective ones of the input buffer output sides of the input buffers and memory addresses of respective ones of the output buffer input sides of the output buffers; and an image conversion mechanism configured to perform the conversion processing in one field units by reading in the field image data stored in the input buffer output sides of the input buffers and writing into the output buffer input sides of the output buffers in accordance with the corresponding relationships of the pattern memory, when storage of the field image data has been completed in the output buffer input sides of the input buffers.
