| 摘要 |
The present invention provides a camera data transfer system comprising an imaging means for generating image data and outputting the same, and a camera interface means including a first holding means for holding one frame-preceding image data, a second holding means for holding the present image data, a comparing means for comparing the contents of the first and second holding means, and a bus interface means for controlling the input/output of data to and from a bus. In the camera data transfer system, the data is transferred to a frame memory of a display means connected to the bus through the bus interface means to cause the frame memory to display the data thereon. Further, when the data held in the first holding means and the data held in the second holding means are found not to coincide with each other as the result of comparison by the comparing means, only a place corresponding to the inconsistent data is transferred to the frame memory of the display means, and the data at the corresponding place of the first holding means is rewritten.
