ABSTRACT:
Disclosed is an image data compressing device for an endoscope which is for use in converting a plurality of color signals obtained by separating the image provided by the endoscope into electrical signals and then quantizing and storing the thus-obtained signals. The image data compressing device includes sampling means for conducting sampling at sampling intervals which are different for each of the plurality of color signals and which correspond to the characteristics of each of the plurality of colors in the image obtained by the endoscope, so as to enable the image data to be compressed in accordance with the characteristics of each of the colors of the image provided by the endoscope.
In consequence, data compression can be conducted without losing the quality of the image provided by the endoscope.
