| 1. An electronic image pickup system, characterized by comprising:
a phototaking optical system on which a light beam from an object is incident,
a color filter for splitting a, light, beam passing through the phototaking optical system into a plurality of colors,
an electronic image pickup device for sensing a light beam upon passing through the color filter, and
a color running correction means for reducing a color running that occurs at a brightness boundary in an output image from
an object image sensed by the electronic image pickup device and is included in the range defined by
0.25≤x≤0.65
0.465−0.076≤y≤0.25
as represented in terms of x-y chromaticity coordinates.
