Appeal No. 2002-1670
Application 08/768,787
The claimed invention relates to an image sensing method and
apparatus in which a determination is made as to whether a sensed
image is a black-and-white image or a color image. On
determination of a color image, a first pixel shifting procedure
is followed to sense a first number of plural images while, on
determination of a black-and-white image, a second pixel shifting
procedure for sensing a second number of plural images is
performed.
Claim 1 is illustrative of the invention and reads as
follows:
1. An image sensing apparatus having a color image sensor
and shifting means for shifting an image formation position on
said color image sensor, where said color image sensor senses an
image of an object formed at each image formation position
shifted by said shifting means, said apparatus comprising:
determination means for determining whether the object is a
color object for which a color image sensing operation is
suitable or the object is a black-and-white object for which a
black-and-white image sensing operation is suitable;
shifting control means for controlling said shifting means
to perform a first pixel shifting method so as to sense a first
number of plural images to be synthesized, in a first sequence in
a case where the object is a color object and to perform a second
pixel shifting method so as to sense a second number of plural
images to be synthesized, in a second sequence in a case where
the object is a black-and-white object in accordance with a
determination result by said determination means, wherein a set
of images sensed in the first pixel shifting method in said first
sequence is different from a set of images sensed in the second
pixel shifting method in said second sequence; and
