| 1. An image input apparatus, comprising:
an image sensing device having pixels arranged in two dimensions;
a selector arranged to select a motion image mode of recording a motion image or a still image mode of recording a still image;
a driving circuit arranged to drive the image sensing device such that signals of first pixels included in a first region
of the image sensing device are read out in the motion image mode and signals of second pixels included in a second region
of the image sensing device are read out in the still image mode, wherein the second region is larger than the first region
and number of the second pixels is larger than number of the first pixels;
a signal processing circuit arranged to process signals read out from the image sensing device; and
a recording unit arranged to record signals processed by the signal processing circuit in a recording medium with a predetermined
format in the motion image mode,
wherein number of pixels of the image sensing device is larger than number of pixels which is defined by the predetermined
format, and
the driving circuit is further arranged to drive the image sensing device such that, in the motion image mode, the signals
of the first pixels are read out from the first region in a first vertical scanning period and, in the still image mode, the
signals of the second pixels are read out from the second region in a second vertical scanning period that is longer than
the first vertical scanning period.
