1. An image sensing apparatus for electronically applying shake correction to sensed image data by changing a read position of the sensed image data at said image sensing apparatus, and outputting corrected image data, comprising:
shake detection means for detecting a shake;
sampling means capable of sampling shake information detected by said shake detection means at a plurality of sampling timings within one field period of said image sensing apparatus, wherein the one field period defines an accumulation time period of said image sensing apparatus;
selection means for selecting a shake information signal at one of the plurality of sampling timings, which corresponds to a drive condition of image sensing means at the time of image sensing;
correction data calculation means for calculating a shake correction data used in the shake correction by a predetermined calculation of the shake information signal selected by said selection means; and
correction means for applying the shake correction to the sensed image data in accordance with the obtained shake correction data,
wherein an operation phase of said sampling means is variable within a sampling interval.
