Abstract:
1. An image sensing apparatus having an image sensing device which has a color filter including different first, second and third color components, said apparatus comprising: a reading device which sequentially reads a first field including the first and second color components and a second field including the second and third color components from the image sensing device by interlaced scanning in every one field interval; a storage device which stores an image signal output from said reading device; a controller which calculates a white balance coefficient on the basis of an image signal including the first and second color components read in the first field and stored in said storage device and an image signal including the second and third color components read in the second field, in parallel with reading operation of an image signal of the second field and after reading operation of the first field; and a white balance correction device which executes white balance correction to one frame image signal including the image signals of the first and second fields by using the white balance coefficient after the reading operation of the image signal of the second field from the image sensing device has been finished.
