Abstract:
1. An image sensing apparatus comprising: an image sensing device for imaging a subject through a zoom lens, which is capable of optically scaling a light image, and outputting image data representing the image of the subject; an electronic zoom device for electronically scaling the image data obtained by said image sensing device; a zoom operating device for performing an operation for changing zoom magnification of the zoom lens and of said electronic zoom device; a zoom control device for scaling the image data using only the zoom lens if zoom magnification is within an optical-zoom application scaling range that extends up to a maximum optical zoom magnification which prevails when the zoom lens is situated at a telephoto end, and making joint use of said electronic zoom device if zoom magnification is within an electronic-zoom application scaling range that exceeds the maximum optical zoom magnification; a super-resolution processing device for subject the image data to super-resolution processing that emphasizes contours while suppressing emphasis of noise, thereby generating super-resolution image data; and a weighted combining device for combining the generated super-resolution image data and image data, which has not been subjected to super-resolution processing, by weighting processing executed such that the higher the zoom magnification, the greater the weight assigned to the super-resolution image data, this being performed when the zoom magnification is within the electronic-zoom application scaling range.
