Abstract
An image sensing device includes a pixel array including a plurality of image detection pixels structured to convert light incident onto the image detection pixels into pixel signals representing an image of an object, a plurality of phase-difference detection pixels in the pixel array structured to detect light from the object to generate a phase signal for measuring a distance between the image sensing device and the object, and a first lens positioned to direct light to the plurality of phase-difference detection pixels and including a plurality of portions each corresponding to at least one of the phase-difference detection pixels. A center of the first lens is located over a center of the plurality of phase-difference detection pixels, and each portion of the first lens extends from the center along a row or column direction between adjacent phase-difference detection pixels or along diagonal directions between the row and column directions.
