1. An image sensing device comprising:
an image pixel region including active pixels, each active pixel configured to include a photoelectric conversion element which generate an imaging pixel signal through a photoelectric conversion of incident light received by the active pixel; and
an optical black pixel region disposed separately from the image pixel region, and including a plurality of black pixels and a light blocking layer that blocks incident light from entering the black pixels, each black pixel configured to include a photoelectric conversion element that generate a black pixel signal for correcting an effect of a dark current,
wherein
the image pixel region includes a condensing lens layer configured to condense the incident light on to the active pixels in the image pixel region, and
the optical black pixel region includes a dispersion lens layer located over the plurality of black pixels and configured to disperse the incident light and a color filter layer disposed between the dispersion lens layer and the plurality of black pixels.
