1. An image sensing device comprising:
a first pixel group including at least one first half-shading pixel and at least one first normal pixel; and
an image processor suitable for calculating a depth from a subject by using a first pixel signal, which is generated from the first half-shading pixel during a first period, as phase information, generating a high-illuminance image by using a first pixel signal, which is generated from the first half-shading pixel without using a normal pixel signal generated from the first normal pixel during a second period, as dynamic range information, generating a low-illuminance image by using the normal pixel signal generated from the first normal pixel without using the first pixel signal during the second period, and generating a high dynamic range image by synthesizing the high-illuminance image and the low-illuminance image,
wherein the first half-shading pixel and the first normal pixel are controlled to have the same integration time.
