1. A device with image acquisition, the device comprising:
a first phase mask disposed above a display layer, where the first phase mask includes a first optical element configured to modulate external light;
the display layer comprising pixel areas between hole areas through which the modulated light passes, the pixel areas being configured to output a display image;
a second phase mask disposed below the display layer, where the second phase mask includes a second optical element configured to further modulate the modulated external light that is incident from the display layer after having passed through the first the hole areas;
an image sensor disposed below the second phase mask and configured to generate a raw image by sensing the further modulated external light; and
a processor configured to perform image processing on the raw image, based on blur information corresponding to the raw image.
