Method and apparatus with image quality improvement

A device with image acquisition, the device comprising:

• a display layer comprising hole areas through which external light passes and pixel areas between the hole areas;
• a multiple phase mask under the display layer and configured to diffuse the external light that has passed through the hole areas and to modulate the diffused light to correspond to the external light;
• and
• an image sensor under the multiple phase mask and configured to generate a raw image by sensing modulated light that has passed through the multiple phase mask.

A method with image acquisition, the method comprising:

• modulating, using a first phase mask disposed at a front end of a display layer, an external light;
• modulating, using a second phase mask disposed at a rear end of the display layer, the modulated light that has passed through the first phase mask;
• generating, using an image sensor disposed at a rear end of the second phase mask, a raw image by sensing the modulated light that has passed through the second phase mask;
• and
• performing, using a processor, image processing on the raw image, based on blur information corresponding to the raw image.
