Method and apparatus for recording digital holographic portrait photograph using neural network image interpolation

An apparatus for recording a digital holographic portrait photograph, the apparatus comprising:

• a camera array including a plurality of cameras arranged at a variable rotation angle;
• at least one processor electrically connected to the camera array;
• and
• a memory storing instructions executable by the at least one processor,
• wherein the at least one processor, when executing the instructions, is configured to:
• perform a preliminary test using the camera array including a plurality of cameras arranged at a specific rotation angle;
• compare pixel colors between an acquired image and an actual image generated through the preliminary test;
• convert a color of an area in which a difference in pixel colors in the acquired image and the actual image is greater than or equal to a preset reference to a specific color;
• calculate an accuracy of the acquired image;
• determining the maximum allowable angle between two adjacent cameras in the plurality of cameras based on the area converted to the specific color and the accuracy;
• acquire a plurality of images using the camera array including a plurality of cameras arranged at the maximum allowable angle;
• and
• interpolate the plurality of images to record a holographic portrait photograph.
