Abstract
According to one embodiment, there is provided an optical film with a recording surface, the recording surface including: a computation element section in which a phase component of light from each reconstruction point of a reconstructed image is computed, the computation element section corresponding to each reconstruction point one by one; a phase angle recording area in which a phase angle computed based on the phase component is recorded; and a phase angle non-recording area in which the phase angle is not recorded, the phase angle computed based on the phase component being recorded in an overlapping area where the computation element section and the phase angle recording area overlap each other.

An optical film with a recording surface, the recording surface comprising:
- a computation element section in which a phase component of light from each reconstruction point of a reconstructed image is computed, the computation element section corresponding to each reconstruction point one by one;
- a phase angle recording area in which a phase angle computed based on the phase component is recorded;
- and
- a phase angle non-recording area in which the phase angle is not recorded,
- the phase angle computed based on the phase component being recorded in an overlapping area where the computation element section and the phase angle recording area overlap each other.
