PHASE INFORMATION ACQUISITION APPARATUS AND IMAGING SYSTEM |
| 摘要 |
A phase information acquisition apparatus that acquires phase information from differential phase information on an object, includes: a differential phase acquisition unit that acquires differential phase information with respect to a plurality of directions; a weight setting unit that individually sets weights for the differential phase information of the respective directions; and a phase acquisition unit that determines phase information, using an equation that includes a weighted combination of the differential phase information of the respective directions with the weights of the respective directions set by the weight setting unit. |
