The present disclosure relates to an image processing apparatus, an image processing method, and a program capable of realizing highly accurate image recognition processing while taking privacy into consideration with a simple configuration. A mask of a lensless camera is convoluted with a weight of a DNN first layer used in image recognition processing using a DNN, and a reconstructed image becomes a processing result of the DNN first layer on the basis of a captured image captured by an image sensor. Accordingly, the restored image becomes the processing result of the DNN first layer and becomes an image difficult for a person to visually recognize as a scene or an object, making it possible to protect the privacy of the image. The present disclosure can be applied to an image recognition apparatus using a lensless camera.
