1. An apparatus comprising:
one or more processors; and
at least one memory coupled to the one or more processors storing instructions that,
when executed by the one or more processors, cause the one or more processors to function as:
a first acquisition unit configured to acquire RAW image data captured by a first device and captured image data captured by a second device;
an estimation unit configured to estimate a parameter of the first device by using a learning model that has learned a correspondence relationship between a parameter used to develop RAW image data and an image developed using the parameter such that characteristics of a developed image of the RAW image data are close to characteristics of the captured image; and
a development unit configured to develop the RAW image data by using the parameter of the first device,
wherein the learning model is a model generated for each of items of parameters used by the estimation unit.
