1. An image sensing apparatus comprising: a setting unit configured to set one of a plurality of image sensing modes; an image sensing unit configured to obtain an image of an object; a processing unit configured to perform image processing on the image obtained by the image sensing unit based on the image sensing mode set by the setting unit, the image processing including a plurality of processes; a communication unit configured to communicate with an external apparatus; and a determination unit configured to determine, based on the image sensing mode set by the setting unit, which of the image sensing apparatus and the external apparatus is to perform a predetermined process out of the plurality of processes on the image obtained by the image sensing unit, wherein in a case that the determination unit determines that the image sensing apparatus is to perform the predetermined process, the processing unit performs the predetermined process on the image obtained by the image sensing unit, and wherein in a case that the determination unit determines that the external apparatus is to perform the predetermined process, the communication unit transmits the image obtained by the image sensing unit to the external apparatus so that the predetermined process is performed by the external apparatus.
