1. An image capture apparatus comprising: an image capture unit that captures a moving image and generates moving image data corresponding to a captured moving image; an instruction unit that instructs the image capture unit to capture a still image; an encryption unit that encrypts image data; a control unit that (a) controls the image capture unit to stop capturing a moving image if an instruction for capturing a still image is inputted while a moving image is captured, (b) controls the image capture unit to capture a still image after the instruction is inputted while a moving image is captured, (c) executes a first process of generating, based on still image data corresponding to a captured still image, predetermined moving image data, (d) controls the encryption unit to encrypt, based on a first encryption method, the still image data after the instruction is inputted while a moving image is captured, (e) executes a second process of determining whether the encryption unit needs to encrypt, based on a second encryption method, the predetermined moving image data after the instruction is inputted while a moving image is captured, and (f) controls, based on a result of the second process, an execution of an encryption for the predetermined moving image data, wherein the predetermined moving image data is related to a period where capturing a moving image is stopped.
