As far as image encryption is concerned, correlation test is not sufficient. It is normally coupled with other tests, see an example of these tests in the paper:

Article A hash-based image encryption algorithm

Sudeept Singh Yadav

Correlation test is also a part of image encryption, we can also perform NPCR, UAIC and MSE test for image encryption.
