What is the test for reversing a conviction for false imprisonment for insufficient evidence?

Because insufficient evidence supported appellant's felony convictions, we must modify the judgment to reduce those felony counts to misdemeanors and remand for resentencing. (See 1181, subd. (6) ["[I]f the evidence shows the defendant to be not guilty of the degree of the crime of which he was convicted, but guilty of a lesser degree thereof, or of a lesser crime included therein, the court may modify the verdict, finding or judgment accordingly without granting or ordering a new trial, and this power shall extend to any court to which the cause may be appealed."]; People v. Matian (1995) 35 Cal.App.4th 480, 487 [reversing felony false imprisonment for insufficient evidence and reducing offense to lesser included offense of misdemeanor false imprisonment].)
