Claim:
An imaging apparatus comprising: an image capture unit; a generating unit that generates authentication data used to authenticate whether image data acquired by the image capture unit is altered; an instruction unit that issues an image capture instruction; a mode setting unit that sets an authentication data addition mode; a recording unit that records the image data acquired by the image capture unit and the authentication data generated by the generating unit in a removable recording medium, wherein the recording unit records the image data acquired by the image capture unit together with the authentication data in the removable recording medium in accordance with the image capture instruction issued by the instruction unit, if the authentication data addition mode is set by the mode setting unit, and records the image data acquired by the image capture unit without the authentication data in the removable recording medium in accordance with the image capture instruction issued by the instruction unit, if the authentication data addition mode is not set; a display unit; and a control unit that determines whether the authentication data addition mode is set by the mode setting unit in response to the image capture instruction issued by the instruction unit and controls the display unit so as to display an image relating to the image data which the image capture unit acquired in accordance with the image capture instruction and an additional information indicating that the authentication data is recorded with the image data in response to the image capture instruction, if it is determined that the authentication data addition mode is set by the mode setting unit, and the control unit controlling the display unit so as to display an image relating to the image data which the image capture unit acquired in accordance with the image capture instruction but not to display the additional information in response to the image capture instruction, if it is determined that the authentication data addition mode is not set, wherein, if it is determined that the authentication data addition mode is set by the mode setting unit, until the image data captured by the image capture unit is recorded by the recording unit from the image capture instruction had been issued by the instruction unit, said control unit controls the display unit so as to display the image relating to the image data captured by the image capture unit and the additional information.
