An image processing apparatus includes a moving image generating unit configured to generate moving image data, an instructions providing unit configured to set a frame rate of the moving image data and provide instructions to change a frame rate to the set frame rate, a control unit configured to control the moving image generating unit to generate moving image data of the frame rate set by the instructions providing unit, an additional information generating unit configured to generate additional information indicating a change of the frame rate of the moving image data in response to the instructions to change the frame rate, and a transmitting unit configured to transmit the moving image data generated by the moving image generating unit and the additional information. The transmitting unit transmits the additional information before a frame rate change point in the moving image data.
