(Step S203). When it is determined that the reproduction flag is 1 (step S203: YES), the control unit 20 refers to the reproduction speed data, and reads the compressed moving image data and audio data from the recording medium A according to the reproduction speed. (Step S204), the read moving image data and audio data are decompressed by the compression / decompression unit 25b (Step S205).

  Then, the control unit 20 performs image processing on the expanded moving image data based on the enlargement ratio data, that is, processing for generating moving image data for enlarging or reducing the moving image and displaying the moving image data on the display unit 40. The moving image data is converted into a display signal and output to the display unit 40 (step S206). The display unit 40 displays a moving image based on the moving image data output from the video controller 25c. The control unit 20 converts the expanded audio data into an analog audio signal, amplifies the converted audio signal with an amplification factor according to the value of the volume data, and outputs the amplified audio signal to the speaker 7 (step S207). The speaker 7 reproduces sound based on the sound signal output from the signal processing unit 23.

  When the process of step S207 is completed, or when it is determined in step S203 that the regeneration flag is not 1 (step S203: NO), the control unit 20 calls a subroutine related to the adjustment of the adjustment target related to the reproduction, and sets the adjustment target. The adjustment process is executed (step S208).

Then, it is determined whether or not the reproduction mode is set (step S211). When it determines with it being in reproduction | regeneration mode (step S211: YES), the control part 20 returns a process to step S201. When it determines with not being in reproduction | regeneration mode (step S211: NO), the control part 20 sets 0 of an initial value to a reproduction | regeneration flag (step S212). Then, the control unit 20 sets the initial value 1 to the reproduction speed data and the enlargement ratio data (step S213), and finishes the subroutine processing relating to the reproduction of the moving image.

  FIG. 7 is a flowchart illustrating a processing procedure of a subroutine related to adjustment of an adjustment target. In step S208, when a subroutine related to adjustment is called, the control unit 20 detects the operation state of the first operation unit 5f and determines whether or not the displacement member 50f is displaced from the center (step S301). ).
