Hereinafter, a detailed configuration of the control unit 9 will be described. The control unit 9 has a parameter control unit 9a, a shooting control unit 9b, and a display control unit 9c.
The parameter control unit 9a sets a shooting parameter of the imaging unit 2 according an instruction signal input from the first operating unit 3 or second operating unit 4a. Specifically, the parameter control unit 9a changes ISO sensitivity of the imaging unit 2, when an instruction signal that changes the ISO sensitivity is input from the first operating unit 3. Further, the parameter control unit 9a performs allocation to the first operating unit 3 and second operating unit 4a, based on setting signals for setting shooting functions of the first operating unit 3 and second operating unit 4a respectively from the change instruction unit 5.
Further, the parameter control unit 9a switches over the shooting function allocated to the first operating unit 3, if the 1st is input from the release switch 4b (if pressed halfway). Specifically, the parameter control unit 9a switches over the shooting function allocated to the first operating unit 3 to a shooting function that is able to conform to a change in a shooting condition of a subject, if the 1st is input from the release switch 4b (if pressed halfway). For example, if the 1st is input from the release switch 4b, the parameter control unit 9a refers to priority information recorded in the priority information recording unit 7a and switches over the shooting functions allocated to the first operating unit 3 and second operating unit 4a to shooting functions having shooting parameters of high priorities in a finished result of an image corresponding to image data, for example, to a shooting function that is able to change exposure compensation.
The shooting control unit 9b performs control to start a shooting operation in the imaging apparatus 1 with shooting parameter set by the parameter control unit 9a Specifically, if the 1st is input from the release switch 4b, the shooting control unit 9b causes the imaging apparatus 1 to execute the shooting preparation operation, and if the 2nd is input from the release switch 4b, the shooting control unit 9b causes the imaging apparatus 1 to execute the shooting operation with the shooting parameter set by the parameter control unit 9a. This shooting preparation operation refers to an operation of fixing a photometric value and/or a focal position of the imaging apparatus 1 by performing an automatic exposure process (hereinafter, referred to as “AE process”) of automatically determining an exposure value of the imaging apparatus 1 and an automatic focus adjustment process (hereinafter, referred to as “AF process”) of automatically determining a focus of the imaging apparatus 1. Further, the shooting operation refers to an operation of performing predetermined processing, for example, image processing including development processing, and compression processing, on the image data generated by the imaging unit 2, and recording them in the recording medium 8.
The display control unit 9c causes the display unit 6 to display an image corresponding to the image data generated by the imaging unit 2. Specifically, the display control unit 9c causes the display unit 6 to display, along a time series, the live view images corresponding to the image data continuously generated by the imaging unit 2. Further, the display control unit 9c causes the display unit 6 to display information related to the shooting functions allocated to the first operating unit 3 and second operating unit 4a, the information having been superimposed on the live view images.

If the control unit 9 determines that the change signal that changes the setting of the allocation of the respective shooting functions of the first operating unit 3 and the second operating unit 4a of the release mechanism 4 has been input from the change instruction unit 5 (step S104: Yes), the imaging apparatus 1 proceeds to later described step S105. In contrast, if the control unit 9 determines that the change signal that changes the setting of the allocation of the respective shooting functions of the first operating unit 3 and second operating unit 4a of the release mechanism 4 has not been input from the change instruction unit 5 (step S104: No), the imaging apparatus 1 proceeds to later described step S106.
At step S105, the parameter control unit 9a switches over the shooting functions allocated respectively to the first operating unit 3 and second operating unit 4a to shooting functions corresponding to the change signal input from the change instruction unit 5.

For example, as illustrated in
Thereafter, if the release switch 4b is pressed halfway by the user (step S107: Yes), the shooting control unit 9b executes each of the AE process and AF process (step S108). When this is done, the shooting control unit 9b fixes a photometric value by the AE process and a focal position by the AF process.
Subsequently, the imaging apparatus 1 executes the shooting parameter setting receiving process (step S109). The details of the shooting parameter setting change receiving process will be described later.
Thereafter, if the release switch 4b is fully pressed by the user (step S110: Yes), the shooting control unit 9b performs shooting according to the set shooting parameter set by the parameter control unit 9a (step S111).
Subsequently, if ending is performed by a power switch (not illustrated) being manipulated and the power of the imaging apparatus 1 being turned OFF (step S112: Yes), the imaging apparatus 1 ends this process. On the contrary, if the power switch (not illustrated) is not manipulated and ending is not performed (step S112: No), the imaging apparatus 1 returns to step S101.
At step S107, if the release switch 4b has not been pressed halfway by the user (step S107: No), the imaging apparatus 1 returns to step S101.
At step S110, if the release switch 4b has not been fully pressed by the user (step S110: No), the imaging apparatus 1 returns to step S101.
At step S101, if the imaging apparatus 1 has not been set to a shooting mode (step S101: No) and the imaging apparatus 1 has been set to a playback mode (step S113: Yes), the display control unit 9c executes a playback display process of causing the display unit 6 to display the image corresponding to the image data recorded in the recording medium 8 (step S114). After step S114, the imaging apparatus 1 proceeds to step S112.
At step S101, if the imaging apparatus 1 has not been set to the shooting mode (step S101: No) and the imaging apparatus 1 has not been set to the playback mode (step S113: No), the imaging apparatus 1 proceeds to step S112.

According to the above described first embodiment of the present invention, if the 1st is input from the release switch 4b, the parameter control unit 9a switches over the shooting function that has been allocated to the first operating unit 3. Thereby, picture forming conforming to the change in the shooting condition of the subject upon shooting is possible.
Further, according to the first embodiment of the present invention, since the parameter control unit 9a switches over the shooting function of the first operating unit 3 after the imaging apparatus 1 has fixed the focal position and photometric value with respect to the subject, it is possible to shoot something for which finishing of picture forming of the image has been further performed from the state in which the composition of the subject has been determined.
