  The RAM 13 appropriately stores data necessary for the CPU 11 to execute various processes.

  The CPU 11, ROM 12, and RAM 13 are connected to each other via a bus 14. An input / output interface 15 is also connected to the bus 14. An imaging unit 16, an input unit 17, an output unit 18, a storage unit 19, a communication unit 20, and a drive 21 are connected to the input / output interface 15.

  Although not shown, the imaging unit 16 includes an optical lens unit and an image sensor.

The optical lens unit is configured by a lens that collects light, for example, a focus lens or a zoom lens, in order to photograph a subject.
The focus lens is a lens that forms a subject image on the light receiving surface of the image sensor. The zoom lens is a lens that freely changes the focal length within a certain range.
The optical lens unit is also provided with a peripheral circuit for adjusting setting parameters such as focus, exposure, and white balance as necessary.

The image sensor includes a photoelectric conversion element, AFE (Analog Front End), and the like.
The photoelectric conversion element is composed of, for example, a CMOS (Complementary Metal Oxide Semiconductor) type photoelectric conversion element or the like. A subject image is incident on the photoelectric conversion element from the optical lens unit. Therefore, the photoelectric conversion element photoelectrically converts (captures) the subject image, accumulates the image signal for a predetermined time, and sequentially supplies the accumulated image signal as an analog signal to the AFE.
The AFE performs various signal processing such as A / D (Analog / Digital) conversion processing on the analog image signal. Through various signal processing, a digital signal is generated and output as an output signal of the imaging unit 16.

Is generated by performing image processing with a value having a different value (hereinafter referred to as a “bracket value”).
The reference value is configured to be adjustable by the user.
On the other hand, the bracket value is set according to the reference value without adjustment by the user. The bracket value is not a fixed value or number. For example, when the reference value is near the center of the settable range, the user intends to obtain a wide range of changes. If the number is close to the end of the settable range with a large number (e.g., 7 images, reference value 1 / bracket value 6), the user's intention is strong and weak. 3 sheets, the reference value 1 and the bracket value 2) can be made variable.

In the present embodiment, in more detail, the bracket value is defined as the reference value being the initial position (hereinafter, the reference value of the initial position is referred to as “initial reference value”) or adjusted by the user as the initial position.

The contents can be selected. In addition, “(D) bracket value setting direction” is “1: both sides of the reference value”, “2: one side of the reference value (+ direction)”, and “3: one side of the reference value (− direction). ) ”Is selectable.

  For example, make-up setting is bracket value setting condition: “(1): parameter value adjustable range” is “1: real number excluding negative number” and “(2) initial reference value” is “1: parameter value adjustment” “Other than the end of the possible range”, bracket value setting method: “(A): Bracket value setting method” is “1: Change both number and amount of change” • “(B) Number of bracket values “Change method” is “1: The number is decreased as the degree of divergence is larger”. “(C) The change method of bracket value change amount” is “1: The amount of change is increased as the degree of divergence is larger”.

In addition, when [reference value: 1] of [deviation from the initial reference value (difference): −6] where the difference from the initial reference value becomes the most negative side, [+ side bracket value: 2] ] Only.

In makeup setting example 5,
(1) Parameter value adjustable range is a real number excluding negative numbers (2) Initial reference value is the end of parameter value adjustable range [Initial reference value: 1]

Therefore, in the photographing apparatus 1, when performing make-up photographing, if it is desired to try changing settings depending on the photographing environment or the photographer's factors, it is possible to perform efficient photographing without repeating complicated operations. .

<Modification>
In the above-described embodiment, a plurality of captured images are generated by performing multiple times of image processing on a single captured image, but the bracket value, which is a combination of parameter values, is changed for each capture. Ordinary bracket shooting in which a plurality of shots are performed to generate a plurality of shot images may be used. Specifically, for example, normal bracket shooting in which the number of bracket shooting or the bracket value is changed according to the degree of deviation between the exposure correction value set by the user and the standard value presented by the apparatus may be used. .

FIG. 9 is a schematic diagram illustrating a setting example of exposure correction setting.
Specifically, in the exposure correction setting example, the bracket value setting condition and the bracket value setting method in FIG. 2 are (1) -2 (2) -1 (A) -1 (B) -1 (C) -1 ( D) -1 is adopted, for example, as shown in FIG.
(1) Parameter value adjustable range: real number (2) Initial reference value: Other than the end of parameter adjustable range: ± 0
(A) The bracket value setting method changes both the number and the amount of change (B) The method of changing the number of bracket values decreases the number as the degree of divergence increases (C) The method of changing the amount of change in the bracket value (D) Bracket value setting direction: Since it is on both sides of the reference value, the reference value is not adjusted by the user [Deviation degree from the initial reference value (difference ): ± 0] [reference value: ± 0] [+ side bracket value: +1/2, +3/2, +3] • [-side bracket value: -1/2, -3/2 , −3].
Further, when [reference value: 3] of [deviation from the initial reference value (difference): +3] where the difference from the adjustment reference value becomes the largest on the plus side, [−side bracket value: +5/2] ].

<Other variations>
In the embodiment described above, the degree of deviation between the adjustment reference value and the initial reference value is simply the difference between the initial reference value and the adjustment reference value moved by the user from the initial reference value [adjustment reference value−initial reference value]. However, for example, it can be configured as [(adjustment reference value) − (initial reference value) ^ 2] so as to emphasize the degree of deviation more. Further, when the minimum value is a positive number as in the makeup level described above, [(adjustment reference value) ^ 2- (initial reference value) ^ 2] is configured so that the degree of deviation is emphasized as the level is higher. be able to.

The photographing apparatus 1 configured as described above performs bracket photographing in which an image with one or a plurality of bracket values obtained by changing a parameter value based on a reference value of a predetermined parameter is acquired.
In addition, the photographing apparatus 1 includes a parameter setting unit 58.
The parameter setting unit 58 acquires an adjustment reference value that is adjusted by a user operation from an initial reference value that is initially set when bracket shooting is performed.
The parameter setting unit 58 calculates the degree of deviation between the acquired adjustment reference value and the initial reference value.
In addition, the parameter setting unit 58 sets a bracket value for performing bracket shooting based on the calculated deviation degree based on the adjustment reference value.
As a result, in the photographing apparatus 1, the bracket value is set based on the reference value (adjustment reference value) adjusted by the user's operation from the initial reference value when the bracket photographing is performed.
