Claims

An image processing apparatus,
An analysis unit for analyzing image data;
A user interface control unit for displaying a setting screen capable of setting a control parameter used for image adjustment of the image data, and determining the control parameter according to the setting in the setting screen;
An image adjustment unit that performs the image adjustment on the image data using the determined control parameter;
A storage unit for storing relationship information representing a correspondence relationship between the analysis result of the image data by the analysis unit and the setting of the control parameter;
With
The user interface controller is
Correcting the relationship information by utilizing the analysis result of one or more target image data and the setting of the control parameter set on the setting screen for each target image data;
An initial setting of the control parameter displayed on the setting screen for new target image data is determined using the analysis result of the new target image data and the modified relationship information.
Image processing device.

The image processing apparatus according to claim 1,
The control parameter indicates the degree of the image adjustment,
The correction of the relationship information is executed such that the degree of image adjustment associated with the analysis result of each target image data by the relationship information approaches the degree of image adjustment set on the setting screen.
Image processing device.

The image processing apparatus according to claim 2,
The analysis result includes at least one feature amount obtained by analyzing the image data,
The relationship information is a look-up table including a plurality of lattice points indicating a correspondence relationship between the feature amount and the degree of image adjustment.
Image processing device.

The image processing apparatus according to claim 3,
The correction of the relationship information includes a first correction mode,
In the first correction mode, a reference point indicating a correspondence relationship between the feature amount indicated by the analysis result of the target image data and the degree of image adjustment set on the setting screen is added to the lookup table. To be
Image processing device.

The image processing apparatus according to claim 3 or 4, wherein:
The correction of the relationship information includes a second correction mode,
In the second correction mode,
(A) a reference point indicating a correspondence relationship between the feature amount indicated by the analysis result of the target image data and the degree of image adjustment set on the setting screen, and a part of the lattice points in the plurality of lattice points And a representative reference point is calculated by using
(B) From the lookup table, at least a part of the grid points used for calculating the representative reference point is deleted,
