Abstract
An image processing device capable of executing adjustment of image quality of image data includes a feature amount obtainment unit which obtains an amount of feature indicative of a feature of image quality of the image data, a correction amount obtainment unit which obtains an amount of correction for adjusting the feature amount of the image data to a predetermined target value, and an image quality evaluation unit which evaluates an image quality based on the correction amount.
Claims6
An image processing device capable of executing adjustment of image quality of image data, comprising:
- a feature amount obtainment unit which obtains an amount of feature indicative of a feature of image quality of the image data;
- a correction amount obtainment unit which obtains an amount of correction for adjusting the feature amount of the image data to a predetermined target value;
- and
- an image quality evaluation unit which evaluates an image quality based on the correction amount
- wherein when a file group includes at least JPEG data and RAW data both derived from same image data, the feature amount obtainment unit obtains the feature amount based on the JPEG data, the image processing device further comprising a file selection unit which selects the JPEG data as a target to be output when a result of evaluation by the image quality evaluation unit is higher than a predetermined level, the file selection unit selecting the RAW data as the target to be output when the result of evaluation by the image quality evaluation unit is lower than the predetermined level.
An image processing device capable of executing adjustment of image quality of image data, comprising:
- a feature amount obtainment unit which obtains an amount of feature indicative of a feature of image quality of the image data;
- a correction amount obtainment unit which obtains an amount of correction for adjusting the feature amount of the image data to a predetermined target value;
- an image quality evaluation unit which evaluates an image quality based on the correction amount;
- and
- a user correction amount storage unit which stores a user amount of correction based on a result of retouch with the image data by the user and a target value modification unit which modifies the predetermined target value based on the user correction amount.
An image processing program embodied in a non-transitory computer readable medium which is capable of executing adjustment of image quality of image data and on which a computer executes functions of:
- obtaining an amount of feature indicative of a feature of image quality of the image data;
- obtaining an amount of correction in image quality adjustment based on comparison of the feature amount and a target image quality;
- and
- evaluating an image quality based on the correction amount,
- wherein when a file group includes at least JPEG data and RAW data both derived from same image data, the feature amount is obtained based on the JPEG data, the JPEG data is selected as a target to be output when a result of the image quality evaluation is higher than a predetermined level, and the RAW data is selected as the target to be output when the result of the image quality evaluation is lower than the predetermined level.
