Adjustment for output image of image data
An image processing method of processing an image data uses an image file. The image file includes the image data and image processing control information being used for processing the image data. The method includes the steps of: (a) determining a degree of auto adjustment for adjusting lightness and contrast of the image data according to lightness of a whole image expressed by the image data, based on the image processing control information; and (b) performing the auto adjustment based on the determination.
1. An image output apparatus for outputting an image using image data indicative of the image and associated photographing information set at a generation of the image data, wherein
the photographing information includes light metering mode information on a light metering mode, wherein
the image output apparatus comprising:
a picture quality adjusting unit that performs a picture quality adjustment on the image, the picture quality adjustment being for which a degree of an adjustment of lightness and contrast of a whole image is reduced based on the photographing information if the photographing information indicates that the light metering mode measures part of the image, the picture quality adjusting unit reducing a degree of the picture quality adjustment of the whole image so as to perform the picture quality adjustment without using the photographing information on a measured area in the case where the light metering mode is configured to measure a predetermined area of the image; and
an outputting unit that outputs an image adjusted by the picture quality adjusting unit.
2. The image output apparatus in accordance with claim 1 , wherein
the picture quality adjusting unit is configured to perform the picture quality adjustment including the lightness and contrast adjustment with a less degree of adjustment in response to the light metering mode information indicating that the light metering mode measures part of the image than a degree of adjustment in response to the light metering mode information other than the information indicating that the light metering mode measures part of the image.
3. The image output apparatus in accordance with claim 1 , wherein
the light metering mode information represents one of a plurality of metering methods including averaged metering, center-weighted metering, spot metering, multi-spot metering, divisional light metering, and partial light metering, and
the information indicating that the light metering mode measures part of the image is information indicating spot metering, multi-spot metering, divisional light metering, and partial light metering.
4. An image output method of outputting an image using image data indicative of the image and associated photographing information set at a generation of the image data, wherein
the photographing information includes light metering mode information on a light metering mode, wherein
the image output method comprising:
performing a picture quality adjustment on the image, the picture quality adjustment being for which a degree of an adjustment of lightness and contrast of a whole image is reduced based on the photographing information if the photographing information indicates that the light metering mode measures part of the image, the picture quality adjustment being performed so that a degree of the picture quality adjustment of the whole image is reduced without using the photographing information on a measured area in the case where the light metering mode is configured to measure a predetermined area of the image; and
outputting an image adjusted by the picture quality adjustment.
5. A computer program product for causing a computer to output an image using image data indicative of the image and associated photographing information set at a generation of the image data, wherein
the photographing information includes light metering mode information on a light metering mode, wherein
the computer program product comprising:
a non-transitory computer readable medium; and
a computer program stored on the non-transitory computer readable medium, wherein
the computer program causing the computer to perform functions of:
performing a picture quality adjustment on the image, the picture quality adjustment being for which a degree of an adjustment of lightness and contrast of a whole image is reduced based on the photographing information if the photographing information indicates that the light metering mode measures part of the image, the picture quality adjustment being performed so that a degree of the picture quality adjustment of the whole image is reduced without using the photographing information on a measured area in the case where the light metering mode is configured to measure a predetermined area of the image; and
outputting an image adjusted by the picture quality adjustment.
