Adjustment for output image of image data
The present invention is an image processing method of processing an image data using an image file. The image file includes the image data and image processing control information being used for processing the image data. The method comprises 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 whole image is reduced based on the photographing information if the photographing information indicates that the light metering mode measures part of the image; and
an outputting unit that outputs an image adjusted by the picture quality adjusting unit,
wherein the picture quality adjusting unit is configured to perform the picture quality adjustment without the lightness and contrast adjustment if the photographing information indicates that the light metering mode measures part of the image.
2. 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 whole image is reduced based on the photographing information if the photographing information indicates that the light metering mode measures part of the image; and
an outputting unit that outputs an image adjusted by the picture quality adjusting unit, 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,
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, and
the picture quality adjusting unit is configured to provide a user interface for allowing a user to adjust the degree of lightness and contrast adjustment if the light metering mode information indicates the center-weighted metering.
