Abstract

A decision as to whether to perform backlight adjustment processing is executed using both image data and image generation record information, and when it is decided to execute the same, backlight adjustment processing to increase brightness value of at least some pixels in the image data is executed.

Claims

1. An output apparatus comprising:

an adjuster that executes a brightness adjustment processing on image data using subject position information, the subject position information indicating a position of a subject in the image data; and

an output section that outputs image data according to the image data having undergone the brightness adjustment processing, wherein

the subject position information has been set automatically, and

the adjuster executes on the image data a processing to increase a brightness value of at least one pixel corresponding to the position of the subject in the image data.

2. The output apparatus according to claim 1, wherein

the adjuster executes on the image data a processing to increase a brightness value of at least one pixel corresponding to the position of the subject in the image data using the image data, the subject position information and subject size information, the subject size information indicating a subject size in the image data, the subject size information having been set automatically.

3. The output apparatus according to claim 1, including:

a judging section that executes a decision as to whether or not to execute the brightness adjustment processing on the image data, wherein

the judging section executes the decision using a weighted average brightness value of the image data calculated with a weight distribution, the weight distribution having different magnitudes at the position of the subject and other positions in the image data.

4. An output method comprising:

executing a brightness adjustment processing on image data using subject position information, the subject position information indicating a position in the image data; and

outputting image data according to the image data having undergone the brightness adjustment processing, wherein

the subject position information has been set automatically, and

the executing of the brightness adjustment processing includes executing on the image data a processing to increase a brightness value of at least one pixel corresponding to the position of the subject in the image data.

5. A computer program product, comprising a computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method comprising:

executing a brightness adjustment processing on image data using subject position information, the subject position information indicating a position of a subject in the image data; and

outputting image data according to the image data having undergone the brightness adjustment processing, wherein

the subject position information has been set automatically, and

the executing of the brightness adjustment processing includes executing on the image data a processing to increase a brightness value of at least one pixel corresponding to the position of the subject in the image data.

6. A printer comprising:

an adjuster that executes a brightness adjustment processing on image data using subject position information, the subject position information indicating a position of a subject in the image data; and

a print section that prints an image according to the image data having undergone the brightness adjustment processing, wherein

the subject position information has been set automatically, and

the adjuster executes on the image data a processing to increase a brightness value of at least one pixel corresponding to the position of the subject in the image data.
