Abstract
An image processing apparatus that superimposes additional information on image data, the apparatus sets, in the image data, a main region in which the superimposing intensity for superimposing the additional information is constant, and a superimposing intensity change region in which the superimposing intensity for superimposing the additional information is not constant, sets, the superimposing intensity according to the target pixel in the superimposing intensity change region, and superimposes the additional information on image data using the set superimposing intensity.
Claims9
An image processing apparatus that superimposes additional information on image data, the apparatus comprising:
- a region setting unit configured to set, in the image data, a main region in which the superimposing intensity for superimposing the additional information is constant, and a superimposing intensity change region in which the superimposing intensity for superimposing the additional information is not constant,
- a superimposing intensity setting unit configured to set the superimposing intensity according to the position of a target pixel, and
- a superimposing unit configured to superimpose the additional information on image data of the target pixel using the superimposing intensity set by the superimposing intensity setting unit, the superimposing intensity being set constant when the position of the target pixel is in the main region, and the superimposing intensity being changed according to the position of the target pixel when the position of the target pixel is in the superimposing intensity change region.
A method for image processing executed in an image processing apparatus that superimposes additional information on image data, the method comprising the steps of:
- setting, in the image data, a main region in which the superimposing intensity for superimposing the additional information is constant, and a superimposing intensity change region in which the superimposing intensity for superimposing the additional information is not constant,
- setting, in the superimposing intensity change region, the superimposing intensity according to the position of a target pixel, and
- superimposing the additional information on image data of the target pixel using the superimposing intensity set in the step of setting the superimposing intensity, the superimposing intensity being set constant when the position of the target pixel is in the main region, and the superimposing intensity being changed according to the position of the target pixel when the position of the target pixel is in the superimposing intensity change region.
A computer-readable medium storing an image processing program for superimposing additional information on image data, the program causing a computer to function to:
- set, in the image data, a main region in which the superimposing intensity for superimposing the additional information is not constant, and a superimposing intensity change region in which the superimposing intensity for superimposing the additional information is not constant,
- set, in the superimposing intensity change region, the superimposing intensity according to the position of a target pixel, and
- superimpose the additional information on image data of the target pixel using the superimposing intensity, the superimposing intensity being set constant when the position of the target pixel is in the main region, and the superimposing intensity being changed according to the position of the target pixel when the position of the target pixel is in the superimposing intensity change region.
