Abstract
An image processing apparatus includes a comparison unit and a control unit. The comparison unit compares a light-dark pattern of a plurality of pixels of an input image with a previously-stored pattern to determine a semitransparent object. The plurality of pixels include a pixel of interest and peripheral pixels thereof. The control unit changes intensity of edge correction processing to be applied to the pixel of interest in at least three levels based on a result of the comparison by the comparison unit.
Claims7
An image processing apparatus comprising:
- a comparison unit configured to compare a light-dark pattern of a plurality of pixels of an input image with a previously-stored pattern to determine a semitransparent object, wherein the plurality of pixels include a pixel of interest and peripheral pixels thereof;
- and
- a control unit configured to change intensity of edge correction processing to be applied to the pixel of interest in at least three levels based on a result of the comparison by the comparison unit.
A method for an image processing apparatus, the method comprising:
- comparing a light-dark pattern of a plurality of pixels of an input image with a previously-stored pattern to determine a semitransparent object and. obtain a result, wherein the plurality of pixels include a pixel of interest and peripheral pixels thereof;
- and
- changing intensity of edge correction processing to be applied to the pixel of interest in at least three levels based on the result of the comparison.
A non-transitory storage medium storing a program to cause a computer to perform a method for an image processing apparatus, the method comprising:
- comparing a light-dark pattern of a plurality of pixels of an input image with a previously-stored pattern to determine a semitransparent object and obtain a result, wherein the plurality of pixels include a pixel of interest and peripheral pixels thereof;
- and
- changing intensity of edge correction processing to be applied to the pixel of interest in at least three levels based on the result of the comparison.
