Patent Images
1. An image processing apparatus comprising:
- a sensor that comprises a plurality of elements for converting radiation corresponding to a plurality of partial images into respective electrical signals;
an A/D converter that converts the electrical signals to image data; and
correction means for correcting a step between the plurality of partial images in the image data on the basis of a statistical value,wherein said correction means calculates a plurality of step values from a difference between pixel values located along a boundary between the plurality of partial images, and calculates the statistical value from the plurality of calculated step values.

Abstract
An image processing apparatus includes an image processing circuit having a first mode that corrects an offset between a first image and a second image that are adjacent to each other to synthesize the first image and the second image into a new third image, and a second mode that corrects an offset between the third image and a fourth image that are adjacent to each other to synthesize the third image and the fourth image into a new fifth image.

12. An image processing method of forming one image from a plurality of partial images which do not overlap with each other, said method comprising:
-
a first calculation step of calculating a plurality of step values from a difference between pixel values located along a boundary between the plurality of partial images; a second calculation step of calculating a statistical value from the plurality of step values calculated in said first calculation step; and a correction step of correcting a step between the plurality of partial images on the basis of the statistical value. - View Dependent Claims (13)
