IMAGE RECOGNITION DEVICE, FOCUS ADJUSTMENT DEVICE, IMAGING APPARATUS, IMAGE RECOGNITION METHOD AND FOCUS ADJUSTMENT METHOD
First Claim
1. An image recognition device comprising:
- an imaging unit configured to acquire first image information and second image information;
a holding unit configured to hold reference information that functions as a reference image;
a detection unit connected to the holding unit and configured to detect a first difference between partial information of at least a part of the first image information and the reference information and to detect a second difference between partial information of at least a part of the second image information and the reference information;
a recognition unit connected to the holding unit and configured to recognize a first area corresponding to the reference image in the first image information; and
a calculation unit connected to the detection unit and configured to calculate a determination value based on a reference area in the second image information corresponding to the first area by weighting the second difference, the recognition unit being configured to recognize a second area corresponding to the reference image in the second image information based on at least one of the second difference and the determination value.

Abstract
An image recognition device includes a detection unit which is configured to detect a first difference between partial information of at least a part of the first image information and the reference information and to detect a second difference between partial information of at least a part of the second image information and the reference information. A recognition unit is configured to recognize a first area corresponding to the reference image in the first image information. A calculation unit is configured to calculate a determination value based on a reference area in the second image information corresponding to the first area by weighting the second difference. The recognition unit is configured to recognize a second area corresponding to the reference image in the second image information based on at least one of the second difference and the determination value.

27. An image recognition device comprising:
-
imaging means for acquiring first image information and second image information; holding means for holding reference information that functions as a reference image; detection means for detecting a first difference between partial information of at least a part of the first image information and the reference information and to detect a second difference between partial information of at least a part of the second image information and the reference information; recognition means for recognizing a first area corresponding to the reference image in the first image information; and calculation means for calculating a determination value based on a reference area in the second image information corresponding to the first area by weighting the second difference, the recognition means being for recognizing a second area corresponding to the reference image in the second image information based on at least one of the second difference and the determination value.
