IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM

摘要

An image processing device includes: an acquisition section configured to acquire image data of a captured image; a dividing section configured to divide the acquired image data into divisional regions; a characteristic-amount calculation section configured to calculate a characteristic amount of the image data in each of the divisional regions; a characteristic-amount storage section configured to update the calculated characteristic amount and store the updated characteristic amount sequentially; and a change determination section configured to perform first and second processings, the first processing being provided to calculate a change amount or an agreement amount between the characteristic amounts, the second processing being provided to calculate a difference value between the characteristic amounts, and the change determination section being configured to determine, based on processing contents of the first and second processings, whether or not the update region is a changed region.

1. An image processing device comprising:
an acquisition section configured to acquire image data of a captured image; a dividing section configured to divide the acquired image data into a plurality of divisional regions; a characteristic-amount calculation section configured to calculate a characteristic amount of the image data in each of the divisional regions; a characteristic-amount storage section configured to update the calculated characteristic amount sequentially, and to store the updated characteristic amount sequentially; and a change determination section configured to perform first processing and second processing, the first processing being provided to calculate a change amount or an agreement amount between the characteristic amount calculated in an update region that is the divisional region in which the characteristic amount is calculated, and the characteristic amount calculated in the divisional region different from the update region in a time direction and/or a two-dimensional coordinate direction, the second processing being provided to calculate a difference value between the characteristic amount calculated currently in the update region, and the characteristic amount calculated earlier in the update region, and the change determination section being configured to determine, based on processing content of the first processing and processing content of the second processing, whether or not the update region is a changed region where a change from image data acquired earlier in the update region is large.
