Image storage device and method
First Claim
1. An image storage device comprising:
- a first storage unit which stores first image data;
a second storage unit which stores second image data to be determined whether the second image data includes detection target data which is the same as or similar to data included in the first image data;
a plurality of parallel comparison units which perform a process of comparing at least one of pixel values and pixel value total results between a frame image of the first image data and a frame image of the second image data in parallel, and determining, based on a comparison result between the frame image of the first image data and the frame image of the second image data, whether the detection target data is included in the second image data; and
a third storage unit which stores, when it is determined that the detection target data is included in the second image data, the detection target data or data obtained by encoding the detection target data.

Abstract
An image storage device according to an example of the invention comprising a first storage unit which stores first image, a second storage unit which stores second image to be determined whether the second image includes detection target data which is the similar to data included in the first image, parallel comparison units which perform a process of comparing pixel values between a frame of the first image and a frame of the second image, and determining, based on a comparison result between the frame of the first image and the frame of the second image, whether the detection target data is included in the second image in parallel, and a third storage unit which stores, when it is determined that the detection target data is included in the second image, the detection target data.

14. An image storage method comprising:
-
storing a first image data in a first storage unit and storing in a second storage unit second image data to be determined whether the second image data includes detection target data which is the same as or similar to data included in the first image data; performing in parallel, by a plurality of parallel comparison units, a process of comparing at least one of pixel values and pixel value total results between a frame image of the first image data and a frame image of the second image data, and determining, based on a comparison result between the frame image of the first image data and the frame image of the second image data, whether the detection target data is included in the second image data; and storing, when it is determined that the detection target data is included in the second image data, the detection target data or data obtained by encoding the detection target data, in a third storage unit. - View Dependent Claims (15, 16, 17, 18, 19, 20)
