Information processing device, information processing method, and recording medium
First Claim
1. An information processing device comprising:
- an image inputter configured to input image data in which a user has been captured;
an extractor configured to extract a region corresponding to a hand of the user included in the image data input by the image inputter;
a determinator configured to determine whether or not the region corresponding to the hand of the user extracted by the extractor is in a stationary state;
a recognizer configured to, if the region corresponding to the hand of the user is determined by the determinator as being in a stationary state, recognize the shape of the region corresponding to the hand of the user extracted by the extractor; and
an inputter configured to input data associated with the shape recognized by the recognizer,wherein the extractor is further configured to set a rectangle that circumscribes a movement region obtained from difference data between frames in the image data input by the image inputter, specify a region corresponding to a wrist of the user, on the basis of a width of the hand included in the movement region obtained by scanning the inside of the rectangle, and extract the region corresponding to the hand of the user, on the basis of the specified region corresponding to the wrist of the user.

Abstract
An image inputter inputs image data in which a user has been captured. An extractor extracts a region corresponding to a hand of the user included in the image data input by the image inputter. A determinator determines whether or not the region corresponding to the hand of the user extracted by the extractor is in a stationary state. If it is determined by the determinator that the region corresponding to the hand of the user is in a stationary state, a recognizer recognizes the shape of the region corresponding to the hand of the user extracted by the extractor. Otherwise, if it is determined by the determinator that the region corresponding to the hand of the user is not in a stationary state, the recognizer recognizes the movement of the region corresponding to the hand of the user extracted by the extractor. An inputter inputs data associated with the shape or the movement recognized by the recognizer.

8. An information processing method including:
-
an image input step for inputting image data in which a subject has been captured; an extraction step for extracting a region corresponding to a hand of the user included in the image data input in the image input step; a determination step for determining whether or not the region corresponding to the hand of the user extracted in the extraction step is in a stationary state; a recognizing step for, if the region corresponding to the hand of the user is determined in the determination step as being in a stationary state, recognizing the shape of the region corresponding to the hand of the user extracted in the extraction step; and an input step for inputting data associated with the shape recognized in the recognizing step, wherein the extraction step further includes setting a rectangle that circumscribes a movement region obtained from difference data between frames in the image data input in the image input step, specifying a region corresponding to a wrist of the user, on the basis a width of the hand included in the movement region obtained by scanning the inside of the rectangle, and extracting the region corresponding to the hand of the user, on the basis of the specified region corresponding to the wrist of the user.

9. A non-transitory recording medium on which a program is recorded, the program causing a computer to function as:
-
an image inputter configured to input image data in which a subject has been captured; an extractor configured to extract a region corresponding to a hand of the user included in the image data input by the image inputter; a determinator configured to determine whether or not the region corresponding to the hand of the user extracted by the extractor is in a stationary state; a recognizer configured to, if the region corresponding to the hand of the user is determined by the determinator as being in a stationary state, recognize the shape of the region corresponding to the hand of the user extracted by the extractor; and an inputter configured to input data associated with the shape recognized by the recognizer, wherein the extractor is further configured to set a rectangle that circumscribes a movement region obtained from difference data between frames in the image data input by the image inputter, specify a region corresponding to a wrist of the user, on the basis of a width of the hand included in the movement region obtained by scanning the inside of the rectangle, and extract the region corresponding to the hand of the user, on the basis of the specified region corresponding to the wrist of the user.
