Abstract:
1. Image processing apparatus, comprising: an image input unit configured to respectively input a plurality of images of a user's face area while the user is gazing at each of a plurality of targets being differently located in a predetermined view space; a pattern generation unit configured to respectively generate a dictionary pattern using the plurality of images for each of the plurality of targets; a dictionary unit configured to store a plurality of dictionary patterns each corresponding to each of the plurality of targets; wherein said input unit inputs an image of the user's face area to specify the user's gaze or face direction, wherein said pattern generation unit generates an input pattern from the image, a pattern comparison unit configured to respectively calculate a similarity degree between the input pattern and each of the plurality of dictionary patterns by comparing the input pattern with each of the plurality of dictionary patterns; and a gaze detection unit configured to detect the user's gaze or face direction based on the similarity degree.
