Publication number: 20130230209Abstract: The present invention improves the recognition rate of an augmented reality marker and the processing speed thereof, simultaneously. In the present invention, a CPU binarizes actual image captured in an image sensor in accordance with an adaptive thresholding, and detects an augmented reality marker from within the binarized image. Then, the CPU determines a binarization threshold based on the augmented reality marker, and after binarizing the actual image captured in the image sensor in accordance with a fixed threshold binarization method using the binarization threshold, recognizes the augmented reality marker based on the binarized image.Type: ApplicationFiled: February 11, 2013Publication date: September 5, 2013Applicant: CASIO COMPUTER CO., LTD.Inventors: Shogo HASHIMOTO, Akira HAMADA, Yoshihiro TESHIMA

Patent number: 8526740Abstract: The interval designation section 222 sequentially alters and designates a movement interval D and a non-movement interval D? in an entire interval. Each time a movement interval D is designated, the value determination section 223 determines the average value of the image variation amount array E in the movement interval D as a function value a of the unit rectangular function r[x] and the average value of the image variation amount array E in the non-movement intervals D? as a function value b of the unit rectangular function r[x]. Each time a movement interval D is designated, a degree of divergence J between the function values a, b and the image variation amount array E is calculated by the divergence calculation section 224. Then, only the frame images contained in the movement interval D designated when the degree of divergence J is at a minimum are extracted.Type: GrantFiled: July 31, 2009Date of Patent: September 3, 2013Assignee: Casio Computer Co., Ltd.Inventor: Akira Hamada

Patent number: 8488899Abstract: A filter coefficient calculating unit 81 sets as a filter window a range, which contains plural coordinates including an attention coordinate “p” in an initial alpha map, and uses a pixel value Ip at a coordinate of an original image corresponding to a coordinate “p” in the filter window and a pixel value Iq at a coordinate of the original image corresponding to a coordinate “q” in the filter window to calculate a filter coefficient Kq at the coordinate “q” on a coordinate to coordinate basis in the filter window. That is, a filter coefficient set is created, which consists of filter coefficients calculated on a coordinate to coordinate basis in the filter window. A weighted-average filtering unit 83 uses the filter coefficient set to apply a weighted-average filtering operation on each pixel value in the filter window.Type: GrantFiled: July 1, 2011Date of Patent: July 16, 2013Assignee: Casio Computer Co., Ltd.Inventor: Akira Hamada

Publication number: 20120114035Abstract: The minimum Sum of Absolute Differences obtained by a motion vector search roughly judges the magnitude of quantization error by whether or not exceeding a predetermined threshold value. When the quantization error is lower, whether or not visually noticeable noise exists in some of the pixels of the current macroblock is judged based on the amount of flatness and noise detected in each of the 4×4 pixel blocks of the current macroblock partitioned into 16 sub-macroblocks. If there is visually noticeable noise, intra-frame coding is selected. When the quantization error is higher, whether or not visually noticeable noise exists in the current macroblock is judged while considering the magnitude of the motion vector. If there is visually noticeable noise, intra-frame coding is selected.Type: ApplicationFiled: January 17, 2012Publication date: May 10, 2012Applicant: Casio Computer Co., Ltd.Inventors: Kouichi Nakagomi, Akira Hamada, Shinichi Matsui
