Patent number: 8385602Abstract: An image processing device and method, a program, and a recording medium whereby the detection precision of a motion vector by the gradient method is further improved. A counter value computing unit acquires the number of valid pixels, the number of pixels having no gradient in the horizontal direction, and the number of pixels having no gradient in the vertical direction from a valid pixel number counter, a no-horizontal-gradient counter, and a no-vertical-gradient counter, computes the ratio between valid pixels within a computation block and one-sided gradient pixels among the valid pixels, and controls the value of a flag which a flag setting unit sets in accordance with the computation results. The flag setting unit sets the value of a gradient flag, and outputs the gradient flag to the subsequent stage. At the subsequent stage, gradient method computation and vector evaluation processing are executed based on the gradient flag.Type: GrantFiled: September 7, 2006Date of Patent: February 26, 2013Assignee: Sony CorporationInventors: Akihiko Kaino, Takashi Horishi, Yukihiro Nakamura, Kunio Kawaguchi, Yasuaki Takahashi, Norifumi Yoshiwara, Takafumi Morifuji, Yuta Choki

Patent number: 7848427Abstract: For each pixel in an operation block, an effective pixel determining unit sets a predetermined pixel difference (threshold value) on a time-base pixel difference. When the time-base pixel difference is less than the set predetermined pixel difference, it is determined that the pixel contributes to (or are effective in) motion vector detection, and uses the pixel in the gradient method in the case of performing motion vector detection. When the time-base pixel difference is not less than the set predetermined pixel difference, it is determined that the pixel is regarded as having a possibility to generate irregularity in movement, and the pixel is excluded from the gradient operation in the case of performing motion vector detection. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion from a 24 P signal to a 60 P signal.Type: GrantFiled: April 8, 2005Date of Patent: December 7, 2010Assignee: Sony CorporationInventors: Takashi Horishi, Norifumi Yoshiwara, Yukihiro Nakamura, Akihiko Kaino, Kunio Kawaguchi, Yasuaki Takahashi, Yuta Choki, Tetsujiro Kondo

Patent number: 7738556Abstract: A past frame at a past time has a motion vector in a block, and a reference frame at a reference time has a different block which is a motion-compensated block identical in position to a terminal point of a motion vector in the block. When a gradient method is used to detect a motion vector in the different block in the reference frame, a motion vector which is identical in magnitude and orientation to a motion vector and whose initial point is the different block in the reference frame is used as a candidate vector for initial vectors. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion from a 24P signal to a 60P signal.Type: GrantFiled: April 8, 2005Date of Patent: June 15, 2010Assignee: Sony CorporationInventors: Yukihiro Nakamura, Yasuaki Takahashi, Takashi Horishi, Kunio Kawaguchi, Norifumi Yoshiwara, Akihiko Kaino, Yuta Choki
