摘要： The present invention relates to an image processing device and method, a program, and a recording medium whereby the evaluation regarding the reliability of a motion vector can be performed even in the case of an average brightness level between frames changing greatly. On a frame t+1, a block B1 at the position shifted from a pixel p1 to which a pixel p0 on a frame t corresponds by the vector quantity of a correct motion vector v1, and a block B2 at the position shifted from the pixel p1 to which the pixel p0 corresponds by the vector quantity of an incorrect motion vector v2 are shown. Here, the movement of a light source or the like is performed upon the block B1 alone, and even if the brightness level of the block B1 decreases as a whole, determination is made that the evaluation value of the block B1 is high in reliability as compared with the evaluation value of the block B2 by employing the sum of squared brightness values from which the average brightness value within a computation block is subtracted for each frame as an offset. The present invention can be applied to a signal processing device for performing frame frequency conversion processing from a 24P signal to a 60P signal.

摘要： The present invention relates to an image processing device and method, a program, and a recording medium whereby the detection precision of a motion vector by the gradient method can be further improved. A counter value computing unit 451 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 441, a no-horizontal-gradient counter 442, and a no-vertical-gradient counter 443, 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 452 sets in accordance with the computation results. The flag setting unit 452 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. The present invention can be applied to a signal processing device for performing frame frequency conversion processing from a 24P signal to a 60P signal.

摘要： 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.

摘要： 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.
