摘要： 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. The above can be applied to a signal processing device for performing frame frequency conversion processing from a 24P signal to a 60P signal.

摘要： PROBLEM TO BE SOLVED: To improve detection precision of a moving vector more as to an image processor which converts the frame frequency of an image. SOLUTION: An intercept arithmetic part 623 calculates an intercept of a straight line consisting of points corresponding to groups of components of movement in a 1st direction and components of movement in a 2nd direction as to pixels meeting the condition that luminance is constant in a coordinate system including the movement in the 1st direction as a 1st axis and the movement in the 2nd direction as a 2nd axis based upon the gradient of a specified pixel of a block of interest on a frame in the 1st direction and the gradient of the specified pixel in the 2nd direction, and a gradient of the specified pixel in a time direction. A intercept position decision part 624 decides whether the specified pixel is sued for specified arithmetic processing for detecting the moving vector of a pixel of interest in the block of interest. This method is applicable to a signal processor which performs frame frequency conversion from a 24P signal into a 60P signal. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To select an initial vector for improving the detecting precision of moving vectors by a gradient method. SOLUTION: The "S" of a block Bt under consideration indicates that a shift initial vector SV is used as an initial candidate vector. The "C" of a block on the left of the block Bt under consideration indicates that the current vector CV of the block of the current frame t is used as the initial candidate vector. When it is judged that the past vector PV of the block of the past frame t-1 is similar to the shift initial vector SV of the block, the "P/S" of a block on the lower right of the block Bt under consideration indicates that the past vector PV is used as the initial candidate vector, and when the past vector PV is different from the shift initial vector SV, it indicates that the shift initial vector SV is used as the initial candidate vector. This method apply to the signal processor which performs frame frequency conversion processing from a 24P signal to 60P signal. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To improve precision of allocation of a moving vector to a generated frame more. SOLUTION: A moving vector sv a is generated by shifting a moving vector va detected at a pixel (x a , y a ) on a frame (t) onto a nearby pixel G4 as an allocation candidate vector of the pixel G4. Here, intersections of the moving vector sv a shifted onto the pixel G4 and frames (t) and (t+1) are considered to be points P and Q respectively. When the points P and Q belong to, for example, different objects, the difference between a luminance value F t (P) at the point P and a luminance value F t+1 (Q) at the point Q becomes large, so a vector allocation part 54 finds the luminance difference absolute value dp of a pixel G as evaluation of the moving vector sv a by using the points P and Q and judges whether the luminance difference absolute value is larger than a specified value or not. This method is applicable to a signal processor which performs frame frequency conversion processing from a 24P signal into a 60P signal. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To selectively enable duplication of only the designated hierarchical discrimination level of a hierarchized broadcast program. SOLUTION: In coding portions 14, 24, and 30, a broadcast information including video image information and speech information is encoded. Two or more broadcastings in the broadcast information are layered in two or more levels. Additional information generating means 16 and 26 forms an identification code which specifies the service information, and additional information, including the discrimination level for discriminating which level of the two or more levels is with respect to each of two or more broadcastings. In a multiplexing part, an encoded information encoded by a coding means and an additional information formed by the additional information generating means are multiplexed. A transmitting portion 34 transmits a multiplexed information. By utilizing the identification code, a specific program can be preserved automatically. Further, by specifying a layer identifying level, selective monitoring of only the broadcasting content which has hierarchization identifying level from a recorded program can be made.
