  • Publication number: 20090136146
    Abstract: 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.

  • Publication number: 20070263323
    Abstract: Embodiments in accordance with the present invention provide a magnetic head assembly in which a slider can be removed with deformation of a suspension suppressed and the posture angle of a magnetic head can be maintained stably, and a magnetic disk drive mounted with the magnetic head assembly. A head gimbal assembly (HGA) according to an embodiment includes a suspension, a magnetic head slider provided with a magnetic head element section, and gimbal retaining the slider and connected to the suspension. The gimbal includes a spacer formed around a conductive adhesive application area. A nonconductive adhesive application area having a planar dimension not larger than that of the conductive adhesive application area is formed outside the slider. The gimbal and the slider are brought into conduction through a conductive adhesive applied to the conductive adhesive application area and are adhered to each other with a nonconductive adhesive applied to the nonconductive adhesive application area.

  • Patent number: 7210221
    Abstract: A base plate and load beam for an HG assembly are formed in series, stacked, and transferred by a transfer system in the form of the stacked-layer series to undergo the necessary assembly processes such as layer joining, slider attachment, and electrical connections between the terminals thereon. When uncompleted HG assemblies are transferred for each of the manufacturing processes, the uncompleted HG assembly is mounted on the assembly jig such as a tray or a block for transference. For this reason, assembling jigs, the number of which is at least equal to the number of the uncompleted HG assemblies remaining at the respective assembly processes would be needed. Accordingly, the efficiency of work space is reduced, and a rise in manufacturing cost is brought about by the need for the assembling jigs.

  • Publication number: 20060153390
    Abstract: The acoustic signal transmission method is based on generating a synthesized sound electrical signal by electrically synthesizing an audible sound signal and another signal different than the audible sound signal at the sending side, and transmitting the synthesized sound electrical signal, and extracting the another signal different than the audible sound signal from the synthesized sound electrical signal at the receiving side. Here, generation of the synthesized sound electrical signal is made by using a data hiding technique, for example. Accordingly, the acoustic signal represented by the synthesized sound electrical signal can be heard by human ears in the same way as the audible sound signal, and the synthesized another signal cannot be detected by human ears. Here, the synthesized sound electrical signal can be transmitted as a sound wave in air space, as electrical signal through a transmission line or as radio signals such as infrared and electromagnetic waves.

  • Patent number: 7069187
    Abstract: An authentication processing apparatus for performing authentication based on a user's normal operation is provided. The authentication processing apparatus performs the authentication processing on the basis of operation information obtained from normally operating an information processing apparatus. Operation information obtained from operating an input unit by the user, such as a keyboard inputting mode, is obtained to serve as operation information, and the obtained operation information is checked against operation information registered in a database to perform authentication. Authentication is thus made possible without requiring the user to perform the special input processing for the authentication processing. Authentication is performed taking into consideration a plurality of pieces of operation information. With the checking processing in which less dispersed data is weighted, user authentication with high accuracy is made possible.

  • Publication number: 20060126934
    Abstract: Embodiments of the invention provide a method for setting a light source parameter in order to recognize an identification mark on an object surface. In one embodiment, a grayscale image is generated by setting the light volume of the light source to a given value. Plural thresholds each for binarizing the grayscale image in density are set. The inter-class variance values to be produced respectively according to the thresholds are calculated and the largest inter-class variance value is selected as the peak inter-class variance value from the inter-class variance values calculated. The light volume is changed to a plurality of different values. Peak inter-class variance values are obtained respectively for the values and the largest peak inter-class variance value is selected as the maximum inter-class variance value from the peak inter-class variance values obtained.

  • Publication number: 20050259739
    Abstract: 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.

  • Publication number: 20050259738
    Abstract: 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.
