  • Patent number: 6674798
    Abstract: A processor array includes element processors which are arranged in a matrix in correspondence to respective pixels of a template block, which is a current picture image pixel block. Each element processor stores pixel data of a search window block, which is a corresponding reference picture image pixel block, and obtains an evaluation function value component with respect to the template block pixel data. A summing part sorts the evaluation function components received from the respective element processors of the processor array in accordance with a plurality of predictive modes and sums up the components for the respective sorts, for forming evaluation function values for the respective predictive modes. A comparison part compares the evaluation function values received from the summing part for each predictive mode, to decide a displacement vector providing the best similarity as a motion vector for each predictive mode.

  • Publication number: 20030181009
    Abstract: A silicon oxide film is formed by thermal oxidation on condition that the thickness thereof on the surface of a diffusion layer is about 3 nm. As a result, the silicon oxide film with a thickness of about 12 nm is formed on the surface of a source diffusion layer due to enhanced oxidation. Subsequently, after a silicon nitride film is formed on the entire surface, the silicon nitride film in a peripheral transistor region is removed. Thereafter, the resist film is removed, and thermal oxidation is performed in order to grow the silicon oxide film formed on the surface of the diffusion layer. On this occasion, the silicon oxide film formed on the surface of each of the source diffusion layer and the drain diffusion layer is covered with the silicon nitride film, and hence it does not grow.

  • Patent number: 6611132
    Abstract: A DC-DC converter for decreasing power consumption and quickly increasing an output voltage. The converter includes a voltage generation circuit, a switching control circuit, a current detection circuit, and a step control circuit. An output transistor performs switching to generate the output voltage of the switching control circuit. The current detection circuit is connected to the voltage generation circuit to detect a load current, which is derived from the output voltage, and to generate a detection signal. A stop control circuit maintains the output transistor in an activated state in accordance with the detection signal and stops the operation of the switching control circuit when the load current is less than or equal to the load current.

  • Publication number: 20030137330
    Abstract: A semiconductor device includes a delay amount measuring unit, multiple delay sections and a correction signal generating unit. The delay amount measuring unit for measures an actual delay amount corresponding to a specified delay amount by supplying a clock signal with a known period to multiple 1-ns-delay strings with a preassigned delay amount, and by detecting phase variations of the clock signal by the 1-ns-delay strings. The delay sections includes a delay string capable of freely adjusting a connection number of its delay elements. The correction signal generating unit generates a correction signal for enabling each of the delay sections to correct the connection number of the delay strings such that each delay section has a desired delay amount, in accordance with the actual delay amount corresponding to the specified delay amount and measured by the delay measuring unit.

  • Publication number: 20030078086
    Abstract: A golf game device that generates a natural interest in golf without taking up a large amount of space. A player swings a grip which is shaped like the grip of a golf club. On a first monitor, a virtual club head moving in accordance with the movement of the grip is displayed. An imaginary shaft extends from the grip, and the virtual club head is displayed as if it were attached to the end of the shaft. The player takes aim at his target direction (to which a ball is to be hit) by viewing scenery displayed on a second monitor, and hits a ball displayed in his underfoot view on the first monitor. The front view and underfoot view change according to the position where a virtual player stands in the game space. Accordingly, the player can play with the sense that he is actually playing a golf course.
