The present disclosure provides a precise performance three-dimensional ultrasound scanner that is lightweight for an easy hold by suggesting a novel constitution of a swing mechanism wherein an arrangement of the drive motor perpendicular to the swing axis requires a smaller capacity motor and eliminating a backlash. The swing mechanism includes: an arm holder connected to a rotational axis of the motor; an arm connected to the arm holder so that the arm swings within a certain angular range; a link, attached to the arm, for moving in unison with the arm; a shaft, connected to the link, for transmitting a rotary power of the arm to the transducer unit. The swing mechanism can be operated using the smaller capacity motor and eliminates the need for a pulley, gear or belt eliminating backlashes to promote implementation of lightweight precision three-dimensional ultrasound scanners.

Disclosed is an apparatus for generating a vehicle speed signal that can minimize the number of arithmetic operations of an electronic control device. The apparatus includes a PG-B (Pulse Generator B) sensor that is mounted to an output shaft of an automatic transmission, and outputs pulses according to the rotation of the transmission output shaft, a counter that counts pulses from the PG-B sensor and of the predetermined number of pulses are counted, outputs a pulse counter (PC), a vehicle speed signal generation unit that generates a vehicle speed signal in synchronization with the pulse counter (PC) from the counter, an error correction unit that corrects an error in the vehicle speed signal having decimal places from the vehicle speed signal generation unit and defines the vehicle speed signal by an integer ratio, and a speedometer that visualizes and displays the error-corrected vehicle speed signal as a current vehicle speed.
摘要:
A color conversion method, medium, and apparatus, converting a color temperature of an image to a user-set color temperature, on a pixel-by-pixel basis, based on the brightness of each pixel of the image. The color temperature conversion method may include determining a first information associated with a conversion range, determining whether the color temperature of the input pixel needs to be converted by determining, based on the first information, whether the input pixel is within the conversion range, calculating color coordinates of a target point if the input pixel is within the conversion range, and converting the color temperature of the input pixel by moving, in the same direction as the reference poin,t to the target point an amount proportional to the reference point displacement so that the input pixel can be automatically moved along with the reference point of the conversion range.

摘要:
A color temperature conversion method, medium, and apparatus converting an image from one of a plurality of basic color temperatures provided by an image display device to another color temperature other than the plurality of basic color temperatures. Also, the conversion method and apparatus enable pixels of the image with different brightnesses to have different color temperatures according to a user' preference. The color temperature conversion method includes: calculating variables for determining a conversion range; determining whether based on the calculated variables the input pixel is to be color-temperature-converted by determining whether the input pixel is within the conversion range; and converting the color temperature of the input pixel by moving in the same direction as the reference point to the target point in amount proportional to the reference point displacement so that the input pixel can be automatically moved along with the reference point of the conversion range.
