Abstract: A display control apparatus includes: a change detection unit that detects a change of a UI element on a target screen; a determination unit that determines a display update method among a plurality of display update methods for extended UIs based on the change of the UI element detected by the change detection unit; and a display update unit that updates display of the extended UIs by the display update method determined by the determination unit.

Abstract: A microlens array, which maintains high positional accuracy with respect to an optical circuit such as a waveguide and facilitates connection operation, and an optical transmission component including the microlens array. Solution The microlens array is provided with a plurality of microlenses arranged in an array structure and having the same length in the optical axis direction and optical fibers for alignment arranged at both ends of the array structure so that the optical axis is parallel to the optical axis of the microlens and having a length in the optical axis direction the same as the length of the microlens and a guided mode diameter smaller than an aperture of the microlens.

Abstract: The image printing system is capable of properly defining amount of ink without adjusting ink clearance. The image printing system includes an offset printing machine, in which proper amount of ink is supplied to a plate drum via an ink fountain roller on the basis of image data. A memory stores the image data of an original image and an ink amount table, in which rotational speed data of the ink fountain roller correspond to rate of area of picture in the original image. A control unit calculates the rate of area of picture on the basis of the image data, reads the rotational speed of the ink fountain roller from the ink amount table on the basis of the rate of area of the picture, corrects the rotational speed so as to define proper control data for rotating the ink fountain roller, and sends the proper control data to the offset printing machine so as to control the amount of ink to be supplied to the plate drum.
