Abstract: A recycling aid system for aiding a recycling process of an electronic apparatus is disclosed. The recycling aid system includes: the electronic apparatus; a radio communication apparatus placed in a location on a route through which the electronic apparatus moves; and a management server apparatus connected to the electronic apparatus via the radio communication apparatus. The electronic apparatus includes: a unit configured to obtain physical measurement data of environment of the electronic apparatus, and to store the physical measurement data in a storage unit; a unit configured to obtain traceability data, and to store the traceability data in the storage unit; a unit configured to transmit the environment history data and the traceability data to the management server apparatus; and a unit configured to receive data including the environment history data and the traceability data from the management server apparatus, and to visually output the received data.

Abstract: A method for forming images composed of a matrix of dots in a printer, such as a laser printer or an LED printer, and a bit map display unit such as a CRT display, and more particularly a method for smoothing images by smoothing stairsteps included in the images to obtain a high resolution image. The method includes dividing a pixel into a plurality of subpixels along a vertical scanning line or a horizontal scanning line, and reversing a signal for a subpixel following a reversion signal to smooth the image as desired. The reversion signal may be provided by subjecting a specific pixel to a boolean operation, conjunction or disjunction, with the adjacent pixels next to the specific pixel.
