    摘要: To solve problems associated with undesirable duplication of see-through back image in a double-sided input document, a method of and a system for substantially eliminating the undesirable see-through back images initially scanns a front side image and a back side image from the double-sided document and store the scanned images. The front side image has portions, and some of the portions include an original front image as well as a see-through back image from the back side image. An edge amount for each of the portions is determined in the front side image. The see-through back images are separated from the original front images based upon the edge amount. To further improve the correct removal of the undesired see-through back image, the above processed portions having a certain edge are smoothed. Character portions and dot pattern portions are further separated from background portions in the smoothed data. Finally, the intensity level of the character portions, the dot pattern portions and the background portions are adjusted by a corresponding predetermined conversion function so as to substantially eliminate the see-through back image.

    摘要: A circuit for providing a constant coloring current to a plurality of segment electrodes of an electrochromic display comprises a plurality of switching elements, say, transistors respectively connected to the segment electrodes for enabling the application of the constant coloring current to the segment electrodes, and an element for changing switching timings of the switching elements. A desirable amount of charge derived from the constant coloring current is applied to the segment electrodes regardless of the presence of the variations in electrical properties of the respective switching elements. In another form of the present invention, the changing element comprises a generator for generating a constant voltage, and a modifier for modifying a value of the constant voltage. In a further form of the present invention, the sizes of the respective switching elements, say, MOS transistors can be changed so that the factor W/L (W: the width of a channel of one of the MOS transistors, and L: the length of the channel) is selected so as to be proportional to the dimensions of the corresponding segment electrodes.
