摘要： An original reading apparatus reads out an original which is laid with its surface to be read being directed upward, to thereby convert the read information into an image information. The original reading apparatus has a digitizer function so that a partial reading region of the original is assigned and read out after operator's confirmation by direct observation from an upper side of the surface to be read of the original. A transparent plate on which is depicted reference coordinates for showing a readable region of the apparatus is provided in the vicinity of the original, and a position of the original is finely adjusted on the basis of the reference coordinates. A reading sensor and a carriage mechanism of the original reading apparatus are received in a rotatable upper cover of the apparatus. In case of a large size original, the information thereof is read without any fold or cut of the original.

摘要： While the excitation voltage of an ink jet nozzle is swept on the logarithmic scale, the generation state of ink droplets at a phase .theta..sub.k is examined. An excitation voltage value Vn generating an ink droplet of small diameter at the phase .theta..sub.k, an excitation voltage value Vn generating an ink droplet of large diameter at the phase .theta..sub.k, which is lower than vn, and an excitation voltage value Vn+1 generating an ink droplet of large diameter at the phase .theta..sub.k, which is higher than vn are stored. Difference values expressed asWn=vn-Vnwn=Vn-1-vnare derived on the logarithmic scale. Then the nozzle excitation voltage is set at such a value as to generate ink droplets and minimize the value of .vertline.Wn-wn.vertline..

摘要： A digital camera includes a zoom function for supporting a user when performing a frame assist, and includes an operation switch for instructing startup and completion of the zoom function on an operation unit. A system control unit stores a zoom position in a memory and varies the zoom position in a wide angle position according to a preset zoom-out drive amount when an instruction to startup the zoom function is given by the operation switch. Then, when the instruction to end the zoom function is given by the operation switch, the system control unit executes a zoom-in operation by returning to the zoom position that is stored in the memory.

摘要： In a halftoning unit of a laser printer and the like, a high speed, high density and high gradations halftoning is realized by multi-value implementation by clustered dot concentrated dither halftoning (known as a sub-matrix method) and PWM distributing gradation among the plurality of halftone dots with a small memory and circuit. For this purpose, the value of the difference between an input gradation value ni and a threshold value nc, &Dgr;n=ni−nc, is shortened within a range of 0 to &Dgr;h and the lower s bit of &Dgr;h is removed by a round-down or round-up process. Meanwhile, a threshold array is generated from an extended threshold pattern obtained by combining threshold patterns of 2s whose threshold interval is &Dgr;h, i.e. &Dgr;Ah×K, &Dgr;h×K+1, . . . , &Dgr;×K+2(s−1). Thereby, a halftone dot dither process in which the PWM gradation increases distributively among the 2s dots may be realized with a small scale memory and circuit.
