    • An image encoder and an image decoder which perform the image displacement other than parallel displacement on a relatively small scale and with which the processing time can be reduced and estimation with a high precision is enabled. The constitution for compression-coding the input image comprises a movement compensating means which detects the frame-to-frame movement of the blocks into which the input image is divided. The constitution further comprises a movement detection unit which includes a deformed block matching section which deforms only integer pixels, i.e. real sampling points present in a partial region corresponding to a reference image for movement detection into predetermined formats, cuts the deformed pixels out, and compares the cut-out deformed pixels with the integer pixels of the blocks of the input image and which outputs a moving vector which gives a minimum error extracted by the coordinate designation and a movement compensation unit which includes a corresponding point determination section which includes the deformed block matching section, correlates the blocks of the reference image in accordance with movement parameters obtained from comparison output, designates the coordinates, deforms and determines the block, and which outputs a predicted partial image. Further, an image decoder is so constructed as to correspond to the construction of the encoder. Moreover, the image decoder calculates the coordinates with a plurality of movement vectors by using also the coordinate values of the half-pixels of the reference image in a movement compensating means and subjects the obtained pixel values to a deformation processing by using a deformation pattern in accordance with a deformed pattern.

    • A pulse power source apparatus which quickly discharges the charged voltage of a capacitor (23) by closing a switch (24). First and second serial circuits (51 and 52) are connected in series between the output terminals of a DC voltage source (2). The first serial circuit (51) is composed of a first reactor (14) and a first forward diode (15), and the second serial circuit (52) is composed of a second forward diode (16) and the switch (24). A third serial circuit (53) composed of the capacitor (23), a second reactor (25), and a discharge tube (9), and the discharge tube is connected in parallel with the second serial circuit (52). When the switch (24) is closed, the discharge tube (9) emits light, but the discharged current from the capacitor (23) becomes an oscillating current and a voltage of the opposite polarity to that of the voltage generated at the initial charging time is generated in the capacitor (23). Since the oscillating voltage is superposed upon the power supply voltage and utilized at the next charging cycle time, an extremely efficient pulse power source apparatus can be obtained.
