Abstract: PURPOSE:To provide an image deforming method and device therefor which can smoothly display the images with a small memory capacity and even when the original image data are displayed after the complicated deformation that requires its processing time. CONSTITUTION:When an animation display command is produced by the push of an animation switch 21, the original image data 51 are previously deformed end (n) sheets of deformed image data 41a-41n are generated. These data 41a-41n are stored in a deformed image data memory 4 and then read out in sequence for the purpose of animations, thereby, the animation of the data 31 is shown on a display 7. By this, the memory capacity can be extremely reduced for storage of data necessary for display of animations.

Abstract: PURPOSE:To deform the image date without impairing the color tone of the original image date despite the deformation of a part of a halftone color end without deforming only a part of the image data of a bit array form despite its deformation. CONSTITUTION:A color is designated for the pellet numbers of double color dots forming an elliptical graphic B shown in (a), and the lines to be displayed as the deformed image data are successively selected out of the original image data. Thus, the image data reduced in the vertical direction end shown in (c) are obtained. At the same time, it is decided whether the dots of the designated color are included in the lines every time a line is selected from the original image data. If the dots of the designated color are included, the corresponding dots of the rear image data shown in (b) ere reed out and displayed in place of the dots of the designated color.

Abstract: PURPOSE:To provide an image deforming method/device, by which the image of a bit array system can freely and smoothly be deformed with less memory capacity. CONSTITUTION:When four small rectangles included in the internal designated range of a deformed object are moved to arbitrarily positions (moved so that the positions of apexes are changed, for example), the apex of the other small rectangle is moved so that the whole deformed object is smoothly deformed, and the apex of the other moved small rectangle is calculated based on the moved apex of the small rectangle in the designated range becoming a reference. At that time, data for moving the rectangle are a grid point (p1, q1) at the upper left of the whole four small rectangles, a grid point (p2, q2) at the lower right and data for deforming the small rectangles within the designated range, namely, the coordinates of the four apexes after deformation in the designated range. The forms of the respective small rectangles are decided in accordance with the calculated apexes, and an original image is deformed so that it corresponds to data of the deformed small rectangles so as to generate the whole image.

Abstract: PURPOSE:To delay and output digital input data of a musical sound, a speech, etc., inputted at optional timing in real time at specific intervals or at constant timing matched with the beats, etc., of an accompaniment melody. CONSTITUTION:A CPU 102 generates sound source data according to key operation on a keyboard 101 and outputs the data together with added envelope data. A sound source 103 generates musical sound data according to the sound source data and waveform data read out of a waveform memory 104 and outputs the data. A DSP 105 adds effect to the musical sound data or speech data inputted through an A/D converter 114 and writes the resulting data in an input data memory 115. At this time, the address of the waveform rising of the input data is stored as a readout start address and the address of the waveform falling is stored as a readout end address. The input data from the stored readout start address to the readout end address are read out of the input data memory 115 each time a certain interval time is elapsed or at the timing of each beat of the automatic accompaniment melody sound and outputted to a D/A converter 107.

Abstract: PURPOSE:To obtain a smooth change from a musical sound with a certain tone to a musical sound with a different tone in accordance with touching operation and to effectively detune musical sounds. CONSTITUTION:When a velocity curve is small, a weak musical sound waveform is generated from a sound source line alpha out of two sound source lines alpha, betaat a level based upon an alpha touch curve to be a velocity curve, and in an area exceeding a velocity split point, a strong musical sound waveform is generated at a level based upon the alpha touch curve. From the other line beta also, a weak musical sound waveform is generated at a level based upon a beta touch curve in a velocity area smaller than a set velocity split paint, and in an area exceeding the split point, a strong musical sound waveform is generated at a level based upon the beta touch curve. Both the musical sound waveforms are read out based upon respectively different frequency bands and mixed and generated in accordance with respective touch curves.
