Abstract: The image forming device according to the present invention performs resolution conversion processing or scaling processing of a binary image and outputs a processed image. The present image forming device is provided with an edge detecting section, which, during resolution conversion or scaling of the binary image, detects edges of the image and detects lengths and shapes of the edges, and with an interpolated/skipped line producing section, which performs resolution conversion processing or scaling processing based on the lengths and shapes of edges detected by the edge detecting section.

Abstract: A presenting time for an animation is determined as follows for each of a plurality of frames of the animation in passage of time at a prescribed speed which can be changed as desired. First, for each of the plurality of frames, a signal indicating a timing corresponding to a boundary between adjacent frames is applied. Then, in accordance with the applied timing indication signal, a presenting time is determined and recorded onto a medium corresponding to each frame. A producer operates a keyboard, mouse or the like to input the timing indication signal at an arbitrary timing. In addition, the timing indication signal is input at a timing determined in accordance with the regenerated guide track information while guide track information (information to be referenced for identifying the aforementioned boundary) is regenerated at a regeneration rate in accordance with a prescribed speed.

Abstract: An exposure apparatus for image formation uses power control means provided to a laser driver for controlling exposure energy and accordingly forming an image. Specifically, exposure energy is varied depending on an isolated-dot pattern and an isolated-line pattern by changing the pulse height (drive power) of a drive pulse for each dot. Both of the isolated-line and isolated-dot patterns of a high resolution can thus be reproduced with a high image quality without increase of cost due to requirements for accuracy in processing and positioning of a lens and without decrease of life of a photoreceptor due to a decreased thickness of its photosensitive layer.
