To enable a necessary image data to be easily found out based on image sizes of a plurality of index images displayed in a list format and to enable contents of original images displayed as index images to be easily understood, in the case of generating an index image of an image data having an original image size larger than a standard size, a rate of reduction to the original image is increased so that the entire index image is accommodated in an index image display area while maintaining a relative dimensional relationship with index image sizes of image data having other original image sizes.

摘要:
A digital signal processor performs a predetermined operation on a digital signal based on data, such as coefficient parameters and programs, and outputs the processed digital signal to an external reproducing device. The digital signal is processed during a signal processing period and data is transferred and rewritten during an information transfer period. The digital signal processor generates a reference processing cycle having a period longer than the signal processing period and the information transfer period combined. The length of the signal processing period and the information transfer period are adjusted within the reference process cycle, and the signal processing and data transfer are performed in a time sharing manner via a common internal bus. When data is changed, the digital signal is outputted without being processed to an external reproducing device to maintain the continuity of the signal output. As a result, data required for the signal processing can be replaced without interrupting the output of the signal.

A laser recording apparatus has an image control circuit which allows for vertical or horizontal straight lines to be printed in spaces between lines without increasing the capacity of the memory region of the memory means of the apparatus. The image control circuit includes memory for storing character data, character patterning circuitry for converting the character data into character patterns which have memory regions for storing character data, control circuitry for reading character data stored in the peripheral portions of the memory regions to read such character data as straight lines in the spaces between character patterns and a central processing unit to control the various circuitry.

The active vibration-isolating device of the invention is used for preventing vibrations due to ground motions or running of an automobile from being propagated to a platform which is disposed in, for example, a semiconductor device factory or a laser device factory, and on which various kinds of equipment are to be mounted, and also from causing the platform to vibrate. The device has: an air spring which elastically supports a platform; a piston-like member which abuts against and supports the platform; plural piezoelectric actuators which can be externally controlled; a working fluid such as an aqueous solution of ethylene glycol which transmits driving displacements of the piezoelectric actuators to the piston-like member via piston members which are respectively fixed to ends of the piezoelectric actuators in a driving direction x; and a fluid path in which the working fluid is hermetically filled. The load of equipment mounted on the platform is shared by the air spring and the piston-like member, thereby enabling the spring rate to be reduced. Therefore, the resonance frequency can be set lower. As a result, vibration-isolating performance and vibration-damping performance can be surely adequately exerted on vibrations in a wide frequency range including a low-frequency region, and a wide load range.

A document reading device comprising a document stand having a document placing surface and an optical reading means for optically reading the surface of a document placed on the document placing surface. The device further comprises a guide member defining a guide passage extending in a direction toward and away from the document placing surface, an oscillating member mounted such that its one end can reciprocate freely along the document placing surface in a predetermined scanning direction and in a direction opposite to it and the other end can freely reciprocate along the guide passage, and a driving source for oscillating the oscillating member which is capable of moving said one end of the oscillating member at a substantially constant speed in the scanning direction. The optical reading means is provided in the oscillating member. While said one end of the oscillating member is moved in the scanning direction at said substantially constant speed, the optical distance between the surface of the document placed on the document placing surface and the optical reading means is maintained substantially constant, and the optical reading means scans the surface of the document.

A computer graphics apparatus is constructed for presenting on a display device a motion of an object defined by a plurality of articular segments manipulatable according to state values thereof. In the computer graphics apparatus, an input device has a plurality of control units, each of which is operable for time-sequentially inputting a control amount. An assignment device provides assignment information which defines correspondence between the control units of the input device and the articular segments of the object. A function device provides a functional parameter which defines a relation between the control amount of each control unit and the state value of each articular segment when the correspondence is defined between each control unit and each articular segment according to the assignment information. The function device further operates based on the functional parameter for converting the control amount time-sequentially inputted by each control unit into a time-series of the state value of each articular segment. A graphic device graphically manipulates each articular segment according to the time-series of the state value to present the motion of the object on the display device.
