Abstract: This invention relates to a conversion table compression method of compressing a conversion table and storing the conversion table in a storage medium, including an axial difference creating step of creating an axial difference table by calculating, from data stored in the conversion table, the difference values between grid points adjacent in predetermined directions along a plurality of axes which define the input space of the conversion table, a compressing step of compressing the axial difference table to create compressed data, and a storing step of storing the compressed data in a recording medium.

Abstract: An electronic device which is capable of performing high-accuracy remaining battery capacity management. The electronic device has a plurality of battery pack compartments assigned specific addresses, respectively. A remaining capacity-detecting unit detects the remaining battery capacity of a battery pack mounted in a battery pack compartment. A control microcomputer receives information indicative of a remaining battery capacity sent from a battery pack accommodated in one of the battery pack compartments and address information on the battery pack compartment, and sends correction information concerning the remaining battery capacity to the battery pack.

Abstract: This invention can reduce the load on a recording apparatus, efficiently design the overall system, and accurately calculate a data amount recordable on a recording unit in accordance with setting change of each communication apparatus or the like. A portable remote storage transmits information on a data amount strorable in the portable remote storage to digital cameras. The information on the data amount storable in the portable remote storage is based on the remaining area of a shared storage area commonly available for the digital cameras except for an exclusive storage area assigned to each digital camera.

Abstract: An image communication apparatus converts image data received through a communication line into bit image data to be reproduced as a visible image by means of using a data converting unit and a reproducing unit. The apparatus converts data from a data processing apparatus into bit image data to be reproduced as a visible image by means of using the data converting unit and the reproducing unit, so as to accomplish an efficient system as a whole.

Abstract: An image processing system in which image data is generated in an offset sampled structure using a two-dimensional sensor. The generated image data is separated into a plurality of sets of image data having a lattice arrangement, and each of which has the same color. One set of the image data is coded in accordance with a first coding parameter, and another set of the image data is coded in accordance with a second coding parameter. The two sets of coded data are then stored in a memory for subsequent transfer to an image output device.
