A method and apparatus for performing color image processing includes inputting a standard color image signal, performing color correction on the standard color image signal using a predetermined parameter to produce a color-corrected standard color image signal, and encoding the color-corrected standard color image signal to produce an encoded standard color image signal. The encoded standard color image signal is decoded to produce a decoded standard color image signal. The predetermined parameter is determined on the basis of both the standard color image signal and the decoded standard color image signal.

Color image processing method and apparatus which calibrates correction

In color image communication between different kinds of apparatuses, an output image which accurately reproduces a transmitted original image is obtained by individually providing color correction units in apparatuses at the transmitting side and the receiving side and by obtaining color correction parameters in accordance with a predetermined or standard color image.

Color image processing apparatus having transmitter and receiver which

A communication apparatus includes a data communication unit; a speech communication unit; a connection unit for connecting to a plurality of lines; and a switching unit for selectively connecting the data communication unit and the speech communication unit to any one of the plurality of lines. Both speech and data communication units may be used concurrently. The communication apparatus further includes a memory unit for storing line information identifying a line different from another line in use for data communication or speech communication. An automatic calling to both speech and data communication units may be effected by a single calling operation by the operator.

Data communication apparatus for data and/or speech communication on a

A recording apparatus has a plurality of erasing heads arrayed aslant to the direction in which a strip-like recording medium is to be transported. An erasing operation on recorded information on the recording medium obliquely begins and obliquely ends by switching the erasing heads on and off one after another along an oblique recording track on the recording medium to accomplish information editing without introducing noises.

Recording apparatus

A display panel comprising a liquid crystal device comprising a plurality of picture elements arranged in a plurality of rows and columns, each picture element comprising a ferroelectric crystal under bistability condition showing either a first or a second orientation state; means for orienting the ferroelectric liquid crystal to either one of the first and second orientation states at respective picture elements; and means for controlling the duration of the first or second orientation state at respective picture elements.
