摘要:
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.

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.

A laser recording apparatus wherein an image is recorded by laser beam scanning, and a stop amount of a stop is varied in accordance with recording magnification. The stop is disclosed at a position whereat it can vary the beam radius of a laser beam incident in a focusing lens. The optical intensity of a laser beam is varied in accordance with the recording magnification.

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.
摘要:
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.
摘要:
A calibration method having the steps of: forming a test image on a sheet; reading the test image on the sheet; and determining correction data to converge data of the test image onto target data, based on information read in the reading step; wherein in cases where in the step of forming the test image a first test image is formed on a face of a transparent sheet as the test image, in the step of reading the test image the first test image is read from a first side of a face to be read which is opposite to the face of the transparent sheet where the first test image is formed.
摘要:
An image forming apparatus having: a plurality of scanners, each of the scanners having a rotary polygonal mirror; a position detecting section for generating an image start reference signal in a main scanning direction; a PLL control section for controlling a rotation number of the mirror on a basis of a reference frequency signal of the mirror and a pulse signal generated per one rotation of the mirror; and a phase control section for detecting phase difference of each mirror on the basis of the image start reference signal in the main scanning direction in the plurality of the scanners, controlling a phase of the reference frequency signal of each mirror, and correcting image deviation in a sub-scanning direction of an image formed by the plurality of the scanners. A control angle in which one rotation angle of the mirror is divided by a number of the pulse signal generated per one rotation of the mirror is equal to an integral multiple of a division angle in which one rotation angle of the mirror is divided by a number of mirror faces of the mirror.
摘要:
In a projection display device, a main board that is substantially perpendicular to a plane defined by optical axes of an optical unit is allowed to stand aside the optical unit. Therefore, if the main board is designed to have a small vertical size, the vertical size, i.e., the thickness of the projection display device, can be reduced. Therefore, unlike the conventional projection display device in which the main board is disposed above the optical unit, the entire device can be reliably reduced in thickness and size regardless of the thickness of the main board.
