摘要:
A color image processing apparatus comprises a printer for printing an image corresponding to an original image scanned by an scanner. An image memory is provided into which signals from the color scanner respectively corresponding to plural colors are written and from which signals to be transmitted to the printer are read. The image memory is arranged such that a signal for a writing operation and a signal for a reading operation are substantially simultaneously input. A memory control unit addresses the image memory in either the writing operation or the reading operation. The memory control unit comprises a writing address counter, a reading address counter and a control means. The control means controls the writing address counter and the reading address counter such that image data is read from the image memory before the writing of the image data into the memory is completed.

There is provided a color image processing apparatus comprising color conversion circuit for converting image data to a desired color, feature extraction circuit for extracting a feature of the image data and image correction circuit for correcting the image data on the basis of the feature extraction circuit, characterized in that a color conversion processing is executed prior to extraction of feature from the image data.
摘要:
An image forming apparatus arranged to receive image information from a memory device for storing color image information and then to form an image on an image-forming medium. This apparatus allows an operator to specify the size and the layout of a color image to be formed on the image-forming medium while viewing a display provided on a monitor device. The apparatus can change the size of the color image information read from the memory device to the required magnification in accordance with a command given by the specifying element, thereby producing a printout. In this case, the operator can adjust the image quality of image information to be printed out while visually confirming the quality of the image displayed on the monitor device, whereby no proof printout is needed.
摘要:
An edge portion of an achromatic area is detected to emphasize the edge portion and reduce the density of a chromatic area near the edge portion, and the reduced chromatic portion signal is further suppressed, such that the half tone area can be processed at high gradation and the black character and line image can be outputted with more black and high resolution, resulting in less color bleeding.

An image data monitor apparatus has a CCD for reading image data of a document, an input buffer for receiving the pixel data from the CCD, an image processor for processing the data received from the CCD for printing out an image or the like, a circuit including a counter for extracting the designated pixel data, a keyboard for setting a desired mode, LEDs for displaying the extracted pixel data and other data, and a CPU for controlling the operation of the overall system. Various data such as maximum and minimum values of, an average value of or a maximum difference between the pixel data can be monitored at high speed upon selecting a corresponding mode. Desired data processing can be performed based on the monitored data.

摘要:
An electrically driven linear actuator (1) has an electric motor with a ball screw mechanism (3 and 4) connected to an output shaft (2a) of the electric motor (2), via a power transmitting mechanism (10 and 12) to convert a rotary motion of the electric motor (2) to a linear motion of an object member to be controlled by the actuator (1). Housing members (5, 6 and 8) contain the ball screw mechanism (3 and 4) and the power transmitting mechanism (10 and 12). Stroke end members (14 and 14), of a ball screw shaft (4) or a ball screw nut (3) forming the ball screw mechanism (3 and 4), are rotatably supported relative to the housing members (5 and 8) via a free rotation mechanism (20 and 20).
