    摘要： An image recording apparatus using a plurality of recording heads that can prevent black lines from occurring at scanning boundaries of the recording heads. The total recorded ink volume at the boundaries is positively reduced so that the black lines and the overflow of ink are prevented. The apparatus includes at least a pair of a dark head for discharging relatively dark ink and a light head for discharging relatively light ink. The apparatus separates an input image signal into image signals applied to the dark and light heads using at least two tables. The two tables, one for edge nozzles of each recording head and the other for the remaining nozzles, separate the input image signal independently so that the total ink volume discharged from the edge nozzles are limited to a relatively small amount. Further, the total volume of ink discharged from the edge nozzles of the recording heads are positively reduced by performing black abstraction processing, UCR processing and black inking processing on the basis of the image signals after the separation by the tables, which image signals linearly correspond to the ink volume.

    摘要： A recording apparatus includes a recording head having plural recording heads, a test pattern recorded for recording a test pattern, a read-out for reading out the test pattern which was recorded by the test pattern recorder, a correction data setting device for setting shading correction data used when the recording head records based on the read-out data from the read-out, and a modification device that modifies the test pattern recorder and/or the correction data setting device in response to at least one of a recording mode of the recording apparatus, the state of the recording head, or the state of the test pattern recorder. Alternatively, the recording head can be driven by comparing identification information read out from a second memory with recording head identification information stored in a first memory, and selectively driving the recording head using second shading correction data read out from the second memory or first shading correction data read out from the first memory, depending upon whether two types of recording head identification information are equal.

    摘要： An apparatus for transmission, reception and recording of an image, such as a facsimile apparatus, capable of correcting the unevenness in density or improper density resulting from fluctuation in the performance of the recording head of the receiving unit, with a limited amount of data transfer. At the start of communication, correction data for uneven or improper density of the recording head are sent from the receiving unit to the transmitting unit. The transmitting unit corrects the multi-value image data to be transmitted, based on the received correction data, and sends the corrected image data after conversion into binary state. The receiving unit receives the binary image data and effects image recording. The time and cost for data transmission can be reduced, as the correction is conducted at the transmitting unit and the data transmission can be made in binary data.

    摘要： An image forming apparatus is provided by which a certain test pattern is recorded with a recording head having a plurality of recording elements, and the degree of density unevenness of each recording element of the recording head is calculated by reading the test pattern. The temperature of the recording head is detected and the degree of density unevenness calculated is corrected according to the detected temperature, thereby calculating correction data with respect to each recording element. At the time of image recording, image data input for each recording element is changed based on the correction data to correct any unevenness in density of the recorded image.
