摘要： An image recording apparatus and method performs recording by making an ink adhere to a recording medium according to the blot ratio of a recording medium, when using an ink droplet or heat sensitive ink. Input recording data is discriminated based on a predetermined reference value based on the blot ratio and when the image data is larger than the reference value, the image data is reduced in order to reduce the ink dot size. Reducing the ink dot size at a recording boundary improves the quality of the image recorded at the recording boundary.

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： 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.
