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： A thermal head drive circuit with the input connected to a source of printing data and the output connected to a thermal head including heater elements, so as to improve the picture quality of a thermal head recording apparatus for printing successive lines. Improved picture quality is effected by using data from previously printed lines to compute a corrected pulse energy for the line being printed. The circuit uses a heat storage state operator for operating the heat storage state of each of the heater elements constituting a thermal head, a pulse energy operator for computing a printing pulse energy to be applied to each of the heater elements, a memory for storing the electrical pulse energy used in the previously printed line, and a counter to count the number of dots on the line to be printed. The pulse energy operator uses data from the heat storage state operator, the counter, and from the memory which has data on the pulse energy used in previously printed lines. The output of the pulse energy operator is connected to a pulse generator which is used to drive the heater elements of a thermal head.
