发明名称 IMAGE PRINTER
摘要 PURPOSE:To prevent the lowering of density on the boundary of blocks by performing a printing based on a density data obtained by multiplying heat generating elements at the end of each block by a correction factor when a number of the heat generating elements of a line printer head are driven as divided into a plurality of blocks. CONSTITUTION:An image input section 6 converts an image signal into a contrast data to be inputted into a CPU7. The CPU7 converts the contrast data into a data with the pulse width for driving heat generating elements to be outputted to a line memory 9. At this point, the contrast data corresponding to the boundary of blocks of the heat generating elements is referred to a correction factor section 8 and results in a contrast data multiplied by corresponding correction factors.
