ABSTRACT:
A block copy image is divided into several regions R1 and R6, to which different system colors are allocated. A subject region PR including a line break CP1 is specified by an operator. Run-length data of a run-length less than or equal to a predetermined threshold value is automatically detected out of various run-length data representing the subject region PR. White/black designation data defining the color of an image in the run-length data is changed into the color of a linework. The break CP1 in the linework is thus reconnected without operator's instruction. Alternatively, the subject region PR is divided into two portions. The two portions are further divided into separate areas to which different system colors are allocated. This enables an operator to easily detect the position of a line break because the linework elements separated by a break have different colors. The break is then reconnected according to operator's instruction.
