    摘要: An image reading unit has a line sensor for reading a document and producing image data. A line counter counts the number of lines that are scanned during a period from a start of reading by the image reading unit until a time point when an edge of the document is read. A ROM stores, in advance, a corresponding relationship between error accumulation values and the numbers of lines. A control section reads out, from the ROM, an error accumulation value corresponding to the number of lines counted by the line counter, and determines the position of the edge of the document in the auxiliary scanning direction by subtracting the readout error accumulation value from a product of the counted number of lines and the auxiliary scanning pitch, thereby detecting a document length in the auxiliary scanning direction.

    摘要: A image edit apparatus in which area data of 16-bit width have been stored at the memory locations of the corresponding addresses of the respective memory planes of a plane memory 403. The operation of reading area data therefrom by a pseudo sync signal starts before a line sync signal becomes active. A density-conversion/area generating circuit 405 converts the data format from the plane type to the pixel type, so that area commands are generated. Then, the circuit 405 reads an edit command out of a logic RAM, using the area command as address, and outputs the command. By reading the area data earlier and processing that data, a delay in the density-conversion/area generating circuit can be absorbed, so that the output edit command is synchronized with the image data.
