Zusammenfassung: | PROBLEM TO BE SOLVED: To reduce the amount of memory that temporarily holds image data.SOLUTION: A memory control circuit comprises: a writing part that receives an input of image data read by a reading device, requests writing of the image data in a memory, and writes the image data in the memory; and a reading part that reads the image data written in the memory and transfers the read image data to a subsequent stage. The writing part averages the frequency at which the writing is requested in a line period indicating a period during which the reading device reads one line of image data in a main scanning direction.SELECTED DRAWING: Figure 1
【課題】画像データを一時的に保持するメモリの容量を削減することを目的とする。【解決手段】読取装置により読み取られた画像データの入力を受け付けて、メモリに対する前記画像データの書込要求を行い、前記メモリに前記画像データを書き込む書込部と、前記メモリに書き込まれた画像データを読み出して、読み出した前記画像データを後段へ転送する読出部と、を有し、前記書込部は、前記読取装置が主走査方向に1ライン分の画像データを読み取る期間を示すライン周期において、前記書込要求が行われる頻度を平均化する。【選択図】図1 |
