Abstract | To provide a reader which can suppress reduction of the quality of an image and a method for controlling the reader.SOLUTION: A reader 11 includes: a reading unit 25 for reading a manuscript; and a control unit 31 for executing calibration and calibrating the reading unit on the basis of the calibration data obtained by the calibration. The control unit executes calibration when the amount of external light is not larger than a threshold value, calibrates the reading unit on the basis of first calibration data 38 obtained by execution of calibration, and calibrates the reading unit on the basis of second calibration data 39 different from the first calibration data when the amount of external light is larger than the threshold value.SELECTED DRAWING: Figure 3
【課題】画像品質の低下を抑制できる読取装置及び読取装置の制御方法を提供する。【解決手段】読取装置11は、原稿を読み取る読取部25と、キャリブレーションを実行する制御部31であって、キャリブレーションを実行することによって得られる較正データに基づいて読取部を較正する制御部と、を備え、制御部は、外光の光量が閾値以下である場合に、キャリブレーションを実行し、キャリブレーションを実行することによって得られる第1較正データ38に基づいて読取部を較正し、外光の光量が閾値を超える場合に、第1較正データとは異なる第2較正データ39に基づいて読取部を較正する。【選択図】図3 |
