METHOD OF PRODUCING IMAGES AND LINEAR-SENSOR CAMERA

摘要

The invention relates to linear-sensor cameras, intended for observing scenes by scanning, the scene sweeping past the camera. The sensor (IMS) provides for each image point observed an output level (Ss) representing the illumination of this point over an effective integration duration Ti that may vary, the camera comprising a synchronisation input for receiving a relative sweep rate information item, means for establishing an image line reading cycle period TL inversely proportional to the relative sweep rate, and means of receiving a desired integration duration value TiD. The method is characterized in that, in at least a first mode of operation where the effective integration duration Ti is equal to the reading cycle period TL, the camera provides for each image point an illumination measurement level (Sc) which is proportional to the output level of the sensor multiplied by the ratio between the desired integration duration TiD and the line reading cycle period TL. Application: industrial control
