Frequency content motion detection is performed by decomposing a raw field luminance data in to a number of frequency content sub-bands, detecting motion using the raw field luminance data in parallel with the decomposing, generating a motion correction value by multiplying absolute values of the sub-bands by weighting factors, and applying the motion correction value to detected motion. When a log-full condition is detected, the active transaction having the oldest log entry of all active transactions is identified and logging for all transactions except for the identified transaction is temporarily suspended. A main heat conductor is in thermal communication with a first defined portion of a length of the detector module, and a local heat conductor is in thermal communication with a second defined portion of the length of the detector module. The translation header provides the user with an option of translating the document text or portions of the document text to the user’s preferred language. Each sucking hole of the sucking unit is formed by a through hole section communicating with the decompression chamber and a sucking chamber having a larger area of a sucking surface opposed to the recording medium than a sectional area of the through hole section.
