Abstract: PROBLEM TO BE SOLVED: To obtain an image reading device which is able to suppress deterioration of read quality, even when the relative positional deviation of a light receiving member and a lens array is different for each light-receiving member. SOLUTION: Prior to reading of a document sheet member P, a light source irradiates a reference white board 65 with a light, and a detection unit 80 acquires periodic unevenness of the light from the reflected light thus detecting the relative positional deviation of the light receiving member 72 and the lens array 70. Based on the positional deviation, a correction unit 82 selects the shading correction data which are suitable for each light-receiving member 72 from a plurality of kinds of shading correction data stored in a memory unit 78. The correction unit 82 corrects the electrical signal on the rear surface of the document sheet member P, which is read by the light receiving member 72 and is converted, based on the selected shading correction data. Consequently, deterioration in the reading quality can be suppressed, even when the relative positional deviation of the light-receiving member and the lens array is different for each light-receiving member.

Abstract: Methods and systems are disclosed for determining at least one actuation characteristic of an imaging device. For example, one method includes determining a target distance to move a lens by an actuator to focus a scene on an image sensor, where moving the lens by the actuator causes an associated lens vibration having at least one actuation characteristic, determining a scan sequence having a plurality of successive measurements, each measurement having at least a first measurement parameter and subsequent measurement parameter, each measurement parameter including at least one step and at least one time delay, moving the lens the target distance for each successive measurement based on the measurement parameters of each successive measurement, measuring a performance indicator of each successive measurement, and determining at least one actuation characteristic based on the first measurement parameter of the measurement having the highest performance indicator.

Abstract: Methods and systems are disclosed for damping unwanted vibrations or ringing of a lens in an imaging device. For example, one method includes determining a target distance to move a lens, and dividing the target distance into multiple steps having at least a first step and a subsequent step, moving the lens, via an actuator, by the first step, thereby causing a first vibration, retrieving a damping parameter indicative of a time delay, the damping parameter being based on at least one characteristic of the actuator and the number of steps, and repeating said moving the lens at least one subsequent step after delaying the subsequent step by one of the damping parameters, each moving the lens a subsequent step causing a subsequent vibration, and the damping parameters affecting the vibration such that the first and subsequent vibrations at least in part modify each other to lower overall vibration.
