  • Patent number: 9360316
    Abstract: A line scanner scans in a cross track direction and moves forward on a platform in an along track direction. The line scanner includes a plurality of detectors forming a left array and a plurality of detectors forming a right array. The left array and the right array are tilted away from a line formed in the along track direction. The left array is configured to detect scene radiance from a surface of an object when the line scanner is scanning the surface on the right side of the line formed in the along track direction. The right array is configured to detect scene radiance from the surface of the object when the line scanner is scanning the surface to the left side of the line formed in the along track direction. The detectors in each respective array are configured to simultaneously detect the scene radiance.

  • Patent number: 9325875
    Abstract: A reading control apparatus that causes a reading apparatus including a light source and a sensor configured to receive light reflected by an original, to read the original, executes control for changing the irradiation angle of the light source with respect to the original. The control is executed to change the irradiation angle for one light source. Read images of the original corresponding to respective changed irradiation angles are acquired based on reflected beams that correspond to the respective irradiation angles and have been received by the sensor. The region of a correction target on the original is detected based on the acquired read images.

  • Patent number: 9308390
    Abstract: A device for treating an area of skin by scanning radiation to form a pattern of treatment spots on the skin may include a radiation source that generates an input beam, and a scanning system that scans the input beam to provide a sequential series of reflected output beams that form a pattern of treatment spots on the skin. The scanning system may include a rotating scanning element including a plurality of reflection surfaces, each configured to reflect the input beam in an angular direction to provide one of the reflected output beams, such that as the rotating scanning element rotates about an axis, the input beam is sequentially reflected by different reflection surfaces to provide the sequential series of reflected output beams, wherein a first reflection surface is offset from a second reflection surface in a direction generally along the axis of rotation of the rotating scanning element.

  • Patent number: 9247253
    Abstract: A video encoder may use an adaptive Wiener filter inside the core video encoding loop to improve coding efficiency. In one embodiment, the Wiener filter may be on the input to a motion estimation unit and, in another embodiment, it may be on the output of a motion compensation unit. The taps for the Wiener filter may be determined based on characteristics of at least a region of pixel intensities within a picture. Thus, the filtering may be adaptive in that it varies based on the type of video being processed.
