  • Patent number: 8593699
    Abstract: According to one embodiment, an image sensor module including a plurality of image sensors and a common signal line. The common signal line is commonly electrically connected to the plurality of image sensors. To the common signal line, image signals are output sequentially from the plurality of image sensors. The image sensor module feeds back a feedback signal from a first image sensor to a predetermined image sensor. The first image sensor is an image sensor which lastly outputs the image signal among the plurality of image sensors. The predetermined image sensor is an image sensor which outputs an offset signal to the common signal among the plurality of image sensors. The feedback signal indicates a completion of an output of image signal to the common signal line. The predetermined image sensor outputs the offset signal to the common signal line in response to the feedback signal.

  • Patent number: 8582182
    Abstract: A computer peripheral that may operate as a scanner. The scanner captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. As additional image frames are added to the composite image, the size and format of the composite image may be automatically adjusted to facilitate ease of use.

  • Patent number: 8564848
    Abstract: On a bottom surface of a light guide element of an operation device including a panel with a light-transmissive portion, a reflection portion is formed in a first region thereof, which is close to a light source, and a first diffusion surface is formed in a second region of the bottom surface of the light guide element, which is a region distant from the light source. A light-incident side of the light guide element is a non-diffusion surface. Sides other than the light-incident side are second diffusion surfaces. Light that has been emitted from the light source and incident to the light guide element via the light-incident side is totally reflected and is then guided to the first and the second diffusion surfaces and a part of diffusion-reflected light illuminates the light-transmissive portion of the panel.
