摘要： An image acquisition system configured to acquire an image of an object to be conveyed. The system includes a plurality of light sources configured to emit light rays with which the object is irradiated, a light source control unit configured to switch a light source that irradiates the object with the light among the plurality of light sources, and a line scan sensor configured to detect light from the object irradiated with the light. The line scan sensor has a pixel section in which a plurality of pixels are at least one-dimensionally arrayed and is configured to switch a gain value for amplifying a signal from each pixel. The line scan sensor switches the gain value in synchronization with the switching of the light source.

摘要： An image reading device includes a single light source that irradiates an image reading target with light, a traveling change member that changes a traveling direction of the light from the light source and irradiates the image reading target with the light at an incidence angle different from an incidence angle of the light directly applied from the light source to the image reading target, and a switching mechanism that switches traveling of the light from the light source to an optical path for directly irradiating the image reading target or an optical path for irradiating the image reading target via the traveling change member.

摘要： In a line sensor including color filters that are periodically disposed in a light-receiving-element row, a problem called a "mixture of colors" occurs. A "mixture of colors" occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element.
In a CMOS sensor 107 including a light-receiving-element row in which a plurality of photodiodes 1204 are disposed side by side in a main scanning direction and a plurality of color filters 1202 that are disposed in correspondence with the plurality of photodiodes 1204, the center of each color filter 1202 is displaced in a direction of the center of the light-receiving-element row from the center of the photodiode 1204 corresponding to the color filter.

摘要： Multifunctional display (2) including a display panel (4) and a sensing and emitting base (6), the display panel (4) comprising a body (9) forming a layer extending substantially between a viewing surface (10) that an observer can see, or against which an object (1) may be placed, and a base surface (14) facing the sensing and emitting base (6), and a plurality of optical paths (20) bounded by a light resistant material are formed within the body (9) extending between a base orifice (16) in the base surface (14) and a viewing orifice (12) in the viewing surface (10) for the passage of light between base orifice and the viewing orifice, the sensing and emitting base comprising at least one multi-color light source (28) positioned below or in the base orifice and at least one optical sensor (32) positioned below or in the base orifice. The display comprises a scanning function in which the sensing and emitting base is operable to emit light from the multi-color light source and simultaneously detect with the optical sensor the reflected light from a surface (3) of an object (1) placed on the viewing surface, and to compute with a microprocessor, an image of said surface based on the detected reflected light of a plurality of optical paths.
