Provided is an image reading apparatus that can read an image with highly accurate and stable density and color while illuminating the image with a color sequential projector thereof. The image reading apparatus according to the present invention includes: an image pickup unit configured to image an original that is mounted on a mounting surface; a projecting unit configured to project an image on the mounting surface by sequentially switching and emitting light of a plurality of colors; and a control unit configured to control the projecting unit so as to project a first black image, a first color image, and a second black image in this order during the imaging by the image pickup unit.

In one embodiment, a system includes a processor and logic executable by the processor. The logic is configured to cause the processor to: capture video data using a mobile device, the video data comprising a plurality of frames; determine whether one or more of the frames depict a document exhibiting one or more defining characteristics; determine whether one or more of the frame(s) determined to depict the document also satisfy one or more predetermined quality control criteria; and in response to determining one or more of the frames depict the document and also satisfy the one or more predetermined quality control criteria, automatically capture an image of the document. Corresponding computer program products are also disclosed.

An image forming apparatus includes: an image processor configured to perform first image processing on image data having a first resolution and to add tag data to a target pixel where second image processing is to be performed; a resolution converter configured to convert the image data into image data having a second resolution higher than the first resolution, and to perform the second image processing based on arrangement of the image data having the first resolution and the tag data; a pulse generator configured to generate an on-off modulation signal and an application-current switching signal in accordance with the image data having undergone the second image processing; and a light source driver configured to drive the light source in accordance with a current setting value output from an application current setter depending on the application-current switching signal and the on-off modulation signal.

A light-guide member includes a light-incident surface formed at an end portion of the light-guide member in a first direction, a light-emitting surface that is elongated in the first direction and that includes first and second light-emitting regions, which cause light to be emitted in different directions in a first cross section that is perpendicular to the first direction, a common deflecting portion that deflects light from the light-incident surface and causes the light to be emitted from the first and second light-emitting regions to the outside, and first and second protruding portions each of which is located on one of two sides of the deflecting portion in the first cross section, the first and second protruding portions protruding in a direction away from the light-emitting surface with respect to the deflecting portion.

The present disclosure relates an image correction apparatus and method. The image correction apparatus includes a printing unit for printing an image; a scratch detecting unit which detects a scratch region from a scan image scanned per line; and a restoration processing unit which performs the restoration of the scratch region by interpolation if the width of the scratch region detected by the scratch detecting unit is less than a predetermined value and, if the width thereof is not less than the predetermined value, does not perform a restoration of the scratch region but provides the printing unit with the scan image, thereby correcting an image distortion by easily detecting an image distortion due to foreign matter.

A image reading apparatus includes a first placement unit, a second placement unit, a first reading unit, a second reading unit, a rotating mechanism, and a switch-over mechanism that switches over the first placement unit and the second placement unit between a horizontal state and an inclined state. The rotating mechanism rotates the first reading unit and the second reading unit, so that, in the horizontal state, the first image reading unit and the second image reading unit read a medium placed on the first placement unit and a medium placed on the second placement unit respectively, and, in the inclined state, the first image reading unit and the second image reading unit read a medium placed on the second placement unit and a medium placed on the first placement unit respectively.

The presently disclosed inventive concepts encompass capturing video data using a mobile device, streaming the captured video data to a server for processing of the video data in real-time or near-real time, and providing the server's processing result to the mobile device for additional analysis and/or processing of the captured video data, the processing result, or both. In one embodiment an image processing server is configured to: process, in real time, input streamed to the server from a mobile device, the input comprising one or more frames of digital video data; and output a result of processing the input to the mobile device. In another embodiment, a method includes capturing video data using a mobile device, streaming the video data to an image processing server, receiving a processing result from the server, and further processing the captured video data and/or the processing result using the mobile device.

In one embodiment, a system includes a processor and logic executable by the processor. The logic is configured to cause the processor to: capture video data using a mobile device, the video data comprising a plurality of frames; determine whether one or more of the frames depict a document exhibiting one or more defining characteristics; determine whether one or more of the frame(s) determined to depict the document also satisfy one or more predetermined quality control criteria; and in response to determining one or more of the frames depict the document and also satisfy the one or more predetermined quality control criteria, automatically capture an image of the document. Corresponding computer program products are also disclosed.
