According to one embodiment, a decoloring device includes a reading unit, a decoloring unit, and a control unit. The reading unit is configured to read control information from a first image formed in a predetermined area of a sheet. The decoloring unit is configured to decolor a portion or entirety of a second image, different from the first image, formed on the sheet using a decolorable recording material. The control unit is configured to control erasing of the data of the second image from a storage device, based on the control information, in a case where the decoloring unit decolors the second image.

This disclosure describes a distributed reader architecture for a mobile computing device such as cellular telephone handset. One claim recites a portable computing device including: memory for storing a library of processing components, the library including a signal detector component and an audio fingerprinting component; a microphone for capturing ambient audio; one or more processors configured for: invoking the audio fingerprinting component for processing captured audio to produce an audio fingerprint, wherein the audio fingerprinting component comprises a filtering process, in which the filtering process produces components of the captured audio that are used to produce the audio fingerprint; and invoking the signal detector component, in which the signal detector component comprises a fast detect process for analyzing the captured audio to determine the presence of an auxiliary signal within the captured audio, and when the presence of the auxiliary signal is detected, controlling the signal detector component for detecting the auxiliary signal to yield a detected auxiliary signal. The device further includes a communications output for communicating the audio fingerprint and the detected auxiliary signal to a remotely located server. Of course, other claims and combinations are provided as well.

A technology that enables accurate position specification on an image displayed on a screen to perform processing and correction of the image data is provided. When the image is printed on a sheet on which a dot pattern is printed, a reference point of the image on the display device is set and the reference point is printed in a visible mark together with the image. This mark is imaged with an imaging means, and calibration is performed in which position coordinates of the marks on the sheet and the reference points of the image are matched, thereby preventing variation in coordinates between designation made on the sheet with the imaging means and processing on the image.

An image scanning device includes a detector and a setter. The detector scans an image in units of pages, and detects a code image included in the image in units of pages. When the detector detects the code image on one page and then detects the code image on another page, the setter sets a scanning area on a subsequent page following the other page in accordance with a position of the code image detected on the one page and a position of the code image detected on the other page.

Methods and systems permit a user to decide what different responses are triggered when different visual stimuli are presented to the user's wireless communications device.

A system for capturing images during production of printed material includes an optical device comprising a plurality of cameras arranged in an array with adjacent pairs of cameras having overlapping fields of view. An imaging controller device determines a layout of content on printed material, and determines, based on the layout, an optical system configuration profile. Determining the optical system configuration profile includes selecting one or more cameras for capturing images of regions of interest on the printed material and determining a trigger interval for triggering the selected one or more cameras. The imaging controller device triggers the selected cameras at times determined based on the trigger interval to capture images of the regions of interest on the printed material as the printed material moves in fields of view of the one or more cameras during production of the printed material.
