Abstract: An example method includes displaying, by a graphical user interface of a computing device, an image comprising a target region. The target region may be smaller than an entirety of the image. The method includes providing, by the graphical user interface, a user-adjustable control to adjust a desired local brightness exposure level for the target region. The method includes receiving, by the user-adjustable control, a user indication of the desired local brightness exposure level for the target region. The method includes adjusting the local brightness exposure level for the target region in the image in response to the user indication.

Abstract: The present application discloses a display device. In the display device provided by the present application, by making the refresh frequencies correspond to the white balance look-up tables and the gamma voltages, when the refresh frequencies of the display panel change, the brightness of the images of the display panel can be adjusted by adjusting the white balance look-up table and the gamma voltage provided to the display panel.

Abstract: An apparatus includes an imaging unit configured to capture an image of a subject formed on a surface having an array of a plurality of pixels, an acceptance unit configured to accept a designation of a pixel or a region including a plurality of pixels on the surface, a determination unit configured to determine an exposure of the pixel or the accepted region to have a predetermined luminance, and to determine an exposure of other pixels or other regions according to a distance from the pixel or the accepted region on the surface, and an output unit configured to output an image signal captured by the imaging unit at the determined exposure.

Abstract: An imaging device including a control unit configured to: display a pre-capture screen for white balance data capture; display a confirmation screen displaying a captured value after capture subsequent to the pre-capture screen; and perform display control of transitioning to an adjustment screen for adjustment of the captured value, according to a user's operation on the confirmation screen.

Abstract: An illumination condition, which is used to irradiate a print product with light having illuminance higher than normal illumination, is derived based on exposure condition information at the time of photographing.

Abstract: The various embodiments herein relate to imaging devices and systems that capture an image of a target object and separately capture light from the light source illuminating the target object to compensate for inconsistent lighting of that object. Some systems have scene cameras to capture the images of the target objects and a separate light capturing camera to capture the light from the light source. Other embodiments relate to a single camera capturing an image of the target object while simultaneously capturing light from the light source.

Abstract: There is provided a method and apparatus for tracking eyes of a user. The method and apparatus may acquire an image of the user, acquire an illuminance of a viewpoint from which the image is captured, and output coordinates of the eyes tracked from the image by operating at least one of a high illuminance eye tracker that operates at a high illuminance or a low illuminance eye tracker that operates at a low illuminance based on the acquired illuminance.

Abstract: An image forming apparatus, including: a first reading section which emits visible light to a sheet having an image formed thereon, receives light from the sheet and outputs a read signal having an intensity corresponding to an amount of the received light; a second reading section which emits light including at least ultraviolet light to a ground region of the sheet, receives light from the sheet and outputs a read signal having an intensity corresponding to an amount of the received light; and a correction section which corrects the read signal output from the first reading section by using the read signal output from the second reading section so that a color reproduced by the read signal output from the first reading section is consistent with a color observed by a user.

Abstract: An image capturing device with automatic white balance and an automatic white balance correction method are provided. The image capturing device includes a lens assembly, a light diffuser, an image sensor and a processor. The relative position of the light diffuser and the lens assembly is fixed. The processor is electrically connected to the image sensor having a first sensing region and a second sensing region. The light diffuser converts a fraction of the incident light to the reference light. The first sensing region converts the incident light to the display image information. The second sensing region converts the reference light to the correction information. The processor determines a reference gain average according to at least one color gain of the correction information and obtains at least one color gain correction value according to the reference gain average to adjust the white balance setting of the display image information.

Abstract: A first acquiring unit acquires a background image being an image of a usage environment in which a printed material is used, a lighting image of a lighting installed in the usage environment, and light source information indicating an optical attribute in the usage environment. A second acquiring unit acquires print data. A display control unit displays a preview image on a display unit, where the preview image is an image in which a printed material image is superimposed on the background image, and the printed material image is an image in which the lighting image is mapped by environment mapping onto a print-image display surface generated based on the print data and in which the optical attribute specified by the light source information is set.

Abstract: An image processing apparatus includes: an obtaining member to obtain an image; a copying member to copy the image obtained by the obtaining member; a detecting member to detect a face area from the copied image or the obtained image; a correcting member to perform correction to adjust a brightness and a color shade of a whole of the obtained or copied image from which the face area is detected by the detecting member so that a flesh color component of the face area detected by the detecting member is corrected to become a predetermined status; and a synthesizing member to make a transparency of the face area detected by the detecting member different from another area and to synthesize the image corrected by the correcting member and the obtained or copied image from which the face are is not detected by the detecting member.
