Abstract: A trajectory generation management unit determines a target foreground object based on a user's input operation for selecting a target foreground object. The trajectory generation management unit determines a time range to generate a trajectory image based on the user operation. A trajectory calculating unit calculates a trajectory of the target foreground object in the determined time range. A virtual viewpoint determining unit determines virtual viewpoint information based on the trajectory. An image generating unit determines plot times in the time range based on a user's plotting operation. The image generating unit generates a trajectory image based on the determined plot times.

Abstract: An image processing apparatus for controlling at least one, of a plurality of image capture apparatuses, the plurality of image capture apparatuses arranged to capture a plurality of images for generating a virtual viewpoint image, the image processing apparatus comprising: a determination unit configured to determine a region of interest in at least one image captured by the at least one image capture apparatus; and a control unit configured to control, if based on the determined region of interest it is determined to adjust an image quality of another image to be captured by the at least one image capture apparatus, the at least one image capture apparatus so that the image quality of the other image to be captured thereby is adjusted.

Abstract: An information processing apparatus includes a reception unit configured to receive a designation of a virtual viewpoint relating to a virtual viewpoint image, and a display control unit configured to display a virtual viewpoint image which is generated based on images obtained by shooting an imaging target area from a plurality of directions using a plurality of imaging apparatuses and corresponds to a virtual viewpoint according to the designation received by the reception unit, and information, which specifies a target object included in a range of the field of view of a virtual viewpoint different from the virtual viewpoint according to the designation, on a display unit, wherein the target object is in the imaging target area.

Abstract: An image forming apparatus has a sheet feeding portion which feeds a topmost sheet of sheets stacked on a sheet stacking portion and an image forming portion which forms an image to the sheet fed by the sheet feeding portion. The image forming apparatus also has a moisture-proof member set to a covering position so as to contact with and cover a topmost sheet of sheets stacked on the sheet stacking portion, a moisture-proof member detection portion which determines whether the moisture-proof member is available at the covering position, and a notification portion which notifies the presence or absence of the moisture-proof member at the covering position based on a detection result from the moisture-proof member detection portion.

Abstract: The invention is directed to providing a sheet feeding apparatus including a stop mechanism configured to stop a sheet storage unit while the sheet storage unit is being drawn out from an apparatus main body, a stop release mechanism configured to release stop of the sheet storage unit by a stop mechanism and to enable detachment from the apparatus main body, a holding mechanism configured to hold a release state using the stop release mechanism of the stop of the sheet storage unit by the stop mechanism, and a return mechanism configured to release the holding of the release state of the stop mechanism by the holding mechanism while the sheet storage unit is being attached to the apparatus main body, and to return the sheet storage unit to a stop state using the stop mechanism.

Abstract: In a sheet processing apparatus, a pair of regulating members is provided at a pair of joggers so that the regulating members are movable together with the joggers. When the pair of joggers is laterally moved, the pair of regulating members also laterally moves together with the pair of joggers. By moving the pair of joggers to passage positions, the pair of regulating members regulates the lateral ends of a sheet, which falls and is stacked on a first stacking tray.
