Abstract: The inkjet recording apparatus includes a recording head, a cap member, a humidifying part for humidifying interior of the cap member, a cap moving mechanism, a controller, and a storage part. The storage part has stored a non-capping period table in which a number of vibrations of ink level within each nozzle is increased based on a non-capping period of an ink ejection surface, and a capping period table in which the number of vibrations is decreased based on a capping period of the ink ejection surface. In response to respective lengths of the non-capping period and the capping period from an end of ink ejection until a start of next ink ejection, the controller sets the number of vibrations at a start time of next ink ejection by using the non-capping period table and the capping period table.

Abstract: A color printing system manages ICC profiles by controlling ink use without performing the ICC profile creation operations. To obtain an ink limit for an ICC profile, a table associated with the ICC profile is parsed to determine the ink limit. The ink limit is decreased or increased. For an ink limit decrease, a color over the decreased ink limit is adjusted to meet the new ink limit. The ICC profile is updated accordingly. For an ink limit increase, the combination of primary colors are boosted by a percentage amount. Checks are made with regard to the volume-based ink limit and an quality check operation to accepted the boosted amount. The ICC profile is updated accordingly.

Abstract: A method includes generating multiple attention map for an image from outputs of a corresponding different one of multiple convolutional hidden layers of a neural network. A different weighted attention map is then generated from each of the attention map. The weighted attention maps are input to a first fully-connected neural network layer to generate a colorfulness metric, which may be used to augment human-perceived colorfulness of the image.

Abstract: A method is disclosed for calculating similarity rates between electronic documents. The similarity rate is calculated based on a count of matching phrases between the electronic documents and distances between subsequent matching phrases in each of the electronic documents. A system is also disclosed for comparing the electronic documents to obtain their similarity rates. A computing device determines at least one first proximity parameter based on the number of matched words in a matching phrase and at least one second proximity parameter based on distances between the subsequent matching phrases in each of the electronic documents. The similarity rate is determined based on the first and second proximity parameters.

Abstract: An operation device operated by a person includes an operation portion, an attachment portion, and an opening/closing portion. The operation portion includes a normal input portion on a front surface thereof and a special input portion on a back surface or side surface thereof. The attachment portion supports the operation portion such that an angle of the operation portion can be changed between a tilted angle at which the operation portion is set in a tilted attitude and an erected angle at which the operation portion is set in an erected attitude. The opening/closing portion covers up the special input portion when the operation portion is set at the tilted angle and exposes the special input portion when the operation portion is set at the erected angle.

Abstract: In the image forming apparatus, a controller applies a collection voltage to a cleaning roller by a voltage application part in image formation process. After making a toner image formed on an outer circumferential surface of an image carrier and transferred to a transfer-objective member, the controller predicts a toner charging level of after-transfer remaining toner which results after the transfer of the toner image, and changes at least either one of absolute value or polarity of the collection voltage applied to the cleaning roller in response to the toner charging level.

Abstract: In the image forming apparatus, a controller makes a reference image formed on an outer circumferential surface of an image carrier and transferred to a belt. Then, uncollected toner of the reference image, which is part of after-transfer remaining toner of the reference image that has missed being collected so as to remain even after one-round rotation of the image carrier, is transferred to the belt. The controller measures a collectable toner quantity corresponding to an applied voltage of the cleaning roller on a basis of an uncollected toner quantity estimated based on a toner concentration of the uncollected toner, and executes such adjustment that the collectable toner quantity becomes equal to or larger than a maximum value of the after-transfer remaining toner quantity and moreover the applied voltage becomes equal to or lower than a maximum applicable voltage.
