In a case where it is identified based on fisheye information that an input image is a fisheye image, a block position computing section computes the position of a processing target block relative to a fisheye center, and outputs, to a table selecting section, positional information representing the computed position. In a case where it is identified based on fisheye information that an input image is a fisheye image, the table selecting section selects, on the basis of positional information, an intra-prediction mode table according to the position of a processing target block from a plurality of intra-prediction mode tables, and outputs the selected intra-prediction mode table to a prediction image generating section. By using the intra-prediction mode table supplied from the table selecting section and the reference image data read out from a frame memory via a selecting section, the prediction image generating section performs direction prediction and generates prediction image data for prediction modes represented in the intra-prediction mode table. An encoding or decoding process on an image on which distortions are generated can be performed efficiently.

An amount-of-remaining-toner detecting device includes: a toner housing portion in which a toner bottle is housed, the toner bottle having a bottle body that is cylindrical and in which toner is housed, and a cap that is attached to one end of the bottle body in an axial direction of the bottle body and from which the toner housed in the bottle body is discharged; and circuitry configured to detect an amount of remaining toner in the toner bottle housed in the toner housing portion. The toner housing portion includes a first pair of electrodes facing each other with the bottle body interposed between the first pair of electrodes, and a second pair of electrodes facing each other with the bottle body interposed between the second pair of electrodes, at respective positions closer to the cap than the first pair of electrodes are. The circuitry detects the amount of remaining toner in the bottle body, based on at least one of a capacitance value between the first pair of electrodes or a capacitance value between the second pair of electrodes.

Amount-of-remaining-toner detecting device, image forming apparatus, method for detecting amount of remaining toner, and non-transitory recording medium

A remaining toner amount detection device includes four electrodes and a controller. Each electrode has an arc shape along an outer circumferential surface of a toner bottle, and the four electrodes are spaced a certain distance apart in a circumferential direction so as to surround the toner bottle. The controller detects a remaining toner amount inside the toner bottle by using the four electrodes. The controller determines whether at least one of a first electrostatic capacity value between one pair of adjacent electrodes and a second electrostatic capacity value between the other pair of adjacent electrodes falls within a threshold range. In response to determination that at least one of the electrostatic capacity values falls within the threshold range, the controller detects a remaining toner amount inside the toner bottle based on an electrostatic capacity value, and outputs the detected remaining toner amount.

A motion vector correction unit including a correction method determination unitand an inter-prediction unitperforms scaling processing on a motion vector of, for example, a peripheral block of a current predictive block in a fisheye image shot using a fisheye lens, on the basis of fisheye information, for example, a projection method of the fisheye lens and a radius of the fisheye image. The scaling processing performs scaling by transforming the motion vector of the peripheral block to a motion vector of an image having no fisheye distortion, and transforms the motion vector after the scaling to the motion vector in the fisheye image. By reducing a difference between a motion vector of the current predictive block and a predictive motion vector by performing the scaling processing, encoding efficiency of the fisheye image can be improved.
