Abstract: An information processing device includes a processor; and a memory storing a program which causes the information processing device to: select a virtual object present at a line-of-sight position of a user as a control object; determine whether or not the user performed a predetermined operation for visually recognizing a rear of the control object; and execute control that the control object is moved and displayed such that the rear of the control object can be visually recognized, wherein a direction in which the control object is to be moved is determined based on at least either one of a moving direction and a rotating direction of a head part of the user, or a distance for which the control object is to be moved is determined based on at least either one of a movement amount and a rotation amount of the head part of the user.

Abstract: A medical image processing apparatus employs a trained model generated by performing machine learning using training data that includes first input data including a first image regarding a liver, and portal vein branch labeling data in which a portal vein branch label is attached to a portal vein region in the liver in the first image for each portal vein branch corresponding to a hepatic segment. The medical image processing apparatus uses the trained model to assign the portal vein branch label to each image unit element of a second image region including at least a liver region of the second image included in a second input data which is the same type as the first input data, and divides the liver region included in the second input data into hepatic segments based on the portal vein branch label assigned to each image unit element of the second image region.

Abstract: A driving control apparatus is configured to control a driving unit that moves relative to each other a vibrator that is excited to vibrate by applying a first driving signal and a second driving signal that have a phase difference with each other, and a contact member that contacts the vibrator. The driving control apparatus includes a first control unit configured to control the phase difference, and a second control unit configured to control a voltage amplitude of each of the first driving signal and the second driving signal. The second control unit controls the voltage amplitude so that a change rate of the voltage amplitude increases as an absolute value of the phase difference decreases.

Abstract: An image stabilization apparatus which is capable of properly correcting for image blurring while at the same time obtaining correct focus evaluation values. Based on a detected shake, a vibration isolation lens is moved in a direction different from a direction of an optical axis of a shooting optical system. While a focus lens is being moved in the direction of the optical axis, focus evaluation values are obtained based on an image pickup signal obtained by taking an image of a subject. A method to control the focus lens is determined according to whether or not the focus lens is being moved, and with the determined method, movement of the focus lens in the direction of the optical axis is controlled based on an amount by which the vibration isolation lens has moved.

Abstract: A lens control device which is capable of controlling lens positions such that an in-focus state of an object image can be maintained even when a variable power lens is positioned outside a normal zoom range from a wide-angle end to a telephoto end. A flash memory stores a positional relationship between the variable power lens and a focus lens, on an object distance-by-object distance basis. A system controller controls the movement of the focus lens by calculating the in-focus position of the focus lens with respect to the position of the variable power lens based on the positional relationship stored in the flash memory when the variable power lens is moved to a position outside the normal zoom range defined in the positional relationship stored in the flash memory.

Abstract: In a write once type optical disc, when ejecting the disc and turning power OFF, it is necessary to update record management data on the disc so that the record management data on the disc coincide with the record management data on the memory. Here, the update of the record management data on the disc requires a certain time. The present invention provides a user-friendly recording/reproduction apparatus including a unit for judging whether the disc record management information can be updated according to the ratio of the recorded capacity with respect to the recording-enabled capacity. Upon completion of the user data recording, the disc record management information is recorded so that the record management data is not updated when power is turned OFF or the disc is ejected, thereby reducing the time required for the power turning OFF and the disc ejection.
