Abstract:
An M-channel (M is an integer of at least two) synchronous rectification type step-down DC/DC converter is provided. A controller in the converter (i) calculates a load current on a basis of currents flowing through M inductors, (ii) dynamically changes the number K of driving phases (K is an integer of up to M) on the basis of the calculated load current, (iii) generates a pulse signal adjusted in duty ratio such that an output voltage of an output line coincides with a predetermined reference voltage, (iv) selects K drivers among M drivers, and distributes the pulse signal with a phase difference of (360/K) degrees to each of the selected K drivers, and (vi) monotonically increases an amplitude control signal indicating the amplitude of a gate driving voltage with respect to the calculated load current in a range determined in advance for each number K of driving phases.
Abstract:
To provide an electronic device capable of preventing an enclosure from falling down without providing a stand and also improving heat dissipation of the enclosure. An electronic device (1) according to the present invention has a substrate (3) where a data storage unit (5) incorporating a storage medium is mounted, and a columned enclosure (2) for storing the substrate (3) in a standing posture, with an axial direction thereof directed to the vertical direction. The enclosure (2) has a pair of lateral walls (22, 23) opposite to the substrate (3) in the Y1-Y2 direction. The pair of lateral walls (22, 23) have a curved shape curved so that middle portions in the Z1-Z2 direction depart from the substrate (3) more than the respective both ends in the Z1-Z2 direction.
Abstract:
When an acquisition unit acquires image data of a game being played on another information processing apparatus, a display processing unit displays, using the acquired image data, an image of game play. A participation processing unit allows a user to join the game being played on the other information processing apparatus, and a transmission unit transmits operation information from the user to the other information processing apparatus. When the acquisition unit acquires image data in which the transmitted operation information is reflected in the progress of the game in the other information processing apparatus, the display processing unit displays, using the image data, an image of game play in which the operation information is reflected.
Abstract:
Systems and methods for executing a game presented on a screen of a head mounted display include executing a game. The execution of the game renders interactive scenes of the game on the screen of the HMD. Images identifying a shift in gaze direction of the user wearing the HMD, are received. The gaze shift is detected during viewing of the interactive scenes presented on the HMD screen. Real-world images that are in line with the gaze direction of the user, are captured from a forward-facing camera of the HMD. A portion of the screen is transitioned from a non-transparent mode to a semi-transparent mode in response to the shift in the gaze direction such that at least part of the real world images are presented in the portion of the screen rendering the interactive scenes of the game. The transparent mode is discontinued after a period of time.
Abstract:
Graphics processing may include implementing a vertex shader and a pixel shader with the GPU. Vertex indices output from a vertex shader may be written to a cache. The vertex indices written to the cache may be accessed with the pixel shader and vertex parameter values associated with the vertex indices may be accessed from a memory unit with the pixel shader. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
Abstract:
A set of graphics primitive information for a virtual object may be processed with compute shader running on a graphics processing unit (GPU) to generate a modified set of primitive information. The modified set of primitive information may be passed to a vertex shader running on the GPU. The vertex shader may perform vertex shading on the modified set of primitive information. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

Abstract:
Methods, systems, and computer programs are presented for managing the display of images on a head mounted device (HMD). One method includes an operation for tracking the gaze of a user wearing the HMD, where the HMD is displaying a scene of a virtual world. In addition, the method includes an operation for detecting that the gaze of the user is fixed on a predetermined area for a predetermined amount of time. In response to the detecting, the method fades out a region of the display in the HMD, while maintaining the scene of the virtual world in an area of the display outside the region. Additionally, the method includes an operation for fading in a view of the real world in the region as if the HMD were transparent to the user while the user is looking through the region. The fading in of the view of the real world includes maintaining the scene of the virtual world outside the region.
Abstract:
A low dynamic range (LDR) image data storage stores LDR image sets each of which includes a plurality of LDR segmented images captured with a camera panned. Here each LDR image set is of a different exposure level, respectively. A high-dynamic-range (HDR) synthesizing unit combines and merges a plurality of LDR segmented images of different exposure levels so as to generate an HDR segmented image set including a plurality of HDR segmented images of different pan angles or tilt angles. A panoramic image synthesizing unit generates an HDR panoramic image by stitching together adjacent HDR segmented images.
Abstract:
In response to a selection of a program, a board image display control section sets program related information associated with the selected program in a displayable state. An execution start managing section starts the program in response to reception of a request to start the program, the program related information associated with the program being set in the displayable state. A stop and end managing section ends an already started program when a given condition is satisfied at a time of starting the program by the execution start managing section. A setting of program related information associated with the ended program is maintained in a displayable state even after the program is ended by the stop and end managing section.
