Publication number: 20230347921Abstract: A vehicle display control system according to the present disclosure includes an obstacle sensor, an environmental factor sensor, a memory, and a hardware processor coupled to the memory. The obstacle sensor detects an obstacle around a vehicle. The environmental factor sensor detects an environmental factor that changes a detection range of the obstacle sensor with respect to the obstacle. The hardware processor is configured to: control a display device that converts a detection indication region falling within the detection range of the obstacle sensor with respect to the obstacle, into a detection indication image representing the detection indication region from a viewpoint of a driver of the vehicle, and superimposes and displays the detection indication image on a scene around the vehicle; correct the detection range in accordance with the environmental factor; and update the detection indication region in accordance with the detection range that has been corrected.Type: ApplicationFiled: February 6, 2023Publication date: November 2, 2023Inventor: Daisuke IWAHASHI

Publication number: 20100322317Abstract: To provide a simply-structured image decoding apparatus which appropriately executes parallel decoding processing. The image decoding apparatus includes: a stream segmentation unit (130) which generates plural segment streams by segmenting each of the pictures included in a bit stream into plural MB lines, and assigning each of the plural MB lines to a corresponding one of the plural segment streams to be generated; and plural decoding engines (120) which decode the respective plural segment streams in parallel. In the case where at least two consecutive MB lines in the bit stream have a dependency indicated by a predetermined code word, the stream segmentation unit (130) sets the code word to the segment streams so as to update the dependencies to new dependencies depending on the contexts of MB lines in the respective segment streams.Type: ApplicationFiled: October 27, 2009Publication date: December 23, 2010Inventors: Naoki Yoshimatsu, Daisuke Iwahashi, Takeshi Tanaka

Publication number: 20100254620Abstract: To provide a simply-structured image decoding apparatus which appropriately executes parallel decoding processing. The image decoding apparatus includes: a stream segmentation unit (130) which generates four segment streams by segmenting each of the pictures included in a bit stream into plural MB lines, and assigning each of the plural MB lines to a corresponding one of the four segment streams to be generated; and four decoding engines (120) which decode the respective four segment streams in parallel. When the stream segmentation unit (130) segments a slice in the picture into slice portions and assigns the respective slice portions to plural segment streams, the stream segmentation unit (130) reconstructs, as a new slice, the slice portion group including at least one slice portion to be assigned to a corresponding one of the segment streams so that the slice portion group is recognized as a slice by the associated one of the decoding engines (120).Type: ApplicationFiled: October 9, 2009Publication date: October 7, 2010Inventors: Daisuke Iwahashi, Naoki Yoshimatsu, Takeshi Tanaka
