Patent number: 11689812Abstract: Disclosed is a camera system included in a vehicle. The camera system comprises: a camera provided to a vehicle so as to capture the surroundings of the vehicle; and a processor for identifying an object present near the vehicle on the basis of an image captured by the camera, wherein the camera comprises a wide-angle lens, and a plurality of optical sensors for capturing a region within the viewing angle of the wide-angle lens, the wide-angle lens being designed so that the number of optical sensors for capturing a region corresponding to a predetermined angle range, among a plurality of angle ranges formed by dividing the viewing angle into predetermined angles, differs from the number of optical sensors for capturing a region corresponding to a different angle range.Type: GrantFiled: October 30, 2019Date of Patent: June 27, 2023Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jeonghoon Seo, Sanggun Lee, Hyeongchan Seo, Taejung Yeo

Patent number: 9571851Abstract: The present disclosure relates to an inter prediction method and apparatus using adjacent pixels, and a video encoding method and apparatus using the same. The inter prediction method for a predictive encoding includes: determining a current motion vector by estimating a motion of a current block; generating a reference block indicated by the current motion vector; calculating a motion compensation coefficient or an average compensation coefficient by using pixels neighboring the current block and pixels neighboring reference block; generating a changed reference block reflecting the motion compensation coefficient or the average compensation coefficient in the reference block; and determining the changed reference block as a predicted block of the current block. The present disclosure reduces a difference between an actual block and a predicted block by more accurately predicting the block to be encoded, thereby improving the compression efficiency.Type: GrantFiled: September 24, 2010Date of Patent: February 14, 2017Assignee: SK TELECOM CO., LTD.Inventors: Sunyeon Kim, Jeongyeon Lim, Yunglyul Lee, Joohee Moon, Haekwang Kim, Byeungwoo Jeon, Jongki Han, Jeonghoon Seo, Daeyeon Kim, Sungwook Hong, Jaehoon Choi, Gyumin Lee

Patent number: 9154809Abstract: Disclosed is a high-resolution video encoding/decoding method and apparatus. The video encoding method includes: predicting a current block to generate a predicted block, subtracting the predicted block from the current block to generate a residual block, determining a transform and quantization type according to the block type of the current block; transforming and quantizing the residual block according to the determined transform and quantization type; and encoding the transformed and quantized residual block. According to the video encoding/decoding method and apparatus, not only the encoding efficiency can be improved because it enables an encoding using a high correlation between temporally/spatially adjacent pixels appearing in a video, but the compression efficiency can also be improved by reducing block distortion.Type: GrantFiled: September 3, 2010Date of Patent: October 6, 2015Assignee: SK TELECOM CO., LTD.Inventors: Sunyeon Kim, Jeongyeon Lim, Yunglyul Lee, Joohee Moon, Byeungwoo Jeon, Haekwang Kim, Jeonghoon Seo, Kioh Kim, Sungwook Hong
