摘要： A coded data generation method of generating coded data of a plurality of bit rates in which an image is encoded includes the steps of: acquiring an evaluated value at distribution destinations of the generated coded data when the coded data is reproduced; and changing the bit rate of the coded data to be generated based on a distribution of the acquired evaluated value in all channels.

摘要： A coding method encodes an image by dividing the image into blocks, and comprises: dividing a coding target image into a plurality of coding unit blocks; determining whether or not to encode by dividing the coding unit block into a plurality of sub-coding unit blocks, on a basis of an edge direction and an edge strength of an edge obtained for each pixel in the coding unit block; and encoding, in a case of determining to divide the coding unit block into a plurality of sub-coding unit blocks in the determining step, a first sub-coding unit block by referencing a second sub-coding unit block inside the same coding unit block as the first sub-coding unit block.

摘要： In a decoding apparatus configured to perform decoding processing in parallel using N arithmetic decoding units and M image decoding units on a plurality of slices, each slice being composed of at least one encoding block line, the N arithmetic decoding units start arithmetic decoding processing in sequence at time intervals corresponding to slice sizes on a stream that satisfies a condition that a difference between a total number of encoding block lines included in any N consecutive slices and a total number of encoding block lines included in N consecutive slices different from the any N consecutive slices is 1 or less, and a condition that a code amount of each slice is less than a predetermined upper limit code amount.

摘要： An object detecting device includes: an overall processing unit configured to perform object detection processing on an input image; an allocation processing unit configured to determine a segmented image for each frame which is subject to object detection among the plurality of segmented images in advance in a cycle of N frames, and reserve the determined segmented image; a selection processing unit configured to select and output, for each frame, some of the segmented images that are subject to object detection among the plurality of segmented images based on a reservation result from the allocation processing unit; a division processing unit configured to perform object detection processing on each of the segmented images output from the selection processing unit; and a synthesizing processing unit configured to synthesize an object detection result from the overall processing unit and an object detection result from the division processing unit.
