Abstract:
A video encoding device includes a transformer for transforming an image block, an entropy encoder (103) for entropy encoding transformed data of the image block transformed by the transformer, a PCM encoder (1070) for PCM encoding the image block, and a multiplexed data selector (109) for selecting output data of any one of the entropy encoder (103) and the PCM encoder (1070) for each image block. The PCM encoder (1070) embeds, at the beginning of PCM data, a subsequent_pcm_flag syntax indicating whether an image block of PCM data follows or not.
Abstract:
A video encoding device includes a down-sampler with sampling position shifter 107 configured to down-sample a luminance signal, and a predictor 101 configured to linearly predict a color difference signal from a down-sampled luminance signal. The down-sampler with sampling position shifter 107 shifts a sampling position of the down-sampled luminance signal in accordance with a scan to be processed. A video decoding device includes a down-sampler with sampling position shifter 205 configured to down-sample a luminance signal, and a predictor 203 configured to linearly predict a color difference signal from a down-sampled luminance signal. The down-sampler with sampling position shifter 205 shifts a sampling position in the down-sampled luminance signal in accordance with a scan to be processed.
Abstract:
The disclosure is detecting an authentication target who is moving in a predetermined direction in a video; inputting a first image in which an entire body of the target; calculating characteristic information from an image of the entire body in the first image, comparing the calculated characteristic information with characteristic information of the entire body stored in first memory that stores characteristic information of entire bodies of targets, and extracting candidate information of the targets from the first memory based on a first authentication result; inputting a second image in which an iris of the target; and comparing characteristic information of irises stored in second memory that stores the characteristic information of the irises of targets with characteristic information of an iris from the second image, calculating a verification score, executing second authentication on the target in the second image based on the verification score, and outputting an authentication result.

Abstract:
Iris image pick-up devices have the same field of view and are disposed at mutually different positions. An overall image pick-up device performs image pick-up over a wide field of view. A guiding device guides a subject. An illumination device illuminates the subject with light. The controller controls, using an image from the overall image pick-up device, at least one of reading out an image from the iris image pick-up devices, presenting at least of an image and a sound through the guiding device, or providing illumination with light from the illumination device.
