摘要:
The present invention provides a human detection device which detects a human contained in a moving picture, and includes the following: a spatiotemporal volume generation unit which generates a three-dimensional spatiotemporal image in which frame images that make up the moving picture in which a human has been filmed are arranged along a temporal axis; a spatiotemporal fragment extraction unit which extracts a real image spatiotemporal fragment, which is an image appearing in a cut plane or cut fragment when the three-dimensional spatiotemporal image is cut, from the generated three-dimensional spatiotemporal image; a human body region movement model spatiotemporal fragment output unit which generates and outputs, based on a human movement model which defines a characteristic of the movement of a human, a human body region movement spatiotemporal fragment, which is a spatiotemporal fragment obtained from a movement by the human movement model; a spatiotemporal fragment verification unit which verifies between a real image spatiotemporal fragment and a human body region movement model spatiotemporal fragment; and an attribute output unit which outputs a human attribute which includes the presence/absence of a human in the moving picture, based on that verification result.

A monitoring device includes: a moving object image generation unit which receives, on a frame-by-frame basis, an overall image captured by a camera and performs inter-frame differential processing on the overall image or background differential processing between the overall image and a background image that is previously prepared; a density calculation unit which transforms the differential processed image (a moving object image) into one-dimensional information and calculates a density indicating a degree of density of moving objects or of a crowd through frequency analysis; a model generation unit which calculates a reference density (a model value) of the moving objects or of the crowd based on the density of a predetermined date and time; and a situation determination unit which compares between the density at the current time and the reference density, determines whether or not the density at the current time is different from the reference density, generates a determination result, and provides the result to a notification unit.

摘要:
An image processing device and an image processing method capable of generating a moving image having a high resolution and a high frame rate are provided by suppressing the reduction in the amount of incident light on each camera. The imaging and processing device includes a separation section for separating visible light into at least a first color component and a second color component; a first imaging section for taking a moving image of the first color component, wherein the first imaging section takes images of the moving image with a first spatial resolution and a first temporal resolution by exposure for a first charge accumulation time period; a second imaging section for taking a moving image of the second color component, wherein the second imaging section takes images of the moving image with a second spatial resolution higher than the first spatial resolution and a second temporal resolution lower than the first temporal resolution by exposure for a second charge accumulation time period longer than the first charge accumulation time period; a control section for controlling imaging conditions of the first and the second imaging sections; and a processing section for generating a moving image of the second component having the temporal and spatial resolutions thereof increased, based on information on the moving image of each of the first color component and the second color component.
