Provided is a safety scanner that enables simplification of an operation of checking an operating state. The safety scanner includes a scan image generation section that generates a scan image that includes a plurality of sets of distance measurement information obtained by performing scanning with a detection light emitted by an emitter, the plurality of sets of distance measurement information being represented as a plurality of distance measurement positions on a scanning plane of the detection light, and a monitoring image display that displays the scan image on a screen.

An imaging device capable of detecting differences with low power consumption is provided. The imaging device includes a pixel including a photoelectric conversion element and a transistor; an analog processing circuit; and a digital processing circuit. The imaging device is operated in a first mode and a second mode. In the first mode, the analog processing circuit detects a difference between first imaging data taken by the pixel and second imaging data taken by the pixel and generates a trigger signal on the basis of the value of the difference. In the second mode, the digital processing circuit converts third imaging data taken by the pixel into digital data. Switching from the first mode to the second mode is performed on the basis of the trigger signal.

A method for distributing load in a network of processing nodes, wherein the network includes a requesting node, and a set of external processing nodes. The method includes sending an Internet Control Message Protocol (ICMP) message to each external processing node, classifying each external processing node as being either a responding or a non-responding node based on its response time, identifying a responding node that has the capability to fulfill a video processing request, determining first and second sets of excluded responding nodes, selecting the identified node for fulfilling the video processing request, when the identified node does not form a part of the first and second sets of excluded responding nodes, sending a transmission package from the requesting node to the selected identified node for processing, and receiving a binary response from the selected node.

Provided is an apparatus including: a detecting unit configured to detect a state change of sound or light emitted from an external security apparatus to external environment; and a controlling unit configured to, in response to the detecting unit detecting the state change, cause a surveillance camera to capture images or apply a tag on image data being captured by the surveillance camera.

A method for automatically determining exposure settings for an image acquisition system comprises maintaining a plurality of look-up tables, each look-up table being associated with a corresponding light condition and storing image exposure settings associated with corresponding distance values between a subject and the image acquisition system. An image of a subject is acquired from a camera module; and a light condition occurring during the acquisition is determined based on the acquired image. A distance between the subject and the camera module during the acquisition is calculated. The method then determines whether a correction of the image exposure settings for the camera module is required based on the calculated distance and the determined light condition; and responsive to correction being required: selects image exposure settings corresponding to the calculated distance from the look-up table corresponding to the determined light condition; and acquires a new image using the selected image exposure settings.

A method for distributing load in a network of processing nodes, wherein the network includes a requesting node, and a set of external processing nodes. The method includes sending an Internet Control Message Protocol (ICMP) message to each external processing node, classifying each external processing node as being either a responding or a non-responding node based on its response time, identifying a responding node that has the capability to fulfill a video processing request, determining first and second sets of excluded responding nodes, selecting the identified node for fulfilling the video processing request, when the identified node does not form a part of the first and second sets of excluded responding nodes, sending a transmission package from the requesting node to the selected identified node for processing, and receiving a binary response from the selected node.

A smart motion detection device with a determining method includes a memory, a processor, and a sensor array coupled to the memory and the processor. An image captured by the sensor array is processed by the processor. The sensor array is adapted to pre-store the image into the memory when the processor is operated in the sleep mode, and the pre-stored image is transmitted to the processor when the processor is operated in the wakeup mode. The sensor array includes a comparator adapted to generate an alarm signal for switching the processor from the sleep mode to the wakeup mode in accordance with a comparison result of the pre-stored image. The determining method includes the processor analyzing images captured by the sensor array when the sensor array is activated to capture the images, and the processor analyzing images pre-stored inside the memory when the sensor array is not activated.

An imaging device with low power consumption is provided. It includes a pixel capable of outputting difference data between two different frames, a circuit determining the significance of the difference data, a circuit controlling power supply, an A/D converter, and the like; obtains image data and then obtains difference data; and shuts off power supply to the A/D converter and the like in the case where it is determined that there is no difference, and continues or restarts the power supply to the A/D converter and the like when it is determined that there is a difference. Determining the significance of the difference data can be performed row by row in a pixel array or at nearly the same time in all the pixels included in the pixel array.

Provided is an apparatus including: a detecting unit configured to detect a state change of sound or light emitted from an external security apparatus to external environment; and a controlling unit configured to, in response to the detecting unit detecting the state change, cause a surveillance camera to capture images or apply a tag on image data being captured by the surveillance camera.

A system for anomaly detection in a self-checkout environment, comprising a processing unit for receiving transaction data from a self-checkout terminal: characterising an activity based on a set of features extracted from the received transaction data; defining a plurality of active intervals for each characterised activity; determining a meta-feature vector for each defined active interval of the plurality of active intervals; comparing each meta feature vector with a predefined set of vectors; and determining an anomaly based on the comparison.
