摘要： An image capture detection system including a short range radio transmitter (13) and a short range radio receiver and decoder (12) installed in or on an image capture device (10). The system further comprises a remote detection unit (14) also comprising a short range radio transmitter (18) and a short range radio receiver and decoder (16). In use, the remote detection unit (14) transmits intermittent query signals (22) which are received by the receiver (12) in the image capture device (10) when the remote detection unit (14) is within a predetermined distance or range thereof. In response to receipt of the query signals (22), the transmitter (13) in the image capture device (10) is arranged to transmit an indicator signal (24) which is received by the remote detection unit (14). The remote detection unit (14) is arranged to generate a warning signal in response to receipt of the indicator signal ((24).

摘要： A method and apparatus for controlling the operation of a system having a plurality of video cameras. The cameras are linked to a control unit which has a motion detection apparatus for monitoring the images received from the cameras and detecting motion therein. The cameras are adapted to operate in at least two modes: a low resolution mode and a high resolution mode. Under normal circumstances, cameras will be operating in low resolution mode to minimize use of system resources. If activity is detected within the field of view of one of the cameras, that camera is switched to high resolution, the other cameras remaining in the low resolution mode.

摘要： A digital camera derives an infrared and visible signals from IR and visible sensors. The sensor fields of view overlap or share a common field of view. An analyzer of the IR signal provides the location of and information from an active or passive IR target. The analyzer responds to the location and information signals for visible image composition control (pan/tilt/zoom/timing) and selection of visible image pictures for storage to provide ancillary information, such as personal details of a target wearer. The visible and infrared image signals are combined to correct for sensitivity of the visible and/or IR sensors to IR and visible wavelengths, respectively.

摘要： This invention relates to the reconstruction of a full colour image from image mosaic data in particular where the image mosaic data is unequally weighted between different colours. The image mosaic is composed of a plurality of image pixels. Each image pixel has one of at least three colour values and has a luminance value representing the intensity of the colour value for that pixel in the image mosaic. The pixels of each colour value are interleaved across the image mosaic with pixels of different colour values to form the image mosaic. For each colour value, both a low spatial frequency monochrome image and a high spatial frequency luminance image are generated, the high spatial frequency luminance image extending only across pixels locations of the image mosaic for that colour value. Each of the high spatial frequency luminance images is then combined with a corresponding low spatial frequency monochrome image to form the full colour image.

摘要： An image capture system comprises a portable computer having a software-implemented subsystem and a connection to a sensor responsive still image digital camera including a control module and a FIFO buffer for storing more than one but less than two data image frames. When the image subsystem reaches a point during reading of a frame from the buffer where it is “safe” for the next image data frame captured by the image sensor to be stored in the buffer, the subsystem issues a “continue” signal, causing the next image data frame to be stored in the buffer. The “continue” signal is only issued if the buffer has sufficient capacity for the next frame to be completely stored. The “continue” signal minimizes frame loss, optimizes memory requirement, and sensibly drops frames when the host computer cannot handle image data at the same rate they are generated.

摘要： This invention relates to the reconstruction of a color plane in image mosaic data with correction for color aliasing artefacts, in particular where the image mosaic data is unequally weighted between different colors. The image mosaic is composed of a plurality of interleaved image pixels of at least three color values, each of which has a luminance value. Each row and column of the mosaic contains image pixels of at least two colors. An edge strength metric is assessed at locations in the image mosaic using at least two luminance values of the same color value to determine the strength of luminance changes and hence of detected edges at said locations. A low spatial frequency image is generated for each color value in which changes in luminance values are smoothed. The smoothing for each color value is in accordance with said edge strength metric so that smoothing at the locations of detected edges is inhibited. A high spatial frequency image is generated from the image mosaic, which combined with the smoothed low spatial frequency images for each color value results in a de-mosaiced color image with reduced or eliminated color aliasing along edges.
摘要翻译：本发明涉及对具有彩色混叠伪影的校正的图像镶嵌数据中的彩色平面的重建，特别是其中图像镶嵌数据在不同颜色之间不均匀加权的情况。图像马赛克由至少三个颜色值的多个交错图像像素组成，每个具有亮度值。马赛克的每行和列都包含至少两种颜色的图像像素。使用相同颜色值的至少两个亮度值来评估图像镶嵌中的位置处的边缘强度度量，以确定亮度变化的强度，并因此确定所述位置处检测到的边缘的强度。对于其中平滑了亮度值的变化的每个颜色值，生成低空间频率图像。对于每个颜色值的平滑与所述边缘强度度量相一致，使得在检测到的边缘的位置处的平滑被抑制。从图像马赛克产生高空间频率图像，其与针对每个颜色值的平滑的低空间频率图像组合导致沿边缘具有减少或消除的颜色混叠的去镶嵌彩色图像。
