TL;DR: A user-actuated modular photography system for use in a photobooth or like enclosure to provide user self-photography with realistic user-selective user image previewing includes a camera module having a housing including a photographic camera having a lens oriented for viewing the user when within camera lens view of the photographic camera.
Abstract: A user-actuated modular photography system for use in a photobooth or like enclosure to provide user self-photography with realistic user-selective user image previewing includes a camera module having a housing including a photographic camera having a lens oriented for viewing the user when within camera lens view of the photographic camera, a video camera and a gimballed camera mount assembly interconnecting the video camera with the photographic camera for video imaging by the video camera of the photographic camera lens view of the user, the video camera providing a user video image signal. There is also a gimbal drive mechanism for providing driven gimballed movement of the camera mount assembly for selective aiming of the camera lens axis within at least one aiming plane and for selective rotation of the camera lens view within an image resolution plane between vertical and horizontal orientations. Also included is at least one modular display device for colocation with the camera module within a photobooth or like enclosure. The modular display device includes video image display mechanism for receiving the user video image signals for vertical and horizontal modes of display of the user video image for user image previewing prior to user image exposure by the photographic camera. Circuit means are included for causing the video display means to switch automatically between the first and second display modes in response to said lens view rotation. Also, a user control device provides for user selective remote control of the aiming movement of the camera assembly, selection of the image rotation between the vertical and horizontal orientations, and for user selective remote actuation of the photographic camera for thereby capturing user photographic images in accordance with user previewed realistic display thereof by the video display mechanism.

TL;DR: The design, kinematic and perception models, and mechatronical integration of a novel multi-focal four camera vision system targeting at real-world wide distance range applications is presented.
Abstract: A novel multi-focal four camera vision system is presented. The dynamic performance reaches velocities and accelerations exceeding far beyond human capabilities. Extreme wide-angle aperture angles to narrow foveated are provided simultaneously and are independently controllable. The vision system is designed in the context of the new development of the successor model of the humanoid robot Johnnie targeting at real-world wide distance range applications. This paper presents the design, kinematic and perception models, and mechatronical integration. The dynamic performance is evaluated in experiments. A novel multi-camera view direction stabilization strategy is presented and experimentally validated

TL;DR: In this article, a camera unit detects a change in circumstances surrounding the camera unit and, in response to detection of the change, it captures an image and extracts a partial image corresponding to an area in which the change occurred.
Abstract: PROBLEM TO BE SOLVED: To provide an image processing apparatus or the like capable of exactly grasping a change in circumstances of a captured image, even in a system where the capability of a display device is not sufficient, or the capability of a network is not sufficient. SOLUTION: A camera unit detects a change in circumstances surrounding the camera unit. In response to detection of the change, the camera unit captures (S11) an image. From the captured image, the camera unit extracts (S12) a partial image corresponding to an area in which the change in circumstances occurred. The camera unit transmits (S13) the extracted partial image to a server unit. COPYRIGHT: (C)2005,JPO&NCIPI

TL;DR: In this paper, a computer-implemented method navigates a virtual camera in a three-dimensional environment on a mobile device having a touch screen, indicating that two objects have touched a view of the mobile device and the two objects had moved relative to each other.
Abstract: This invention relates to user interface gestures for moving a virtual camera on a mobile device. In an embodiment, a computer-implemented method navigates a virtual camera in a three dimensional environment on a mobile device having a touch screen. A user input is received indicating that two objects have touched a view of the mobile device and the two objects have moved relative to each other. A speed of the objects is determined based on the user input. A speed of the virtual camera is determined based on the speed of the objects. The virtual camera is moved relative to the three dimensional environment according to the speed of the virtual camera.

TL;DR: Experimental results demonstrate that the hybrid method is superior to Gabor and wavelet methods on detection accuracy and actual operations in a textile factory verify the effectiveness of the inspection system.
Abstract: In this study, an embedded machine vision system using Gabor filters and Pulse Coupled Neural Network (PCNN) is developed to identify defects of warp-knitted fabrics automatically. The system consists of smart cameras and a Human Machine Interface (HMI) controller. A hybrid detection algorithm combing Gabor filters and PCNN is running on the SOC processor of the smart camera. First, Gabor filters are employed to enhance the contrast of images captured by a CMOS sensor. Second, defect areas are segmented by PCNN with adaptive parameter setting. Third, smart cameras will notice the controller to stop the warp-knitting machine once defects are found out. Experimental results demonstrate that the hybrid method is superior to Gabor and wavelet methods on detection accuracy. Actual operations in a textile factory verify the effectiveness of the inspection system.
