Instruction Manual Go to for ENGLISH, FRANÇAIS, DEUTSCH, ITALIANO, ESPAÑOL and NEDERLANDS Translations
Fisheye Wide Angle Lens (SL975) Instruction Manual Go to www.sealife-cameras.com/manuals for ENGLISH, FRANÇAIS, DEUTSCH, ITALIANO, ESPAÑOL and NEDERLANDS translations. 1. What’s in the Box: Lens (SL97501) with Retaining Lanyard (SL95010) Neoprene Lens cover (SL97508) Lens Dock (SL97502) With mounting screw (SL97201) 2. Great Pictures Made Easy Without and …………………….with Fisheye Lens The secret to taking bright and colorful underwater pictures is to get close to the subject. The fisheye wide angle lens creates a super wide angle effect that allows you to get closer to the subject and still fit everything in the picture. In addition to increasing field of view, the fisheye lens will help you shoot better, steadier video by dampening movement. You will also be able to take super macro pictures with increased depth of field. 3. Attach Lens Dock Screw Lens Dock on to bottom of flash tray 4. Attach Retaining Lanyard To prevent dropping or losing the lens, attach the lens retaining lanyard to the camera as shown. When the lens is not being used, slide it in to Lens Dock to secure and protect lens. 5. Attach Lens to Camera Push lens onto lens port of any SeaLife “DC”-series underwater camera. Lens can be attached on land or underwater. When entering the water, make sure to remove air bubbles trapped under the lens - There should be water between the lens and the camera. Important: The camera’s focus setting must be set to “Macro Focus” or “Super Macro Focus” or the resulting picture/video will not be in focus. -

Optics – Panoramic Lens Applications Revisited
Panoramic Lens Applications Revisited Simon Thibault* M.Sc., Ph.D., Eng Director, Optics Division/Principal Optical Designer ImmerVision 2020 University, Montreal, Quebec, H3A 2A5 Canada ABSTRACT During the last few years, innovative optical design strategies to generate and control image mapping have been successful in producing high-resolution digital imagers and projectors. This new generation of panoramic lenses includes catadioptric panoramic lenses, panoramic annular lenses, visible/IR fisheye lenses, anamorphic wide-angle attachments, and visible/IR panomorph lenses. Given that a wide-angle lens images a large field of view on a limited number of pixels, a systematic pixel-to-angle mapping will help the efficient use of each pixel in the field of view. In this paper, we present several modern applications of these modern types of hemispheric lenses. Recently, surveillance and security applications have been proposed and published in Security and Defence symposium. However, modern hemispheric lens can be used in many other fields. A panoramic imaging sensor contributes most to the perception of the world. Panoramic lenses are now ready to be deployed in many optical solutions. Covered applications include, but are not limited to medical imaging (endoscope, rigiscope, fiberscope…), remote sensing (pipe inspection, crime scene investigation, archeology…), multimedia (hemispheric projector, panoramic image…). Modern panoramic technologies allow simple and efficient digital image processing and the use of standard image analysis features (motion estimation, segmentation, object tracking, pattern recognition) in the complete 360o hemispheric area. Keywords: medical imaging, image analysis, immersion, omnidirectional, panoramic, panomorph, multimedia, total situation awareness, remote sensing, wide-angle 1. INTRODUCTION Photography was invented by Daguerre in 1837, and at that time the main photographic objective was that the lens should cover a wide-angle field of view with a relatively high aperture1. -

Contact Information: Author(s): Sathwika Bavikadi E-mail: [email protected] Venkata Bharath Botta E-mail: [email protected] Supervisor: Irina Gertsovich University Examiner: Dr. Sven Johansson Department of Applied Signal Processing Internet : www.bth.se Blekinge Institute of Technology Phone : +46 455 38 50 00 SE–371 79 Karlskrona, Sweden Fax : +46 455 38 50 57 Abstract Images, unlike text, represent an effective and natural communica- tion media for humans, due to their immediacy and the easy way to understand the image content. Shape recognition and pattern recog- nition are one of the most important tasks in the image processing. Crime scene photographs should always be in focus and there should be always be a ruler be present, this will allow the investigators the ability to resize the image to accurately reconstruct the scene. There- fore, the camera must be on a grounded platform such as tripod. Due to the rotation of the camera around the camera center there exist the distortion in the image which must be minimized. -
Hardware and Software for Panoramic Photography
ROVANIEMI UNIVERSITY OF APPLIED SCIENCES SCHOOL OF TECHNOLOGY Degree Programme in Information Technology Thesis HARDWARE AND SOFTWARE FOR PANORAMIC PHOTOGRAPHY Julia Benzar 2012 Supervisor: Veikko Keränen Approved _______2012__________ The thesis can be borrowed. School of Technology Abstract of Thesis Degree Programme in Information Technology _____________________________________________________________ Author Julia Benzar Year 2012 Subject of thesis Hardware and Software for Panoramic Photography Number of pages 48 In this thesis, panoramic photography was chosen as the topic of study. The primary goal of the investigation was to understand the phenomenon of pa- noramic photography and the secondary goal was to establish guidelines for its workflow. The aim was to reveal what hardware and what software is re- quired for panoramic photographs. The methodology was to explore the existing material on the topics of hard- ware and software that is implemented for producing panoramic images. La- ter, the best available hardware and different software was chosen to take the images and to test the process of stitching the images together. The ex- periment material was the result of the practical work, such the overall pro- cess and experience, gained from the process, the practical usage of hard- ware and software, as well as the images taken for stitching panorama. The main research material was the final result of stitching panoramas. The main results of the practical project work were conclusion statements of what is the best hardware and software among the options tested. The re- sults of the work can also suggest a workflow for creating panoramic images using the described hardware and software. The choice of hardware and software was limited, so there is place for further experiments. -

Depth of Field in Photography
Instructor: N. David King Page 1 DEPTH OF FIELD IN PHOTOGRAPHY Handout for Photography Students N. David King, Instructor WWWHAT IS DDDEPTH OF FFFIELD ??? Photographers generally have to deal with one of two main optical issues for any given photograph: Motion (relative to the film plane) and Depth of Field. This handout is about Depth of Field. But what is it? Depth of Field is a major compositional tool used by photographers to direct attention to specific areas of a print or, at the other extreme, to allow the viewer’s eye to travel in focus over the entire print’s surface, as it appears to do in reality. Here are two example images. Depth of Field Examples Shallow Depth of Field Deep Depth of Field using wide aperture using small aperture and close focal distance and greater focal distance Depth of Field in PhotogPhotography:raphy: Student Handout © N.

The second image (on the right) was shot with a smaller aperture and is focused on a yellow flower near the rear of that group of flowers. Though it looks as if we are really increasing the area that is in focus from the first image to the second, that apparent increase is actually an optical illusion. In the second image there is still only one plane where the lens is critically focused. -

The Trade-Off Between Image Resolution and Field of View: the Influence of Lens Selection
The Trade-off between Image Resolution and Field of View: the Influence of Lens Selection “I want a lens that can cover the whole parking lot and I want to be able to read a license plate.” Sound familiar? As a manufacturer of wide angle lenses, Theia Technologies is frequently asked if we have a product that allows the user to do both of these things simultaneously. And the answer is ‘it depends’. It depends on several variables - the resolution you start with from the camera, how far away the subject is from the lens, and the field of view of the lens. But keeping the first two variables constant, the impact of the lens field of view becomes clear. One of the important factors to consider when designing video surveillance installations is the trade-off between lens field of view and image resolution. Image Resolution versus Field of View One important, but often neglected consideration in video surveillance systems design is the trade-off between image resolution and field of view. With any given combination of camera and lens the native resolution from the camera is spread over the entire field of view of the lens, determining pixel density and image resolution. The wider the resolution is spread, the lower the pixel density, the lower the image resolution or image detail. The images below, taken with the same camera from the same distance away, illustrate this trade-off. The widest field of view allows you to cover the widest area but does not allow you to see high detail, while the narrowest field of view permits capture of high detail at the expense of wide area coverage.
