Abstract

The concept of software‐based camera control and stabilisation and test results for two degree‐of‐freedom onboard cameras are presented in this paper. Contrary to the conventional gimballed observation cameras, the presented solution makes lightweight gimbal's construction possible. The unmanned aircraft state measurements and information of the target position are used in the computation of the desired angles of the camera rotation axes. The method has been tested using simulation technique. The results obtained in this paper show the need for fast enough camera actuation to stabilise image when aircraft attitude is disturbed by turbulence and attitude changes as a manoeuvre effect. The quantitative relationship between the parameters of camera actuators and achievable pointing accuracy are shown for exemplary flight condition simulation test.

Abstract

Looks at the use of robotic cameras in television news studios and the problems of navigating them accurately around their environment. Explains how the robots recognize coded targets around the studio which they compare with a preprogrammed map. Discusses the choice between laser scanners and line scan tv cameras to scan the targets and why the line scan camera was chosen; because it exhibited a number of advantages including a lower cost than the laser. Concludes that camera robot development is still at an early stage and is very mush responsive to user requirements. It remains to be seen whether they can move from the news and presentation studio environment into areas such as drama and light entertainment.

Abstract

Purpose

In addition to pioneering, empirical work on entry order increasingly addresses fast followers and laggards and the potential advantages they are able to capture. There is also a growing consensus in the academia, that current measures of firm performance used in the entry order literature to study these advantages are inadequate. This study analyzes the relationship between entry order and customer evaluations, which, depicting the performance of the firm's products in the market, are used as a proxy for firm performance.

Design/methodology/approach

The study is set in the digital camera industry, analyzing entries into each new technology level, in terms of the sensor resolution of compact and bridge cameras. The complete dataset consisted of 1,816 digital camera models introduced between January 1996 and December 2017. The data are analyzed using hierarchical multiple linear regression.

Findings

The study finds evidence of early-mover advantage for the compact product category. In the compact camera consumer market, both first-movers and fast followers outperform late movers. Furthermore, the difference in performance in comparison to laggards is greater for first-movers than for fast followers. However, in the bridge category which consists of a more heterogeneous set of products, no significant entry-order effects are detected.

Originality/value

The results clearly indicate that there exists an early mover advantage. Furthermore, the results are not consistent across different product categories within an industry; hence, caution needs to be exercised when analyzing industry dynamics and entry order effects. Finally, our novel conceptualization of firm performance measured as online customer evaluation add new opportunities to investigate firm success

Abstract

We examine how the organizational identity of established firms affects their strategic outcomes during the emergence phase of a new market. Drawing on cognitive theories of analogical learning, we build theory about how the established identities of producers influence the fluency with which consumers make sense of novel products, and hence affect valuations. We illustrate this theory through an empirical study of consumer evaluations of de alio entrants during the emergence of the digital camera industry.

Abstract

This chapter demonstrates that while in most late modern societies there is a neoliberal hegemony to expand police Closed-Circuit Television (CCTV) surveillance for crime control and antiterrorism, in Greece there is serious controversy and resistance against the post-Olympic use of more than 1,200 Olympic CCTV cameras. Drawing on the interesting politics of CCTV expansion and resistance, the chapter traces the reasons why, in the Greek context, this very expensive Olympic surveillance “dowry” has been opposed, even for traffic control. It critically attributes Greek citizens’ fear and mistrust primarily to their past police-state experience of authoritarian, thought-control surveillance.

Abstract

Purpose

The chapter aims to highlight developments in photography over the last two centuries, with an emphasis on the switch from analog to digital, and the emergence of Web 2.0 technologies, online photo management sites, and camera phones.

Design/methodology/approach

The chapter is a culmination of some of the key literature and research papers on photography, Web 2.0, Flickr, camera phones, and tagging, and is based on the author’s opinion and interpretation.

Findings

The chapter reports on how the switch from analog to digital has changed the methods for capturing, organizing, and sharing photographs. In addition, the emergence of Web 2.0 technologies and camera phones have begun to fundamentally change the way that people think about images and the kinds of things that people take photographs of.

Originality/value

The originality of the chapter lies in its predictions about the future direction of photography. The chapter will be of value to those interested in photography, and also to those responsible for the future development of photographic technology.

Abstract

This chapter is about the politics of surveillance and more specifically about the politics of siting public closed circuit television (CCTV) systems within urban neighborhoods. Through an exploration of political contests waged around attempts by local police to install public surveillance systems in the City of Vancouver's Downtown Eastside and Granville Mall districts, we argue that the success of public surveillance proposals is hardly inevitable. Instead, a combination of local factors play vital roles in variously supporting or constraining such attempts. Although this present chapter can be read as providing a useful counterpoint to the dominance of accounts about such developments in Great Britain, where public CCTV is a routine fact of daily urban life, we conclude on a cautionary note: with the current proliferation of public and private forms of surveillance throughout urban spaces, surveillance analysts risk missing the forest for the trees if we only concentrate on the fate of one surveillance tool or tactic.
