Comparison of Conventional and New methods of Measurement and Evaluation of Luminance
Svoboda, Miloslav ; Novák,, Tomáš (referee) ; Baxant, Petr (advisor)
Because luminance is the only value to which our sight responds, its measurement becomes important in terms of ensuring the proper function of vision. Nowadays luminance measuring can be made by conventional methods, such as direct using of luminance meter. However an entirely new method of measuring luminance levels is coming. This method is based on using luminance analyzers which work using a digital photography for the analysis of luminance. This thesis deals with these issues and is divided into several chapters, which form the two main parts of the thesis, the theoretical and the practical one. The theoretical part of the thesis deals with the basics of lighting technology, as well as the principles of measuring the luminance using conventional methods. New methods of measurement, i.e. using luminance analyzers, are discussed in two chapters which analyse both the principle and characteristics of analyzers available today. In the practical part is a comparative measurement carried out – in the laboratory and in terrain – using both methods.

Design of digital camera
Miklica, Martin ; Chorý, Tomáš (referee) ; Zvonek, Miroslav (advisor)
This work deals with the history, present and future of photography. The main objective however is to design a stylish compact digital camera with regard to the requirements of modern life, such as the expansion of internet social networks and the associated use of the camera as a visual scrapbook. Emphasis was placed on a new shape solution, simple operation and good ergonomics of holding.

Videosequention and their usage by physics education at basic school
MATĚJŮ, Petr
The Thesis "Videosequences and their use in teaching physics at the elementary school" provides a basic understanding of the issue of the use of audiovisual technology in an environment at the elementary school, focusing on the integration of video in teaching physics at the second stage. It describes the possibilities of video sources on the Internet and instructions for their preparation and to their own creation. The Thesis is also based on practical experiences that means the inclusion of specific movies in two selected topics in teaching physics.

Consumer preferences' based testing of consumer products
VALDMANOVÁ, Markéta
I used questionnaire investigation to reach the goal of my thesis. I wanted to ascertain the behaviour of users in the market when using the relevant product and to establish the importance of the attributes of digital camera for the user on the base of the research. Further my task was to set the weights of the individual attributes for multi-criteria decision-making. To compare the offered products with the help of the selected technique of multi-criteria decision-making and to suggest suitable products for the users on the base of the weights found out. The ascertained data and results will be further utilizable for consumer organizations, specifically for the Spotřebitelský institut SOS, o.p.s. (SOS Consumer institute, quasi-public company). I came to the following results after having evaluated my research. Most respondents own digital cameras, most frequently brand PANASONIC, CANON and OLYMPUS. The highest percentage of respondents use their cameras to record the personally significant moments, identically most frequently several times a week or several times a month. The main reason to choose a new camera is its function and price and the users are most frequently ready to spend between 3 001,- and 9 000,- CZK. Respondents prefer black and silver digital camera. As I supposed that there would be certain differences among the parameter preferences between genders and experiences of the users, I divided the respondents into individual segments in which I performed my further research. If I should assess the parameters most preferred by the respondents, there are certain differences between genders and experiences of the users. It is possible to say generally, on the base of the ascertained highest values of weights, that all user segments prefer the following parameters: noise (sensitivity), camera speed, battery durability, megapixel resolution and optic zoom. The clearly unimportant parameter is the possibility of printing directly from the camera that is on the last place of importance in all segments. I compared 25 digital cameras on the base of multi-criteria decision-making and the ascertained weights. I can recommend more or less the following 7 suitable products to the individual segments: Canon PowerShot SX1 IS, Panasonic Lumix DMC-FX500, Canon EOS 40D, Canon Ixus 870 IS, Casio EX-V7, Canon EOS 50D, Nikon D300.

Design of presentations as taeching materials for educational area "Člověk a svět práce"
KAHOVCOVÁ, Eva
This diploma thesis is dealing with the presentation of technical topic The usage of digital technologies from the educational program The human being and the work-world a with the didactical elaboration of this topic, specific to the theoretical section of Peripheral equipment of the PC and Digital camera. In the theoretical part of this thesis is written the characteristics of the educational program The human being and work-world and didactical technique needed to this topic. Next part is about how to use the PC at schools, and how to include the presentations to the education in light of the concept called Users conception of technical subjects{\crq} education. In the practical part of this thesis I try to suggest the detailed topics of Peripheral equipment of the PC and Digital camera education. The presentations were created to all theoretical knowledge and next step was the each topic methodology elaboration. The methodology was created to be able to suggest various kind of pupils{\crq} work and various educational tools. The thesis also contains the practical attestation of this suggest at basic school. This thesis provides the instruction, how to educate the topic The digital technologies usage especially for the technical education students.

Digitální fotografie a algoritmy pro rozeznávání obrazové informace
Čížek, Jakub ; Horný, Stanislav (advisor) ; Bébr, Richard (referee)
Tato práce se zabývá vznikem digitální fotografie. Kromě základního popisu a rozdělení digitálních fotoaparátů a jejich charakteristických součástí, je zde kladen důraz na vysvětlení vzniku barevného obrazu v digitálním přístroji. Podrobněji se tato práce zabývá především algoritmy pro rekonstrukci barevné informace ze surových dat (RAW) snímače. V poslední části je též provedeno srovnání různých interpolací barevného obrazu v praxi a diskuze vhodnosti jednotlivých postupů.
