Efficient Color Space Conversion using Custom Instruction in a RISC Processor
2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007A new architecture for color space conversion in RGB to YCbCr domain has been proposed. The architecture exploits the similarity in bit-planes of a natural image to bring the algorithmic efficiency of distributed arithmetic (DA) approach close to that of a full multiplier design.

Organic Electronics, 2012
Abstract We report our study on white organic light-emitting diodes (WOLEDs) implemented in a down-conversion scheme based on an ITO-free, cavity-enhanced blue phosphorescent OLED and a micro-structured color conversion layer (CCL) containing red and green phosphors.

Efficient RGB to YCbCr Color Space Conversion for Embedded Application
Applied Mechanics and Materials, 2014Modern embedded portable devices usually have to deal with large amounts of video data. Due to massive floating-point multiplications, the color space conversion is inefficient on the embedded processor. Considering the characteristics of RGB to YCbCr color space conversion, this paper proposed a strategy for truncated-based LUT Multiplier (T-LUT ...

A Colorful Organic Photovoltaic Devices with a 5.48 % Power Conversion Efficiency
2019 26th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD), 2019We introduce a high-efficiency small-molecule organic photovoltaic (OPV) device which can emit different color with different thickness of the organic layer. In this OPV device, we can change the color output by simply tuning the thickness organic layer which forms microcavity cathode between layers of silver.

Efficient half-precision floating point multiplier targeting color space conversion
Multimedia Tools and Applications, 2019Color Space Conversion (CSC) in image processing applications, demands computationally simple floating point multipliers consuming less area and power. This necessitates the design and realization of the same meeting the aforesaid concerns. This paper makes one such contribution in the form of a New Bit Pair Recoding (NBPR) algorithm for realizing a ...

Energy conversion efficiency of solar cells coated with fluorescent coloring agent
Solar Energy Materials and Solar Cells, 1998A coating of fluorescent coloring agent (FCA) on the solar cells gives 30% increase in the energy conversion efficiency of the solar cell. This increase is attributable to the reduction of the reflection of incident light. The reflectances show low values at the excitation wavelengths, where the incident light is absorbed to excite the FCA.

On chip quantum dot based phosphor for efficient and tunable color conversion
CLEO Pacific Rim Conference, 2018CdSxSe1-x/ZnS (core/shell) quantum dots were used in combination with band-pass filters to convert blue light emitted from InGaN/GaN LEDs to different wavelengths. We present results to show this approach is a promising way of achieving tunable color conversion.

Derivation of efficient color-space conversion formulae for n -dimensional interpolation
SPIE Proceedings, 2003Conversions from one color-space to another are frequently used in image processing. Many conversion methods have been described mathematically, a few of which have been elevated to be international standards. However, for some conversions, purely mathematically based methods have been found wanting, and the method of measurement and interpolation ...
