Subpixel Image Scaling for Color Matrix Displays
نویسندگان
چکیده
The perceived resolution of matrix displays increases when the relative position of the color subpixels is taken into account. ‘Subpixel rendering’ algorithms are being used to convert an input image to subpixel-corrected display images. This paper deals with the consequences of the subpixel structure, and the theoretical background of the resolution gain. We will show that this theory allows a low-cost implementation in an image scaler. This leads to high flexibility, allowing different subpixel arrangements and a simple control over the trade-off between perceived resolution and color errors.

Low-Cost Subpixel Rendering for Diverse Displays
Subpixel rendering increases the apparent display resolution by taking into account the subpixel structure of a given display. In essence, each subpixel is addressed individually, allowing the underlying signal to be sampled more densely. Unfortunately, naïve subpixel sampling introduces color aliasing, as each subpixel only displays a specific color (usually R, G, and B subpixels are used). As...
متن کاملLow Image Distortion Constrained Power Saving for OLED Displays
Organic Light Emitting Diode (OLED) displays have matured into current smartphones. How to prolong the lifetime of displays while preserving the display quality becomes a primary issue. In this paper, we propose a low image distortion constrained power-saving approach for OLED displays based on gamma correction and saturation scaling. We first investigate the impact of gamma correction and satu...
متن کاملA Fast Algorithm for High-Resolution Color Image Reconstruction with Multisensors
This paper studies the application of preconditioned conjugate gradient methods in high resolution color image reconstruction problems. The high resolution color images are reconstructed from multiple undersampled, shifted, degraded color frames with subpixel displacements. The resulting degradation matrices are spatially variant. To capture the changes of reeectivity across color channels, the...
متن کاملColor and Luminance Management for High-Resolution Liquid-Crystal Displays
A new method of color management is described which takes advantage of the high pixel density achievable with TFTLCDs. In this method, a calibration 10-bit look-up-table can be loaded into the monitor and implemented as a 2x2 spatial dither block to provide a 10-bit color palette for 8-bit color drive. Other subpixel dithering techniques are also described for monochrome and color high-resoluti...
متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
