Past LCD‐TV generations suffered from a poor motion portrayal, causing the blurring of moving objects. Hence, various techniques have been implemented to improve their motion portrayal, of which the widespread introduction of motion compensated picture‐rate conversion in TV systems is an essential part. However, a careful design of such algorithms is critical, as otherwise very annoying artifacts may decrease their value. In this paper, we will give an overview of the key requirements for high quality motion‐compensated picture‐rate conversion, as implemented in state‐of‐the‐art system‐on‐chips, and visually illustrate the impact of individual measures on picture quality.
Abstract-Motion compensated interpolation (MCI) is crucial for motion portrayal improvement of modern displays, and film judder elimination. As MCI complexity grows, subjective optimization becomes cumbersome and elaborate. We present an objective metric that matches perception better than earlier measures and apply it to evaluate recent MCI algorithms.
Abstract— Active‐matrix OLED panels have inherent features that allow a higher‐quality image reproduction than LCD panels, i.e., high‐contrast, fast response time, and the capability to produce locally high peak luminance levels. We demonstrated a 13‐in.‐ink‐jet‐printed active‐matrix polymer‐OLED prototype for TV applications at SID 2004. This prototype is used as a carrier for studying video‐processing algorithms that take full advantage of the specific characteristics of OLEDs. Addressing schemes, gamut conversion, histogram‐based brightness control, and sparkle processing will be discussed.
