Veiling glare and perceived black in high dynamic range displays.
A perceptual experiment was conducted to measure the visibility of black-level differences in the proximity of a bright glare source. In a controlled viewing environment, visual difference thresholds were adaptively measured using dark, shadow-detail images shown on a high dynamic range liquid crystal display while an external LED lamp was used to induce intra-ocular glare over a small range of...
متن کاملCamera and Visual Veiling Glare in Hdr Images
High-dynamic-range (HDR) images are superior to conventional images. The experiments in this paper measure camera and human responses to calibrated HDR test targets. We calibrated a 4.3-log-unit test target, with minimal and maximal glare from a changeable surround. Glare is an uncontrolled spread of an image-dependent fraction of scene luminance in cameras and in the eye. We use this standard ...
متن کاملThe effect of oncoming headlight glare on peripheral detection under a mesopic light level
Oncoming headlights sometimes cause disability glare that may obscure driver’s vision, both foveal and peripheral. The effects of disability glare on foveal vision have been investigated by many researchers for about 70 years and are generally specified by equivalent veiling luminance (e.g. Stiles and Crawford, 1937). However, few researchers have studied how disability glare impairs peripheral...
متن کاملThe New Veiling PhenomenonÐis it an Anorexic Equivalent? A Polemic
The paper deals with the new veiling phenomenon that initially began two decades ago in countries like Egypt and was taken up in increasing numbers by young educated and working women. The new veiling, however, is no longer restricted to the Middle East. This form of dress is now being adopted by many young Moslem women of various national backgrounds all over the world. The new veiling is an i...
متن کاملon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
