Neste artigo, o impacto da exibição na avaliação da qualidade é abordado. Experimentos de avaliação subjetiva de qualidade foram realizados em monitores LCD e CRT. Dois conjuntos de imagens estáticas e dois conjuntos de imagens em movimento foram avaliados usando um protocolo ACR ou SAMVIQ. Ao todo, oito experimentos foram conduzidos. Os resultados são apresentados e discutidos, algumas diferenças são apontadas. No que diz respeito às imagens em movimento, estas diferenças parecem dever-se principalmente a artefactos móveis do LCD, como a desfocagem do movimento. O desfoque de movimento do LCD foi medido objetivamente e com experimentos psicofísicos. Uma métrica de desfoque de movimento baseada nas características temporais do LCD pode ser definida. Foi então desenhado um modelo de previsão que prevê as diferenças de qualidade percebida entre CRT e LCD. Este modelo baseado em desfoque de movimento permite a estimativa da qualidade percebida no LCD em relação à qualidade percebida no CRT. As soluções técnicas para o desfoque de movimento do LCD podem, portanto, ser avaliadas em conteúdos naturais por este meio.

Abstract: In this paper, the impact of display on quality assessment is addressed. Subjective quality assessment experiments have been performed on both LCD and CRT displays. Two sets of still images and two sets of moving pictures have been assessed using either an ACR or a SAMVIQ protocol. Altogether, eight experiments have been led. Results are presented and discussed, some differences are pointed out. Concerning moving pictures, these differences seem to be mainly due to LCD moving artefacts such as motion blur. LCD motion blur has been measured objectively and with psycho-physics experiments. A motion-blur metric based on the temporal characteristics of LCD can be defined. A prediction model have been then designed which predict the differences of perceived quality between CRT and LCD. This motion-blur-based model enables the estimation of perceived quality on LCD with respect to the perceived quality on CRT. Technical solutions to LCD motion blur can thus be evaluated on natural contents by this mean.
