Abstract: front page image
(EN)An image processing device adjusts a quantization bit number of image data, based on the dynamic range of each block, at the time of outputting coded image data by quantizing the image data of a current frame by block. Therefore, coding errors can be reduced without increasing the capacity of the coded image data, and a liquid crystal response speed can be suitably controlled without applying an unnecessary excess voltage due to influence of the coding error.
(FR)La présente invention concerne un dispositif de traitement d'images qui modifie le nombre de bits de quantification des données d'image selon la plage dynamique de chaque bloc en quantifiant les données d'image du cadre courant bloc par bloc lors de la production des données d'image codées. Ceci permet de réduire les erreurs de codage sans accroître la capacité de données d'image codées et, par conséquent, de commander efficacement la vitesse de réaction des cristaux liquides sans appliquer de surtension inutile liée à l'erreur de codage.
(JA) 本発明に係る画像処理装置は、現フレームの画像データをブロック毎に量子化して符号化画像データを出力する際、各ブロックのダイナミックレンジに基づいて画像データの量子化ビット数を調整するので、符号化画像データの容量を増加させることなく符号化誤差を低減し、符号化誤差の影響による不要な過電圧を印加することなく液晶の応答速度を適切に制御することができる。
