Re: Proyector Hitachi TX200
Y perdon por esta suerte de traduccion...
Picture quality check - class highest 1,200ANSI lumen television application possibly as for nominal maximum brightness 1,200ANSI lumen. It is brightness of top class, as this price range, but to tell the truth from tip generation PJ-TX100J you learned this brightness efficiency.
PJ-TX200J, TH-AE900 similar, generation new Epson make D5 liquid crystal panel use do be be, but 10% pixel 開口 numerical aperture improvement carry out this new liquid crystal panel adoption to accompany brightness efficiency improvement be (TH-AE900 as for D5 panel adoption upon attendant 100ANSI lumen brightness improvement).
Furthermore, maximum brightness of the 1,200ANSI lumen opens the lens iris maximally, when color temperature mode making " high bright ", has reached the value which is actualized. Actually, when you use with this largest brightness mode, if at the extent where the inside of the room in a flash becomes bright, it is variety program and sport relay even under fluorescent light illuminating, it can see normally. " While to do the meal under illuminating, even the television application that you see ", there is a possible brightness potential in the PJ-TX200J.
By the way, when squeezing two iris mechanisms of the lens iris and the active iris to the maximum, brightness goes down to the 400ANSI lumen. The numerical value which as for largest contrast efficiency you call nominal 7,000:1, appears extremely largely is put out, but this makes the lens iris the largest contraction, controls the active iris maximally to make " automatic 2 ", when setting color temperature mode " highly bright ", value. When you mention 7,000:1, even whether the even DLP projector and the LCOS projector 遙 it is the value which is surpassed, but because this is contrast with the black at the time of the 400ANSI lumen which two iris mechanisms the maximum is squeezed and white at the time of the 1,200ANSI lumen which opens the dual iris together, it is not the case that it can do 7,000:1 contrast expressions in 1 frame.
The ネイティヴコントラスト of the PJ-TX200J is thought it has reached the value which corresponds to 750:1 where it is D5 panel itself nominal contrast efficiency. Also with respect to of actually bodily sensation was about that. Furthermore the PJ-TX200J first dynamic iris control mechanism (the active iris) becomes the model which is installed as the Hitachi foam/home theater machine. One generation, the timing which starts this function is the case that it is late from other companies, but as expected how the capability? Actually you tried verifying, whether with some kind of effect appears " off " and " automatic 3 gradual setting of 1 " and " automatic 2 " thoroughly, but as for feeling it is usable, off " " " automatic 1 " only. As for " automatic 2 " in order to change the contraction drastically according to the luminance level of image, change of the light and darkness is very extreme. As for being extreme when change of the light and darkness of the scene is large as anyhow, this mechanical contraction control is late to the change of the scene extremely. For example, when from the scene of the extremely dark cave, it changes to the scene where the outside which advances completely difference simultaneously is bright, about 0.5 seconds being required, becoming at last proper brightness, the condition that the bright scene is drawn. Looking at image in this operation, you feel strange feeling. Already unless iris control is accelerated a little, as for the active iris of " automatic 2 " the mode which is specifications declared because of 7,000:1 catalogs, with it does not have the impression which is said you do not obtain. Control width somewhat becomes loose, as for " automatic 1 ", as operational speed somehow been in time, does not have the unnaturalness like " automatic 2 ", can use properly. It is the black floating which becomes matter of concern, but as for the PJ-TX200J black is raised to the brightness to maximum brightness being high partly due. Black and the darkness of the room, because black as a projection image on the screen there is brightness differential, when the black territory is many in image, originally the gray which shines sluggishly from the place of expectation of black is felt. But, if the lens iris is dropped to 5 and the active iris is set to automatic 1, this stops becoming the voluminosity air. Of course there is no brightness of the 1,200ANSI lumen as absolute brightness.
Gradation expression is collected balance very well, (the automatic iris up to =1, below same). After standing on the fact that it is the aforementioned black floating, pure tuning has done, the nature and linear is possible the fact that gradation expression is felt to the image which comes out. Utilizing dual iris mechanism, when making the black floating decrease, good quality of this gradation characteristic balance is maintained.
As for tendency of coloration with natural, excessive primary color emphasis you do not feel. There is a moderate sharpness even in the shining of pure color type. We want just a little depth already in red, but if you think of that the illuminant is the extra high tension mercury based lamp you think it is persevered. There is no yellow green impression even in coloration of beige, is fresh with the vitality can be felt extent well. Also color depth was deep, also the gradation of mixed color had been decided gently. It photographs near the center of the PC picture of HDMI connection. Benefit of the large aperture lens or focusing efficiency and chromatic aberration in the picture center it is little, it is worthy of to special mention
As for panel resolution with the 1,280×720 dot, as for pixel form the feeling elliptic like the right rising. Because there is no pixel lattice decrease function like the TH-AE900, somewhat, there are also times when the lattice impression is felt in expression of the slanted line with the image which the color edge like animation is clear but with photograph taken on the spot image it is not the extent which becomes matter of concern. Near the center of the image where the gaze gets together chromatic aberration is well held down very, also focusing is decided clearly, is drawn beautifully the pixel one 1 Tsuga without becoming blurred. But, if it becomes image outer circle, the extent which becomes (as for focusing there is a tendency where) chromatic aberration of those which are agreeable comes out strongly, with outermost lap approximately 1 dot, green it seems that on the right red slips on the left. Almost it does not become matter of concern which is photograph taken on the spot image, but when projecting information in printing with PC image, perhaps it becomes matter of concern.
