it's in French, and when translated (by Babel Fish Translations) says this: (both funny and informative read)
The case of good size of ViviCam 3725, far from dimensions Lilliputians of some of its competitors, hides a camera numerical trimégapixel. It offers an excellent catch in hand, the bulge of the housing of the piles improving gripping of the apparatus. In the same order of idea, the fingers naturally find their place for the control of the zoom (the same button is used for navigation in the menus) and of release. The aiming is carried out with the choice in the reflector view finder or on screen LCD. This one remains relatively readable in outsides (recess + adjustment of the luminosity), but suffers from an insufficient frequency of cooling. So aiming LCD of subjects moving will be unpleasant even impossible.
The apparatus has a sensor of 3,34 mégapixels, delivering images of a resolution going of 640 X 480 to 2 048 X 1 536 pixels, to the maximum. To this choice of resolution that of the level of compression is added: Tiff not compressed and three levels of compression JPEG. This sensor is been useful by an optics autofocus zoom 4x, equivalent with one 35-140 in 35 mm (silver traditional).
The quality of the images is of a good level, with one made precise of the details, an exposure not burning too the strongly exposed zones and a correct colorimetric balance, these qualities being found during an exposure to the flash. The transfer of the images is carried out by port USB (superfluous installation of the pilot under Windows XP), the video exit authorizing the direct visionnage on the television set. To the catch of standard sight, other useful modes are added: macro (in fact of the brought closer photograph, from 16 to 60 cm), programs result (portrait, landscape, photograph of night, texts), audio recording and/or video (in 304 X 240 pixels) and retarder.
On the other hand, ViviCam 3725 is not a Formula 1 of the photograph. It takes him 6 seconds to be initialized and 7 seconds of treatment between each image taken beyond the capacities of the mode " gust " (2 to 4 images in high resolution at a rate of a image/seconde approximately). As for the treatment of a photograph in tiff, it requires 40 to 50 seconds! It also suffers from a problem of autonomy. In mode tiff with maximum resolution, the memory board Compact Flash delivered of 16 Mo makes it possible to record one stereotype, this capacity being able to reach 7-9 with difficulty images, in JPEG slightly compressed. It will thus be necessary to acquire of a memory board dimensioned better to have a reasonable autonomy. This autonomy is also taken at fault side food. Thus a set of four alkaline piles AA did not hold more than 30 minutes, screen LCD in function. There still, the acquisition complementary to refillable accumulators AA (1 600 to 1 800 mAh) is essential not to be ruined out of piles.
