- GSMART 300 DRIVER FOR GPHOTO2
- =============================
-
- Note : this camera is also know as "Casio LV-10",
- under the same vendor and product IDs
- (Model actually tested)
-
- This is a very basic camera which enables to take pictures,
- delete last picture or delete all pictures.
-
- Pictures (JPEG format) can be stored in two sizes : 640x480 or 320x240.
- In fact, this is not exactly true. The pictures are all 640x480,
- but the "smaller" ones are just poor quality, so that it becomes
- decent only after resizing to 320x240.
- Thumbnails are downloadable from the camera in YYUV format
- for "big" pictures ONLY.
-
- To perform these operations, the Windows driver uses an
- interpolation software which acts as this :
-
- For lower quality, 640x480 pictures are downloaded, and
- converted to 320x240. In the same way, 80x60 thumbnails
- are generated.
-
- For higher quality, 80x60 thumbnails are downloaded in YYUV
- and converted to bitmap. Strangely enough, 640x480
- picture are also converted into pictures of the same size
- by the interpolation software, resulting in a disk-size
- about 2 times greater ! (but no visible loss of quality)
-
- The gsmart300 driver for gphoto just outputs the higher quality
- pictures as they are stored in the camera, as well as bitmap
- thumbnails.
- Lower quality pictures are left 640x480, and no thumbnail
- is provided.
