11 On 08/23/2007, I discovered a new camera with USB ID 0x2770:0x913d. The
12 basic functions of this camera are the same as those of the 0x2770:0x905c
13 cameras which are the main ones supported in libgphoto2/camlibs/digigr8, but
14 there are some small differences. For a complete description and discussion
15 of the 0x2770:0x913D camera, therefore, the reader should also read
16 README.905C. Only the basic features and differences with the
17 previously-supported 0x2770:0x905C cameras are listed here:
19 Features of the Suprema Digital Keychain Camera:
21 -- 640x480 and 320x240 resolution settings
22 -- supports gphoto2 --capture-preview option (presumed that the size
23 of the output image can be adjusted in code, default
24 ` 320x240; see README.905C for details of that.
25 -- apparently does _not_ support multiframe AVI capability, or if so
26 it is not mentioned in the written manual.
27 -- a setting does exist for shooting three frames with one shutter
28 press, but three only, not more.
29 -- has a viewfinder and preview window on the back, which is very
30 pretty but presumably eats battery.
31 -- saves photos in volatile SDRAM, so don't let the batteries die.
32 -- permits deletion of individual photos on the camera, by pushing
33 some buttons. This feature is not present on the SQ905C
34 cameras and is a big difference. Because of the way
35 this deletion is done, the function which counts photos
36 needed a serious rewrite to accommodate the deletion.
37 It will probably not ever be possible, unfortunately, to
38 support deletion of any photos or images on the camera, by
39 means of software control from the computer.
40 -- webcam functionality. The webcam function is obviously
41 supportable (gphoto2 --capture-image uses it to shoot one
42 frame), but libgphoto2 does not do webcams, so that can't be
45 As a further note, the gphoto2 --capture-image USB command when used with an
46 0x2770:0x913D camera will _not_ delete the images already on the camera. This
47 means one does not have to worry about that happening; it also means that there
48 is no way known to implement the gphoto2 -D option for these cameras.
51 On 10/13/07 I discovered that the Sakar Styleshot (Sakar ID no. 28290 or 28292)
52 is also supported, and I have added it to the list of cameras in library.c.
53 Aside from appearance, the main difference between the Styleshot and the
54 Suprema described above is that the Styleshot has an internal rechargeable
57 On 12/23/07 the Sakar Spiderman (no. 92045) has been reported by Martin Laberge
58 <mlsoft@videotron.ca>. THERE IS POTENTIAL NAME CONFUSION WITH THIS CAMERA. The
59 Sakar Amazing Spiderman (no. 94044) has in it a JL2005C chip which is currently
60 not supported in libgphoto2. Buyer beware!
62 PLEASE TEST THE STANDALONE RAW PHOTO CONVERTER/DISPLAYER
64 An experimental program for processing raw files into finished photos is
65 available now, in gphoto2/trunk/playground/raw_converters/sq_raw_converter
66 Please try this program. If the results are good, I will incorporate the
67 routines used there directly into libgphot02/camlibs/digigr8. I like the
68 results, but they need testing.
73 None. For a more complete discussion of this issue, the reader is referred to
74 README.905C and to the statements of the LGPL license regarding warranty.
