/* This is the README file for libgphoto2/camlibs/clicksmart310. This README * is an integral part of the libgphoto2/camlibs/clicksmart310 library source * code and is distributed with that source code under the LGPL license, a copy * of which license may be seen in any of the source files in * libgphoto2/camlibs/clicksmart310, * or in the head directory of libgphoto2. */ The Logitech Clicksmart 310 camera is based upon a Sunplus spca50x chip, but its command sequences are quite different from those cameras supported in camlibs/spca50x. Hence, a separate library to support it. The camera will do 352x288 and 176x144 resolution settings. The camera (not the driver software) compresses all photos in JPEG format. High-resolution and low-resolution settings use different compression algorithms; not only are the low-resolution photos of smaller pixel dimensions, but they are also more highly compressed. The hardware supports the following listed actions, all of which are implemented here: -- JPEG photo format for both high-resolution and low resolution settings -- download all photos (gphoto2 -P) -- download any selected list of photos (gphoto2 -p) -- delete all photos on camera -- shoot a clip, which is saved by the OEM driver as an AVI file and we save the clip frames here as individual photos. If you want to see a movie from them, then try using the ImageMagick function "animate." The camera is "dual mode" and can also function as a webcam, supported by the spca50x kernel module. All streaming video and all capture abilities of the camera use isochronous data transmission and thus require support from a kernel module. The hardware will not support the capture options of gphoto2. The user should be aware that access to this camera through gphoto2 will fail if attempted with the spca50x kernel module already loaded. In that event the kernel module will already have claimed the camera. Thus, if you have the kernel module please make sure it is not installed. You may need to add spca50x to /etc/hotplug/blacklist to ensure that the module is not automatically installed when the camera is plugged in.
