Many of the gyroscopes, accelerometers, and other small components used
in recent mobile robots were originally developed for cell phones and
PDAs. This trend continues with Sharp's new LZ0P3721 CCD
camera. The new camera, intended for cell phone use, contains a 1
mega-pixel CCD that can output
color images up to 1180 x 880. A built in DSP that provides a digital
zoom function and an f2.8 lens are also included. The camera has a
maximum frame rate of 7.5fps. Best of all, the entire unit is only 14mm
x 12mm x 9.82mm in size, making it ideal for small robots. The
single-unit sample price is just 11,000 yen (about $93).
They do mention that the image format is UYVY, but this merely
indicates how the pixels are stored in memory, not the actual interface.
Obviously, the output format is digital, but does anyone have a clue as
to the particulars of the actual interface? This makes all the
difference for robotics use...
There's a little more info here but not much: http://sharp-world.com/products/device/ctlg/esite23/table/015.html
It indicates that there is a serial interface to the DSP and that
the image output is a UYVY 8bit parallal interface.
I also turned up this spec
sheet (PDF format) for a Sharp LZ0P3821 CCD chip which looks like it
may be similar to the one used in the camera.
And last, there's 19
page booklet (PDF format) that includes some general block diagrams
of the internal organization of Sharp's CCD cameras including the
LZDP3721 and other cell phone cameras.
