There is a new sensor structure that introduce by Panasonic to replace color filter by color splitter. This kind of sensor remove general color filter and add the color deflector before the diode. The conventional color filter would cause 50%~70% light loss and new sensor reduce lots of the light loss. The following pictures show how it works. The device can also be manufactured using current semiconductor fabrication processes. It doesn’t use special materials or processes. It’s a great news to bring this sensor to realization. ...

I’ve search on internet and get quick steps for whole process to generate Makefile by Autotools. autoscan . // scan the folder cp configure.scan configure.ac // copy the configure.scan to configure.ac vi configure.ac // edit the configure.ac // add AM_INIT_AUTOMAKE(hello,1.0) in configure.ac // this is required marco for automake aclocal // execute aclocal to generate aclocal.m4 autoconf // execute autoconf to generate configure autoheader automake –add-missing // run automake touch NEWS; touch README; touch AUTHORS; touch ChangeLog // create related documents automake –add-missing // run automake again ./configure // execute the configure to generate Makefile make // execute make According to the steps, I get more hint to modify the related files for my target.

Official gstreamer packages version I use is 1.0.5: gstreamer core -> Modify Makefile and patch, compile ok. - gst-plugins-base -> Modify Makefile and patch, compile ok. ...

In previous articles, I tried to build the pjsip package, but it’s hard for me to make sure the package is work correctly because of my lacking knowledge of sip. Then I try to be more familiar with how the sip works. First, prepare a PC and install the switch on it. We have two popular choices, one is Asterisk and another one is Freeswitch. I choose the Freeswitch because there is a precompiled binaries for win7 already. ...

Before trying to make the pjsip work on my embedded device, I build the related libraries on PC as the reference. My environment is based Ubuntu 10.04. See the following guide. http://trac.pjsip.org/repos/wiki/Getting-Started/Autoconf The notes of packages building: - ALSA and OpenSSL libraries are optional and I do not install for first. - SDL, I download the version 2.0 and do “./configure”, “make; make install” to install the package to system. If we encounter privilege problem, please add sudo. ...
