    Experts: why the light is white? The secret.

    Well, I would just say that it is simple and poor in terms of photography, but good looking for dash cam "auto white balance". They are choosing the brightest part of the image as the point that is white.

    I understand that this post is old, but for the sake of reality. While you right in terms of the full frame photo cameras, you are totally wrong for the small sensors. 1. We are not really talking of the DOF (while technically we are), we are talking about hyperfocal distance, which is DOF from...

    Koonlung Angel Eye N2/N2G

    I have no idea about this particular chips, but from my experience with Cortex series, will be from 2 to 10$ at most, but I bet that initial cost of commercial SDK (and other non chip stuff like support?, firmware?) will make it a lot more expensive for small factories. Not sure if Chinese...

    Made my first compilation. . .

    Nothing personal. I'm often driving in business trips in garden state, so I was worrying that I might be breaking the law if I do that.

    Thanks. But you are wrong, the reference you posted is about "keeping to the right at the intersection" which means you cannot pass (driving to the left part of the road to pass), but says nothing about lane changes.

    Nice compilation, the only question, could you provide code (link to the law) that prohibits lane change in the intersection, please? The reason I'm asking is that California Vehicle Code have nothing to say about it, it is wives tale here, but I hear it all the time. However, as with any lane...

    Good lens on chinese dash cams?

    Depth of Field and Hyperfocal Focusing depends on the F (Focal length), f (aperture) and sensor size. Hyperfocal Focusing for different sensor sizes, same frame coverage: Let's look at the sensors 1/2.7'' and 2/3'', corresponding crop factors are 6.44 and 3.93, So lens focal lens multiplier is...

    Good lens on chinese dash cams?

    Totally agree with the lens point, but as for the sensor size I would like to notice that "As sensor size increases, the depth of field will decrease for a given aperture"!

    Idea on the DIY dashcam system

    Sure hundreds of dashcams available, but for most of them the night time quality is not very good. And for a few with the good glass lens and an good night quality the price is 195+. That surprises me, because of the calculations above, A lot more powerful chipset + separate camera with hardware...

    Idea on the DIY dashcam system

    While trying to decide which cam I need, I was reading russian forums for the BlackVue 500 hacking progress. Thinking of what can be done in that MV embedded linux I got an idea. My wife have Logitech C920, and that beast have hardware h.264 encoding 1080p x30fps. So, technically it shouldn't...

    Eeyelog HDW001

    Looks like they just renaming the cameras from HDW001 and HSW002 (a2s processor) to EHD60, EHD63 and EHD65. The EHD60 brochure already posted is the new one. Have no idea what's different. BTW, Looks like russian Texet (mentioned in the GS6000 thread) now have almost the same camera on the...
