To All:

Buffer Size Investigation for K750 CID 49 is Finished!

MAX Buffer Size for K750 CID 49 is 601.6 KB (camera turns off at higher values, even at 601.7 KB).

here are the buffer size values used in some popular drivers:

SARMAD 5.8

In the driver file we see this:

//-- JPEG buffer sizes (only used for ITP)
cam_ss_jpeg_buf_size_1=3A98; // 15 KB buffer for 100x60 snap
cam_ss_jpeg_buf_size_2=88B8; // 35 KB buffer for 160x120 snap
cam_ss_jpeg_buf_size_3=186A0; // 100 KB buffer for 320x240 snap
cam_ss_jpeg_buf_size_4=249f0; // 150 KB buffer for 640x480 snap
cam_ss_jpeg_buf_size_5=61A80; // 400 KB buffer for 1280x960 snap
cam_ss_jpeg_buf_size_6=927C0; // 600 KB buffer for 1600x1200 snap
cam_ss_jpeg_buf_size_7=927C0; // 600 KB buffer for 1632x1088 snap
cam_ss_jpeg_buf_size_8=927C0; // 600 KB buffer for 1632x1244 snap

but the size defining values are not real. I don't know why but Sarmad uses 1000 to define 1 MB, not 1024.

So here are the real values for Sarmad's Buffer sizes:

//-- JPEG buffer sizes (only used for ITP)
cam_ss_jpeg_buf_size_1=3A98; // 14.6 KB buffer for 100x60 snap
cam_ss_jpeg_buf_size_2=88B8; // 34.2 KB buffer for 160x120 snap
cam_ss_jpeg_buf_size_3=186A0; // 97.7 KB buffer for 320x240 snap
cam_ss_jpeg_buf_size_4=249f0; // 146.5 KB buffer for 640x480 snap
cam_ss_jpeg_buf_size_5=61A80; // 390.6 KB buffer for 1280x960 snap
cam_ss_jpeg_buf_size_6=927C0; // 585.9 KB buffer for 1600x1200 snap
cam_ss_jpeg_buf_size_7=927C0; // 585.9 KB buffer for 1632x1088 snap
cam_ss_jpeg_buf_size_8=927C0; // 585.9 KB buffer for 1632x1244 snap


Raiderski 6.5 T4

Raiderski uses same buffer sizes as Sarmad.


lpachuong A4A 6.4

In older versions lpachuong used same buffer values as sarmad, but in 6.4 he had to increase the buffer size value for for 1632x1244 snap, so here are 6.4 values:

cam_ss_jpeg_buf_size_1=3A98; // 14.6 KB buffer for 100x60 snap
cam_ss_jpeg_buf_size_2=88B8; // 34.2 KB buffer for 160x120 snap
cam_ss_jpeg_buf_size_3=186A0; // 97.7 KB buffer for 320x240 snap
cam_ss_jpeg_buf_size_4=249f0; // 146.5 KB buffer for 640x480 snap
cam_ss_jpeg_buf_size_5=61A80; // 390.6 KB buffer for 1280x960 snap
cam_ss_jpeg_buf_size_6=927C0; // 585.9 KB buffer for 1600x1200 snap
cam_ss_jpeg_buf_size_7=927C0; // 585.9 KB buffer for 1632x1088 snap
cam_ss_jpeg_buf_size_8=96640; // 601.5 KB buffer for 1632x1244 snap


Tonight I will test original Sarmad 5.8 with MAX possible buffer size (601.6 KB) as in original it has 585.9 KB buffer and that is not enough very often.

Which driver did you use yesterday?

Good morning everyone and have a nice day.

It is nice to hear that you are pleased with A4A's series. If You have any problems with it please point them out. Thanks a lot.

lpachuong:) could you make a simple driver? without supermode functions?:)
just manual focus, enm, em, and... maybe shutterspeed and exposure.. there are too many functions in my opinion:)

Hi. Here is the functions on A4A:


EV: -2.0: Change GREEN
-1.7: Change MAGENTA
-1.3: Change blue
-1.0: Change yellow
-0.7: change zoom
-0.3: change iso
0.0: focus: 1.0 auto 1.1 infinitive 1.2-4.0
+0.3: change exposure: EM/ENM is ready. read exposure information below.
+0.7: light metering/spot: 1.0 - no spot 1.1 spot on
+1.0: change shutter speed (1/5000' - 1/6' with daylight, 1/5 to 2' or more at night/low light)
+1.3: change shutter speed which can be combined with iso (1.0 -4.0 from 1/20' to 2' - Thanks to Jonaugust )
+1.7: Change saturation
+2.0: change scence

As you take a look carefully then you will see -EV just for changing colour and the two nearest valut to 0 are ISO and zoom which are not used regularly. All the +EV or useful: exposure to control overexposure, light metering: good effect, and shutterspeed here. They are the main feature in sm in my opinion so i put them side-by-side. And always use macro, normal quality for em off, fine quality for em-on. Hope this can help you

After investigations I optimized buffer values and here they are:

//-- JPEG buffer sizes (only used for ITP)
cam_ss_jpeg_buf_size_1=5000; // 20 KB buffer for 100x60 snap
cam_ss_jpeg_buf_size_2=B400; // 45 KB buffer for 160x120 snap
cam_ss_jpeg_buf_size_3=19000; // 100 KB buffer for 320x240 snap
cam_ss_jpeg_buf_size_4=2D000; // 180 KB buffer for 640x480 snap
cam_ss_jpeg_buf_size_5=64000; // 400 KB buffer for 1280x960 snap
cam_ss_jpeg_buf_size_6=96666; // 601.6 KB buffer for 1600x1200 snap
cam_ss_jpeg_buf_size_7=96666; // 601.6 KB buffer for 1632x1088 snap
cam_ss_jpeg_buf_size_8=96666; // 601.6 KB buffer for 1632x1244 snap


here are 2 versions of A4A 6.4:

1) with optimized buffer settings above:
http://downloads.wow-info.net/test/camdriver0.DAT

2) with 602 KB buffer size:
http://downloads.wow-info.net/test/camdriver0_602KB_buffer.DAT

both are designed just to test. 602 KB version wont run on CID 49 K750, but I am interested in if CID 36 K750/W800 has same buffer sizes.

So to everyone who has CID 36 K750/W800, test both drivers and tell us if camera turns off automatically or not

hmm:) i know what every of that functions do(almost, to be onest:D)... just i think that many users(including me:D) prefer a simple driver, without supermode f-tions... that's why i sugested you to make a simple driver:)
P.S: thanks for this quick replay:)

inter4ever
Just don't change EV and Zoom values and you will have simlpe automatic driver
