27 | * Some documentation about various registers as determined by trial and error. | |
28 | * | |
b1a19c01 FS |
29 | * Register page 0: |
30 | * | |
31 | * Address Description | |
6f9b3312 FS |
32 | * 0x01 Red balance control |
33 | * 0x02 Green balance control | |
34 | * 0x03 Blue balance control | |
780d6170 FS |
35 | * The Windows driver uses a quadratic approach to map |
36 | * the settable values (0-200) on register values: | |
6f9b3312 FS |
37 | * min=0x20, default=0x40, max=0x80 |
38 | * 0x0f-0x20 Color and saturation control | |
780d6170 | 39 | * 0xa2-0xab Brightness, contrast and gamma control |
b1a19c01 FS |
40 | * 0xb6 Sharpness control (bits 0-4) |
41 | * | |
895d464d HG |
42 | * Register page 1: |
43 | * | |
44 | * Address Description | |
45 | * 0x78 Global control, bit 6 controls the LED (inverted) | |
48bb7315 HG |
46 | * 0x80 Compression balance, 2 interesting settings: |
47 | * 0x0f Default | |
48 | * 0x50 Values >= this switch the camera to a lower compression, | |
49 | * using the same table for both luminance and chrominance. | |
50 | * This gives a sharper picture. Only usable when running | |
51 | * at < 15 fps! Note currently the driver does not use this | |
52 | * as the quality gain is small and the generated JPG-s are | |
53 | * only understood by v4l-utils >= 0.8.9 | |
895d464d HG |
54 | * |
55 | * Register page 3: | |
56 | * | |
57 | * Address Description | |
58 | * 0x02 Clock divider 3-63, fps = 90 / val. Must be a multiple of 3 on | |
59 | * the 7302, so one of 3, 6, 9, ..., except when between 6 and 12? | |
60 | * 0x03 Variable framerate ctrl reg2==3: 0 -> ~30 fps, 255 -> ~22fps | |
61 | * 0x04 Another var framerate ctrl reg2==3, reg3==0: 0 -> ~30 fps, | |
62 | * 63 -> ~27 fps, the 2 msb's must always be 1 !! | |
63 | * 0x05 Another var framerate ctrl reg2==3, reg3==0, reg4==0xc0: | |
64 | * 1 -> ~30 fps, 2 -> ~20 fps | |
65 | * 0x0e Exposure bits 0-7, 0-448, 0 = use full frame time | |
66 | * 0x0f Exposure bit 8, 0-448, 448 = no exposure at all | |
48bb7315 HG |
67 | * 0x10 Gain 0-31 |
68 | * 0x12 Another gain 0-31, unlike 0x10 this one seems to start with an | |
69 | * amplification value of 1 rather then 0 at its lowest setting | |
895d464d | 70 | * 0x21 Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused |
48bb7315 HG |
71 | * 0x80 Another framerate control, best left at 1, moving it from 1 to |
72 | * 2 causes the framerate to become 3/4th of what it was, and | |
73 | * also seems to cause pixel averaging, resulting in an effective | |
74 | * resolution of 320x240 and thus a much blockier image | |
895d464d HG |
75 | * |
76 | * The registers are accessed in the following functions: | |
