 196     Notes on Canon ISO & CHDK ISO overrides.
 197     ========================================
 198     (philmoz Aug 2013)
 199 
 200     Canon P&S cameras use two different values for ISO in the firmware.
 201         - the ISO value displayed on screen & stored in the image EXIF, generally referred to as the 'market' ISO
 202         - the value used to program the sensitivity of the sensor and/or set the image tone curve, the 'real' ISO
 203 
 204     The firmware uses the APEX system for ISO (as well as aperture, shutter speed and luminance).
 205     See - http://dougkerr.net/pumpkin/#Optics - APEX - The Additive System of Photographic Exposure.
 206     The Canon firmware scales the Sv (speed value) by multiplying values by 96 - referred to as Sv96 below.
 207 
 208     Conversion of ISO to/from Sv96 (from the above linked PDF)
 209     ----------------------------------------------------------
 210         Sv = log2(ISO / 3.125)      ==>     Sv96 = log2(ISO / 3.125) * 96
 211         ISO = pow(2, Sv * 3.125)    ==>     ISO = pow(2, Sv96 / 96 * 3.125)
 212 
 213     In the implementation below 3.125 is represented as 100/32, 
 214     and log2(x) is calculated as log(x)/log(2), where log is the natural log function found in the firmware.
 215 
 216     Relationship of 'real' to 'market' values.
 217     ------------------------------------------
 218     In most cases the following equation holds:
 219         Sv96_real = Sv96_market - 69
 220     In other words the 'real' value is approx. 1/3 stop lower than the market value.
 221     On some cameras, when the lowest ISO is set manually on the camera, the equation is:
 222         Sv96_real = Sv96_market - 78
 223     The difference is less than 1/10th of a stop, so the value 69 is used in the CHDK override code.
 224 
 225     Note: some cameras have a different offset (e.g. IXUS700 uses 'real = market - 20')
 226           in this case override the conversion values in the platform_camera.h file
 227 
 228     Based on the above equations we can determine that:
 229         ISO_real = ISO_market * pow(2, -69/96) ~= ISO_market * 1.65
 230     and ISO_market = ISO_real * pow(2,  69/96) ~= ISO_real * 0.61
 231     The derivation of this equation is left as an exercise for the reader :)
 232 
 233     Setting ISO on the camera.
 234     --------------------------
 235     Four PROPCASES are used for ISO settings
 236         PROPCASE_ISO_MODE       = ISO value when ISO set manually, 0 for AUTO ISO
 237         PROPCASE_SV             = 'real' Sv96 value for ISO
 238         PROPCASE_SV_MARKET      = 'market' Sv96 value when ISO set manually
 239                                 = Sv96 value for camera 'base' ISO (50,100 or 200) when using AUTO ISO
 240         PROPCASE_DELTA_SV       = 0 when ISO set manually
 241                                 = 'market' Sv96 - PROPCASE_SV_MARKET when using AUTO ISO
 242 
 243     From the above:
 244         'market' Sv96 = PROPCASE_SV_MARKET + PROPCASE_DELTA_SV
