[. . . ] Number of Loading Images during Multiple Image Input 333 Character Code Table For the case of character-related process items, recognized characters are output to an external device using a character code (base 10). Calculation method for output value (base 10) Number of upper level bits x 16 + number of lower level bits (of recognized character) = Output value (Examples) If the recognized character is "2", "50" is output. If the recognized character is "C", "67" is output. 9 Appendixes 334 Character Code Table FZ3 User's Manual Upper Limits of Processing Item Parameters For processing items where the upper limit value is changed based on the image size of the camera being used, the description of the upper limit value is expressed using "_MAX". Upper limit values for each camera are as follows. Parameters X_MAX Y_MAX W_MAX R_MAX Description The max value in the X-axis orientation The max value in the Y-axis orientation Maximum width Maximum radius For 0. 3 megapixel cameras: 639 479 239 (straight line W = 319) 239 (circle/ellipse R1=319) (X_MAX+1) * (Y_MAX+1) = 307200 479 For 2 megapixel cameras: 1599 1199 599 (straight line W = 799) 599 (circle/ellipse R1=799) (X_MAX+1) * (Y_MAX+1) = 1920000 1199 For 5 megapixel cameras: 2447 2043 1021 (straight line W = 1223) 1021 (circle/ellipse R1 = 1223) (X_MAX+1) * (Y_MAX+1) = 5003712 2043 A_MAX Maximum area Maximum number of lines that can be loaded Y_PMAX 9 Appendixes FZ3 User's Manual Upper Limits of Processing Item Parameters 335 About Memories Usable with FZ Series The following types of memory can be used with FZ. On-board memory This is the area where images are temporarily stored when logging images using the logging function. This uses ring memory and if the maximum number of save images has been reached, images are overwritten starting with the oldest. [. . . ]
