Hybrid Exposure Combination of follow focus and quenching systems.
Inertia System Rack and pinion system with zinc inertia gear, coupled to blade-opening
Walking Beam; used to reduce blade opening speed.
Infrared Invisible portion of electromagnetic spectrum. Used in Joshua exposure
calculations since many fabric dye colors have similar IR reflectivity values.
Inhibits Prevention of Camera operation when bad/no picture would result (storage
chamber full, end of pack, strobe not charged).
Integrator Electronic circuit for summing and storing measured light values.
(Ambient, Hybrid)
Interconnect Flex (See Flex, Interconnect).
IR Abbreviation for infrared.
IR Reflectivity Property of a material to reflect/emit infrared radiation. Used in Joshua
exposure calculations since many fabric dyes of differing colors possess
similar IR reflectivity values.
Jam Film frame misfeed and incomplete transport into storage chamber.
Jog, Reverse Motor Brief, initial CCW rotation of Motor to release Recock Latch, allowing VF
Blind to block VF window and Recock Link to lift Taking Mirror.
Joshua Code name for Joshua Camera during development.
LED Abbreviation for Light Emitting Diode.
Logic Switch Multi-element wireform switch in Joshua, controlling Exposure Trim,
Self-Timer, End of Pack, DKEC, S1A-S1B, Film Speed and Full Chamber
functions.
Look-Up Table In the Joshua microprocessor, a stored collection of ambient and Wink
reflectance values arranged as rows and columns, the intersections of which
provide optimum exposure data for thousands of different photographic
situations.
Mainframe Primary molded frame on which all other camera subassemblies, frames and
structures are mounted.
MCU Circuit designation of microprocessor IC in Joshua Camera.
Microprocessor (Micro) Integrated circuit chip containing CPU elements of control logic, decoding,
arithmetic processing and memory.
