Title: Innovations by James K Lim
Introduction
James K Lim is an accomplished inventor based in Somerville, MA (US). He has made significant contributions to the field of photography through his innovative patents. With a total of 2 patents, Lim has developed systems that enhance photographic exposure and flash control.
Latest Patents
One of his latest patents is the Variable Proportional Fill Flash. This photographic exposure and flash fire control system initially measures ambient scene light and subsequently utilizes the results of that measurement to control the amount of artificial illumination provided during the exposure interval. The initial measurement of ambient scene light below a first select level provides for a maximum flash output, while the initial measurement above a second select level greater than the first provides for minimum flash output. The system allows for a flash output that progressively varies between the minimum and maximum outputs in inverse relation to the measured ambient scene light.
Another notable patent is the Exposure and Flash Fire Control System. This dual mode range responsive system operates based on the distance of the photographic subject from the camera. For subjects located within a near distance range, a flash fire signal is provided during the exposure interval when the aperture size corresponds to the camera-to-subject distance. Conversely, for subjects located within a far distance range, the flash fire signal is provided after the shutter blades reach a maximum aperture position, with the flash output being quenched based on scene light detection.
