Title: Image blur detector
Inventor: OKADA NAOSHI
IPC: G03B7/099
Filed: 1990-03-26
Abstract: PURPOSE:To allow the detection of an image blur even in fog light by disposing an area sensor for image blur detection in a position where subject light is not shielded in the fog light. CONSTITUTION:The area sensor 8 for image blur detection is disposed on the bottom of a mirror box so as not to shield the subject light even in the fog light and receives the subject light reflected by a shutter curtain film 15 before exposing and by a film plane 5 after the start of exposing. An optical system 9 for image blur detection forms the subject image formed on the film 5 to the sensor 8 and the sensor 8 converts the luminance distribution of this image to an electric signal and outputs the signal to an image blur computing device 10. The computing device 10 takes the sensor output therein at every other prescribed time and calculates the direction of the blur and the quantity of the blur by comparing the two luminance distributions within the different time. A correcting lens 13 is driven by an actuator 14 according to this value.
