Title: Camera provided with image blurring correcting function
Inventor: IMADA SHINJI
IPC: G03B7/30
Filed: 1993-12-28
Abstract: PURPOSE:To improve an image blurring correcting effect all the more by preventing an exposure means from being actuated until output from an image blurring detecting means becomes smaller than a specified value. CONSTITUTION:When an image blurring correcting driving selection switch SWIS is turned on, an optical image is started to be stored in an image sensor included in a range-finding part 205. When a storage level attains a specified level, an optical image conversion signal from the image sensor is A/D converted and successively stored in a memory as a digital image signal a1. A phase difference (image blurring amount) (d) is arithmetically calculated based on an image signal a' before one sequence and the previous image signal a1. The image blurring amount (d) is compared with a specified threshold S. In the case of deciding that they are in the relation of d<=S, that is, in the case of deciding that what is left without correction is smaller than an allowable value, a main mirror 103 is made to be up so as to start exposure. In the case the image blurring amount (d) is larger than the threshold S, the storage of the optical image, the arithmetic operation of the image blurring amount (d) and the comparison of the image blurring amount with the threshold S are repeated by deciding that what is left without correction exists.

Title: Optical information transmitting device and light source
Inventor: HIRANO JUN
IPC: G02B5/20
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To solve a conventional problem of increased manufacturing cost which is due to the necessity of making an optical coupling mechanism highly precise by increasing the accuracy in the manufacturing stage of an optical information transmitting device because, with deviation caused in a coupling positional relation between a light emitting part and an optical fiber, a light beam having a spectrum outside a preliminarily designed region is made incident on the optical fiber, causing deterioration of transmitting performance. SOLUTION: The light emitting part 10 emits light in which the spectral distribution varies depending on the outgoing angle. In a light selecting part 20, light beams having a desired spectrum are selectively passed through among outgoing light beams 1 through a hole 21 preset in a positional range that selectively transmits such beams. The light beams 2 passed through the light selecting part 20 are coupled to the optical fiber 30 and transmitted. Thus, by using an inexpensive and simple structure, the light beams having a desired spectrum can be coupled to the optical fiber for transmission. As a result, it is possible to improve a transmitting rate and distance in optical transmission.
