Abstract

Abstract An image pickup device according to the inven­tion mainly comprises image pickup means (1), fluctuation stabilizing means (11), exposure time control means (13), and computing means (12). The image pickup means (1) sends a video signal to the fluctuation stabilizing means (11) in which unnecessary fluctuation of the image output by the image pickup means (1) is stabilized depending on a stabilization reference value. The exposure time control means (13) serves to control an exposure time used for the image pickup means (1) depending on the exposure time reference value. The computing means (12) functions to compute the stabilization reference value and the exposure time reference value. The design and function results in realizing an image pickup device for producing a visually natural image.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 45 words
An image pickup device being characterized by comprising an image pickup means (1), control means (13) for controlling an exposure time used for said image pickup means (1), and stabilizing means (11) for stabi­lizing unnecessary fluctuation of an image output by said image pickup means.
Claim 2
Dependent Claim 45 words
An image pickup device being characterized by comprising an image pickup means (1), control means (13) for controlling an exposure time used for said image pickup means (1), and stabilizing means (11) for stabi­lizing unnecessary fluctuation of an image output by said image pickup means.
Claim 3
Dependent Claim 71 words
An image pickup device being characterized by comprising image pickup means (1), stabilizing means (11) for stabilizing unnecessary vibration of an image output by said image pickup means (1) according to stabilization reference value, control means (13) for controlling an exposure time used for said image pickup means (1) according to an exposure time reference value, and computing means (12) for computing said stabilization reference value and exposure time reference value.
Claim 4
Dependent Claim 71 words
An image pickup device being characterized by comprising image pickup means (1), stabilizing means (11) for stabilizing unnecessary vibration of an image output by said image pickup means (1) according to stabilization reference value, control means (13) for controlling an exposure time used for said image pickup means (1) according to an exposure time reference value, and computing means (12) for computing said stabilization reference value and exposure time reference value.
Claim 5
Dependent Claim 60 words
The image pickup device claimed in claim 2, wherein the computing means (12) can employ two stabilization reference values of ON or OFF indicating whether it is stabilized or not, and if said value is selected as ON, the exposure time reference value is computed in a manner to allow the exposure time to be a predetermined time or less.
Claim 6
Dependent Claim 27 words
The image pickup device claimed in claim 2, wherein the computing means (12) serves to compute the stabilization reference value based on the exposure time reference value.
Claim 7
Dependent Claim 27 words
The image pickup device claimed in claim 2 wherein the computing means (12) serves to compute the exposure time reference value based on the stabilization reference value.
Claim 8
Dependent Claim 28 words
The image pickup device claimed in claim 2 wherein the computing means (2) employs a fluctuating amount of an image output by said stabilizing means (11) for computation.
