Abstract
Abstract An image pickup device is provided which includes an image pickup unit, a fluctuation stabilizer, an exposure time controller, and a computing unit. The image pickup unit sends a video signal to the fluctuation stabilizer in which unnecessary fluctuations of the image output by the image pickup unit are stabilized depending on a stabilization reference value. The exposure time controller serves to control an exposure time used for the image pickup unit depending on the exposure time reference value. The computing unit functions to compute the stabilization reference value and the exposure time reference value. Such image pickup device produces an improved visually natural image.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
65 words
An image pickup device comprising image pickup means, stabilizing means for stabilizing an unnecessary vibration of an image output by said image pickup means according to a stabilization reference value, control means for controlling an exposure time used for said image pickup means according to an exposure time reference value, and computing means for computing said stabilization reference value and said exposure time reference value.
Claim 2
Dependent Claim
65 words
An image pickup device comprising image pickup means, stabilizing means for stabilizing an unnecessary vibration of an image output by said image pickup means according to a stabilization reference value, control means for controlling an exposure time used for said image pickup means according to an exposure time reference value, and computing means for computing said stabilization reference value and said exposure time reference value.
Claim 3
Dependent Claim
68 words
The image pickup device claimed in claim 1, wherein said stabilization reference value includes two states of ON and OFF, said ON state indicating that the fluctuation stabilization is executed and the OFF state indicating that the fluctuation stabilization is suspended, and when said ON state is selected, said computing means computes the exposure time reference value such that the exposure time is less than a predetermined time.
Claim 4
Dependent Claim
24 words
The image pickup device claimed in claim 1, wherein the computing means computes the stabilization reference value based on the exposure time reference value.
Claim 5
Dependent Claim
24 words
The image pickup device claimed in claim 1 wherein the computing means computes the exposure time reference value based on the stabilization reference value.
Claim 6
Dependent Claim
41 words
The image pickup device claimed in claim 1 wherein the computing means employs a fluctuating amount of an image output by said stabilizing means for computation of at least one of said stabilization reference value and said exposure time reference value.
