Abstract
An image sensing device with a wide dynamic range by using an optical limiter, and an image pickup apparatus using the same. The image sensing device includes an optical limiter for converting an input image into a non-linear image at an intensity greater than a threshold intensity, and an image sensor for converting the non-linear input image into an electrical signal. By forming the optical limiter capable of outputting a non-linear image with respect to the intensity of light on the image pickup surface of the image sensor, the dynamic range of the image sensing device can be expanded without using a separate device.
Claims17
An image sensing device, comprising:
- an optical limiter that converts an input image into a non-linear image at an intensity greater than a threshold intensity;
- and
- an image sensor that converts the non-linear input image into an electrical signal.
An image pickup apparatus using an image sensing device, the apparatus comprising:
- an optical limiter that converts and outputs an input image into a non-linear image at an intensity greater than a threshold intensity;
- an image sensor that photoelectrically converts the image output by the optical limiter;
- a converter that converts and outputs the image from the image sensor into a digital signal;
- and
- a signal processor that performs signal processing to display the input image output by the converter.
An image sensing device comprising:
- means for converting an input image into a non-linear image at an intensity greater than a threshold intensity;
- and
- means for converting the non-linear input image into an electrical signal.
