Abstract
An image sensing device may include: a variable color filter configured to vary the wavelength range of light transmitted thereby; and a pixel array comprising a plurality of unit pixels each configured to generate a pixel signal corresponding to the intensity of light having penetrated the variable color filter.
Claims20
An image sensing device comprising:
- a variable color filter configured to receive incident light on the image sensing device and operable to vary a wavelength range of light transmitted thereby;
- and
- a pixel array located to receive a portion of the incident light transmitted from the variable color filter and comprising a plurality of unit pixels, each unit pixel configured to [SK(1] generate a pixel signal corresponding to an intensity of light having transmitted through the variable color filter.
An image sensing device comprising:
- a substrate including a pixel array including a plurality of unit pixels;
- a variable color filter disposed over the substrate and configured to receive a filter control signal, and vary a wavelength range of light transmitted by the variable color filter in response to the filter control signal;
- and
- a filter driver coupled to the variable color filter and configured to generate the filter control signal for controlling the variable color filter, and apply the filter control signal to the variable color filter.
