Abstract
Disclosed is an image sensing device and an operating method thereof, the image sensing device including an image sensor suitable for generating first image signals, corresponding to some of a plurality of pixels, in a binning mode, and an image processor suitable for generating second image signals, corresponding to other pixels, by performing an interpolation operation based on the first image signals in the binning mode.
Claims19
An image sensing device comprising:
- an image sensor suitable for generating first image signals corresponding to some of a plurality of pixels and not generating second image signals corresponding to other pixels of the plurality of pixels, in a binning mode;
- and
- an image processor suitable for generating the second image signals by performing an interpolation operation based on the first image signals in the binning mode.
An operating method of an image sensing device, comprising:
- entering a binning mode;
- generating first image signals corresponding to some of a plurality of rows in which a plurality of pixels are arranged, by performing an analog binning operation;
- and
- generating second image signals corresponding to other rows, by performing interpolation and digital binning operations based on the first image signals,
- wherein the some of the plurality of rows include a first group of rows and a second group of rows, and
- the other rows include a third group of rows between the first group of rows and the second group of rows.

A method for performing a binning operation in an image sensing device, the method comprising:
- selecting a set number of rows from a plurality of rows in an image matrix with m rows and n columns, wherein m and n are a positive integer;
- selecting a set number of pixels from a plurality of pixels arranged in two or more rows adjacent to each other in the selected rows;
- performing an analog binning operation on pixel signals of the selected pixels to generate analog image signals;
- converting the analog image signals to digital image signals;
- and
- performing an interpolation operation on the digital image signals to generate second image signals corresponding to pixels arranged in remaining rows which are not selected in the selecting of the set number of rows.
