Abstract
An image sensor for an electronic device can adjust a scan rate of a reset pointer of a frame relative to a scan rate of a readout pointer of a previous frame. As a result, the image sensor can transition between various readout modes without interrupting image output from the image sensor.

1-20. (canceled)
A method of operating an image sensor comprising an array of photosites, the method comprising:
- reading the array of photosites at a first scan rate during a readout time;
- and
- resetting the array of photosites at a second scan rate;
- wherein,
- the resetting commences during, and after a commencement of, the readout time;
- and
- the second scan rate is faster than the first scan rate.

An image sensor, comprising:
- a photosite array;
- and
- a controller configured to,
- read the photosite array at a first scan rate during a readout time;
- and
- reset the photosite array at a second scan rate;
- wherein,
- the reset commences during, and after a commencement of, the readout time;
- and
- the second scan rate is faster than the first scan rate.
