Abstract
An image sensor includes a pixel array; a logic circuit configured to convert an image signal generated from the pixel array during a first period into image data; and a memory. The image data may be written in the memory during a second period, of which at least a portion overlaps the first period. The logic circuit may write dummy data in the memory during a third period overlapping the first period and not overlapping the second period.
Claims20
An image sensor, comprising:
- a first substrate;
- a second substrate stacked over the first substrate;
- a pixel array on the second substrate;
- a logic circuit on the first substrate;
- and
- a memory,
- wherein the logic circuit is configured to convert an image signal generated from the pixel array into image data during a first period, and
- wherein the logic circuit is further configured to:
- write dummy data into the memory during a second period, which at least partially overlaps the first period,
- write the image data during a third period, which at least partially overlaps the first period and is subsequent to the second period, and
- read the image data from the memory during a fourth period, which is subsequent to the third period.

An image sensor, comprising:
- a pixel array including active pixels configured to generate a first signal of an image signal based on a light received from an outside, and including optical black pixels configured to generate a second signal of the image signal as the light is blocked;
- a memory;
- and
- a logic circuit configured to:
- convert the first signal to first image data during a first period,
- write first dummy data into the memory during a second period, which at least partially overlaps the first period,
- convert the second signal to second image data during a fourth period, which is after a third period that is subsequent to the first period,
- write the first image data into the memory during a fifth period, which is subsequent to the second period and at least partially overlaps the fourth period,
- write second dummy data into the memory during a sixth period, which is subsequent to the fifth period and overlaps the fourth period, and
- write the second image data into the memory during a seventh period, which is subsequent to the sixth period and at least partially overlaps the fourth period.
