Disclosed are a camera system with a complementary Pixlet structure and an operation method thereof. According to an embodiment, the camera system comprises: an image sensor including at least one 2*2 pixel block composed of a first pixel, a second pixel and two third pixels, wherein each of the two third pixels includes a deflected small Pixlet that is arranged at a position diagonal to each other in a 2*2 pixel block and is deflected in opposite directions to be symmetric with respect to each pixel center and a large Pixlet disposed to be adjacent to the deflected small Pixlet and the Pixlet includes a photo diode for converting an optical signal into an electrical signal; and a distance calculation part that receives images acquired from a deflected small Pixlet of each of the two third pixels and calculates a distance between the image sensor and a subject by using a parallax between the images.
Description
technical field [0001] The following description relates to an imaging system, and in more detail, describes an imaging system including an image sensor having a complementary Pixlet structure. Background technique [0002] Existing image pickup systems including an image sensor in which only one photodiode is arranged in one pixel under a microlens cannot perform calculations up to Other application functions such as the distance (Depth) to the subject. [0003] Therefore, if the above-mentioned application function is to be implemented in the existing camera system, there is the following disadvantage, that is, it needs to be used in the mode of setting more than two cameras in the camera system or needs to be used in a camera system including a single camera. Set other apertures than normal apertures. [0004] Therefore, various embodiments described below propose a technology that can be formed by providing two photodiodes formed in one pixel (hereinafter, as structura...
