Problems solved by technology
Using IR structured light, the problem is that it is difficult to obtain the desired level of depth resolution for moving objects
[0006] However, in the case of the current ToF method, there is a problem that the information that can be obtained from one frame is insufficient, i.e. its resolution is very low
However, in this case, there is a problem in that the size and manufacturing cost of the camera module are significantly increased

An image sensor according to an embodiment of the present invention includes: a pixel array in which a plurality of pixels are arrayed in a grid shape, and which converts reflection light signals reflected from an object into electrical signals; an image processor which converts the electrical signals to generate subframes, and extracts pieces of second depth information having a higher resolutionthan pieces of first depth information extracted from a plurality of the subframes; and a memory for storing the pieces of first depth information, wherein the reflection light signals are input to the pixel array through mutually different optical paths shifted in sub-pixel units of the pixel array, and the memory stores a plurality of the pieces of first depth information that correspond to themutually different optical paths.
Description
technical field [0001] The present invention relates to an image sensor and a camera module using the same. Background technique [0002] In addition to the field of games and culture, 3D content is applied to various fields such as education, manufacturing, autonomous driving, etc., and a depth map is necessary to obtain 3D content. A depth map is a map showing spatial distance, and shows viewing angle information of one point relative to another point in a two-dimensional image. [0003] One of the methods to obtain a depth map is to project infrared (IR) structured light onto an object, and interpret the light reflected from the object to extract the depth map. With IR structured light, there is a problem that it is difficult to obtain a desired level of depth resolution for moving objects. [0004] Meanwhile, as a technique to replace the IR structured light method, a time-of-flight (TOF) method is attracting attention. [0005] According to the TOF method, the time-o...
