Abstract: A camera device includes an image sensor including a pixel array and a logic circuit, with the camera device further comprising an optical module that includes a plurality of lenses arranged in a path of travel of light incident on the image sensor. The pixel array includes a plurality of pixels having a general pixel, a first autofocus pixel and a second autofocus pixel, and at least one of the plurality of lenses has an edge that extends in a first direction. A height of an upper surface of the microlens, included in the first autofocus pixel, is different from a height of an upper surface of the microlens included in the second autofocus pixel.

Abstract: An image apparatus may be configured to calculate a depth of an object relative to the image apparatus. The image apparatus may include an image sensor that may capture a plurality of images of the object. Depth calculation may include calculating a binocular disparity using the plurality of images, measuring a local temperature value from at least one temperature sensor, correcting a focal length of at least a portion of the image apparatus according to the measured local temperature value, and calculating a depth of the object using the binocular disparity and the corrected focal length. The corrected focal length may be determined based on a focal length variation value. The focal length variation value may be determined based on performing contrast autofocus on one or more captured images and the local temperature value.
