摘要： An image signal processor may be configured to process an image based on simultaneously performing auto zoom and auto focus. An image signal processor may be configured to receive a first image from an image sensor may include processing circuitry configured to determine auto focus information on an object in the first image using a depth map, set a first area based on calculating a first outer point and a second outer point associated with the object using the depth map, set a second area based on a particular ratio that is determined based on the first outer point and the second outer point, and determine auto zoom information based on calculating a zoom ratio corresponding to a size of the second area.

摘要： Methods of adjusting an image sensor may be provided. A test image of a test chart including an evaluation area may be obtained using the image sensor. The evaluation area may have a shape of a circle, wherein the evaluation area includes first through nth unit areas arranged in a rotational direction around the circle, and wherein each of the first through nth unit areas has a different level of brightness. A signal-to-noise ratio (SNR) may be calculated for each of the first through nth unit areas based on the test image of the test chart. A setting of the image sensor may be adjusted based on calculating the signal-to-noise ratio for each of the first through nth unit areas.

摘要： A camera module evaluating apparatus includes a mobile device including a camera module, a transparent display device configured to display an object, a chart positioned farther from the mobile device than the transparent display device and configured to display a long-distance object, and a test device configured to perform an autofocusing (AF) test operation on the camera module when the camera module captures an image of the object.
