An image sensor including an image signal processor and an operating method of the image sensor are provided. An image sensor may include a pixel array configured to convert a received optical signal into electrical signals, a readout circuit configured to analog-digital convert the electrical signals to generate image data, and an image signal processor configured to perform one-dimensional filtering in each of a first direction and a second direction on the image data to remove noise of the image data, the second direction being different than the first direction.

Image sensor including image signal processor and operating method of the image sensor

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.

Apparatus for evaluating camera module and operating method thereof

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.

Image signal processor for performing auto zoom and auto focus, image processing method thereof, and image processing system including the image signal processor

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 nunit 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 nunit areas.
