In one implementation, a method includes obtaining an image. The method includes correcting color aberration of the image comprising, for a particular pixel of the image by determining one or more chromatic characteristic values for the particular pixel, determining a likelihood that the particular pixel exhibits color aberration based on the one or more chromatic characteristic values for the particular pixel, generating a filtered version of the particular pixel by filtering the particular pixel using pixels in a neighborhood surrounding the particular pixel, and generating a color-corrected version of the particular pixel based on the likelihood that the particular pixel exhibits color aberration and the filtered version of the particular pixel.

According to one embodiment, a learning method includes acquiring first and second images and causing a statistical model to learn based on a first distance output from the statistical model by inputting a first region of the first image, and a second distance output from the statistical model by inputting a second region of the second image. A relationship in size between a third distance to a subject in the first image and a fourth distance to the subject included in the second image is already known. The causing includes causing the statistical model to learn such that a relationship in size between the first and the second distances is equal to a relationship in size between the third and the fourth distances.

An image processing apparatus comprises a communication unit configured to communicate with an external apparatus, an image processing unit configured to perform first image processing on first image data, and a control unit configured to transmit a request for executing second image processing which is different from the first image processing on the first image data to the external apparatus via the communication unit, and receive second image data on which the second image processing has been executed from the external apparatus via the communication unit. In response that a function of the second image processing executable in the external apparatus is updated, the control unit determines whether to transmit a request again for executing the second image processing to the external apparatus.

Provided is a signal processing apparatus that estimates image distortion in a case where images are captured through a transmissive body allowing light to pass through. The signal processing apparatus includes a lens distortion estimation section that estimates lens distortion based on a location of a feature point in a first image and a second image of an object. The first image is captured by an imaging section through a transmissive body and a lens that allow light to pass through. The second image is free of transmissive body distortion caused by the transmissive body and free of the lens distortion caused by the lens. The apparatus further includes a transmissive body distortion estimation section that estimates the transmissive body distortion based on the location of the feature point in the first image and a third image that is obtained by removing the estimated lens distortion from the first image.

Embodiments relate to lateral chromatic aberration (LCA) recovery of raw image data generated by image sensors. A chromatic aberration recovery circuit performs chromatic aberration recovery on the raw image data to correct the resulting LCA in the full color images using pre-calculated offset values of a subset of colors of pixels.

An image sensor includes an optical system including a liquid lens, a nonvolatile memory that stores property information about an amount of change in a refractive power of the liquid lens in response to an application voltage, a temperature sensor that detects a temperature of the liquid lens, and a body module. The optical system, the nonvolatile memory, and the temperature sensor are disconnectable from the body module that includes a controller that performs image processing on image data received from a imaging device and performs liquid lens control for determining the application voltage to be applied to the liquid lens based on the property information stored in the nonvolatile memory, the temperature of the liquid lens detected by the temperature sensor, and a target value for the refractive power of the liquid lens and applying the application voltage to the liquid lens.
