A fingerprint recognition device is provided. The fingerprint recognition device includes an image acquisition module acquiring a fingerprint image including an input fingerprint, a preprocessing module generating a preprocessed image by preprocessing the fingerprint image, a minutiae extraction module extracting coordinates of each of minutiae and orientation points of the input fingerprint from the preprocessed image and a fake detection module receiving regions-of-interest (ROIs), including the coordinates of each of the minutiae or orientation points of the input fingerprint, and determining whether the input fingerprint is a fake by performing learning using the received ROIs.

Fingerprint recognition device and smart card

A processing circuitry is configured to generate a first analysis result based on a size of a partial area of a target area when the partial area is captured by only one of a first sensor or a second sensor, based on first image data for the target area captured by the first sensor and second image data for the target area captured by the second sensor, and generate first final image data or second final image data by using the first image data and the second image data, based on the first analysis result. A difference between the first final image data and the second final image data is based on a difference between a first characteristic of the first sensor and a second characteristic of the second sensor.

Processing circuit analyzing image data and generating final image data

An image processing system may include a first image sensor, a second image sensor, and an image processing device. The image processing device may be configured to obtain a first image and a second image by respectively processing the first image data and the second image data. The image processing device may output an image based on the first image when a zoom factor of the output image is lower than a first reference value, generate a correction image by correcting locations of second reference coordinates of the second image based on first reference coordinates of the first image when the zoom factor of the output image is between the first reference value and the second reference value, and may output an image based on the second image when the zoom factor exceeds the second reference value.

Image processing systems for correcting processed images using image sensors

An image pickup device includes first and second cameras, and first and second image signal processors (ISP). The first camera obtains a first image of an object. The second camera obtains a second image of the object. The first ISP performs a first auto focusing (AF), a first auto white balancing (AWB) and a first auto exposing (AE) for the first camera based on a first region-of-interest (ROI) in the first image, and obtains a first distance between the object and the first camera based on a result of the first AF. The second ISP calculates first disparity information associated with the first and second images based on the first distance, moves a second ROI in the second image based on the first disparity information, and performs a second AF, a second AWB and a second AE for the second camera based on the moved second ROI.
