The present technology relates to an image processing device, an image processing method, and a program that are able to effectively reduce noise. The image processing device according to the present technology includes a feedback rate setting section, a blending section, and a calculation section. The feedback rate setting section sets a feedback rate for pixels in a current line on the basis of a count that is set for pixels in a previous line. The current line and the previous line are among a plurality of lines forming an image. The pixels in the current line are to be subjected to a blending process of blending inputted pixels in the current line and already outputted pixels in the previous line. The blending section blends the pixels in the current line and the pixels in the previous line in accordance with the feedback rate. The calculation section calculates a count that is indicative of the cumulative number of pixels blended with the pixels in the current line by the blending process and is to be set for the pixels in the current line. The present technology is applicable to in-vehicle cameras.

A communication apparatus includes a communication unit configured to communicate with an external apparatus based on Hypertext Transfer Protocol (HTTP), a recording medium configured to record programs corresponding to a plurality of application programming interfaces (APIs), and a control unit configured to control the communication unit to, when a request regarding any of the plurality of APIs is received, execute the program corresponding to the API regarding which the request is received, and return a response including a data set described in a predetermined structure to the request, wherein the control unit is configured to perform control to describe the data set in the same structure in a case where a request using a first HTTP request method regarding a predetermined API among the plurality of APIs is received and in a case where a request using a second HTTP request method regarding the predetermined API is received.

The invention relates to devices intended for reading and recognizing printed or written characters or for recognizing patterns, e.g., fingerprints, for document verification/authentication (e.g., passport verification). A portable hardware-software complex (PHSC) includes a housing with a visible spectrum camera and a fingerprint scanner. The housing includes a power supply unit and a processor. On the housing from the fingerprint scanner side there is a display, and on the back side of the housing there is a visible spectrum camera with two or more sources of visible spectrum radiation and UV radiation, installed to illuminate the visible spectrum camera field of view. On the back side of the body there is an infrared camera and one or more sources of infrared radiation, for illuminating the field of view of the infrared camera.

An image processing apparatus is provided, that is configured to: extract a first pixel value corresponding to a first viewpoint that is one of a plurality of viewpoints to capture a subject image, at a target pixel position from image data having the first pixel value; extract second and third luminance values corresponding to second and third viewpoints that are different from the first viewpoint, at the target pixel position from luminance image data having the second and third luminance values; and calculate at least any of second and third pixel values of the second and third viewpoints such that a relational expression between the second or third pixel value and the first pixel value extracted by the pixel value extracting unit remains correlated with a relational expression defined by the second and third luminance values.

Devices, methods, and non-transitory program storage devices for spatiotemporal image noise reduction are disclosed, comprising: maintaining an accumulated image in memory; and obtaining a first plurality of multispectral images (e.g., RGB-IR images). For each image in the first plurality of multispectral images, the method may: calculate a multispectral guide image for the current image; calculate blending weights for the current image; apply the calculated blending weights to each channel of the current image to generate a denoised current image; and update the accumulated image based on pixel differences between the denoised current image and the accumulated image. In some embodiments, additional images (e.g., the accumulated image and/or other images captured prior to or after a given current image) may also be included in the denoising operations for a given current image. Finally, the method may generate a denoised output image for each input image, based on the updated accumulated image.

Noise is sufficiently reduced in a moving image. A determination section determines, each time an input image is input, whether a change amount of a pixel value distribution in the input image and an output image that is output is smaller than a predetermined threshold value. A mixing ratio supply section supplies a value that becomes larger as the number of times the change amount is sequentially determined to be smaller than the predetermined threshold value becomes larger, the value serving as a mixing ratio of the output image in mixing of the input image and the output image. A mixing section mixes, each time the input image is input, the input image and the output image based on the supplied mixing ratio and outputs the input image and the output image to serve as a new output image.
