Abstract: The present technology relates to a signal processing device, an imaging device, and a signal processing method which are capable of recognizing a blinking target object reliably and recognizing an obstacle accurately, in a situation in which a luminance difference is very large. Signals of a plurality of images captured at different exposure times are added using different saturation signal amounts, and signals of a plurality of images obtained as a result of the addition are synthesized, and thus it is possible to recognize a blinking target object reliably and recognize an obstacle accurately, in a situation in which a luminance difference is very large. The present technology can be applied to, for example, a camera unit or the like that captures an image.

Abstract: The present technology improves the image quality of a synthesized image in a device that synthesizes a plurality of images. Disclosed is an image processing device that includes a detection section, a synthesis ratio generation section, and a synthesis section. The detection section detects whether a light source has blinked during an exposure period of a detection target image among a plurality of images captured in chronological order, and outputs a detection result. In a case where the detection result indicates that the light source has blinked, the synthesis ratio generation section generates a synthesis ratio for making the percentage of the detection target image lower than the percentage of an image other than the detection target images. The synthesis section synthesizes the plurality of images at the synthesis ratio.

Abstract: The present technology relates to an image capture device, a method of image capture, a signal processing device, a method of signal processing, and a program capable of capturing reliably a blinking image capture target.

The present technology is applicable to, in one example, a camera unit or the like used to capture an image.

In an image processing apparatus including an input unit and an estimation unit, a mixed image signal is input to the input unit, the mixed image signal being obtained by mixing a plurality of image signals with different exposure times that have been generated by an image sensor, on a basis of a predetermined mix ratio. The estimation unit is configured to estimate a mixed image signal noise being a noise of the mixed image signal, on a basis of the mix ratio, a noise characteristic coefficient indicating a noise characteristic of the image sensor, and a ratio between the exposure times in the plurality of image signals.

Abstract: A server of a content output system acquires a user parameter registration information including a user name of a display and a title of a request content. When an image-quality and sound-quality optimum parameter is included, the server acquires the image-quality and sound-quality optimum parameter as a user's user setting information. When the server cannot acquire the user's user setting information, the server retrieves a user parameter registration information including a user name of another person and the title of the request content.
