  • Publication number: 20210281732
    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.

  • Patent number: 11082626
    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.

  • Patent number: 10999520
    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. A predetermined image capture timing of an image capture unit is controlled so that image capture is performed N times during an exposure time in which at least a part of a turn-on period in which an image capture target is on overlaps with an exposure time of image capture of at least one time at a timing of dividing a blinking cycle in which the image capture target to be captured by the image capture unit configured to perform image capture at the image capture timing blinks into N equal parts where N represents more than one. The present technology is applicable to, in one example, a camera unit or the like used to capture an image.

  • Publication number: 20100082137
    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.

  • Publication number: 20070109317
    Abstract: When a YUV signal is inputted to a signal processing circuit from the outside, a histogram detection unit detects a histogram of a single frame of the Y signal, a correlation determination unit determines a correlation between a gain and a level of an inputted Y signal on the basis of the histogram, and a YUV gain determination unit determines the gain. A Y gain multiplication unit and a UV gain multiplication unit multiply each of the inputted Y signal, U signal, and V signal by the same gain to correct the YUV signal. A YUV/RGB conversion unit converts the signal into an RGB signal, and outputs the result to a display element. In the display device, there is no change in color balance even when contrast correction and other nonlinear signal processing are performed.
