摘要： An image processing method is provided. The method is configured to process the color-block image output by the image sensor. The high-frequency region of the color-block image is determined. A part of the color-block image within the high-frequency region is converted into a first image using a first interpolation algorithm. A part of the color-block image beyond the high-frequency region is converted into a second image using a second interpolation algorithm. The complexity of the second interpolation algorithm is less than that of the first interpolation algorithm. The first image and the second image are merged into a simulation image corresponding to the color-block image. An image processing apparatus and an electronic device are provided.

摘要： A solid-state imaging device in which a signal from a first photoelectric conversion portion of one pixel, signals from the first photoelectric conversion portion and a second photoelectric conversion portion of the one pixel, and a noise signal from the one pixel are converted into a first digital signal, a second digital signal, and a third digital signal, respectively. As signals of pixels in a first pixel row, the first, the second, and the third digital signals are input from a memory unit to output signal lines. As signals of pixels in a second pixel row adjacent to the first pixel row of a pixel unit in the row direction, the second and the third digital signals are input from the memory unit to the output signal lines while the first digital signal is not output.

摘要： A computer implemented method for reconstructing a 3-D volume image using a radiographic imaging system having one or more x-ray sources and a digital detector. A plurality of radiographic images of a subject at various angles are captured in the digital detector. Image data in two or more pixels of the detector that are adjacent to each other in a row direction or a column direction are combined, while pixels adjacent in the other direction are not combined.

摘要： The various implementations described herein include methods, devices, and systems for implementing high dynamic range and automatic exposure functions in a video system. In one aspect, a method is performed at a video camera device and includes, while operating in an HDR mode: (1) capturing video data of a scene, including: (a) capturing a first subset of the video data with a first exposure time; and (b) capturing a second subset of the video data with a second exposure time, lower than the first exposure time; (2) combining video data of the first subset with video data of the second subset to generate an HDR frame; and (3) adjusting a duration of at least one of the first exposure time and the second exposure time based on one or more parameters of the captured video data, thereby altering a ratio of the first exposure time to the second exposure time.

摘要： The deterioration of image quality due to the mixture of light during pixel mixture is prevented. A filter that transmits a green light component is formed on a light receiving surface of a photoelectric conversion element and a filter that transmits a red light component is formed on a light receiving surface of a photoelectric conversion element. Light which is vertically incident on the filter is incident on the corresponding photoelectric conversion element. However, light which is obliquely incident on the filter is mixed with a photoelectric conversion element adjacent to the corresponding photoelectric conversion element. When pixel mixture is performed, mixed pixel data is reduced from the data of a mixed pixel to perform mixture correction.
