    Abstract: An image-capturing device includes an image-capturing section, an image-data-generation section, a display section, and a timing generator. The image-capturing section is configured and arranged to capture an image of a subject at a timing on the basis of a vertical synchronization signal inputted and generate image-capture data corresponding to a frame. The image-data-generation section is configured and arranged to generate image data on the basis of the image-capture data corresponding to the frame. The display section is configured and arranged to display the image data. The timing generator is configured and arranged to output the vertical synchronization signal. The timing generator outputs the vertical synchronization signal at a variable timing in accordance with a generating condition of the image data corresponding to the frame. The image-capturing section generates the image-capture data corresponding to another frame at the timing on the basis of the vertical synchronization signal.

    Abstract: An imaging display apparatus includes an imaging unit that images a subject at a first frame rate and outputs an imaging signal, an image processing portion that generates an image signal based on the imaging signal, a VRAM that stores the image signal, and a display unit that performs displaying based on the image signal at a second frame rate which is equal to or greater than N (N is a natural number equal to or greater than 2) times the first frame rate. The VRAM stores the image signals for one frame to be displayed by the display unit. The display unit performs displaying N times based on the image signals for one frame.

    Abstract: An image capturing device includes an image capturing unit capturing an image at a timing based on a first frame rate and outputs data corresponding to the image after a first period, an image data generation unit generating image data based on the output data and outputting the image data after a second period, a display unit displaying a display image based on the image data after the second period and at a timing based on a second frame rate, and a mode selecting unit selecting a first or second mode. The first mode prioritizes reduction in a display delay time. The second mode prioritizes image quality of the display image over reduction in the display delay time. A total period of the first and second periods is less than or equal to a first vertical synchronization period based on the first frame rate when the first mode is selected.

    Abstract: An image capturing device includes an image capturing unit, an image data generation unit, and a display unit. The image capturing unit captures an image at a timing based on a first frame rate of the image capturing unit and outputs output data after a first period. The image data generation unit generates and outputs the image data after a lapse of a second period after the first period. The display unit displays a display image after the second period and at a timing based on a second frame rate of the display unit. The first period corresponds to an exposure time of the image capturing unit, and the second period corresponds to a processing time of the image data generation unit. A total period of the first period and the second period is less than or equal to a vertical synchronization period based on the second frame rate.

    Abstract translation: 图像捕获装置包括图像捕获单元，图像数据生成单元和显示单元。 图像拍摄单元基于图像拍摄单元的第一帧率在定时捕获图像，并且在第一周期之后输出输出数据。 图像数据生成单元在经过第一时段之后的第二周期之后生成并输出图像数据。 显示单元在第二时段之后和基于显示单元的第二帧速率的定时显示显示图像。 第一周期对应于图像拍摄单元的曝光时间，第二周期对应于图像数据生成单元的处理时间。 基于第二帧率，第一周期和第二周期的总周期小于或等于垂直同步周期。
