  • Patent number: 11637955
    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.

  • Patent number: 10715733
    Abstract: An imaging apparatus includes an imaging unit, a storage unit, an image processing unit, an image signal output unit, and a timing control unit. The timing control unit generates a first vertical synchronizing signal for driving the imaging unit and supplies the first vertical synchronizing signal to the imaging unit, and generates a second vertical synchronizing signal which is obtained by delaying the first vertical synchronizing signal at least by a predetermined time which is variable according to contents of the image processing performed and supplies the second vertical synchronizing signal to the display unit. The timing control unit controls the image signal output unit so that the image signal is read from the storage unit by being delayed by a phase difference between the first vertical synchronizing signal and the second vertical synchronizing signal, after outputting of the imaging signal from the imaging unit.

  • Patent number: 10412332
    Abstract: An image-capturing device includes an image sensor outputting image-capture data of a subject for each predetermined unit, a first and second processors, and a display. The first processor receives the image-capture data, carries out a first processing for the image-capture data, and outputs first processing data. The second processor receives the first processing data, carries out a second processing for the first processing data, and outputs second processing data. The first processor starts the first processing after preparation of the image-capture data of the lowest necessary number of the predetermined unit for executing the first processing is finished. The second processor starts the second processing after preparation of the first processing data of the lowest necessary number of a predetermined unit for executing the second processing is finished. The display receives the second processing data and starts to display data of a single line based on the second processing data.
