    摘要： A photoelectric conversion device includes a photoelectric conversion unit, a light value holding unit that holds light values based on signal charges generated during a first exposure period and a second exposure period having at least one of start timing and end timing different from that of the first exposure period, a comparison unit that compares the light value based on the signal charge generated during the first exposure period with the light value based on the signal charge generated during the second exposure period, and a control unit that sets a third exposure period and a fourth exposure period having at least one of the start timing and end timing different from that of the third exposure period on the basis of a comparison result of the comparison unit. The third and fourth exposure periods are less than at least one of the first and second exposure periods.

    摘要： The present technology relates to an image processing device, an image processing method, and a program capable of generating a moving image with a high frame rate. Included are a frame-based first imaging element; an event-based second imaging element; and a generation unit that generates an interpolation frame by using frame data from the first imaging element and event data from the second imaging element. The generation unit generates the interpolation frame by adding, to the interpolation frame, integrated event data obtained by integrating the event data generated within a predetermined period of time. The present technology can be applied, for example, to an image processing device that includes a frame-based imaging element and an event-based imaging element.

    摘要： A photoelectric conversion device including pixels, a scanning circuit and a controller is provided. The scanning circuit performs a driving operation including a first scan of causing the pixels to start an accumulation operation and a second scan of reading out signals from the pixels. The second scan includes first and second driving operations that are different in a length of a readout period. The controller is configured to supply, to the scanning circuit, a first synchronization signal for controlling the first scan and a second synchronization signal for controlling the second scan. A relationship between a cycle of the first synchronization signal and the second synchronization signal in the first driving operation and a cycle of the first synchronization signal and the second synchronization signal in the second driving operation is a non-integer multiple or a non-integral submultiple.

    摘要： Surface pressure measurements on rotating models are important for flow phenomenon identification, understanding flow mechanisms and model aerodynamic design. The disclosure discloses a periodic pressure field measurement system based on the superposed lifetime of pressure sensitive paint, including pressure sensitive paint, a pulse light source, a camera, a synchronizer and a computer. A lifetime superposition method is disclosed in the disclosure for measuring periodic pressure fields of pressure sensitive paint. The disclosure has the beneficial effects: the disclosure acquires, on the basis of a relationship between the fluorescence lifetime of the pressure sensitive paint and the pressure, fluorescence image pair sequence of the pressure sensitive paint with a high signal to noise ratio under a high-frequency pulsating pressure through the strobe light source and the low-frame-rate CCD camera, and obtains the global dynamic pressure distribution according to the measurement principle of the lifetime method, which can effectively reduce system errors.
