    摘要： An image capturing apparatus includes: plural pixels arranged in matrix, each outputting a signal from a photoelectric conversion element; and plural readout circuits each provided for a corresponding column of the pixels, signals from the pixels being input to the readout circuits. The readout circuit includes an amplifier unit configured to amplify the signal from the pixel, and have a variable gain, and a hold capacitance connected to an output terminal of the amplifier unit via a sampling switch, and having a variable capacitance value. When the variable gain of the amplifier unit is set to be a first gain, the variable capacitance value of the hold capacitance is set to be a first capacitance value. When the variable gain is set to be a second gain larger than the first gain, the variable capacitance value is set to be a second capacitance value smaller than the first capacitance value.

    摘要： An imaging apparatus and a method of driving the same that can generate a digital data of a high resolution pixel signal are provided. The imaging apparatus includes: a pixel (10-1) for generating a signal by photoelectric conversion; a comparing circuit (30-1) for comparing a signal based on the pixel with a time-dependent reference signal; a counter circuit (40-1) performing a counting operating until an inversion of a magnitude relation between the signal based on the pixel and the time-dependent reference signal; and a selecting circuit (30-2) for setting a time-dependent change rate of the reference signal, according to a signal level of the signal based on the pixel.

    摘要： An imaging device whose dynamic range can be wide with a simple structure is provided. In a circuit configuration and an operation method of the imaging device, whether a charge detection portion provided in a pixel is saturated with electrons is determined and an operation mode is changed depending on the determination result. First imaging data is captured first, and is read out in the case where the charge detection portion is not saturated with electrons. In the case where the charge detection portion is saturated with electrons, the saturation of the charge detection portion is eliminated and second imaging data is captured and read out.

    摘要： A solid-state imaging device includes: multiple micro lenses, which are disposed in each of a first direction and a second direction orthogonal to the first direction, focus the incident light into the light-receiving surface; with the multiple micro lenses of which the planar shape is a shape including a portion divided by a side extending in the first direction and a side extending in the second direction being disposed arrayed mutually adjacent to each of the first direction and the second direction; and with the multiple micro lenses being formed so that the depth of a groove between micro lenses arrayed in a third direction is deeper than the depth of a groove between micro lenses arrayed in the first direction, and also the curvature of the lens surface in the third direction is higher than the curvature of the lens surface in the first direction.
