  • Patent number: 12256597
    Abstract: A novel functional panel that is highly convenient, useful, or reliable is provided. The functional panel includes a base material and a pair of pixels, and the base material covers the pair of pixels and has a light-transmitting property. The pair of pixels includes one pixel and another pixel, and the one pixel includes a light-emitting device and a first microlens. The light-emitting device emits light toward the base material, and the first microlens is interposed between the base material and the light emission and converges light. The first microlens includes a first surface and a second surface; the second surface is closer to the light-emitting device than the first surface is; and the second surface has a smaller radius of curvature than the first surface. The other pixel includes a photoelectric conversion device and a second microlens. The second microlens is interposed between the base material and the photoelectric conversion and converges external light incident from the base material side.

  • Publication number: 20250071439
    Abstract: The present disclosure relates to a signal processing device, a signal processing method, and a program that enable further improvement in image quality. A calculation unit compares a reference signal based on a large-pixel RAW signal of a pixel of interest with a threshold, and calculates a blending ratio for use in blending processing in which a pixel value of a small-pixel RAW signal of the pixel of interest with a pixel value of the large-pixel RAW signal of the pixel of interest. A saturation determination unit compares the pixel value of the large-pixel RAW signal of the pixel of interest with a saturation determination threshold, and outputs a saturation determination value indicating whether or not the large-pixel RAW signal of the pixel of interest is saturated. A selection unit selects, according to the saturation determination value, whether to output the blending ratio as it is or by replacing the blending ratio with 1.
