  • Publication number: 20240107200
    Abstract: A solid-state imaging device includes a pixel array that is quadrilateral and includes pixels arranged in rows and columns, where each of the pixels accumulates an electric charge resulting from photoelectric conversion. The pixel array includes: a first area including first pixels for obtaining a captured image; and a second area including a second pixel for individually identifying the solid-state imaging device. The second area is provided in the vicinity of at least one corner among four corners of the pixel array, where the vicinity is a range of a predetermined number of pixels away from the at least one corner. The second pixel includes circuit elements or optical elements different from circuit elements or optical elements in each of the first pixels.

  • Publication number: 20170364107
    Abstract: In the related art, there is a problem that the condition of a load is monitored in an indirect manner so that an efficiency enhancing effect is not obtained. A switching regulator control circuit includes an oscillator for generating a carrier signal and a transistor drive circuit for driving a switching transistor and a synchronous rectification transistor based on a PWM signal generated based on the carrier signal. The oscillator switches the frequency of the carrier signal based on the direction of a source-drain voltage of the synchronous rectification transistor.
