Latest Patents

Hoshino's latest patents include an innovative imaging device with extended dynamic range. This device features an imaging element capable of reading accumulated charges at different exposure times within a predetermined frame period. The imaging element is divided into groups for long-time and short-time exposure, allowing for separate adjustments of read timings. This design enables the imaging device to extend its dynamic range based on the contrast between light and shade of a subject.

Another notable patent involves video signal processing for generating a level mixed signal. This imaging device includes an all-pixel readout imaging element that outputs LONG and SHORT signals for each pixel line. A mixing level calculator determines the mixing level at which the luminance level of the LONG signal is saturated. An offset calculator then raises the luminance level of the SHORT signal to this mixing level. This process results in an image with a wide dynamic range and high resolution, while also suppressing line-to-line luminance differences.
