    摘要： Provided is a highly sensitive sensor system that can improve the S/N ratio by use of an electronic circuit without complicating the sensor body or degrading temporal resolution. A broad spectrum sensor element outputs an electric signal corresponding to a detected physical quantity, the sensor driven by multiplying a carrier signal by m-sequence code. The spread spectrum signal, after phase adjustment, is used to demodulate the sensor output signal, which corresponds to the broad spread spectrum of the physical quantity. The electrical noise generated in the sensor is a broad spread spectrum and is suppressed by low-pass filtering so as to improve the S/N ratio.

    摘要： An image processing apparatus comprises: an acquisition unit that divides an inputted video image into a plurality of divisions, and acquires a histogram of each of the divisions; a generation unit that generates a gradation conversion curve for each of the divisions; a determination unit that determines whether or not the inputted video image is a multi-screen video image; and a gradation correction unit that performs a smoothing process in accordance with a pixel position, to correct the gradation of the video image in each of the divisions using the gradation conversion curve of each of the divisions, wherein when the inputted video image is the multi-screen video image, the determination unit detects a position of a boundary between the plurality of video image contents, and the gradation correction unit does not perform the smoothing process within a predefined area from the boundary.
