  • Patent number: 12008834
    Abstract: An ultrasonic sensor device includes a plurality of pixels each including an ultrasonic transducer, and a control circuit configured to control the plurality of pixels. Each of the plurality of pixels is configured to hold a signal received by the ultrasonic transducer therein and send the signal to the control circuit as a response signal. The control circuit is configured to acquire an excitation response signal, which is a response signal sent from a pixel after the ultrasonic transducer therein is excited, acquire a non-excitation response signal, which is a response signal sent from a pixel when the ultrasonic transducer therein is not excited, and correct the excitation response signal based on the non-excitation response signal.

  • Patent number: 11971676
    Abstract: A processor derives a plurality of unit density values which are each an average value of sensed densities for each of a plurality of unit areas sectioned for each unit length in a test toner image. The processor derives a weighted average of the plurality of unit density values to derive a test image density used for adjusting a control parameter in a printing portion. The unit length is a greatest common factor of two target lengths corresponding to perimeters of two types of target rotating members out of the plurality of rotating members. When a number of the plurality of unit areas is represented by n, n is a value obtained by subtracting 1 from an added value of a first constant and a second constant. The first constant and the second constant are values obtained by respectively dividing the two target lengths by the unit length.

  • Patent number: 11587240
    Abstract: In tracking of a moving body using image data in detecting a target moving body having few externally outstanding features, such as coloring and a shape, from an image in an image frame, if an image of the target moving body overlaps a background image largely and their colorings are the same or similar to one another, it is difficult to detect the target moving body. A template image of the target moving body is superimposed on a background image of a region (periphery) of a candidate position of the target to generate a composite image and the moving body is detected based on a degree of match calculated through comparison of the composite image with an image of the region (periphery) of the candidate position of the target.
