  • Publication number: 20220060682
    Abstract: An imaging device according to an embodiment of the present disclosure includes a pixel array including a plurality of pixels, a scanning control section that controls scanning of the plurality of pixels, and a readout control section that controls reading of the plurality of pixels. The imaging device further includes a first waveform generation part that generates a plurality of control signals for controlling of at least one of the scanning control section or the readout control section, a second waveform generation part that generates a plurality of reference signals, and a failure detection section that detects a failure of the first waveform generation part or the second waveform generation part on a basis of comparison between the plurality of control signals and the plurality of reference signals.

  • Publication number: 20210377462
    Abstract: To obtain imaging device capable of reporting more reliably an occurrence of trouble. The imaging device of the present disclosure includes an imaging sensor configured to generate image data, a diagnosis circuit configured to perform diagnosis processing for the imaging sensor and an output circuit configured to output a flag signal corresponding to a result of the diagnosis processing, wherein the flag signal is set to a ground level signal in response to the result of the diagnosis processing indicating an error.

  • Publication number: 20210297616
    Abstract: The present technology relates to a signal processing device and method, and a program that enable easier and more accurate failure detection. The signal processing device includes: an addition unit that adds test data for failure detection to valid data on which predetermined processing is to be performed, two or more samples processed in parallel in different paths having a same sample value in the test data; and a signal processing unit that performs the predetermined processing on the valid data and the test data that has been added to the valid data by a plurality of the paths. The present technology can be applied to in-car cameras.

  • Publication number: 20210012853
    Abstract: It is aimed to detect an error of an address abnormality in a memory. An address error detection information generating unit generates address error detection information for detecting an error relating to an access address for a memory. A control part stores the address error detection information generated by the address error detection information generating unit in the memory at a time of write access. An error detecting part compares the address error detection information generated by the address error detection information generating unit with the address error detection information stored in the memory to detect an error at a time of read access.
