  2. Defective pixel - Wikipedia

    en.wikipedia.org/wiki/Defective_pixel

    In some cases, a manufacturer sends all screens to sale then replaces the screen if the customer reports the unit as faulty and the defective pixels meet their minimum requirements for return. [1] Some screens come with a leaflet stating how many dead pixels they are allowed to have before the owner can send them back to the manufacturer.

  3. Stuck-at fault - Wikipedia

    en.wikipedia.org/wiki/Stuck-at_fault

    This is because CMOS may experience a failure mode known as a stuck-open fault, which cannot be reliably detected with one test vector and requires that two vectors be applied sequentially. The model also fails to detect bridging faults between adjacent signal lines, occurring in pins that drive bus connections and array structures.

  4. sCMOS - Wikipedia

    en.wikipedia.org/wiki/SCMOS

    The sCMOS sensor's low read noise and larger area provides a low-noise, large field-of-view (FOV) image that enables researchers to scan across a sample and capture high-quality images. [9] [5] Some disadvantages at this time, (2023), with sCMOS cameras versus related technologies are: sCMOS sensors tend be more expensive than traditional CMOS ...

    A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.

    Typical POST screen (AMI BIOS) Summary screen after POST and before booting an operating system (AMI BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [1]

  7. Fixed-pattern noise - Wikipedia

    en.wikipedia.org/wiki/Fixed-pattern_noise

    This problem arises from small differences in the individual responsitivity of the sensor array (including any local postamplification stages) that might be caused by variations in the pixel size, material or interference with the local circuitry. It might be affected by changes in the environment like different temperatures, exposure times, etc.

  9. Display motion blur - Wikipedia

    en.wikipedia.org/wiki/Display_motion_blur

    Display motion blur, also called HDTV blur and LCD motion blur, refers to several visual artifacts (anomalies or unintended effects affecting still or moving images) that are frequently found on modern consumer high-definition television sets and flat-panel displays for computers.
