  • Patent number: 11134211
    Abstract: In image processing apparatus, a sample hold unit samples and holds an output signal of the image sensor. A timing signal generating circuit generates a sampling clock to specify a sampling timing of the sample hold unit. A controller sets a phase of the sampling clock to the timing signal generating circuit. In an adjustment process that adjusts the phase of the sampling clock, the controller (a) causes the image sensor to scan a reference board, (b) sets predetermined plural phases to the timing signal generating circuit in turn, (c) calculates average values of image data obtained correspondingly to the plural phases and calculates a value of a parameter that indicates a fluctuation width of the average values, and (d) sets the phase of the sampling clock as a phase corresponding to the smallest value of the parameter.

  • Patent number: 8953075
    Abstract: An active pixel CMOS image sensor implements full frame digital correlated double sampling (CDS) with global shutter where all the pixels in the image sensor are reset at substantially the same time and all the pixels in the image sensor integrate incident light at substantially the same time and for substantially the same time duration and correlated double sampling cancellation is performed in the digital domain. In one embodiment, the image sensing device includes an array of light sensing elements, a timing and control circuit and analog-to-digital converters. The timing and control circuit is operative to reset the light sensing elements in the array and to control the array of light sensing elements to integrate incident light. The pixel reset values are cancelled from the corresponding light dependent pixel values for each of the light sensing elements to generate correlated double sampling (CDS) corrected digital output pixel values.

    Abstract: In an embodiment, a solid-state image sensor comprises: pixels arranged in columns and rows; read signal lines each connected to pixels arranged in a row direction; and output signal lines each connected to pixels arranged in a column direction. The read signal lines are classified into a first type of read signal lines each connected to a group of pixels on which R and B rays are incident, and a second type of read signal lines each connected to a group of pixels on which G rays are incident. Two pixels (R, B) on two adjacent columns are arranged on two opposite sides with respect to the first type of read signal line. Two pixels (Gr, Gb) on two adjacent columns are arranged on two opposite sides with respect to the second type of read signal line.

  • Patent number: 8885058
    Abstract: A system is provided that measures the delay time of a first timing signal transmitted from a control unit to an imager and back to a phase detector. The phase detector also receives a second timing signal that is used as a reference to measure against the received/delayed first timing signal. Based on the phase detection, the system will retard or advance the first timing signal to compensate for the phase shift.

  • Patent number: 8885082
    Abstract: A solid-state image sensor has a plurality of pixel units, each pixel unit including a plurality of pixels, and a charge-voltage converter shared by the plurality of pixels. The sensor includes a structural portion including a plurality of wiring layers, an interlayer insulating film, and light waveguides configured by embedding, in portions of the interlayer insulating film located above the photoelectric converters, a material having a refractive index higher than that of the interlayer insulating film. A dummy pattern is formed in the structural portion to reduce a difference between a sensitivity of a first pixel and that of a second pixel, which is produced by a difference between a structure in a periphery of the light waveguide arranged above the photoelectric converter of the first pixel and that of the second pixel.

  • Patent number: 8830365
    Abstract: A circuit for processing an analog signal having a time sequence of discrete signal levels, each of which lies in a time interval and represents an information-bearing segment of the interval while the rest of the time interval is a non-information-bearing segment, comprises a transistor in emitter-follower or source-follower configuration, a high emitter or source resistance or, instead, a high-ohm constant current source, and a device for applying a voltage supply, as well as a switch which is connected between the emitter and a reference potential to prevent a current from flowing via the high-ohm resistance or the high-ohm voltage source for charge reversal of an output capacitance of the circuit in one direction, whereas for charge reversal in the other direction the dynamic current boosting effect of the transistor is exploited. This results in a fast emitter-follower or source-follower circuit which is particularly suitable as the output stage for image sensors.
