摘要： Electronic devices may be provided with image sensors. Image sensors may be configured to capture images during imaging operations and monitor ambient light levels during non-imaging operations. An image sensor may include image pixels that receive light and dark pixels that are prevented from receiving light. An image sensor may include an ambient light detection circuit. The ambient light detection circuit may include an oscillator, timing and control circuitry, and a counter. The oscillator may be switchably coupled to the image pixels and the dark pixels. The counter may be configured to count up oscillator cycles of the oscillator while the oscillator is coupled to the image pixels and to count down oscillator cycles of the oscillator while the oscillator is coupled to the dark pixels. The counter may provide a count value that depends on a signal from the image pixels and a signal from the dark pixels.

摘要： Multiple-exposure high dynamic range image processing may be performed that filters pixel values that are distorted by blooming from nearby saturated pixels. Pixel values that are near saturated pixels may be identified as pixels that may be affected by blooming. The contributions from those pixels may be minimized when producing a final image. Multiple-exposure images may be linearly combined to produce a final high dynamic range image. Pixel values that may be distorted by blooming may be given less weight in the linear combination.

An arrangement for locating the array driving circuit relative to the reference pixels is also provided.

摘要： An imager including a self test mode. The imager includes a pixel array for providing multiple pixel output signals via multiple columns; and a test switch for (a) receiving a test signal from a test generator and (b) disconnecting a pixel output signal from a column of the pixel array. The test switch provides the test signal to the column of the pixel array. The test signal includes a test voltage that replaces the pixel output signal. The test signal is digitized by an analog-to digital converter (ADC) and provided to a processor. The processor compares the digitized test signal to an expected pixel output signal. The processor also interpolates the output signal from a corresponding pixel using adjacent pixels, when the test switch disconnects the pixel output signal from the column of the pixel array.

摘要： Imagers reproduce an image by converting photons to a signal that is representative of the image. A sensor readout module reads reset and signal voltages corresponding to a plurality of integration times for each of a plurality of pixels. The sensor readout module is capable of determining whether the differences between reset and signal voltages corresponding to respective integration times indicate a saturation condition of the pixel. Accordingly, the sensor readout module may provide an output signal based on reset and signal voltages corresponding to an integration time that is less than an integration time for reset and signal voltages that indicate the saturation condition. A normalization module may normalize the output signal to correspond with a linear response curve.
