Imaging apparatus and imaging method, camera module, and electronic apparatus capable of detecting a failure in a structure in which substrates are stacked
The present disclosure relates to an imaging apparatus and an imaging method, a camera module, and an electronic apparatus that are capable of detecting a failure in an imaging device having a structure in which a plurality of substrates are stacked. The timing at which a row drive unit provided in a second substrate outputs a control signal for controlling accumulation and reading of pixel signals in a pixel array provided in a first substrate is compared with the timing at which the control signal output from the row drive unit is detected after passing through the pixel array. Depending on whether or not the timings coincides with each other, a failure is detected. The present disclosure can be applied to an imaging apparatus mounted on a vehicle.

METHOD FOR CORRECTING DEFECTS AND IN PARTICULAR FOR REDUCING NOISE IN AN IMAGE PROVIDED BY AN IMAGE SENSOR
A method of correcting defects appearing in an image produced by an image sensor, the method comprising: receiving an image to be corrected, taken by the image sensor, receiving a temperature from the image sensor, acquired when the image to be corrected is taken by the image sensor, receiving an integration time applied by the image sensor when taking the image to be corrected, and for each pixel of the image to be corrected, subtracting from the pixel value a pixel-specific noise correction factor derived from a noise reduction model comprising a linear component dependent on the temperature of the image sensor, added to an exponential component depending on the temperature of the image sensor and multiplied by the integration time, the linear and exponential components depending on coefficients specific to the pixel.

Infrared imager non-uniformity correction with bad pixel detection and correction
A camera system includes an imager unit for recording image data and converting the image data into a digital image signal, and a video processing unit operatively connected to the imager unit for receiving the digital image signal from the imager unit and for generating a corrected video output signal. The video processing unit has a dead pixel correction unit and a subsequent non-uniform offset error correction unit. The dead pixel correction unit is configured for correcting the signal of confirmed dead pixels, which are referenced in a map of confirmed dead pixels associated to the dead pixel correction unit. The non-uniform offset error correction unit is configured for correcting readout amplifier non-uniformity and pixel level non-uniformity in the digital image signal. The non-uniform offset error correction unit is further configured for new dead pixel detection simultaneously to the pixel level non-uniformity correction.

Medical image processing apparatus and medical observation system
A medical image processing apparatus includes: a defective pixel specifier configured to specify a defective pixel in a captured image based on a pixel level of each pixel in the captured image; a setting unit configured to set a correction degree of a defect correction process of making a brightness of the defective pixel approach a brightness of a discrimination area including surrounding pixels positioned around the defective pixel; and a defect corrector configured to perform the defect correction process according to the correction degree. When a difference between the brightness of the defective pixel and the brightness of the discrimination area is divided into a first range and a second range in which the difference is larger than that in the first range, the setting unit sets a higher correction degree for the difference is in the second range than the first range.
