摘要： A control apparatus (121) includes a generation unit (121a) for generating first and second focus detection signals based on a plurality of types of color signals from first and second pixel groups that receive light beams passing through partial pupil regions different from each other, and a calculation unit (121b) for calculating a defocus amount by a phase difference detection method by using the first and second focus detection signals, and the generation unit combines the color signals with respect to the first pixel group so that centroids of the color signals in a pupil division direction coincide with each other to generate the first focus detection signal, and combines the color signals with respect to the second pixel group so that centroids of the color signals in the pupil division direction coincide with each other to generate the second focus detection signal.

摘要： A range finding apparatus uses a light-receiving device in which a first pixel having a first sensitivity and a second pixel having a second sensitivity that is lower than the first sensitivity are two-dimensionally arranged. The range finding apparatus measures time periods from a predetermined time until times when light is incident on each of the first pixel and the second pixel, and computes distance information for the first pixel and the second pixel based on the measured time periods. The measurement resolution used to measure the time period for the second pixel is lower than a measurement resolution used to measure the time period for the first pixel.

摘要： Disclosed in a range finding apparatus that can efficiently perform range finding that uses light of different wavelengths. The range finding apparatus comprises a light source device capable of concurrently emitting light of a first wavelength and light of a second wavelength that is longer than the first wavelength and computes distance information based on a time period from when range finding is started until when incident of light on a pixel of a light receiving part is detected. In a pixel array of the light receiving part, a first pixel configured to receive light of the first wavelength and a second pixel configured to receive light of the second wavelength are two-dimensionally arranged.

摘要： An image sensor comprises a plurality of pixels, and signals are read out in units of rows. The plurality of pixels comprise a plurality of microlenses, and for each microlense, a pair of first semiconductor regions formed at a first depth; a pair of second semiconductor regions formed at a second depth deeper than the first depth; and a plurality of connecting regions that connect the first semiconductor regions and the second semiconductor regions, respectively. Pixels having a first arrangement have the first and second semiconductor regions arranged in a row direction, pixels having a second arrangement have the first semiconductor regions arranged in a column direction and the second semiconductor regions arranged in the row direction. A crosstalk ratio between the first semiconductor regions in the second arrangement is made smaller than that in the first arrangement.

摘要： Disclosed is a light-projection device that is used for a range finding apparatus that computes a distance to an object that has reflected light, by measuring a time difference between a time when light is emitted and a time when reflected light is detected. The light-projection device comprises a light source array in which a plurality of light-emitting elements are two-dimensionally arranged and a light-projection lens that adjusts a light projection range of light emitted from the light source array. The light projection device further comprises a driving device that changes relative positions between the light source array and the light-projection lens and a light source control unit that switches on the light source array under conditions where the light source array is in different positions.

摘要： Disclosed is a light-receiving device having a wide dynamic range. The light receiving device comprises a pixel array in which a first pixel provided with a first optical band pass filter and having a first sensitivity and a second pixel provided with a second optical band pass filter and having a second sensitivity that is lower than the first sensitivity are two-dimensionally arranged. A full width at half maximum of the second optical band pass filter is narrower than a full width at half maximum of the first optical band pass filter.
