Image sensor unit and imaging apparatus

An image sensor unit comprising:

• a microlens array including a plurality of microlenses arranged in a two-dimensional array;
• and
• a sensor, including a plurality of pixels arranged in a two-dimensional array, and configured to receive light through the microlens array,
• wherein the sensor includes a plurality of sensor regions that are arranged in a two-dimensional array and respectively include pixels having different light sensitivities arranged in a matrix arrangement,
• wherein the pixels at corresponding positions of the plurality of sensor regions have identical light sensitivities, and
• wherein each of the microlenses of the microlens array is arranged to direct the light to a corresponding one of the plurality of sensor regions of the sensor,
• the pixels in a first row or column of the matrix arrangement of each of the plurality of sensor regions have a first light sensitivity,
• the pixels in a second row or column of the matrix arrangement of each of the plurality of sensor regions have a second light sensitivity different from the first light sensitivity,
• the first and second light sensitivities are different from the light sensitivities of the pixels in rows or columns of the matrix arrangement other than the first and second rows or columns of the matrix arrangement of each of the plurality of sensor regions.
