A solid state image sensor includes light receiving sections formed in a two-dimensional array, in which the light receiving section in one unit is formed such that a lens provided on a light receiving surface, a first light receiving element configured to receive light incident from an object via the lens, and a second light receiving element provided in a layer below the first light receiving element and configured to receive light incident from the object via the lens and the first light receiving element and acquire information about a distance to the object configure a stacked structure.

Solid state imaging sensor, observation apparatus using solid state image sensor, method for driving image pickup section, and recording medium for recording program for driving image pickup section

An observation apparatus includes an imaging unit, a driving mechanism and a control unit. The imaging unit takes images of a target object. The driving mechanism moves the imaging unit to change an observation position of the target object. The control unit controls the driving mechanism and the imaging unit while switching between a first mode in which the imaging unit takes images while simultaneously being moved at a high speed by the driving mechanism, and a second mode in which the imaging unit takes images having a higher resolution than the images taken in the first mode while simultaneously being moved at a speed lower than that of the first mode.

Observation apparatus, measurement system and observation method

An imaging device of the present invention comprises a first combination processing circuit that carries out first cumulative combination processing for every pixel of image data that has been generated by the image sensor and image data that has been stored in a memory, and updates pixel data, a second combination processing circuit that carries out second cumulative combination processing for every pixel of image data that has been generated by the image sensor and image data that has been stored in the memory, and updates pixel data, and a controller that determines whether or not level of each pixel data constituting image data is a given threshold level or greater, and in accordance with the result of determination selects to either carry out the first cumulative processing by the first combination processing circuit, or to carry out the second cumulative processing by the second combination processing circuit.

Imaging device and imaging method

An imaging device of the present invention comprises an image sensor having a plurality of pixels made up of a first pixel group and a second pixel group, a flicker detection section for detecting bright states and dark states of all taken images based on a periodic flicker action of a light source contained in a subject from image output from the second pixel group, and a flicker correction calculation sectionfor, when light of brightness having bright states and dark states due to periodic flicker is incident, correcting brightness output gain corresponding to all pixels of the plurality of pixels corresponding to the first pixel group so that brightness output of taking images from the first pixel group becomes a standard brightness output.
