The display area selection circuit selects a desired display area. The signal generating circuit sets a period of each shift signal generated while the selection position of the pixel diode is between the shift start position and the display start position shorter than a period of each shift signal generated while the selection position of the pixel diode is between the display start position and the display end position.

A solid-state imaging device 1 according to an embodiment of the invention includes: pixel units P(x, y) each of which includes a photoelectric conversion element and an amplifying unit for a pixel unit and which are two-dimensionally arranged; at least one row of optical black units Pob(x, y) each of which includes a photoelectric conversion element, an amplifying unit for a pixel unit, and a light shielding film that covers the photoelectric conversion element, the photoelectric conversion element and the amplifying unit for a pixel unit being the same as those of the pixel unit P(x, y); and at least one row of optical gray units Pog(x, y) each of which includes an amplifying unit for a pixel unit which is the same as that of the pixel unit and to which a reference voltage is input. The value of the reference voltage is less than the value of the output signal from the photoelectric conversion element in a saturated state.

An eye movement measurement apparatus 1 measures movement of a cornea 101 by imaging a corneal reflection light image L2 generated as a result of irradiating the cornea 101 with infrared light L1. The eye movement measurement apparatus 1 includes: an imaging section 5 having a sensor section 51 including a plurality of pixels arrayed two-dimensionally, for generating imaging data including the corneal reflection light image L2 made incident on the sensor section 51; a bright spot position operation section 6 that calculates a position of the corneal reflection light image L2 in the imaging data; and a tremor signal operation section 7 that generates a third data string indicating a tremor component included in movement of the cornea 101 by calculating a difference between a first data string concerning temporal changes in position of the corneal reflection light image L2 and a second data string obtained by smoothing the first data string. Accordingly, an eye movement measurement apparatus capable of accurately detecting a tremor component is realized.

There is provided a solid-state imaging device in which images can be read at high speed. Since an n-th processing circuit (e.g. PU1) can be connected to n-th pixel columns (N1) in respective imaging blocks B1, B2, and B3 via switches Q (1), Q (4), and Q (7), signals from the adjacent pixel columns (N2) are to be processed separately by another processing circuit (PU2) even when a partial readout area R may be small. In addition, an image data arithmetic section 10 specifies the partial readout area R restrictively, which allows for higher speed imaging.

A fly-eye lens 30 formed by arranging a plurality of condensing lenses 32 in a matrix on a plane, a CMOS sensor 10 having a light receiving surface arranged in parallel to the fly-eye lens 30 at a distance corresponding to the focal length of the condensing lenses 32, and a phase calculation device 20 are provided. A center position calculating part 243 calculates the center positions of bright spots (focal points) of focal point images on the light receiving surface by comparison with luminances of adjacent pixels. A centroid data processing part 245 calculates the 0-order moment (total of bright spot luminances in the centroid operating region), first-order moment in the x direction, and first-order moment in the y direction of the luminance in a centroid operating region centered on the bright spot center position. A centroid position calculating part 261 calculates the centroid position of each bright spot based on these centroid data.
