Patent ID: 7796164

Claim:
A signal reading apparatus that reads an output signal, which includes a plurality of pixel data sequentially arranged, from a solid-state image sensing device, comprising: a plurality of measuring means including a first measuring means and a second measuring means that measure, at respective timings, pixel data included in the output signal from the solid-state image sensing device; a timing generator that generates a clock signal showing a timing at which each of the plurality of measuring means measures the pixel data from the solid-state image sensing device and respectively supplies the clock signal to the plurality of measuring means in order to make the plurality of measuring means sequentially measure the pixel data from the solid-state image sensing device by means of an interleaving operation; and a signal processing circuit that sequentially selects and acquires the pixel data from the solid-stat image sensing device measured by the plurality of measuring means, wherein the timing generator generates a clock signal showing a timing corresponding to the timing at which each of the plurality of measuring means measures the pixel data from the solid-state image sensing device and supplies the clock signal to the signal processing circuit, and the timing generator makes the solid-state image sensing device output the same output signal, including the same plurality of pixel data, multiple times and generates a clock signal to be respectively supplied to the plurality of measuring means in order to make the first measuring means measure a first set of the plurality of pixel data when the solid-state image sensing device firstly outputs the output signal and to make the second measuring means measure the first set of the plurality of pixel data when the solid-state sensing device secondly outputs the output signal.
