Title:
SOLID-STATE IMAGE CAPTURING ELEMENT, IMAGE CAPTURING DEVICE, AND METHOD FOR CONTROLLING SOLID-STATE IMAGE CAPTURING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/010036
Kind Code:
A1
Abstract:
The purpose of the present invention is to enhance processing speed in a solid-state image capturing element for performing signal processing on a portion of image data. According to the present invention, a repeater is connected to a cluster in which a prescribed number of pixels are arrayed and transfers a digital signal indicating a time within a prescribed time period. A comparator compares an analog signal according to light exposure with a reference signal that fluctuates over the prescribed time period and outputs the result of the comparison. A latch circuit acquires the digital signal from the repeater and holds the digital signal. A latch control circuit controls the latch circuit when the result of the comparison is inverted so as to hold the digital signal and controls the latch circuit at a timing indicated by a prescribed output timing signal so as to output the digital signal to the repeater. When the output of the digital signal is set as effective by a prescribed output enable signal, an enable control unit supplies the output timing signal to the latch control circuit.
