Title:
サンプル抽出された輝度の検知と時間依存性の画像データの非同期検出との同時実施などのためのフォトアレイ
Document Type and Number:
Japanese Patent JP5960279
Kind Code:
B2
Abstract:
The invention relates to a photoarray (1), comprising: a plurality of cells (10), wherein each of said cells (10) comprises a means (20)that is configured to generate a photocurrent (I) being proportional to the intensity (L) of the light impinging on the respective cell (10), and wherein each of said cells (10) comprises a change detection circuit (100) connected to the respective means (20) for generating the photocurrent (I), which change detection circuit (100) is configured to generate an output signal merely in case a change event occurs at which said intensity (L) changes by a threshold amount (T, T′) since the preceding change event from the respective cell (10). According to the invention said means (20) for generating said photocurrent (I) is additionally also used to estimate the magnitude of the said photocurrent (I) being a measure of the brightness of the light at the respective cell (10).
