Abstract
A radiation imaging apparatus includes a pixel array including n pixel rows, where n≥3, and a driving circuit configured to scan the pixel array from a first row toward an nth row, counting from one end of the pixel array. In a case where a region of interest is included in a partial region composed of pixel rows from an ith row to a jth row, where 1<i≤j<n, the driving circuit starts scanning of the pixel array from the first row, and starts scanning of the pixel array from the first row again during scanning of pixel rows from a (j+1)th row to the nth row.
Claims11
A radiation imaging apparatus, comprising:
- a pixel array including n pixel rows, where n≥3;
- and
- a driving circuit configured to scan the pixel array from a first row toward an nth row, counting from one end of the pixel array, wherein
- in a case where a region of interest is included in a partial region composed of pixel rows from an ith row to a ith row, where 1<i≤j<n, the driving circuit
- starts scanning of the pixel array from the first row, and
- starts scanning of the pixel array from the first row again during scanning of pixel rows from a (j+1)th row to the nth row.
A method of controlling a radiation imaging apparatus that includes a pixel array including n pixel rows, where n≥3, and a driving circuit configured to scan the pixel array from a first row toward an nth row, counting from one end of the pixel array, the method comprising:
- in a case where a region of interest is included in a partial region composed of pixel rows from an ith row to a ith row, where 1<i≤j<n,
- starting scanning of the pixel array from the first row;
- and
- starting scanning of the pixel array from the first row again during scanning of pixel rows from a (j+1)th row to the nth row.
