Imaging apparatus with improved pre-processing
The imaging apparatus include a solid-state imaging device which has a plurality of pixels and outputs a pixel signal corresponding to a formed image of a subject as an image data; an image-capturing processing unit which outputs a pre-processed image data that is obtained by performing pre-processing on a part of the image data input from the solid-state imaging device, and an un-processed image data except the part of the image data from the image data input from the solid-state imaging device; and a storage unit which stores the pre-processed image data and the un-processed image data.
1. An imaging apparatus, comprising:
a solid-state imaging device which has a plurality of pixels and outputs a pixel signal corresponding to a formed image of a subject as an image data;
an image-capturing processing unit which outputs a pre-processed image data that is obtained by performing pre-processing on a part of the image data input from the solid-state imaging device, and an un-processed image data except the part of the image data from the image data input from the solid-state imaging device; and
a storage unit which stores the pre-processed image data and the un-processed image data,
wherein the image-capturing processing unit includes:
a pre-processing section which has a line memory, which stores the image data of which amount is smaller than a data amount of the image data in a first direction of the image, and outputs the pre-processed image data obtained by performing pre-processing on the image data of the image divided within a range of the data amount of the image data that is capable of being stored in the line memory;
a first data transmission section which transmits the pre-processed image data to the storage unit;
a second data transmission section which transmits the image data in the first direction of the image that has not been pre-processed by the pre-processing section, to the storage unit as the un-processed image data;
a data acquisition section which acquires image data stored in the storage unit; and
a selection section which outputs the image data input from the solid-state imaging device or the image data acquired by the data acquisition section to at least one of the pre-processing section and the second data transmission section,
wherein, in a first operation, the first data transmission section transmits first pre-processed image data, which is obtained after the pre-processing section performs pre-processing on the image data of a first image obtained by dividing the image within a range of the data amount of the image data that is capable of being stored in the line memory, to the storage unit, and the second data transmission section transmits the image data of a second image obtained by dividing the image that has not been pre-processed by the pre-processing section, as first un-processing image data, to the storage unit, and
in a second operation after the first operation is completed, the data acquisition section acquires the first un-processing image data, stored in the storage unit, the selection section outputs the first un-processing image data, to the pre-processing section, and the first data transmission section transmits second pre-processed image data, which is obtained after the pre-processing section performs pre-processing on the first un-processing image data, to the storage unit.
2. The imaging apparatus according to claim 1 ,
wherein the image-capturing processing unit further includes a conversion section that performs conversion processing for converting the pre-processed image data and outputs converted image data after the conversion processing.
3. The imaging apparatus according to claim 2 ,
wherein the conversion section includes a resizing section that resizes an image corresponding to the pre-processed image data to an image, which has a size set in advance in the first direction and a second direction perpendicular to the first direction, and outputs the converted image data of the resized image.
4. The imaging apparatus according to claim 3 ,
wherein, in the second operation, the first data transmission section transmits second pre-processed image data, which is obtained after the pre-processing section performs pre-processing on the first un-processing image data, to the storage unit, and the second data transmission section transmits first converted image data, which is obtained after the resizing section performs a resizing process on the second pre-processed image data, to the storage unit, and
in a third operation after the second operation is completed, the data acquisition section acquires the first pre-processed image data stored in the storage unit, the selection section outputs the first pre-processed image data to the resizing section, and the second data transmission section transmits second converted image data, which is obtained after the resizing section performs a resizing process on the first pre-processed image data, to the storage unit.
