Abstract
An image data processing apparatus includes a data size conversion device that changes a data size of an image data at an optional ratio, the image data has a plurality of pixels each of which includes any one of a plurality of color components, and the plurality of color components being arranged in a specific order. The data size conversion device newly calculates a value of color component of each pixel after changing the data size based upon values of color components of a plurality of same color pixels before changing the data size, while maintaining the order of arrangement of the plurality of color components.
Claims10
An image data processing apparatus comprising:
- a data size conversion device that changes a data size of an image data at an optional ratio, the image data having a plurality of pixels each of which includes any one of a plurality of color components, the plurality of color components being arranged in a specific order, wherein
- said data size conversion device newly calculates a value of color component of each pixel after changing the data size based upon values of color components of a plurality of same color pixels before changing the data size, while maintaining the order of arrangement of the plurality of color components.
An image data processing apparatus, comprising:
- a color separation device in which a plurality of color filters, each of which passes light of one of a plurality of color components, are arranged in a specified order, and which separates an image of a subject into said plurality of color components;
- an imaging device which images the image of the subject which has been color-separated by said color separation device with a plurality of pixels;
- an A/D conversion device which A/D converts an image signal outputted from said imaging device;
- and
- a data size conversion device which changes a data size of the image data after A/D conversion at an optional ratio, wherein
- said data size conversion device newly calculates a value of color component of each pixel after changing the data size based upon values of color components of a plurality of same color pixels before changing the data size, while maintaining the order of arrangement of the plurality of color components.
An electronic camera comprising:
- a color separation device in which a plurality of color filters, each of which passes light of one of a plurality of color components, are arranged in a specified order, and which separates an image of a subject into said plurality of color components;
- an imaging device which images the image of the subject which has been color-separated by said color separation device with a plurality of pixels;
- an A/D conversion device which A/D converts an image signal outputted from said imaging device;
- and
- a data size conversion device which changes a data size of the image data after A/D conversion at an optional ratio, wherein
- said data size conversion device newly calculates a value of color component of each pixel after changing the data size based upon values of color components of a plurality of same color pixels before changing the data size, while maintaining the order of arrangement of the plurality of color components.
An image data processing method comprising:
- obtaining an image data that has a plurality of pixels each of which includes any one of a plurality of color components which are arranged in a specific order;
- and
- changing a data size of the image data at an optional ratio, wherein
- a value of color component of each pixel after changing the data size is newly calculated based upon values of color components of a plurality of same color pixels before changing the data size in order to change the data size while maintaining the order of arrangement of the plurality of color components.
A computer-readable computer program product containing a control program for image data size conversion processing, the control program comprising instructions of:
- obtaining an image data that has a plurality of pixels each of which includes any one of a plurality of color components which are arranged in a specific order;
- and
- changing a data size of the image data at an optional ratio, wherein
- a value of color component of each pixel after changing the data size is newly calculated based upon values of color components of a plurality of same color pixels before changing the data size in order to change the data size while maintaining the order of arrangement of the plurality of color components.
