Abstract
An image processing device is provided. The image processing device includes an image capturing device, a memory device and a microprocessor. The image capturing device captures a first image having plural first pixels. The memory device has a memory space with a size greater than a size of the first image and stores the first image therein. The microprocessor transforms a format of the first image stored in the memory device. The memory device stores the plural first pixels via a first sequence, and the microprocessor transforms the plural first pixels via a second sequence opposite to the first sequence.
Claims18
An image processing device, comprising:
- an image capturing device capturing a high color image having plural first pixels;
- a memory device having a memory space with 1.5 times greater than a first image in size and storing the first image therein;
- and
- a microprocessor transforming a format of the high color image into a true color image comprising plural of second pixels and storing the true color image in the memory device, and also transforming the true color image into the high color image,
- wherein each of the plural first pixels is a 16-bit pixel, each of the plural second pixels is a 24-bit pixel, the memory device stores the plural first pixels via a first sequence, and the microprocessor transforms the plural first pixels via a second sequence opposite to the first sequence.
An image processing method, comprising steps of:
- a. capturing a first image comprising plural first pixels by an image capturing device;
- b. writing the first image into a memory space of a memory device via a first sequence, wherein the memory space has a size greater than a size of the first image;
- and
- c. transforming the first image stored in the memory device into a second image having plural second pixels,
- wherein the first image is transformed into the second image via a second sequence opposite to the first sequence.
An image transforming method, comprising steps of:
- a. providing a first image comprising plural m-bit pixels;
- b. providing a memory device comprising a memory space having a size with n/m times a size of the first image, wherein the n is a positive integer greater than the m;
- c. writing the first image into the memory space via a first sequence by a processor;
- and
- d. transforming the first image into a second image having plural n-bit pixels via a second sequence opposite to the first sequence and filling the memory space by the processor.
An image transforming method, comprising steps of:
- a. providing a first image comprising plural n-bit pixels;
- b. providing a memory device comprising a memory space having a size equal to that of the plural n-bit pixels;
- c. transforming the first image into a second image having plural m-bit pixels via a first sequence by a processor;
- d. modifying the second image to form a third image having plural m-bit pixels;
- and
- e. transforming the third image into a fourth image having plural n-bit pixels via a second sequence opposite to the first sequence and filling the memory space by the processor,
- wherein the n is a positive integer greater than the m.
An image processing device, comprising:
- a memory device comprising a plurality of memory spaces, each of which has a plurality of memory locations consisting of a first group of memory locations and a second group of memory locations;
- an image capturing device for capturing an image, for generating high color image data including a plurality of n-bit pixels corresponding to the captured image, and for storing each of the plurality of n-bit pixels of the high color image data only in the first group of memory locations of the respective memory space;
- and
- a microprocessor for transforming the high color image data into true color image data including a plurality of m-bit pixels corresponding to the captured image, and for storing the true color image data in the memory device such that a respective bit of one of the plurality of m-bit pixels is written into a respective one of the first and the second groups of memory locations in a sequence that a respective one of the first group of the memory locations will be written only when the second group of the memory locations have been fully written, wherein a size of each of the memory spaces is fixed such that each of the plurality of m-bit pixels entirely fills the first and second groups of memory locations of the respective memory space.
