Abstract
An image sensing system comprising: a storage device, comprising at least two first registers, wherein a number of the first registers following a first direction of the storage device is larger than a number of the first registers following a second direction of the storage device; a filter, comprising at least two second registers; and an SIPO (serial in parallel out) circuit, coupled between the storage device and the filter.
Claims16
An image sensing system, comprising:
- a storage device, comprising at least two first registers, wherein a number of the first registers following a first direction of the storage device is larger than a number of the first registers following a second direction of the storage device;
- a filter, comprising at least two second registers;
- and
- an SIPO (serial in parallel out) circuit, coupled between the storage device and the filter;
- wherein the image sensing system further comprising;
- a pixel array, comprising at least one pixel, configured to generate image sensing data;
- an ADC (Analog to Digital Converter), configured to convert the image sensing data to digital image sensing values;
- wherein the filter and the storage device respectively receives at least partial of the digital image sensing values;
- wherein the digital image sensing values are shifted to the first registers and correspondingly copied to the second registers until a first row of the first registers is filled up with the digital image sensing values.
An image sensing data processing method, applied to a storage device comprising at least two first registers and a filter comprising at least two second registers, comprising:
- reading image sensing data in the first registers following a second direction of the storage device in series, wherein a number of the first registers following a first direction of the storage device is larger than a number of the first registers following the second direction of the storage device;
- and
- writing the image sensing data to the second registers based on an address of the first registers which is read in series;
- wherein the image sensing system further comprises:
- a pixel array, comprising at least one pixel, configured to generate the image sensing data;
- an ADC (Analog to Digital Converter), configured to convert the image sensing data to the digital image sensing values;
- wherein the digital image sensing values are shifted to the first registers and correspondingly copied to the second registers until a first row of the first registers is filled up with the digital image sensing values.
