Abstract

An image processing device includes memory and a display panel controller. The memory is used to store digitized image data derived from the image data captured by the image sensor, and the display panel controller is used to process the digitized image data stored in the memory. A portion of the image data captured by the image sensor are directly processed by the display controller and output to the display panel.

Claims

1. An image processing device for a handheld information processing apparatus having an image sensor and a display panel, the image processing device comprising:

a memory, for storing digitized image data derived from the image data captured by the image sensor; and

a display panel controller, for processing the digitized image data stored in the memory;

wherein a portion of the image data captured by the image sensor are directly processed by the display panel controller and then output to the display panel.

2. The image processing device according to claim 1, wherein the memory space is smaller than the image data amount corresponding to a frame of image on the display panel.

3. The image processing device according to claim 1, wherein the time required for inputting each of the image data from the image sensor to the image processing device is not less than the time required for outputting each of the image data from the display panel controller to the display panel.

4. The image processing device according to claim 3, wherein the image data input from the image sensor are processed and transmitted in time to the display panel via the display panel controller.

5. The image processing device according to claim 1, wherein the time required for inputting the image data from image sensor into the image processing device is less than the time for outputting the image data from the display panel controller to the display panel, and the time required for inputting the image data corresponding to one line of image from the image sensor is not less than the time required for outputting the image data corresponding to one line of image from the display panel controller to the display panel.

6. The image processing device according to claim 5, wherein the memory space is not larger than the image data amount corresponding to one line of image on the display panel.

7. The image processing device according to claim 5, wherein the line blanking time between the image data corresponding to each line of image input from the image sensor is used for the display panel controller to transmit the image data to the display panel.
