Abstract: The invention is to provide a color-correcting device and method for matching colors of a first image displayed on an image forming apparatus with colors of a second image displayed on a display apparatus. Moreover, the image forming apparatus captures the first image with a plurality of first color values conforming to a first color space. The image forming apparatus also converts the first color values of the first image into a plurality of second color values conforming to a second color space and outputs the second color values to the display apparatus that displays the second image based on the inputted second color values. In one embodiment, the first color space contains R, G, B, color components, and the second color space contains Y, Cr, Cb color components.

Abstract: The present invention provides a focus indication method and system in an image capture device for indicating the photographing state. The method comprises the following steps: press a shutter to be in a first press state to generate a first press signal; start a focus function and a first light emitting state according to the first press signal; then generate a focus complete signal; finish the first light emitting state and start a second light emitting state according to the focus complete signal; generate a second press signal while pressing the shutter to be a second press state; start an image capture function according to the second press signal and finish the second light emitting state before executing the image capture function; generate a third press signal while pressing the shutter to be a third press state; finish the second light emitting state according to the third press signal.

Abstract: A parameter correction method corrects the outputting parameters stored in a capturing device. The outputting parameters provide parameters needed while an outputting device outputs the image file. The method is to output the first reference image file as a reference correction picture by the outputting device, perform the white balance method on the capturing device, capture an image from the picture by the capturing device to form a second reference image file comprising a second reference content data, compare the first and second reference content data to obtain the parameter comparison values, input the values to a predetermined procedure to obtain the correction parameters, update the outputting parameters according to the correction parameters, and store the updated parameters in the capturing device. Finally, when there is one image file being formed later, the updated outputting parameters are appended to the headers of the later files.
