Title: Apparatus for generating thumbnail image of digital video
Inventor: SEO JONG YEOL
IPC: H04N5/91
Filed: 2002-10-18
Abstract: PURPOSE: A device for generating thumbnail images of a digital video is provided to calculate image complexity to discriminate whether an inputted image is a blank image, and to prevent the image decided as a blank image from being generated as a thumbnail image, so that users generate only meaningful and clear thumbnail images. CONSTITUTION: When a DC(Direct Current) pixel value of an (i,j)-th DC image is inputted(201), a blank image discriminator adds a gradient of a horizontal component and a gradient of a vertical component of the pixel value to calculate a gradient of the pixel value(202). The blank image discriminator accumulates the gradient of the pixel value on a variance(203). The blank image discriminator checks whether the DC value indicates an end of a line(204). If not, the blank image discriminator increases a horizontal coordinate value of 'j' by one(205), and the step 201 is returned, and if so, the blank image discriminator checks whether the DC value indicates an end of the DC image(206). If not, the blank image discriminator initializes the value of 'j' and increases a vertical coordinate value of 'i' by one(207), and the step 201 is returned(207), and if so, the blank image discriminator divides the variance by a DC image size to calculate an average gradient of the entire DC image(208). The blank image discriminator compares the average gradient with a preset threshold(209). If the average gradient is smaller, the blank image discriminator discriminates the corresponding image as a blank image and outputs a blank signal of 1(one) to a buffer controller(210). The buffer controller controls a corresponding thumbnail image not to be used(211). If the average gradient is not smaller as a result of the step 209, the blank image discriminator discriminates the corresponding image as a non-blank image and outputs a blank signal of 0(zero) to the buffer controller(212). And the buffer controller controls a corresponding thumbnail to be used(213).
