Patent number: 8842220Abstract: This invention enables, for example, reduction of motion blur in a hold-type display device and reduce flicker in an impulse-type display device by a simple process. For this purpose, an LPF filters a frame of input image data (A[i]) to generate low-frequency image data (L). A subtractor and an adder generate high-frequency image data (SH). Another adder adds the low-frequency image data (L) from a delay circuit to subsequent low-frequency image data. A divider halves the sum to generate low-frequency averaged image data (SL). A switch alternately outputs the high-frequency image data (SH) and the low-frequency image data (SL) every time a frame of image data is input. As a result, the apparatus of this invention can generate output image data having a frame rate twice that of the input image data.Type: GrantFiled: March 12, 2013Date of Patent: September 23, 2014Assignee: Canon Kabushiki KaishaInventor: Kiwamu Kobayashi

Patent number: 8749708Abstract: In order to distribute low-frequency component image data L in image data for one frame to first and second sub-frames respectively as L1 and L2, a distribution of L2 in the low-frequency component image data L is decided. This decision is made based on a non-linear curve, so that when the low-frequency component image data L falls within a low-level region, a distribution rate of L2 is decreased, and when the low-frequency component image data L falls within a high-level region, the distribution rate of L2 is increased within a range that does not exceed 0.5. In this way, a negative-side clipping phenomenon of high-frequency components is suppressed in the low-level region, and flickers are suppressed in the high-level region.Type: GrantFiled: December 7, 2009Date of Patent: June 10, 2014Assignee: Canon Kabushiki KaishaInventor: Kiwamu Kobayashi

Patent number: 8531601Abstract: This invention enables reduction of moving blurring in a hold-type display device and reduce flicker in an impulse-type display device, and also enables to suppress distortion such as ghost or tail-blurring in pursuit. A LPF generates low-frequency image data from input frame. High-frequency emphasized image data is also generated using a subtractor and an adder. A SizeDown unit reduces the low-frequency image data to decrease the number of pixels. A motion detection/motion application unit performs motion detection and motion application from the reduced image data of the frame of interest and that of the next frame to generate reduced image data located at the intermediate position between them. A SizeUp unit enlarges the generated reduced image data. Another LPF filters the enlarged image data and outputs the result as low-frequency image data. A switch alternately outputs the high-frequency emphasized and the low-frequency images at a speed twice the input frame rate.Type: GrantFiled: August 6, 2008Date of Patent: September 10, 2013Assignee: Canon Kabushiki KaishaInventor: Kiwamu Kobayashi

Patent number: 8487919Abstract: In an image display apparatus which displays a picture by inverting the drive polarity for each sub-frame, when the pictures of adjacent sub-frames are different from each other, image data is generated to prevent accumulation of electrical charges in each display element. For this purpose, the first and second sub-frames are generated from a frame of interest of a moving picture. The difference between the pictures of the first and the second sub-frames is detected. A correction value is calculated by subtracting from the difference a cumulative value multiplied by a predetermined coefficient. A value obtained by subtracting the correction value from the difference is accumulated as the cumulative value. The pictures of the first and second sub-frames are corrected by the correction value.Type: GrantFiled: August 4, 2008Date of Patent: July 16, 2013Assignee: Canon Kabushiki KaishaInventor: Kiwamu Kobayashi
