Patent GB-2523872-A (GB)
Title: A compensation method for a display apparatus
Inventor: MASON STEPHEN PAUL
IPC: H04N9/12
Filed: 2014-11-06
Abstract: A compensation method for a display apparatus is disclosed, the display capable of processing input content having an input resolution to display with a display resolution, the processing being such that, without compensation, for a region of the display screen the content display resolution is lower than the content input resolution, resulting in a reduction in a contrast ratio for content in that region. The method comprises at least partially compensating for the contrast ratio reduction (and associated luminance 42) in advance, by decreasing (reducing) the resolution of input content for display (at the region) on which optical or signal processing may be performed. Content resolution may be decreased by anti-aliasing. The display region may have a lower content resolution than another, different region. A contrast ratio of at least 1.2:1 can be ensured. Compensation can comprise increasing a dimension, size, line width (e.g. to three pixels wide 40) and/or scale of display content. Output luminance 42 may be finely tuned by pixel(s) below maximum level, 44. The method is particularly applicable to partially transparent displays, e.g. comprising a combiner, such as a head up display (HUD) or a helmet-mounted display (HMD) where contrast ratio is affected by surrounding ambient light conditions.

Filed: 2015-01-15
Abstract: There is disclosed a digital printing system and method for depositing ink droplets onto a target surface in dependence upon a received electrical printing signal containing data indicating the desired image to be printed, while improving the uniformity of intended tone reproduction of the printed image. The printing system (300, Fig.1) comprises a multi-nozzle and multi-head print bar (302, Fig.1) that defines print and cross-print directions, an image scanner for scanning a calibration image (700, Fig.8B) printed by the print bar, and a computing system operative during a calibration phase to analyze the output of the image scanner generated by scanning a calibration image. Calibration image data from the scanner is analyzed slice by slice (704A, 704B, Fig.8B) to develop a respective image-correction-function for each slice of the scanned calibration image. During a print run, the image-correction function computed during the calibration phase is applied to the received printing signal, on a slice by slice basis, in order to reduce errors between the desired image and the image printed by the print bar.
