The applicant proposes a method and an apparatus to realize a faster, easier and more precise multispectral digitalization of films. The proposed method and apparatus ensure quality control of the multispectral film digitization using sensors and can correct the digital images for film shrinkage and deformation. This can allow for efficient digitization of films which can enable an effective automatization of the mass safeguarding of archived films. The proposed film digitizer apparatus can comprise a novel and improved light source module, which comprise a light assembly that can allow for better illumination of the film and shorter required exposure time that can lead to lower acquisition time for each of the various wavelength image acquisitions for each film image. Monitoring of the spectral distribution and/or the temperature of the light sources can ensure quality control of the digitalization.

Described herein is a processing apparatus, film scanner and associated method, such as a processing apparatus for processing motion picture film, comprising an identification module for identifying selected regions of one or more digital images or digital video clips of the film; and an image modification module configured to access or produce data; and modify at least one of the one or more digital images or the digital video clip so as to provide the data in at least one of the selected regions. Advantageously, the selected regions correspond to perforations in the film.

Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for video coding with an intra prediction coding mode. In one method, a decoder determines prediction sample values of one or more video blocks based on position-dependent intra prediction combination (PDPC) operations for one or more intra predictions of the one or more video blocks to unify the PDPC operations in the intra prediction coding mode; and in response to determining that a direct current (DC) mode, a planar mode, or an angular mode is applied in the one or more intra predictions of the one or more video blocks, the decoder may disable the PDPC operations respectively for the DC mode, the planar mode, or the angular mode to unify the PDPC operations in the intra prediction coding mode.
