Methods for implementing Adaptive Color Transformation (ACT) during image / video encoding and decoding are described. Example methods for video processing include, for a conversion between a video comprising blocks and a video bitstream, determining that the block size is greater than the maximum allowed size of the ACT mode, and performing the conversion based on this determination, wherein, in response to the block size being greater than the maximum allowed size of the ACT mode, the block is divided into multiple sub-blocks, and wherein each of the multiple sub-blocks shares the same prediction mode, and the ACT mode is enabled at the sub-block level.

To provide systems and methods for signaling downsampling offset information in video coding.SOLUTION: In a system, a device (video image decoding device 600) configured to signal downsampling offset information for coded video in a phase indication information message receives the phase indication information message to be applied to a current cropped decoded picture and persists for all subsequent pictures of a current layer in output order with the same cropped picture width and cropped picture height as the current cropped decoded picture until a picture in the current layer with an associated phase indication information message and the same cropped picture width and cropped picture height as the current cropped decoded picture is output and follows the current picture in output order.SELECTED DRAWING: Figure 11

A multi-aperture imaging system comprising a first camera with a first sensor that captures a first image and a second camera with a second sensor that captures a second image, the two cameras having either identical or different FOVs. The first sensor may have a standard color filter array (CFA) covering one sensor section and a non-standard color CFA covering another. The second sensor may have either Clear or standard CFA covered sections. Either image may be chosen to be a primary or an auxiliary image, based on a zoom factor. An output image with a point of view determined by the primary image is obtained by registering the auxiliary image to the primary image.
