[Problem] To provide an image processing apparatus and an image processing method.
[Solution] An image processing apparatus is provided. The image processing apparatus includes a decoding unit configured to generate a decoded image by decoding a coded stream, a determination unit configured to adopt a block boundary of the decoded image as a target and determine deblocking filter application necessity with respect to color difference components of the decoded image based on boundary strength that is calculated using a color difference related parameter related to a color difference, and a filtering unit configured to apply a deblocking filter to color difference components of pixels located in a vicinity of the block boundary based on a determination result of the deblocking filter application necessity.
