Abstract: In order to appropriately control the image quality of an intended specific region in an image without delaying an encoding process, an image processing apparatus includes a determination unit configured to determine a specific region in a first image targeted for the encoding process on the basis of (a) a time difference between a first time associated with the first image and a second time associated with a second image in which an object has been detected by a detection unit before the encoding process is executed on the first image, and (b) information on a region corresponding to the object detected by the detection unit in the second image, and executes, on the first image, the encoding process of varying image quality between a region corresponding to the specific region determined by the determination unit, and any other region.

Abstract: An image processing apparatus according to the present invention is configured to encode frames forming a moving image using temporal hierarchies, and includes an acquisition unit configured to acquire information related to a temporal hierarchy corresponding to an encoding target frame, a determination unit configured to determine, based on the information related to the temporal hierarchy acquired by the acquisition unit, whether to use an encoding parameter based on a bit rate of at least one past frame encoded before the encoding target frame is encoded, and an encoding unit configured to encode the encoding target frame using the encoding parameter based on the bit rate of the at least one past frame.

Abstract: An amount of code is reduced for blocks in which visible degradation is not easily susceptible, while a large amount of code is assigned to blocks whose degradation in image quality is easily perceptible thereby suppressing the number of blocks for which a process is performed to achieve high quality image and thus suppressing an increase in the total amount of code. An input image is encoded in units of blocks. A block evaluation value for the block is calculated. The block is divided into N sub-blocks where N is equal to or greater than 2, and a sub-block evaluation value is calculated for each sub-block. A quantization parameter for the block is controlled based on the block evaluation value and the sub-block evaluation values.

Abstract: An image of a prescribed frame of images of respective frames is set as a target image, and an area including a prescribed pattern is detected from the target image as a specific area. An image other than the target image is set as a non-target image, and the specific area in the non-target image is predicted. The images of the respective frames are encoded so that the specific area is encoded to have higher image quality than an area other than the specific area. In encoding, the images of the respective frames are encoded so that the specific area in the non-target image is not referred to from another frame.
