A coding apparatus that performs coding processing on each block of an input image comprises a coding unit that executes coding processing using an inter-prediction mode, an intra-prediction mode or a multi-reference prediction mode, an output unit that outputs a result of the coding processing as coded data; and a calculation unit that calculates a first coding cost if the block is coded in the inter-prediction mode and a second coding cost if the block is coded in the intra-prediction mode using a predetermined function. The coding unit executes the coding processing using the multi-reference prediction mode if a difference between the first coding cost and the second coding cost is equal to or less than a threshold, and using the prediction mode with a smaller one of the first coding cost and the second coding cost if the difference is larger than the threshold.

Coding apparatus and method, and storage medium

An image processing apparatus obtains a plurality of pieces of image data with different exposure amounts and then performs a level-conversion of the image data by applying input/output characteristics thereto. The apparatus encodes the image data whose level has been converted and decodes the encoded image data. The apparatus further applies inverse characteristics of the input/output characteristics to the decoded image data and then generates combined image data. In generating the combined image, the input/output characteristics are set in accordance with a combining ratio of each of the image data.

An information processing apparatus obtains a measurement value D of the distance between the object and information processing apparatus using a human detection sensor, and detects the object as a user (user detection state ST) by comparing the measurement value D and a predetermined threshold value. The power mode of the information processing apparatus is set to a standby mode if a user has been detected, and is set to a sleep mode if a user has not been detected. If a state in which a user has been detected continues for a predetermined time, the information processing apparatus changes the sensitivity of the human detection sensor by changing the threshold value for the detection state determination such that the object detected by the human detection sensor is no longer detected as a user.
